Does rising damp cause mould? What are the signs of a problem?

Does-rising-damp-cause-mould

What is rising damp?

Rising damp occurs when excess moisture from the ground absorbs up into porous building materials such as stone, brick, earth, mortar and into the structure of the building. The moisture evaporates from either face of the wall, allowing more to be drawn from below. Rising damp is common in older buildings, but can also occur in more modern buildings if your damp-proof course has been damaged.

Though rising damp may cause unsightly aesthetic damage, it can also cause the structure of the building to be compromised and cause you bigger problems in the future. Damp walls also encourage mould growth, which can lead to health problems for occupants.

You can often identify rising damp by just looking at and touching your walls, though if you are unsure whether there is a real problem, it is best to have a water damage professional do an assessment.

What are the tell tale signs of rising damp?

There are a number of typical signs that can identify rising damp including:

TIDE MARKS AND DAMP STAINING

One of the most common signs of rising damp are tide marks left on walls. Tide marks are caused by evaporation and salts from the ground. You will usually notice them anywhere up to one metre above the skirting board.

If you do not notice tide marks, another frequent tell tale sign is damp patches or staining. usually, these damp patches are yellow to brown in colour and similar to tide marks, you will notice them again up to one metre above the skirting board.

PEELING WALLPAPER

If you’ve noticed wallpaper coming off or peeling from the wall there may be a damp issue. Usually the wallpaper will start coming loose from the skirting board first, and the corner of the wallpaper may be curved up.

DECAYED SKIRTING BOARDS

As with many forms of dampness, rising damp has the potential to cause rot within timbers it comes into contact with. Look out for skirtings that are cracked, easily crumble or localised fungus growing on or creeping out of the side. Also, look out for damaged or flaky paint.

SALTS WITHIN THE PLASTER

Fluffy deposits in the plaster are a sign of salts within the plaster. This is another sign of rising damp. These salts are washed out of your bricks and into your plaster leaving what can often look like blistering patches on your walls.

BLACK MOULD

If you start to notice black mould appearing above your skirting board it is a clear sign that there is some form of moisture issue affecting the area. This is especially true if you have no other black mould within the property and the black mould you see is localised from the skirting board to up to one metre above.

Yes, rising damp can cause mould!

As you can see above, rising damp can cause mould, with black mould being the most common culprit. Mould can cause detrimental health effects for you and your family, or the occupants of your property. Plus mould spores can spread once they take hold.

Identifying rising damp

Sometimes rising damp can be misdiagnosed. Often a leaking pipe or gutter can also cause moisture issues within the home.

How Does Mould Grow?

How-Does-Mould-Grow

What conditions in the home are best for mould growth?

Keeping mould from growing in your home is really important for the health of you and your family. The first step in keeping mould under control in your home is discovering what areas and conditions are best for mould growth. Mould spores thrive and multiply in moist wet conditions. How does mould grow? Mould grows easily when moisture and humidity are present. Mould spores search for a damp surface in your home so that they can begin to grow and thrive.

What does mould need to Grow? Mould spores need three things in order to grow and multiply. That being nutrients, moisture and time. Mould can start to grow on a surface in the right conditions in as little as 24 hours.

How can I prevent mould growth in my house?

Mould spores are everywhere. They are carried by air currents throughout your home. They look for a moist dark environment where they settle and multiply. In order to prevent mould growth in your home is to maintain your home in order to keep out excess moisture. This includes having your roof checked regularly for leaks, have plumbing maintained and drying any spills, leaks or flooding that may occur.

It is recommended that home humidity levels are kept to to 30-50% to prevent mould growth. Mould also grows efficiently in warmer more humid climates, and blossoms at 25 to 30 °C. Condensation on or around windows can be an indication that your home’s moisture levels are too high. Two ways a homeowner can decrease the humidity in the home is by increasing ventilation and buying a dehumidifier.

To increase your home’s ventilation, be sure to use correctly vented exhaust fans while in the kitchen and bathroom, to reduce the moisture in the air. Assure that ventilation throughout your home is adequate to keep up with moisture levels, consider sub-floor and roof ventilations as well as high quality bathroom and laundry ventilation systems. If your home is still struggling with higher than advisable humidity levels, consider buying a dehumidifier to maintain a optimum levels of humidity resistant to mould growth. Make sure you purchase a dehumidifier that will cover the square footage necessary for your residence.

Attending to moisture leaks in your home

If your home has water leaks, it is likely that mould will follow. Leaks can occur in pipes, roofs, appliances and windows. Because leaks are usually undetectable behind a wall or in the ceiling, leaks can have the advantage of time to release water into your home continuously. This constant influx of water can increase mould growth considerably. To look for leaks in your home, be on the lookout for –

  • water stains
  • warping or bowing of walls and architraves
  • deterioration of wood
  • bubbling or cracking paint or wallpaper
  • Symptoms of mould sickness in your family

Flooding and other water damage

Flooding is a serious risk factor for mould growth. When excessive amounts of water enter a building and remain for a period of time, mould will begin to develop in as little as 24 hours. Therefore prompt action is needed in the event of a flood to prevent or reduce mould damage in your home.

You may wish to hire a professional to restore your home after a flood. This is a very good option because a professional water damage specialist has the credentials and equipment to deal with flood and water damage in a home most flood damage specialists will even deal with your insurance for you.

What is stachybotrys chartarum?

Stachybotrys chartarum is a toxic mold/fungi that commonly grows in homes and buildings and can cause “sick building syndrome,” this is medical condition where people develop symptoms of illness that go away or improve when they are not in the building that contains the mould issue. Stachybotrys chartarum is greenish-black in colour and can be slimy to the touch. This harmful mould likes to grow on high-cellulose material such as dry wall, carpet, wall paper, fiberboard, ceiling tiles, thermal insulation, etc therefore it is commonly found growing indoors. Some other common moulds that grow indoors are Cladosporium, Penicillium, Aspergillus, and Alternaria. Indoor moulds grow when there is water damage, too much moisture or humidity, water leaks, or flooding.

Where does mould grow best?

The kitchen and bathroom are often places in your home that mould likes to grow. The humidity from baths, showers, cooking, and washing dishes is often higher in these rooms. Kitchens and bathrooms usually have more plumbing than other areas of your home which could develop leaks within the walls. If you have a roof leak, the ceiling could be harbouring mould. It is important to check for leaks in these areas, monitor the humidity, set up proper ventilation and dry up any condensation that develops. Be sure to also check for mould in air conditioning and heating ducts, washing machines, dishwashers, and in the shower and bathtub.

What are the symptoms of indoor mould exposure?

Sometimes you can’t see mould because it is within a wall or in the ceiling cavity. However, if you’ve been experiencing some of these symptoms that improve when you are no longer in the home, you may want to have your house checked by a mould professional.

  • skin rash
  • eye irritation
  • headaches
  • fatigue
  • sore throat
  • shortness of breath
  • runny or stuffy nose
  • sneezing
  • cough

You should talk to your doctor if you are experiencing any of these symptoms and consider having your home tested by a mould expert.

Preventing mould Indoors

Prevention is better than cure and it It is always better to take action to prevent mould through keeping your home in the right conditions rather than dealing with an expensive and unhealthy mould issue in the future. The right ventilation systems and performing routine maintenance can save a lot of money by avoiding mould contamination in the long run. The following six steps will significantly reduce your risk of mould or other issues in the home.

  • Monitor indoor humidity
  • Clean and repair roof gutters
  • Dry wet materials quickly
  • Fix leaks
  • Increase ventilation
  • Have your roof checked regularly

So, how do we prevent mould growing in our house? The key is to reduce the conditions that are best for mould growth. What does mould need to grow? Nutrients, moisture, and time If you control the moisture, clean up and dry water damage, and reduce the time water or moisture is allowed to remain (within 24 hours), mould will have less of a chance to take up residence in your home.

Can I paint over mould?

Can-I-paint-over-mould

If you have a mould issue on the walls of your home, whether it be internal or external it can look unsightly.

Mould happens to grow and multiply very fast so if your walls are damp with excess moisture, they may quickly become covered in it. You may be looking for a quick fix and thinking “can I just paint over mould?

Painting over mould is quite a common method to disguise it. But the problem is – you are only hiding the issue temporarily. Some people choose to paint over mould in to order to hide the awful stains that appear on their walls. Unfortunately the people that do this have no idea of the health implications of mould in the home. Sadly it is common that homeowners, landlords and even property managers often paint over mould because it is a quicker and cheaper way to hide the problem. But the thing is, it doesn’t solve the problem. It doesn’t kill the mould, and will only hide it until it breaks through the paint surface again.

What are the signs of painted over mould?

If you suspect your walls may have mould under the paint, you may be able to smell a stale musty smell and you could see visible signs in the affected areas. You may notice that the paint is bubbled, cracked or chipped. You may notice slightly darker patches in the paint. White or lighter coloured paint could have gained a yellow tinge as a sign of water damage. You may also have noticed the walls or ceiling aren’t completely flat, they could bubble or bow out which is also another sign of water damage.

A lot of mould in the home has been grown from past water damage and if you there could be mould growth behind any painted areas in your home you will need to find out the source of the mould problem and have it remediated – not paint over it. If not attended to properly, mould can cause serious health problems for the inhabitants of your home.

What is mould remediation?

Mould remediation is when the source of the mould problem is identified and rectified. The mould is killed and removed.

So many hardware stores advertise “mould resistant paint” this does not mean you can buy this paint and paint over your mouldy areas. This is unfortunately something that confuses people who are unaware, they think this paint will kill mould and stop it from re-appearing. You must properly kill and remove mould before repainting. If the mould is not remediated properly, it will keep growing and will eventually break back through the paint surface. Plus if the source of the mould is not dealt with, it will only keep coming back.

If you do suspect that there is mould growth underneath the paint on your walls or ceilings, you should definitely look to book in a mould remediation specialist to start mould testing and inspection. The specialist mould technician will carry out an assessment of your home to determine the source of the mould and the extent of the mould damage as well as recommend any repairs that may need doing once the mould source has been dealt with. Mould can grow very fast in the right conditions – even under paint, even under “mould resistant paint”.

Mould spores spread easily and quickly. So while you think you could tackle the mould yourself, sometimes it is just best for the sake of your health and those you love to just hire a professional to come in and do the job right. Especially if there is a hidden source of mould deep within the walls which is most likely caused by water damage, a professional mould specialist will know exactly where to look and how to deal with it quickly and efficiently.

What if I’m renting a mouldy property?

If you are renting a property that you suspect has a mould problem and your landlord or property manager has taken the quick fix route and decided to paint over it rather than deal with it properly, you have every right to ask for professional mould remediation. Mould can affect the health of all inhabitants of the property and it is definitely in the best interest of the landlord and property manager to look after the health of their tenants. The legal ramifications down the track can become very costly should they choose to just cover up the problem.

So, should I just paint over mould?

No! Some think that mould remediation can be costly. But the longer you leave it, the most costly it can become. Not only in possible structural damage, but the damage to your health and that of your family.

Paint does not and will not kill mould plus the mould will come back anyway! Painting over it will not stop the source of the mould. Mould will continuously grow under the paint until it is killed, removed, and the source of the mould stopped. If you suspect mould, book in a professional mould inspection to ensure the mould is identified and the source of the water damage is discovered. Once you know the extent of the water damage or source of the mould you can commence remediation and repairs.

Improving The Air Quality Within Your Home

mould_pro

Everyone wants to live a healthy happy life. But what if the air you are breathing inside your home could be harming you and your family in various ways. Nothing in this world is more important than the air you breathe, so you should make it your aim this year to improve the air quality in your home. Here are some tips to help with your planning.

What’s your indoor air quality like?

Not many of us stop to think about the pollution INSIDE our homes – the air that is circulating within our home on a daily basis . We all know that traffic and industry cause pollution in the air outside, but what is happening inside? Air in a poorly ventilated home can be just as polluted if not more than the air outside. When indoor air quality is poor, it is simply not as clean, fresh and pure as it should be.

What are the main causes of poor indoor air quality?

The air quality inside a building is affected by various factors. Pollution from the outdoors coming in through windows and doors is one factor, especially in cities and densely populated areas.

Though other factors that affect our indoor air quality are:

  • Gases are given off by heating and cooking appliances
  • Volatile organic compounds from cleaning products, paints and plastics
  • Smoke and other airborne particulates
  • Allergens such as mould and dust all contribute to bad indoor air quality
  • Radon gases from underground can also penetrate into your home and reduce air quality if you live in an area where these naturally occurring gases are more highly concentrated
  • Bad indoor air quality will be worsened in a situation where there is little or no natural air flow within the home, which can lead to condensation build up, damp and mould.

What problems can poor indoor air quality cause in your home?

As time goes by lack of airflow and poor quality air can begin to damage the structure of your home and its fittings and fixtures. If stagnant air sits around your home for too long, you will come across all sorts of problems. Condensation can form in bathrooms and kitchens and can create damp problems. Mould, which is a serious allergen, will grow and flourish. Even in houses that do not suffer from damp, bad air quality can still cause issues. Carpets, wallpaper, curtains and soft furnishings can all become permeated with nasty, musty smells that can be hard to remove. Eventually poor air quality can damage the interior of your home and change the way it looks and smells long term.

How is poor indoor air quality damaging our health?

Poor indoor air quality can cause chronic health problems, especially when caused by the number one problem: Mould. The lungs and heart are the main organs affected. Scientific studies have shown the link between bad indoor air pollution and health issues. Cooking can emit nitrogen dioxide which can cause a range of breathing issues. Whilst VOCs can cause a decrease in lung function setting off asthma, wheezing and an increased risk to your heart and whole respiratory system. Nasal irritation is very common as well as dry mouth, a constricted throat and scratchy sore eyes.

How to improve the air quality in your home

The good news is it is easy to improve on the air quality within your home. The most simplest way is to improve on your home ventilation and improving air flow rates in your house, as this will improve air quality as a start. Sophisticated technology in ventilation systems will constantly monitor the humidity levels and flow rates of the air in your home, so the system always works efficiently and effectively. Heat Recovery ventilation solutions will not only help you improve indoor air quality but also help you save money on electricity. Our sister company, Zephyr Ventilation can advise you on the right type of ventilation system needed for your home.

An expert mould check and remediation, if needed, plus a good ventilation system are the first steps towards better air quality. You can then further enhance your living space and improve air quality further by taking the following measures:

  • Introduce living plants which are natural air purifiers
  • Remove carpets and have natural, hard flooring instead
  • Use only natural household cleaning products
  • Use paints and other decorating materials that are low in VOCs
  • Reduce the amount of plastic and the number of new items coming into your home
  • Live a more sustainable and natural way of life.

You can now plan some positive steps to improve the air quality in your home so as to enjoy the benefits of cleaner, fresher air and a healthier home for you and your family.

Inviting mould into your home through your laundry

mould_pro

The Laundry and Mould

What does mould need to thrive? A warmth moist environment and something to cling to. It is no wonder then that that the laundry and dirty clothes hampers, in fact, are the perfect regions for mould to grow, as they commonly provide mould spores daily access to a lavish supply of decaying organic material such as dirt, dust, urine, hair, body oils, sweat, food, etc to feed on and, as well as generally being a moist environment.

With all that being said, your chances of acquiring mould growth in your laundry or dirty clothes hampers are especially high. Sometimes depending on the climate that you reside in, having mould come into your home through your laundry can be a constant battle, especially in the higher humidity climates or in homes that have moisture issues.
Even if a home does not suffer from moisture issues, the usual mundane daily tasks performed within your laundry could be inviting and maintaining mould growth.

What do you do with your dirty clothes?

When your family removes their soiled clothes, what do they do with them? Do they sit in a heap in the corner of a room? On the floor of the bathroom? Get pushed under the bed or shoved to the bottom the wardrobe? Or do they all comply and pop it in the designated laundry hamper?

No matter where the clothes are placed, the important part is what state the dirty clothes were left in when they were placed there and how long it took for them to make it to the washing machine!

Dirty washing can be soiled with food

You may have mopped up a milk spill with a towel. Your child may have spilled their weetbix all over their pjs at breakfast. You may have accidentally dumped your coffee all down your shirt first thing this morning…. You get the idea… If this happens, throw it in the wash that day, not at the end of the week.

Dirty washing can be soiled with sweat

Mould loves bodily fluids… Yes. So those gym clothes need to be washed TODAY. Those sweaty work clothes need to be washed as soon as possible, and yes the kids sweaty school uniforms need to go into the machine at your earliest convenience. While these things may not feel damp to touch, bundling them up and letting them sit in the hamper for a few days is not a good idea.

Dirty washing can be wet

Your toddler may have wet their pants, or a wet towel may be sitting at the bottom of the basket from this mornings shower. More and more items could end up piled up on top of this and the items on the bottom stay wet. The wet items will likely be forgotten about and end up being left to become a mould-breeding playground.

Within the clothes hamper

Moist laundry or severely soiled laundry thrown into the hamper, or piled onto the floor somewhere can cause a spot of trouble. This is because as mentioned, more and more dirty items are usually piled on top and that towel that was put in early this morning never dries!

Some days life is busy, crazy even, and you may not be able to put a wash on every day. Yes, guarantee more often than not that wet towel will be forgotten about. Sometimes that wet or soiled item may be a different fabric or colour that can’t be washed with other items. That may mean you will have to delay its washing even further.

It is also important to look at the hamper itself when you take the items out. Is there any excess moisture that needs removing with a cloth? If it’s fabric, does it need a run through the machine also? Take a look, because if there is moisture build up, soilage or mould within the hamper, that could be getting into your clothes and spreading through your home.

During and after the machine wash

Always use the right laundry detergent and the right temperature for each specific load. You want to make sure that each item has been fully cleaned to remove any organic matter which is food for mould.

Once your load is done, remove it from the machine as soon as you possibly can. Leaving wet washing in the machine leaves that musty smell, and keeps a nice moist environment for mould. Try and hang it or put it in the dryer as soon as you can.

Always make sure you leave your washer door open so that the machine can dry out completely before closing it. A lot of mould can build up in washing machines, this is one way to combat this. Running some white vinegar through an empty wash cycle is another good way to clean out your washing machine and reduce the risk of mould growth.

Within the clothes hamper

It’s important that you try to keep your laundry clean and well ventilated. Dryers should be ducted outside, and if this is not possible, a window or door needs to be open when the dryer is operating. Benches should be wiped down regularly to keep dust to a minimum, and the floor should be swept or vacuumed weekly.

The machines themselves need a good wipedown weekly and the filters emptied and cleaned out regularly. Always ensure that pipes and hosing are attached tightly and correctly to avoid any water leaks.

When it’s too late and the mould has taken hold

Sometimes it’s a little too late, and you may need a professional to come in and take a look at the situation. At Mould Pro we have years of experience with dealing with mould testing and mould remediation and we would love to help. Give us a call and have a chat with one of our friendly staff today.

What I have learnt from experiencing a mouldy house

mould_pro

Lucy Jones lived in your average older house in the suburbs of Brisbane with her husband and two kids. They had only just bought the house 3 months prior. Soon after moving in they started to notice the kind of sickness they had hardly felt before. “I would go through a box of tissues a day. My kids and I were constantly blowing our noses and coughing. We were all sleeping more than ever, and we just felt terrible. Luckily my husband Joe didn’t suffer as badly, he only thought he had a touch of hayfever.”

What Lucy didn’t know at the time, was that there was some major mould issues in their house. Here are Lucy’s recommendations below:

  1. If you smell any musty odors or visible signs of mould – never ignore it! (Mould in the shower is fine – Though you should really clean it!) If you are seeing mould in places you wouldn’t usually expect to find it, like in your wardrobe, on clothes, under the bed, on shoes or on the back of artworks hanging on the wall – Get it checked out! Inhaling mould spores is damaging to your health. Mould specialists can test these areas and more to work out what type of mould it is and where it is coming from.

     

  2. If you discover mould, don’t try to clean it yourself. It needs to be done in a certain way so that spores don’t spread, multiply and become inhaled by home occupants. Again, a mould expert needs to find the cause of the mould and where it’s coming from. Unfortunately Lucy’s house was on a sloping block and due to lack of drainage water was pooling underneath causing many moisture issues.

     

  3. When purchasing or renting a home, be careful of drainage issues. If purchasing, get a proper building inspection and ensure that they check the drainage. Lucy also discovered once the mould surveyors came in that the roof also had some leaking areas and some of the guttering needed replacing. These are also issues that will cause the growth of mould due to excess moisture getting through. If you’re renting and you start to notice mould or excess moisture issues, contact your landlord to have it inspected ASAP.

     

  4. You need to keep a home as well ventilated as possible. This could be just creating more airflow in the home by opening more windows and doors. Ducting clothes dryers to the outside of the laundry. Using your exhaust fan in the kitchens and extraction fans in the bathrooms. In some homes this is simply not enough and you need to look into a ventilation system. Check out https://www.zephyrventilation.net.au/ – We definitely recommend these guys for ventilation of your home.

     

  5. If you find you are suffering with upper respiratory health issues that are just not moving on, please have your home checked for mould. The mould and moisture could definitely be hidden. Perhaps it is behind a wall, or under the flooring. Living in the humid climate of QLD, where it frequently rains you never know when excess water can be trickling into hidden areas.

“For anyone who may have spotted mould in their house or is experiencing chronic health problems and just don’t know what to do about it or even where to begin I hope that this article is a good start.” Says Lucy. “I was just so thankful that someone recommended getting in touch with a mould expert, such as Mould Pro”.

Mould in your home after flooding

mould-pro-v2

Those who lived in Brisbane in 2011 know first-hand that we live in a crazy world. Mother nature can flex her muscles at any moment and send water where we never intended it to go. Since mould grows and thrives in a moisture rich environment, a flooded home is perfect. Mould is the last thing we want in our home. Not only does it look and smell terrible, but it is a health hazard to you and your family.

What can you do about it?

About the flooding? Not much sadly, except maybe live at the top of a hill, or an apartment building off the ground floor. But once your home has been flooded, there are things you can do to minimise the amount of mould that will grow:

  • Start hauling wet things, especially plush items like pillows, upholstered furniture, or curtains out of the house to a place like the garage or the driveway where they can dry.
    Use a shop vac or wet vac to suck water out of soggy carpets.
  • Fans can help get air moving in enclosed spaces, but be aware they may not be enough.
  • Consider renting or buying a dehumidifier to keep moisture levels low in the air in rooms you’re trying to dry. Basements and big areas may require larger, commercial-sized machines.
  • Remove baseboards and skirting boards from flooded walls.
  • Cut small openings along the bases of walls to let air into the wall to dry the back as well as the front.

How long have you got?

The faster you act, the more you can save. “You’ve really got 24 to 36 hours to work with,” says Rebecca Morley, executive director of the National Centre for Healthy Housing, a not for profit organization that wrote a guide to help residents clean up flooded homes after Hurricane Katrina. Mould is dangerous to those with asthma or pre-existing health problems, but high levels of mould are dangerous to otherwise healthy people.

DIY or call in the professionals?

If you choose to clean it up yourself don’t forget to use protection. A respirator – either a P95 or a P100 – will keep particles out of your lungs. Wear non-porous gloves, eye protection and coveralls to protect your clothing. Open windows and make sure the room is well ventilated. Do NOT mix bleach with other cleaning products to kill the mould. Mixing bleach and ammonia and other cleaning products will produce toxic fumes which are dangerous to you.

If more than one room of your house has been flood affected you should probably call in the professionals. They will bring in big fans and dehumidifiers to dry everything out. This needs to happen before you can even think of getting rid of the mould. No point wiping it off for it to grow back again! They will also be able to take care of testing and certifying how well they do the job, which the insurance company will want to see.

It is not uncommon for flooded properties to also have trouble with fire and smoke damage, from electrical fires that can occur from appliances and wiring getting wet. If this is the case with you then look at a company like www.disasterrestorations.com.au. They can take care of that and deal with the insurance company too.

What are the main causes of mould in your home?

mould pro

You’ve noticed that “musty” smell, and you are wondering – Is there mould in my home? And what has caused it?

Mould is a visual sign of excess moisture in your home and it grows due to various reasons. The most common cause of mould growth in your home is due to excess condensation, and many people do not realise just how much condensation can be created by normal everyday life in the home. Condensation is quite ok in your average house, but it should dry up fairly quickly or if it continues to lay stagnant mould could start to grow.

Mould is naturally part of our environment. Outdoors it breaks down dead organic matter such as leaves and dead trees. While outdoors mould can be a good thing, indoors it can cause havoc and should be avoided, not only does and it smell and look awful, it can cause nasty effects on our health. The way mould reproduces in your home is through the multiplication of tiny spores. The spores are so tiny that you are very unlikely to see them as they float through the air. Mould can begin growing in your home once these tiny spores land on moist surfaces. All mould need moisture to grow, therefore identifying any sources of condensation and abolishing them as quickly as possible should be a priority.

Building materials are great homes for mould growth. Excess moisture can be caused by incomplete drying of flooring materials, such as concrete, floor boards, carpet and so on. Flooding, whether it be by rising waters, flash flooding or any inside water accidents caused by faulty indoor plumbing can create a marvellous breeding ground for mould growth. Leaking roofs can also be a major contributor to mould. Moisture vapour passes through walls and ceilings and typically condenses over the cooler months with a longer heating season. As long as a surface is porous and moist, mould growth has the opportunity to occur. With the right conditions mold growth begins from 24 hours to 10 days.

Large mould growths require not only moisture but food sources – such as dust and cellulose. Housing materials such as plywood, drywall, carpet and underlay provide the perfect outlet for mould spores to source their nutrition. If a building experiences water damage mould is likely to grow within walls and lay dormant until humidity rises. If there is inadequate airflow with the building this is when the problem can really take hold. Nasty Mycotoxin levels are much higher in buildings that have had water damage, such as flooding or plumbing incidents. Even after the building has completely dried out, mould can still be an issue.

Mould can sometimes be hidden!

You can usually detect mould in your home by it’s smell and signs of water damage on walls or ceiling. But it can grow in places that you can’t generally see. It can be found behind wallpaper or wall paneling, on the inside of ceiling tiles, the back of drywall, or the underside of carpets or underlay. Plumbing pipes within walls may also be a source of mold, since they can sometimes leak causing moisture and condensation.
If you have found that your mould problems only occur during certain times of the year, your house is possibly lacking in airflow and ventilation. Mould problems occur in airtight homes more frequently in the hotter months when humidity is high inside the house, and moisture is trapped and unable to dry out. It can also occur in drafty buildings more frequently in the colder months when the warm air escapes from the living area and causes condensation.

What to do if you suspect a mould problem?

Get in an expert. You need to get the mould assessed to see what type it is and the best way to treat it before it spreads further and puts your family’s health at risk. Sometimes if the mould is hidden, like in the roof cavity on within walls you will have no idea where exactly to locate the main source or how to treat it correctly without further damaging areas of your home. Intrusive observation is sometimes needed to assess the mould level. This can include moving furniture, lifting or even removing carpets, checking behind wallpaper or paneling, checking ventilation ductwork and exposing wall cavities. Heavy mould growth will require professional mould remediation to remove and replace the affected building materials and eliminate the source of excess moisture. The aims of professional remediation are to treat or worst case remove contaminated materials and preventing further spores from entering a non-contaminated area. At Mould Pro we are experts in mould testing, assessment, treatment and removal. We can guide you through what you need to know to work through the process. Give us a call and one of our experienced team will be happy to assist you today.

Mould-proofing your Home for the Wet Season

It’s springtime. Therefore there is a lot of storms and rainy days, all the while humidity is also usually at it’s highest. This is prime conditions for mould spores to spread their wings and multiply. Mould is not only unsightly and smells awful, it also has negative impacts on our health and wellbeing.

So how can we go about mould-proofing our home for the wet season?

Identify any potential problematic ‘zones’

Do you notice any condensation on your windows or blinds in the morning when you get up? Do you wipe it down to dry it? Blinds, curtains and shutters are often hotspots for mould growth as that is where a lot of night time condensation gathers.

Have you noticed any overhead dripping pipes outside? Sometimes these dripping pipes can cause issues with moisture build-up that can go on to cause ‘rising damp’ that can go unnoticed until it is a big problem. It is best to check the reason why these pipes are dripping, and lead them away from your building and to a drainage area.

What about your laundry? Is the dryer correctly connected to an outdoor vent? Or are you drying your clothes is a hot steamy laundry that is the perfect breeding ground for mould growth. How are the extraction fans in your bathrooms? Are they strong enough to remove steam and condensation from your bathrooms?

Are there any drainage problems you have noticed around your property after heavy downpours? Water pooling in areas up against your building is not a good sign.

Any and all of these can lead to damp and, ultimately, mould. Take care to address such issues with effective moisture control at your earliest convenience.

Good Ventilation in your property can be the key

When cooking always use your range hood fan so that the steam escapes. Have your clothes dryer connected to an outdoor vent so that the moisture escapes outside rather than steaming up your laundry. If you are unable to do this, open up a window, or add a screen door to your laundry for ventilation. When you can, open up your bathroom windows after showers so that the bathroom can completely dry out.

Airing out bedrooms in the mornings is also a great move to stave off damp and combat mould growth.

Clean and inspect your roof gutters

Always clean out your gutters regularly, and if you are unable to do this yourself, have a professional do it for you. During your clean out you can see if there are any cracked and damaged guttering that may need replacing. Having a professional do this at the time can also mean they may be able to repair or replace cracked or damaged guttering at the same time as the cleaning is being done. Cracked and damaged roof gutters can allow moisture to seep through to areas where it shouldn’t be, allowing the build up of damp and eventually mould.

Keeping your roof gutters cleaned, and in good condition on a regular basis is one of the most effective moisture control techniques. Not only does it help with moisture in your roof cavity, but also leaking gutters can cause damp build up in areas of your property that would not normally happen if gutters were maintained correctly.

Have your roof inspected on a regular basis

Having your roof professionally inspected on a regular basis will ensure that any potential leak hazards can be found and rectified. It could be anything from cracked and damaged tiles to old or incorrectly installed skylights that can lead to roof leaks. Having a regular inspection will allow the professional to discover any potential leaks that can be repaired so as to prevent any future risk of damp and mould growth.

Roof tiles can break easily when they’re stepped on, so it’s important to take care if accessing your roof. Tiles can also become broken or cracked by branches dropping onto them, and even from children throwing items onto the roof, such as heavy balls and cricket bats. Skylights can also problematic for leaks. It’s possible for installation to be performed incorrectly, leaving gaps where water can get through. They can also become cracked and damaged by hailstones and branches. The usual wear and tear is also a factor, with older skylights developing more leaks.

For roofs that are constructed from a metal material such as steel or tin, it’s important to watch for the signs of rusting, as severe rust can lead to holes developing. Identifying rust early and taking steps to repair any damage can help prevent any extensive problems leading to leakage. Chimneys are another common cause of roof leaks, with inadequately waterproofed chimneys often being the complication.
