Sub Floor Ventilation
Mould lives in dark moist environments with no air flow. Sub floor ventilation systems are great to combat this situation. By extracting air from a subfloor crawl space we are actually stopping that moist, damp, mouldy air from pushing up into your home. The extraction process is actually pulling fresh air from outside in through the vents on the walls of your subfloor. The airflow being created then promotes drying. We design our systems on a case by case situation but the aim is to achieve cross ventilation through every part of the sub floor area.
