Terms of the Trade: What Is Dry Rot? Terms of the Trade: What Is Dry Rot?

Dry rot is the decaying of wood caused by a fungus that eats away at its structural integrity. While moisture initially attracts the fungus, the actual process of decay requires very little, if not any, moisture to take place. You can identify dry rot by the wood's brittle, cumbly appearance with cubicle-like cracking over the surface. If left unchecked, dry rot can entirely collapse structures. To prevent dry rot, limit wood's exposure to moisture (e.g., seal wood siding and decks, ventilate bathrooms and kitchens, and check roofing annually for water damage or mold). Treatment for dry rot may involve copper compounds, commercial anti-freeze, or epoxy for renewed strength.
