Water Extraction in Derry 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.
High-volume truck-mounted extractors for large-scale flooding events in Derry.
Maps hidden saturation before drying begins.
Daily readings tracked until drying targets are met.
Handles water at depths portable extractors cannot.
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 Derry extraction service different.
Every Derry 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 Derry operation.
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.
The right extraction approach depends on the water volume, source category, affected materials, and property type. Here's how we handle each scenario in Derry.
For large-scale events in Derry, 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.
Hardwood floor salvage is a specialty — not every water extraction crew in Derry has the training or equipment to do it right.
Below-grade water extraction in Derry 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 Derry crew carries the right equipment for each below-grade scenario.
Carpet may be salvageable when extracted quickly; pad is typically replaced regardless. Our Derry team makes this determination honestly, based on the data.
Commercial extraction documentation is prepared to adjuster-ready standard throughout the process.


Live Derry 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.
Science-based scope assessment means the estimate is accurate, not a rough guess that changes after the fact.
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 Derry 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 Derry 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 Derry 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."
