Dry and rotting wood

Dry Rot in Metro Atlanta and surrounding areas

Ironically, the cause of dry rot damage is actually an excess of moisture that makes contact with wood. Dry rot is a condition where fungus slowly breaks down wood fibers, which makes the wood brittle and look aged. When touched, this rotted wood feels dry, so hence the name dry rot was coined.

Types of Dry Rot

White Rot - targets hardwood. Look out for white or yellowish discoloration. When touched, the wood will feel spongy, and will have a stringy appearance.

Brown Rot - targets softwood, causes wood to turn a dark brown. Often called "brown cubical rot" as the wood can have the appearance of a checkerboard, because of the way the wood splits across the grain. This type of rot causes wood to become dry and powdery, which is where "dry rot" comes from.

Mistaken Identity

While dry rot can sometimes look like mold on the surface, or damage done by termites or carpenter ants, there are distinct differences between dry rot and other causes of wood damage.

Mold is a kind of fungi that grows on the surface of wood. Mold doesn't break down and weaken wood the way dry rot does.

Meanwhile, the damage done by carpenter ants is evident when wood is being chewed through, and they leave behind tiny piles of sawdust in their wake. You can also spot clean cavities, and this is where they live.

Termite damage is very similar to dry rot, but the wood is wetter and termite galleries will be present.

Preventing Dry Rot

An important thing to note is that to prevent dry rot damage, you need to reduce or wholly eliminate the excess moisture. It isn’t as simple as getting a leaky pipe fixed, nor is it as complicated as stopping water infiltration through your basement foundation. One of the most common signs of dry rot and termite damage happens when wood comes into contact with soil, as it happens with a failed foundation.

Drainage and gutters will help to lower the water level around your home. Keeping rain water away from your foundation with proper grading, and cleaning gutters to prevent water from making its way underneath your house and building up there will help prevent dry rot.

  • If there's any untreated wood around, it should be 18 inches or more from the ground.
  • Make sure that you get vapor barriers installed on your basement walls and encapsulate your entire crawl space.
  • Make sure that you use dehumidifiers in all basements and crawl spaces, as condensation will cause relative humidity to rise above 50%.
  • Repair plumbing leaks, fix roof leaks and regularly clear debris from the rain gutters.
