What is dry rot and how does it affect your home?

Rot is the leading cause of damage in wood structures in and around the Portland area. Dry rot, which is sometimes called “brown rot,” “wood rot,” and “wet rot,” is bad enough in and of itself, but can lead to even more issues like mold and mildew. This is because dry rot is actually a fungi which can grow with no obvious source of moisture. In fact, this strange fungi can actually be fed by moisture in the air! This makes dry rot difficult to spot prior to it spreading and near-impossible to predict. As it spreads, the fungi literally eats away at the wood leaving it dark and crumbly. At that point, you can even crush the wood into small chips or powder with your bare hand! Unfortunately, once dry rot begins spreading within a structure, it doesn’t stop.

Where can dry rot be found?

As dry rot can infiltrate your home via interior and exterior sources and infest any wood structure, it can be found virtually anywhere in the home. It’s more likely to take hold where moisture is likely to be present, but you can find it in posts, beams, kitchen and bathroom floors and walls, deck framing, deck boards, eaves, roofs, near damaged gutters, foundations, sill plates, window and door framing, siding, cripple walls and crawl spaces, among others. Spotting rot is not always easy, but there are some things you can look for.
