SUB FLOOR VENTILATION
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. First 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 environmentally friendly air pumps. Some homes that we visit have large vents installed which unfortunately doesn't always solve the problem. |

Sometimes we see that large vents get place at intervals of approx 1 meter apart, but don't improve the airflow sufficiently and, unfortunately, this is generally the case. This is where the mechanical systems of Doctor Damp comes into their own.By elimination of a damp subfloor (situations such as dry rot and termites) you don’t have the conditions termites can flourish. When the cost of treating termite infestation is considered, with about $4,000 - $6,000 to treat an average termite infestation (let alone replacing timber and gyprock!), it makes keeping your house ventilated a cost-effective investment. In all our experience in the past 10 years we have not seen termite infestation in any correctly ventilated sub floor area. Don’t be fooled, some of the dampest homes we have seen have an extremely dry sub floor ventilation space. If you were to touch the ground under the floor it would appear dry, however if you hold your hand on the ground for a minute you will actually feel the cold of damp running up your arm. In our experience in the last 10 years we have not
seen termite infestation in any correctly ventilated
sub floor area. |
