San Francisco's marine layer keeps outdoor humidity high for much of the year while the city's pre-1940 housing stock was built with little to no vapor barrier. The result is chronic condensation in north-facing bedrooms, closet walls, and garden-level in-law units.
A review of accessible indoor and outdoor areas for visible conditions, water intrusion, and other signs that deserve attention.
Moisture-meter readings are taken where the inspector determines they will help evaluate the concern.
A swab or other surface sample may be collected when the inspector determines that laboratory identification would be useful.
Air samples may be considered only when observed conditions and the inspector's professional judgment support that method.
A written report built for real-world use: real estate transactions, insurance claims, landlord disputes, and physician referrals.
Two minutes on the form or the phone. Visible growth, a musty smell, a past leak, unexplained symptoms, or a pending home sale — all valid reasons to book an inspection.
A certified inspector evaluates accessible indoor and outdoor areas and documents the conditions present during the visit.
The inspector decides whether moisture readings or any sampling method is appropriate based on the observed conditions.
You receive documentation of the inspection and practical next steps. Laboratory findings are included only when a sample was collected and analyzed.
Typical San Francisco appointments are scheduled within Same-day and next-day appointments. Your inspector determines the appropriate scope after evaluating the property.
The same-day on-site mold assessment is $595 — $545 when ordered online, with the $50 discount applied automatically. The inspector determines the appropriate methods after evaluating the property. Any service outside the confirmed scope requires your approval.
In the Bay Area we routinely schedule within 24–48 hours, and we hold same-day slots for active leaks, flooding, and real estate contingency deadlines.
No—deliberately. We only inspect and test. We do not perform remediation, demolition, cleanup, or repairs, and we do not accept contractor referral fees. Because your findings cannot create repair revenue for us, our recommendation is based on the conditions we observe. If work is needed, you choose your own contractor.
Sampling is not automatic. When the inspector determines that a sample is appropriate and it is submitted, laboratory timing is estimated rather than guaranteed and may vary.
A retail kit does not include a professional evaluation of the property or help determine which method and location are appropriate. An inspector can first assess the conditions and decide whether any sampling would add useful information.
