When water gets in, the damage clock starts immediately. COS Water Damage Restoration's Larkspur Emergency Water Removal crew carries professional-grade extraction systems to every job, arriving fast and working fast to limit the scope of what gets damaged.
The right water removal team in Larkspur 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 Larkspur.
We don't turn jobs away based on contamination category. Our Larkspur crew handles Cat 1 through Cat 3 with the proper protocols for each.
No surprise billing after the fact — your written estimate is your price, period.
We document everything at the extraction phase — before conditions change and evidence is lost.
Every Emergency Water Removal scenario requires the right equipment, the right technique, and the right team. Here's what we handle in Larkspur.
Flash flooding and severe storm events push large volumes of water into Larkspur 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 Larkspur properties — whether from freeze-thaw cycles, corrosion, or pressure failure — release clean or lightly contaminated water rapidly into wall assemblies and floor cavities. Our Larkspur 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 Larkspur 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.
Category 3 water — sewage overflows, sump pit backup, and groundwater intrusion — requires full PPE protocols, contained extraction, and regulated disposal procedures. Our Larkspur Emergency Water Removal team handles contaminated water events with the proper containment barriers, biohazard-rated extraction equipment, and antimicrobial pre-treatment before structural drying begins.
Dishwasher failures, washing machine overflows, refrigerator line leaks, and water heater ruptures in Larkspur 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.
Water events in Larkspur commercial properties carry additional complexity: larger square footages, infrastructure like server rooms and electrical panels, business interruption risk, and tenant notification requirements. Our commercial Emergency Water Removal team in Larkspur deploys at scale — multiple extraction units, larger crew sizes, after-hours scheduling to minimize disruption — and maintains a dedicated project manager for commercial loss communication.


Call +1-844-499-0972 and a live dispatcher answers immediately — no voicemail, no automated menu, no hold queue. Your dispatcher identifies the closest Larkspur crew, confirms availability, and dispatches within the first few minutes of your call.
Local crew, local knowledge, and fast roads — your Larkspur 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 Larkspur 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 Larkspur. 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."
"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 Larkspur 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."
