Local Treatments in Daly City, CA

Local Context

Most Daly City Findings Sit in One Reachable Member, Not Throughout the Frame

Local treatment is a judgment about scope, not a budget version of fumigation. It works when a drywood colony is confined to wood we can reach and confirm — an eave rafter tail, a window header, a garage door header, a section of crawl-space framing. It fails when galleries run through framing a technician cannot open or reach, and in that case tenting is the correct answer and we say so plainly.

Daly City housing works in favor of local treatment more often than not. The 1940s-to-1960s tracts in Westlake and Serramonte are one- and two-story wood frame with open crawl spaces and simple roof framing, so the accessible members really are accessible. Damage also tends to begin where fog-driven moisture concentrates — the weather-facing wall, the joist ends over the downhill side of the crawl space, and the fascia and rafter tails that stay damp on the ocean-facing blocks in St. Francis Heights and along Skyline Boulevard.

Borate does double duty in this climate. Applied to bare accessible framing in a crawl space or attic, it treats what is present and leaves the wood unattractive to drywood termites and wood-decay fungi afterward — worth something where humidity keeps framing damp year-round. What it does not do is reach a subterranean colony living in the soil. If mud tubes are coming up from the ground, the work moves to the soil and the moisture, not the board.
