Standing water in your Mill Valley property is a race you're losing every minute. Our truck-mounted water removal systems extract thousands of gallons per hour — and our Mill Valley crew can be at your door in under 60 minutes, any hour, any day.
The right water removal team in Mill Valley 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.
Local crews and pre-staged equipment mean our Mill Valley Emergency Water Removal team arrives faster than regional contractors every time. We target 60 minutes from your call to boots on the floor.
Clean supply line failures, Category 2 gray water overflows, and Category 3 sewage-contaminated events each require different extraction methods and PPE. Our Mill Valley team is trained and equipped for every classification.
Emergency doesn't mean blank check. Before extraction begins, our Mill Valley team provides a written, Xactimate-based scope and cost estimate for your review and approval. The number you approve is the invoice you receive.
From the moment we arrive, our Mill Valley crew builds the documentation your carrier needs: pre-extraction photos, water category determination, volume estimates, and equipment deployment records. A complete file from the start means a faster claim.
COS Water Damage Restoration's Emergency Water Removal in Mill Valley 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 Mill Valley 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.
Pipe failures in Mill Valley properties — whether from freeze-thaw cycles, corrosion, or pressure failure — release clean or lightly contaminated water rapidly into wall assemblies and floor cavities. Our Mill Valley crews arrive with injection drying adapters specifically for pipe-failure scenarios where water has traveled behind drywall before it reached the floor.
Basement and crawlspace flooding in Mill Valley requires submersible and portable extraction systems capable of working in low-clearance and confined environments. Our crews carry the right equipment for each scenario — including high-capacity submersible pumps for deep standing water and portable extractors for post-pump residual water in below-grade spaces.
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 Mill Valley 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.


Every call connects to a real person who starts your Mill Valley response before you hang up.
Local crew, local knowledge, and fast roads — your Mill Valley 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 Mill Valley 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."
"My Mill Valley rental had a Category 3 sewage backup and I honestly didn't know who to call. COS Water Damage Restoration handled the entire thing — proper containment, professional extraction with the right equipment for contaminated water, and antimicrobial treatment before they left. My tenants were back in within the timeline they promised. Transparent, professional, and they charged exactly what they quoted."
"What I appreciated most was the written estimate before anything started. Water emergencies make you feel like you're at someone's mercy — the upfront pricing from COS Water Damage Restoration took that feeling away completely. The Mill Valley crew showed up fast, quoted fair, worked efficiently, and had every drop of water out of my laundry room, hallway, and two adjacent rooms before they staged drying equipment and left for the night."
