Do you have a damp subfloor?

Sometimes you will find your subfloor is damp and mould and mildew and other nasties are growing there.  If you have dampness in your subfloor this can have some impact inside your home, but is not always the main cause.

As a general rule we tend to treat the subfloor of your home as a separate issue from the inside of your home and work on both as individual problems.

Dampness in your subfloor, though is really not a lot different than dampness inside your home, one of the main causes is lack of adequate ventilation and of course, lack of sunshine.

In your subfloor you can’t do much about the sunshine issue but we can work with the ventilation problems.

The first thing we suggest you can do is check to see if you have in fact got any air vents to let air in.  If you haven’t we suggest you start by maybe installing a few. Pretty simple, but hey, this could solve your problems.

Most homes have these vents installed when being built, but often they are covered by plants, shrubs and even footpaths being built too high and blocking air flow.

Clear shrubs and plants and realign or lower your foot path if need be. What you are trying to do, is let some air in and give your subfloor a chance to dry.

Another easy and practical way to achieve air flow is to open the subfloor access door or even replace it with a mesh door that allows air to flow under your home.

If after you have cleared your subfloor vents and they are pulling air in and under your home, as they should be, and your subfloor is still damp, we suggest the next step to take is installing some form of powered ventilation.

Our ducted inline extraction system is custom designed for each application.  Our team of technicians will professionally install, usually within a day and most homes will begin to feel the benefits immediately.


We recommend the system be allowed to run continuously for a month or two, then a timer can be fitted.  Most customers run the system during the day, and then program it to turn off automatically at night.

However, if your subfloor is particularly damp, run the system continuously for up to three months to allow your home to fully dry, and then fit a simple timer to automatically turn off at night.
