Sub-Floor Ventilation

Mould will often grow in dark, humid environments that receive very little air flow, such as the sub floor area under a house. Sub Floor Ventilation systems are often used to help prevent mould from growing in these dark, damp spaces. They work by removing the humid air from the sub floor area under your home and pushing it outside, rather than up into your home. During this process, the vents in the walls of your sub floor will also suck in fresh air from outside, circulating it under your home to promote drying of damp structures. Each house is very different, therefore we design each of our systems to fit your unique situation and achieve the ultimate goal of cross ventilation through every part of your sub floor.

Ventilation is one part of the removal process, check out our Mould Removal page to learn about the rest.
