When water damage hits your home or business in New London, you need a local crew that can actually show up fast — not a call center routing your emergency to a contractor two hours away. COS Water Damage Restoration's New London-based Water Damage Repair teams are licensed, certified, and ready around the clock.
Local New London crews on standby — not dispatched from out of the area.
Certified professionals, not unlicensed laborers.
Written estimate in your hands before any work begins.
We build your claim file and deal with your adjuster directly.
We've handled everything from flash-flood basement extractions in New London's older neighborhoods to multi-floor commercial water events in newer construction, and every job has reinforced the same core truth: speed and expertise make the difference between a manageable repair and a catastrophic rebuild.
Our New London crew lead coordinates directly with your insurance carrier from the moment we arrive on site — building the documentation package, scheduling the adjuster walkthrough, and following up on open claim items until your settlement is confirmed and you can move forward with reconstruction.
If you've already experienced water damage in New London and need someone to respond right now, call +1-844-499-0972 — our local crew is ready.

Every service listed below is available 24/7 in New London — no wait lists, no "call back during business hours," no sending you to a subcontractor we can't vouch for.
Our truck-mounted extraction systems can pull high volumes of water in a fraction of the time it would take with consumer-grade equipment — getting the visible water out fast while our moisture detection team maps the water you can't see yet. Call +1-844-499-0972 the moment you discover water in your New London property — our dispatcher will guide you through immediate protective steps while our crew is already on the way.
We approach every New London residential job with the understanding that we're working inside someone's home, and that means treating the space with care, communicating clearly about what we're doing and why, and keeping the disruption to your family's daily life as minimal as possible. Our moisture mapping process identifies every area where water has penetrated — not just what's visible on the surface, but the moisture inside wall assemblies, under flooring systems, and in ceiling cavities — so that the drying plan we build addresses the complete scope of moisture, not just the obvious puddles.
Water damage to a commercial property in New London isn't just a property issue — it's a business interruption event that starts costing revenue from the moment the damage begins. Our New London commercial team has experience with office buildings, multi-tenant retail spaces, restaurants and hospitality properties, warehouses and light industrial facilities, medical and professional offices, and multi-family residential properties.
Mold is the almost-inevitable consequence of water damage that wasn't addressed quickly or completely — and in New London's climate, wet building materials can support mold growth in as little as 24 to 48 hours after initial exposure. We never treat mold as a surface problem or attempt to cover it with encapsulants when removal is required — our remediation approach is based on assessment of the affected material and what the manufacturer and IICRC standards recommend for each scenario.
Building new drywall or flooring over materials that are still holding excess moisture leads to cracking, warping, fastener failure, paint peeling, and eventually mold growth — which is why our New London drying crews take measurement seriously and don't sign off on a project until the numbers confirm completion. Daily moisture readings are taken at consistent sensor points throughout the drying cycle and recorded in a written log that documents the progress of drying over time — useful for your insurance file and for your own records.
Our claim coordinators assigned to New London jobs prepare documentation packages that include every element a WI insurance adjuster needs to process a water damage claim efficiently: structured photo evidence, moisture data logs, equipment records, and a complete Xactimate scope of work that mirrors how your carrier's own systems calculate cost estimates. If your adjuster's initial settlement offer doesn't fully account for the documented scope of loss, we prepare and file a supplement with supporting evidence — a step that many homeowners don't know they can take and that frequently results in additional covered compensation.

Our Xactimate-based estimates are formatted the way your WI insurance carrier expects to receive them, which means no disputes and faster claim processing.
Your New London home or business deserves the professionalism that certification represents.

Supplement filing for underpaid claims is part of the service — because we believe your policy should pay what your loss is documented to be.
Five-star reviews are earned, not purchased — and they reflect what happens when every technician takes personal pride in the outcome of every job.

Here's exactly what happens when you call COS Water Damage Restoration for water damage in New London, from the moment the phone rings to the day we hand your property back.
You receive your crew's estimated arrival time before you hang up, and a direct callback number if anything changes en route.
Our crew arrives at your New London property and immediately begins a systematic assessment — identifying every water entry point, mapping moisture migration with detection instruments, and classifying the water category (clean, gray, or black water).
With the scope confirmed and your approval in hand, extraction begins immediately using the highest-capacity equipment appropriate for the situation.
Equipment stays until documented readings confirm completion — not until a certain number of days has passed.
A written remediation report is issued that documents every action taken and every clearance measurement recorded.
The final walkthrough is conducted with you personally, confirming satisfaction with every element before we close out the job and hand you your warranty documentation.
That local familiarity translates into faster arrival, fewer logistical delays, better-informed scope assessments, and the kind of personal accountability that comes from knowing your work might be reviewed by someone who lives down the street.
New London's mix of housing stock — from older historic homes to newer construction developments — presents a range of material and structural challenges that our crews encounter regularly.
Whether it's the spring flooding pattern, the summer storm profile, or the winter freeze-thaw cycle that affects New London's plumbing, we approach New London jobs with an awareness of local conditions that an out-of-area contractor simply can't replicate.
Water damage restoration costs in New London vary based on several factors: the volume of water, the category of water (clean vs. contaminated), the materials affected, the square footage involved, and the extent of mold risk.

Read what New London customers consistently say about response time, professionalism, pricing, and results.
"I run a small business in New London and had a toilet supply line failure on a Sunday night that flooded my office suite and spread into the common hallway. I called COS Water Damage Restoration, who answered immediately, and had a crew at the building in under an hour. They worked through the night to extract the water and set up drying equipment before we opened Monday morning. My employees came in to a building that was functional — inconvenient, but operational. The insurance claim was handled entirely by their coordinator and settled in less than three weeks. I recommend them to every business owner I know in New London."
"After storm water came through our basement window well during a major rain event, I was at a loss. I had an inch of standing water across the whole basement and no idea who to call. A neighbor recommended COS Water Damage Restoration and I'm glad she did. The crew arrived quickly, immediately identified that the water had already gotten under the vinyl plank flooring, and explained everything they were going to do before they started. The drying took a week — they checked in every single day — and when it was done the insurance settled the claim at the full documented amount. I've since recommended COS Water Damage Restoration to three other people in New London."
"Mold found during the renovation of our New London home led us to COS Water Damage Restoration for remediation. The discovery was stressful — we didn't know how extensive it was or what it meant for the timeline of our project. The COS Water Damage Restoration team came in, assessed it thoroughly, explained exactly what they found and what the IICRC-compliant remediation process looked like, and completed the job on time. The post-remediation air testing came back clear, the report they provided satisfied our contractor and our insurer, and we were back on schedule within a week. Professional from beginning to end."
