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 Chehalis 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.
High-volume truck-mounted extractors for large-scale flooding events in Chehalis.
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 Chehalis basements and crawlspaces before truck-mount transition.
Four commitments that define every Water Extraction job COS Water Damage Restoration performs in Chehalis.
The equipment we bring to your Chehalis property is the same tier used by commercial disaster recovery operations.
Our Chehalis 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.
WRT certification isn't a formality — it determines whether your drying plan is based on psychrometric science or guesswork. Every Chehalis technician we deploy carries active WRT certification and applies calibrated, documented methods.
On arrival in Chehalis, 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 Chehalis.
For large-scale events in Chehalis, the right equipment makes the difference between hours and days of extraction time.
Leaving hidden moisture behind after extraction is how Chehalis properties develop mold three weeks after a "completed" job by another company.
Hardwood floor salvage is a specialty — not every water extraction crew in Chehalis has the training or equipment to do it right.
Below-grade water extraction in Chehalis 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 Chehalis 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 Chehalis 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.


Live Chehalis dispatch — no voicemail, no hold queue, no automated menu.
Our crew arrives with truck-mounted and portable extraction equipment configured for your reported scenario. Equipment is staged during transit so the crew is productive immediately on arrival — not spending 20 minutes unloading and setting up in your driveway.
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 Chehalis 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."
"Our hardwood floors in a Chehalis craftsman home were at risk after the flooding. The COS Water Damage Restoration crew's extraction specialist assessed the moisture content in the boards during extraction and confirmed they were within the drying window for mat drying. We saved the floors — the difference in cost versus replacement was significant. The specialist explained the whole process and called with readings every morning."
"The written estimate before extraction was a first for me — every other contractor I've used has just started working and handed me a bill. COS Water Damage Restoration's pricing conversation happens before the equipment turns on. That's the right way to do it and I won't use anyone who doesn't operate this way."
