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 Dunbarton 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.
Maps hidden saturation before drying begins.
Daily readings tracked until drying targets are met.

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 Dunbarton extraction service different.
The equipment we bring to your Dunbarton property is the same tier used by commercial disaster recovery operations.
Our Dunbarton 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 Dunbarton technician we deploy carries active WRT certification and applies calibrated, documented methods.
On arrival in Dunbarton, 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 Dunbarton.
For large-scale events in Dunbarton, the right equipment makes the difference between hours and days of extraction time.
Extraction of visible standing water is only half the job. Thermal imaging cameras and calibrated moisture meters map where water has traveled beneath flooring, inside wall cavities, and above ceiling assemblies before extraction ends — so the drying plan addresses the complete scope of moisture, not just what was visible on arrival.
Original hardwood flooring in Dunbarton properties responds differently to water extraction than vinyl or tile — the drying window is narrower, the risk of cupping and buckling is higher, and the technique must account for the seasonal moisture content of the wood at the time of loss. Our Dunbarton technicians assess hardwood conditions during extraction and immediately plan for mat drying or board-by-board evaluation based on what the moisture meters show.
Below-grade water extraction in Dunbarton 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 Dunbarton 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 Dunbarton 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 Dunbarton 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.
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.



"The thermal imaging step was what impressed me most. Our Dunbarton property looked dry to me, but their camera showed moisture migration behind the baseboard on two walls I never would have suspected. If that had been left in place and the drying missed it, we'd have had mold within the month. Very glad they do this as standard procedure."
"Our hardwood floors in a Dunbarton 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."
"We called COS Water Damage Restoration after another company did what I now know was an incomplete extraction of our Dunbarton 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."
