Not all water extraction is the same. Consumer-grade shop vacuums pull surface water while saturation continues working into subfloor and wall assemblies. COS Water Damage Restoration's Altadena Water Extraction service deploys truck-mounted commercial systems rated for high-volume output — combined with thermal imaging and moisture metering that maps where the water you can't see has traveled.
Removes water faster than any portable unit.
FLIR thermal cameras reveal moisture in walls and under floors invisible to the naked eye.
Pinpoint and pin-type meters used to document exact moisture levels at each sensor point.
For deep standing water in Altadena 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 Altadena extraction service different.
The equipment we bring to your Altadena property is the same tier used by commercial disaster recovery operations.
Our Altadena crews are positioned locally — not dispatched from a regional hub. We target 60 minutes on-site from your call, with equipment staged during transit so we're working within minutes of arrival.
Science-based extraction and drying produces better outcomes than intuition-based approaches.
No estimates given over the phone without seeing the scope. No surprises after the work is done.
COS Water Damage Restoration's Altadena Water Extraction team handles every water extraction scenario — from residential flooding to large commercial events — with equipment and technique matched to the specific situation.
For large-scale events in Altadena, the right equipment makes the difference between hours and days of extraction time.
Leaving hidden moisture behind after extraction is how Altadena properties develop mold three weeks after a "completed" job by another company.
Hardwood floor salvage is a specialty — not every water extraction crew in Altadena has the training or equipment to do it right.
Below-grade water extraction in Altadena 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 Altadena crew carries the right equipment for each below-grade scenario.
Carpet may be salvageable when extracted quickly; pad is typically replaced regardless. Our Altadena team makes this determination honestly, based on the data.
Commercial and multi-family properties in Altadena present extraction challenges that residential scenarios don't: larger square footage, multiple affected units, infrastructure protection requirements, and business interruption cost. Our Altadena commercial extraction team scales crew and equipment to match the loss — deploying multiple extraction units and coordinating logistics across floors and units with a single dedicated project manager tracking the full scope.


Live Altadena dispatch — no voicemail, no hold queue, no automated menu.
Altadena 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.
We don't leave after extraction — we stay to set up drying so the project transitions without delay.



"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 Altadena 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 Altadena 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 Altadena 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."
