What Is Dry Rot?
A certain species of fungus causes dry rot. Its spores land on wood, and with enough moisture it thrives, despite the name. You may see white or grey growth on the wood and even a mushroom-like body if advanced. Other visible signs of dry rot include blistering, cracked or peeling paint , wood darker than surrounding areas, and green algae on the wood.
Window and door sills are most often affected by dry rot, but it can grow into non-wood surfaces in contact with the ground. It also can spread to non-wood materials such as plaster and mortar.
Test for dry rot by inserting a screwdriver into the wood. If it goes in easily or feels spongy, you likely have dry rot.
Dry rot is the term used to describe rotten wood, specifically in the context of construction. This “wood rot” affects all wood members exposed to the elements, such as rain, sun and wind. A destructive fungus develops, damaging the wood, which leads to the condition that we know today as “dry rot”. These conditions develop due to continuous moisture exposure from rain, sprinklers, roof leaks, plumbing leaks or gutter/ downspout malfunction. Dry rot is found in many areas of a structure including: windows and doors, trims, siding, decks and patios, eaves and roofing members, framing and sub-framing. Poor house maintenance will expedite the rotting process, increasing future repair
