Mold takes hold easily in San Francisco homes, where coastal fog and older housing keep indoor air on the damp side. If you've spotted dark patches on a bathroom wall or caught a musty smell in the basement, this page is a good place to start. Below you'll find local mold remediation companies serving San Francisco and the wider Bay Area, so you can compare providers and reach out to one that fits your situation.
Look for a company that inspects and tests before it gives you a price, and that explains where the moisture is actually coming from. A good remediator treats the source rather than just the surface, so the problem doesn't come back after the walls are patched. It helps to ask how they'll contain the work area, protect the rest of your home, and whether they handle repairs afterward or leave that to you.
Browse the listings, see how each provider is rated by other San Francisco customers, and request a visit from one that answers your questions clearly.

Frequently asked questions
How much does mold remediation cost in San Francisco?
There's no flat rate. The price depends on how much area is affected, where the mold is, and what's driving the moisture behind it. A small bathroom patch is a very different job from mold spreading through a crawl space or behind drywall. Most San Francisco companies inspect first and give you a written quote after they've seen the extent of the problem, so it's worth getting more than one estimate.
How do I choose a mold remediation company?
Start with providers who inspect and test before quoting, and who explain their findings in plain terms. Ask whether they identify and fix the moisture source, how they contain the area during the work, and what they do to confirm the mold is gone afterward. Reading how other San Francisco customers rate a company on Google Maps can help you shortlist a few worth calling.
When is mold an emergency?
Mold itself usually isn't a same-day emergency, but the water problem behind it can be. If you've had a burst pipe, flooding, or a leak that soaked walls or flooring, act quickly, because mold can begin growing soon after materials stay wet. Anyone with asthma or a weakened immune system should treat visible mold seriously and have it looked at sooner rather than later.
Can I remove mold myself, or do I need a professional?
A small patch on a hard surface, like a bit of mildew on bathroom tile, is often something a homeowner can clean. Larger areas, mold on porous materials such as drywall or insulation, or anything tied to an ongoing leak are worth leaving to a professional. Pros contain the area so spores don't spread through the house, and they can track down the moisture source you might miss.
Is black mold in my home dangerous?
Any mold growing indoors is worth addressing, and the dark mold people call 'black mold' is no exception. It can affect indoor air quality and bother people with allergies or breathing conditions. Rather than trying to identify the type yourself, it's more useful to have a San Francisco remediation company inspect it, find the moisture feeding it, and remove it safely.
