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.
Removes water faster than any portable unit.
Maps hidden saturation before drying begins.
Daily readings tracked until drying targets are met.
For deep standing water in Derry basements and crawlspaces before truck-mount transition.
Four commitments that define every Water Extraction job COS Water Damage Restoration performs in Derry.
The equipment we bring to your Derry property is the same tier used by commercial disaster recovery operations.
The faster extraction begins, the smaller the final damage scope. Speed is built into our Derry operation.
WRT certification isn't a formality — it determines whether your drying plan is based on psychrometric science or guesswork. Every Derry technician we deploy carries active WRT certification and applies calibrated, documented methods.
No estimates given over the phone without seeing the scope. No surprises after the work is done.
COS Water Damage Restoration's Derry Water Extraction team handles every water extraction scenario — from residential flooding to large commercial events — with equipment and technique matched to the specific situation.
Truck-mounted extraction systems — the most powerful commercial water removal equipment available — are deployed for high-volume flooding events in Derry: storm flooding, major pipe failures, and large appliance failures that release significant water rapidly. Truck-mount output far exceeds portable units, reducing total extraction time and limiting saturation of structural assemblies.
Leaving hidden moisture behind after extraction is how Derry properties develop mold three weeks after a "completed" job by another company.
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 and multi-family properties in Derry present extraction challenges that residential scenarios don't: larger square footage, multiple affected units, infrastructure protection requirements, and business interruption cost. Our Derry 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 Derry dispatch — no voicemail, no hold queue, no automated menu.
Derry local deployment means faster arrival than regional dispatch every time.
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.



"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 Derry 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 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."
"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."
