Many older homes throughout Sydney have been built with suspended timber-floors that ensure there are large spacious areas under their flooring.  This area beneath your house is an integral feature of your home and has a multitude of functions.

A key aspect here is the fact that it allows the building to breathe.  Without having the right cross flow ventilation what happens is your floor begins absorbing moisture coiming up from the soil below.  As if that’s not enough of an issue on it’s own it is then compounded by the fact that this will in turn then increase the homes internal humidity.  Timber joists and bearers also then absorb further moisure which leads to mould and wood decay.  This then creates the ideal situation to invite termite activity within your property.

The first thing you should do the begin the process of rectifying this problem is to have your sub floor ventilation checked a by a professional.  You need to make sure that water is not pooling or seeping into the subfloor areas of your home.  External drains should also be examined for breaks and any blockages that may have occured.  Exisiting vents are easily obstructed by soil, plants and shrubs so these also should be checked.  You may also need to clear mud, snails, spider webs and the like from the vents.
