Water Extraction in Larkspur done right means extracting every drop — the visible and the hidden — and transitioning immediately to a calculated drying program before the 24-48 hour mold clock expires.
Removes water faster than any portable unit.
Maps hidden saturation before drying begins.
Pinpoint and pin-type meters used to document exact moisture levels at each sensor point.
For deep standing water in Larkspur basements and crawlspaces before truck-mount transition.
The gap between a good extraction and a mediocre one isn't visible until weeks later — when mold shows up behind a wall that felt dry after a shop-vac cleanup. Here's what makes COS Water Damage Restoration's Larkspur extraction service different.
Every Larkspur job gets truck-mounted extraction rated for high-volume output, thermal imaging cameras that reveal sub-surface saturation, and moisture meters that document conditions at every sensor point. Consumer rental equipment doesn't come close.
The faster extraction begins, the smaller the final damage scope. Speed is built into our Larkspur operation.
Science-based extraction and drying produces better outcomes than intuition-based approaches.
On arrival in Larkspur, our crew assesses, prepares a written Xactimate-based estimate, and reviews it with you before a single piece of equipment is operated. The approved number is the invoiced number.
The right extraction approach depends on the water volume, source category, affected materials, and property type. Here's how we handle each scenario in Larkspur.
For large-scale events in Larkspur, the right equipment makes the difference between hours and days of extraction time.
Leaving hidden moisture behind after extraction is how Larkspur properties develop mold three weeks after a "completed" job by another company.
Hardwood floor salvage is a specialty — not every water extraction crew in Larkspur has the training or equipment to do it right.
Below-grade water extraction in Larkspur requires submersible pump capability for standing water, then portable extractor transition for residual moisture, and finally vapor barrier inspection and replacement to prevent recurring moisture accumulation. Confined space protocols apply in crawlspaces with limited access — our Larkspur crew carries the right equipment for each below-grade scenario.
Carpet and pad systems hold water effectively — up to a gallon per square yard — and standard extraction passes often leave substantial moisture in the pad beneath. Our Larkspur crew uses weighted extraction tools that apply appropriate pressure during the extraction pass, then evaluates whether pad salvage or replacement is more cost-effective based on the category and saturation level of the water.
Commercial extraction documentation is prepared to adjuster-ready standard throughout the process.


Call +1-844-499-0972 any time and a live dispatcher answers immediately. Your situation is assessed in real time, the nearest Larkspur extraction crew is dispatched, and your estimated arrival time is confirmed before you hang up.
Larkspur local deployment means faster arrival than regional dispatch every time.
Thermal imaging and moisture mapping precede extraction — so the scope is fully known before equipment runs. A written estimate is reviewed with you and approved before work begins. No extraction happens without your sign-off on the scope and cost.
Extraction is thorough — surface water, sub-floor moisture, and cavity saturation are all addressed in sequence. Immediately after extraction, our crew stages dehumidifiers and air movers to begin the structural drying program before mold risk accumulates.



"I've dealt with water damage before and had a mediocre extraction company leave moisture behind that turned into a mold problem. When it happened again in my Larkspur home, I specifically asked what equipment the company used before booking. COS Water Damage Restoration mentioned their truck-mounted systems and that sold me. The difference in output versus my previous experience was obvious — they were pulling water at a rate I hadn't seen before. Moisture mapping after extraction showed everything was clear. The drying crew followed immediately. Zero mold issues six weeks later."
"As a property manager in Larkspur with several units, I need water extraction contractors who document everything to adjuster standards and can scale to a multi-unit event. COS Water Damage Restoration has handled two multi-unit extractions for me and both times the documentation was clean, the coordination was smooth, and the bill matched the estimate. That consistency is hard to find."
"We called COS Water Damage Restoration after another company did what I now know was an incomplete extraction of our Larkspur basement. When COS Water Damage Restoration arrived, their moisture mapping immediately showed saturation under the floor tiles that the first company's work had missed entirely. They extracted the residual moisture, replaced the vapor barrier in the crawlspace, and set up a proper drying program. The first company charged us and left a mold problem waiting to happen. COS Water Damage Restoration fixed it correctly."
