Positioned in Hampton for fast local response every time.
Certified professionals, not unlicensed laborers.
Written estimate in your hands before any work begins.
Works with all major NH insurers.
COS Water Damage Restoration's Hampton team isn't a remote dispatch forwarding your call to whoever happens to be available — we maintain a dedicated local operation in Hampton with crew members who live and work in the community, understand the local building stock, and know the fastest routes to your neighborhood at any hour.
Our Hampton 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.
COS Water Damage Restoration has earned the trust of Hampton homeowners, landlords, property managers, and commercial facility owners because we consistently do what we say we'll do: we arrive when we say we'll arrive, we provide the estimate we quoted, we complete the documentation we promised, and we stand behind the work with a written satisfaction guarantee.

Our integrated service model means Hampton property owners have one phone number, one point of contact, and one company responsible for the outcome from start to finish.
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. After extraction, we don't pack up and leave — we immediately stage the drying equipment that will begin drawing moisture from structural assemblies before mold has a chance to gain a foothold.
We approach every Hampton 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 Hampton isn't just a property issue — it's a business interruption event that starts costing revenue from the moment the damage begins. Commercial jobs in Hampton receive a dedicated project manager who handles all carrier communication, adjuster scheduling, supplement filing, and daily progress reporting — leaving business owners and property managers free to focus on their operations rather than managing a restoration project.
COS Water Damage Restoration's mold remediation team in Hampton follows IICRC S520 protocols — the industry standard for safe and effective mold removal — and documents every step of the process so you have a verifiable record of what was found, what was done, and what clearance testing confirmed. 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.
The goal of structural drying isn't just to make the air feel dryer or to run fans for a few days — it's to return every material in the affected area to its documented equilibrium moisture content, verified by calibrated instruments, before any reconstruction begins. We deploy industrial LGR dehumidifiers and high-velocity air movers in a calculated configuration based on the square footage, material types, and psychrometric conditions specific to your Hampton property — not a one-size-fits-all equipment drop.
Our claim coordinators assigned to Hampton jobs prepare documentation packages that include every element a NH 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. Our approach to insurance coordination in Hampton is built on the principle that your policy was paid to cover a genuine loss, and our job is to make sure it pays what it's supposed to.

COS Water Damage Restoration's Hampton-based crews bring none of those disadvantages — our technicians know Hampton, work in Hampton's neighborhoods regularly, understand the construction patterns and material choices common in different parts of the city, and are invested in the reputation we've built here job by job.
Our Hampton technicians bring this material-specific knowledge to every assessment and use it to build drying plans that work for your specific property rather than applying a generic template.
Hampton's weather patterns contribute to the types of water damage events we see most frequently here — and our crews are prepared for the specific scenarios that Hampton property owners face more often than those in other markets.
Water damage restoration costs in Hampton 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. Most residential water damage events in Hampton fall within a range that homeowner insurance covers significantly, which is why our insurance coordination service is so valuable — we help make sure your policy pays what it should so your out-of-pocket is minimal.

These are the experiences of your neighbors in Hampton — unedited, firsthand accounts of working with our local restoration team.
"I run a small business in Hampton 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 Hampton."
"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 Hampton."
"I had a fear that calling a restoration company would mean getting upsold on everything and being pressured into expensive services I didn't need. COS Water Damage Restoration was the complete opposite of that experience. The technician explained the moisture readings to me at each sensor point, showed me why certain materials needed to be addressed and others could be left in place, and gave me an honest assessment of what the insurance would likely cover versus what might be out of pocket. No pressure, no inflated scope — just honest professional advice and excellent execution. My Hampton neighbors have my standing recommendation for them."
