Stop dampness in its tracks! Reverse the cycle of mould and heat build up as you protect your health and your home.
How does fan-forced sub-floor ventilation contributes to you and your family’s health?
Moisture and evaporation is a part of earth’s cycle where the wind disperses it. As dwellings are built on the ground this locks in humidity and is entrapped in the sub-floor whereby moisture can go nowhere except into your home. Sub-terranean moisture from rain and stormwater run-off finds its way into the sub-floor area as higher evaporation rates and storms are more frequent during the summer periods. The use of natural ventilation should facilitate aeration in the sub-floor, however wind through passive vents is not always forthcoming which is very inconsistent. Another fact is that in the city, dwellings are in close proximity to each other which inhibits natural ventilation
When humidity in the sub-floor become elevated and mix with organic substances such as mycelium or fungus it creates a pungent odour which will penetrate into the habitable area, this allows for mould growth if left unchecked. Once this cycle starts, you put yourself and your family at risk of allergic reactions, infections or toxic responses. Symptoms include eye irritation, respiratory problems (such as wheezing, coughing or difficulty breathing), skin irritation, headaches, fatigue, aching joints, vomiting, nose or throat irritation and nasal or sinus congestion. If your condition is pre-existing, such as bronchitis and asthma, this will only make the condition worse.

A damp sub-floor can also affect the building by changing the cell structure in timber. Damp and humidity will make timber expand which will make floors bounce, leading to bending, warping and ultimately dry rot whereby the floor and its supporting structures fail. Solving a termite infestation or replacing supporting materials in your home can be a very inconvenient and costly exercise.
