The sub-floor area, also known as the sub-floor void, is the space between a ground floor and the substrate under it. If the underlying substrate is damp, the humidity within the sub-floor area can rise, causing condensation to form on the undersides of your floorboards, resulting in potentially costly and unsafe structural damage.

Thankfully, sub-floor condensation can be prevented by implementing simple ventilation methods, such as the installation of air bricks. These small openings allow for the circulation of air, effectively managing humidity levels and avoiding the buildup of moisture that leads to condensation.
