Termite-Damaged Wood

Termite damage in wood joist in crawl space

Wood that’s been damaged by termites tends to be hollowed out along the grain and may look completely undamaged. Inside, you can find ragged-looking “galleries” (tunnels in the wood) that are lined with dried mud, waste, and soil.

Other signs mud-lined “tubes” in visible areas around wood, and the sound made by knocking on termite-damaged wood: which produces a hollow sound. Damage in plaster and drywall may appear as tiny, dirt-lined holes.

Each year, roughly one in 30 homes are infested by termites and this can mean extensive damage to girders and joists.
