Fixing Sub Floor Moisture Damage
The process to Fix sub floor moisture damage is a tedious process that first starts by drying the wood. This is done by removing the moisture from the air and usually involves heat to absorb the moisture. Wood is like a sponge or hygroscopic. This creates a problem when one resides in a relative humidity climate like we have in New Orleans or one has encountered flooding. What this means for the homeowner is your exposed sub floor will take on moisture from the environment and not have a chance to dry out. This makes it ripe for mold growth as well as termites who thrive in damp wood. Therefore, fixing sub floor moisture damage must be taken as a series of steps.
What to do when you have sub floor moisture. In some cases air flow can assist in the drying process. In high moisture content, heat may need to be used to dry the wood. However, once the wood is dry, it will take on moisture again if preventative measures are not taken. The under floor needs to be treated for mold growth. Then a sealant needs to be applied to prevent further moisture from penetrating the wood again. Fema recommends closed cell spray foam insulation as a preventative measure. Closed cell spray foam not only seals, it has the added benefit of keeping your interior floors from drafts.
