Sub floor ventilation from Doctor Damp
Frequently a building inspector or pest inspector notifies clients
when there is a situation with dampness or poor ventilation that is affecting the
health of the home. Even though the home may be elevated it needs air circulating
underneath it to keep it dry.
Dr Damp approaches a subfloor situation with a three-pronged approach. Firstly, we
remove the damp air from the underfloor, secondly we force fresh air into the space
to replace it, and finally (the most critical step) we create an air circulation
pattern that has a drying effect. This is calculated based on air volume, so the
correct amount of circulation occurs using low cost fans.
Grates have sometimes been installed in some homes that we visit, unfortunately this
often does not solve the problem. In one home, grates had been placed at intervals
of approx 1 metre apart, but did not improve the airflow sufficiently - this is
generally the case.
This is where the mechanical system of Dr Damp comes into it's own.
By elimination of a damp subfloor situations such as dry rot and termites you don't
have the conditions they need to flourish. When the cost of treating termite infestation
is considered, with about $3 - 4000 to treat an average termite infestation, let alone
replacing timber and gyprock, it makes keeping your house ventilated a cost-effective
investment.
In our experience in the last 10 years we have not seen termite infestation in any
correctly ventilated sub floor area.
