Mold Inspection in San Francisco: local factors
About 77% of the city's homes date from before 1980 (Census ACS). Victorians, Edwardians, and the stucco rows of the Sunset each have their own weak points, and in a city where fog alone can wet a wall, finding the true cause is most of the work.
Condensation or a leak?
Condensation leaves a pattern: spots across cold surfaces, worst near windows and in corners, often on the side facing the ocean. A leak leaves a zone that tracks back to a source. The inspector reads humidity, maps wall temperatures with a thermal camera, and takes meter readings to tell which one you have, because the fixes are completely different.
Bay windows and siding
Bay windows on Victorian and Edwardian fronts collect water at the sill and the joints below. The inspector checks the framing under the window, the trim, and the siding seams on the weather side, where storms drive rain in.
Stacked units
In flats, condos, and TIC buildings, a shower, a toilet, or a kitchen line in the unit above can wet your ceiling or wall for months. Readings on both sides, where access allows, show where the water starts, which helps when you take it to the neighbor or the HOA.
When to book
- A smell in a bedroom or closet with no visible spots; see what a musty smell means.
- A stain on the ceiling below another unit's bathroom.
- Before buying a Victorian, Edwardian, or ground-floor unit.
- Spots that keep coming back on the same wall every summer.
Choosing an inspector
California licenses neither home inspectors nor mold inspectors, so ask for training such as ACAC or IICRC certification, insurance, and a sample report, and find out whether the firm also does removal. An independent report carries more weight with a neighbor, an HOA, or an insurer.
Cost
Angi's national data puts a mold inspection at about $300 to $1,000. Multi-unit access, a large Victorian, or lab samples push it higher. For lab work alone, see mold testing in San Francisco; for the cleanup, mold remediation in San Francisco.
Booking
Describe the building, the floor you are on, and where the problem shows. The company on the line quotes the visit, and the call is free.
