Dry Rot Repair

The San Francisco and Marin Country Earthquake Seismic Retrofitting and Dry Rot Repair experts


Repairing dry rot damage increases your home’s structural stability and (along with seismic retrofitting) helps fortify your house in the event of an earthquake. Dry rot repairs and maintenance can include a wide variety of tasks including proper caulking, painting, and siding and trim work maintenance. If your interior and/or exterior walls have dry rot damage, it is necessary to repair this issue so your home’s structural integrity will stand strong for many years to come.

This condition occurs when wood structures are damp or have wood-dirt contact and begin to deteriorate. As the moisture increases, harmful fungi attacks the wood, breaking it down and causing it to weaken and rot. The reason it is referred to as “dry rot” is because the wood appears to be dry. Most homes have some form of dry rot where paint or other flashing barriers have not been applied to areas exposed to weather.

  1. Every bit of wood that is damaged needs to be removed. We continue to remove dry rot until structurally integral wood is discovered.
  2. Using a wire brush, loosened material is removed from all surfaces of the infestation, including metal, masonry, and pipes. Resulting dust and debris is removed as well.
  3. Our two-part dry rot process prevents moisture from re-establishing itself.
  4. Substantially dry rot-damaged materials such as mud sills, floor joists, and floor beams in the crawl space area are rebuilt.
  5. Install a sump pump.

Preventing Dry Rot in a Basement: Remove all standing water sources, then install a plastic vapor barrier on the walls and floors. Install a self-draining dehumidifier powerful enough to dry the area (at least a 100-liter model).

Preventing Dry Rot in a Crawl Space: Ensure adequate cross-ventilation is circulating air. Encapsulate the crawl space with a crawl space liner. In some instances, you may need to install a sump pump.
