Standing water in your San Anselmo property is a race you're losing every minute. Our truck-mounted water removal systems extract thousands of gallons per hour — and our San Anselmo crew can be at your door in under 60 minutes, any hour, any day.
The right water removal team in San Anselmo gets to you fast, removes the water completely, and transitions immediately to structural protection — not a service that extracts visible water and leaves hidden moisture to fuel mold growth.
Your water removal response time is directly determined by where the crew is based. Ours is based in San Anselmo.
We don't turn jobs away based on contamination category. Our San Anselmo crew handles Cat 1 through Cat 3 with the proper protocols for each.
Emergency doesn't mean blank check. Before extraction begins, our San Anselmo team provides a written, Xactimate-based scope and cost estimate for your review and approval. The number you approve is the invoice you receive.
We document everything at the extraction phase — before conditions change and evidence is lost.
COS Water Damage Restoration's Emergency Water Removal in San Anselmo covers the full spectrum of water intrusion events — from minor appliance overflows to major storm flooding, and every source of water damage in between.
Flash flooding and severe storm events push large volumes of water into San Anselmo basements, crawlspaces, and ground-floor living areas in short timeframes. Our truck-mounted extraction systems — rated for high volumes — are deployed the moment we arrive, pulling standing water while our moisture crew maps migration into adjacent assemblies.
Fast extraction at the point of failure combined with cavity access drying limits the drywall and framing removal scope.
After extraction, crawlspace vapor barrier inspection and replacement prevents recurring moisture accumulation.
We never use standard extraction equipment on contaminated water events — cross-contamination risk is real, and proper equipment matters.
Dishwasher failures, washing machine overflows, refrigerator line leaks, and water heater ruptures in San Anselmo homes release water that travels quickly across hard surfaces and wicks under baseboards and into subfloor materials. Even small appliance events can saturate significant square footage if not caught and extracted within hours of the failure.
We produce the detailed commercial loss documentation that commercial insurance adjusters require.


Call +1-844-499-0972 and a live dispatcher answers immediately — no voicemail, no automated menu, no hold queue. Your dispatcher identifies the closest San Anselmo crew, confirms availability, and dispatches within the first few minutes of your call.
Local crew, local knowledge, and fast roads — your San Anselmo response is as fast as it can be.
No equipment gets placed without your written approval of the scope and cost.
Complete removal is the standard, not a best effort. We don't leave until the water is out.



"When our San Anselmo office flooded from a sprinkler malfunction, I needed someone who could handle commercial extraction and not leave us without power or a server room. COS Water Damage Restoration's crew coordinated around our IT setup, staged the extraction equipment without disrupting the networking infrastructure, and had us operational the next morning. One of the best responses I've seen from any service company."
"A sump pump failure let in about 4 inches of water across our entire finished basement in San Anselmo. I found it at 6 a.m. on a Monday. COS Water Damage Restoration was on site by 7:15, had the water out by 10, and the drying equipment running before I left for work. The moisture mapping showed water under our LVP flooring that would have become a mold problem if we hadn't caught it. Grateful for the thoroughness."
"Three different companies told me they could help with our San Anselmo storm flooding. Only COS Water Damage Restoration showed up with a truck-mounted extraction unit instead of a few shop vacs. The difference in output was enormous — they pulled the water out in a fraction of the time I expected. Highly recommend calling them first."
