Perhaps you are wondering what areas of a house are more vulnerable to wood decay. Its good to consider what it needs to thrive, moisture, oxygen and a food source. There are a lot of places in a home that can provide all these things, here is a list of a few of them:
Roof penetrations which have incorrect or damaged flashing.
Wood which comes into direct contact with concrete, soil or masonry.
Cracks in foundations
Insufficient grading which means that water cannot drain away from the foundation, and so creates pooling.
Ground floor decking or deck support posts.
Area surrounding corroded plumbing fixtures as well as sub flooring which surrounds toilets and tubs.
If they have not been correctly installed, you could see wood rot underneath sliding glass doors and windows.
Perhaps after seeing this list, you will be able to locate areas where wood rot might be a problem in your home. If you are unsure about detecting wood rot, why not consider a home inspection. This way, you will be able to either detect the problem or find out ways of preventing it.
