Common Questions

What services does Bay Mold offer for homes and businesses in San Francisco?

Bay Mold provides a full range of mold-related services including mold testing, inspection, remediation, weatherization, ERMI testing, and hidden moisture detection. We also handle damage restoration and environmental abatement. Whether you suspect mold behind walls, under sinks, or in crawl spaces, we can identify the source and recommend the appropriate solution.

How does Bay Mold address water damage from storm water intrusion or sprinkler system leaks in San Francisco?

Storm water intrusion and sprinkler system leaks are common issues in the Bay Area, especially during the rainy season. Bay Mold starts with a thorough inspection using hidden moisture detection tools to locate all affected areas. We then test for mold and recommend remediation steps, which may include drying, removal of contaminated materials, and sealing entry points. Our goal is to prevent recurrence by addressing the moisture source.

Can Bay Mold help with mold issues in apartment buildings or multi-dwelling complexes?

Yes, Bay Mold has extensive experience with multi-dwelling complexes, thanks to Graham’s background in building maintenance for such properties. We understand the importance of quick, contained remediation to minimize disruption to tenants. Our services include testing common areas and individual units, as well as coordinating with property managers to address underlying moisture problems like crawl space moisture or roof leaks.
