Water Extraction in Londonderry 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 Londonderry 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 Londonderry extraction service different.
The equipment we bring to your Londonderry 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 Londonderry operation.
WRT certification isn't a formality — it determines whether your drying plan is based on psychrometric science or guesswork. Every Londonderry 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.
The right extraction approach depends on the water volume, source category, affected materials, and property type. Here's how we handle each scenario in Londonderry.
Truck-mounted extraction systems — the most powerful commercial water removal equipment available — are deployed for high-volume flooding events in Londonderry: 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 Londonderry properties develop mold three weeks after a "completed" job by another company.
Hardwood floor salvage is a specialty — not every water extraction crew in Londonderry has the training or equipment to do it right.
Crawlspace water left in place creates lasting structural moisture problems and serves as a primary mold incubation environment.
Carpet may be salvageable when extracted quickly; pad is typically replaced regardless. Our Londonderry team makes this determination honestly, based on the data.
Commercial extraction documentation is prepared to adjuster-ready standard throughout the process.


Call +1-844-499-0972 any time and a live dispatcher answers immediately. Your situation is assessed in real time, the nearest Londonderry extraction crew is dispatched, and your estimated arrival time is confirmed before you hang up.
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.



"The thermal imaging step was what impressed me most. Our Londonderry 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."
"As a property manager in Londonderry 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."
"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."
