It's sometimes necessary to drill small holes at the bottom of the wall in order to direct warm, dehumidified air behind a wall. Injecting air into the wall does three things:
1) It raises the air pressure which causes the water to evaporate at lower temperatures.
2) It adds heat to the air, which provides water the energy it needs to turn from a liquid into a vapor, and
3) It removes humidity from the air which allows water to move from the structure into the air.
Our goal is to always save as much of the structure as possible after a water damage.
