Water damage in New Hampshire, NH moves fast. Moisture penetrates walls, soaks subfloors, and creates the conditions for mold growth within 24 to 48 hours of initial exposure. COS Water Damage Restoration's New Hampshire, NH Structural Drying teams are experienced, certified, and stationed throughout New Hampshire, NH to deliver professional water damage cleanup with full insurance coordination.

When water damage strikes in New Hampshire, NH, property owners call COS Water Damage Restoration because we've earned a reputation for fast response, certified workmanship, and the kind of honest communication that's rare in the restoration industry.
We invest heavily in our equipment and our people because the quality of your restoration experience depends entirely on both.
COS Water Damage Restoration takes on your insurance claim as part of the service — not as an add-on, and not as an upsell.
Our New Hampshire, NH crews don't follow a one-size-fits-all restoration template; they draw on deep familiarity with local building materials, regional weather patterns, and the specific drying conditions in New Hampshire, NH to build a drying plan that works.
Whether you're in a historic home with plaster walls and original hardwood floors, a modern construction with engineered materials, or a commercial facility with industrial-grade finishes, our New Hampshire, NH technicians know how to approach each material type and get it dry the right way.

COS Water Damage Restoration offers a full spectrum of Structural Drying services in New Hampshire, NH — from the moment water enters your property to the day your home or business is fully restored and handed back to you.
We use truck-mounted extraction units delivering commercial-grade suction power, paired with portable systems for access to tight spaces like closets, crawlspaces, and enclosed areas where wheeled units can't reach. We don't leave a property after extraction without starting the drying process — every job transitions immediately from extraction to structural drying setup so there's no overnight gap where mold gets a head start.
Our IICRC-certified technicians handle all residential water damage categories, from clean water supply-line failures (Category 1) to greywater events like washing machine overflows (Category 2) and contaminated sewage situations (Category 3). Hardwood floor drying is a specialty — we use specialized mat drying systems that can often save original hardwood that would otherwise require replacement, protecting both your investment and your home's character.
Commercial water damage in New Hampshire, NH carries a unique urgency that goes beyond property damage — every hour your facility is non-operational represents direct revenue loss, customer disruption, and potential liability. Our large-loss commercial equipment fleet includes diesel-powered trailer units for high-volume extraction, three-phase power desiccant dehumidifiers for high-capacity moisture removal, and industrial air movers in quantities sufficient to cover tens of thousands of square feet in a single setup.
Property owners often complete a water damage restoration and assume the job is done, not realizing that residual moisture in wall framing, subfloor assemblies, or behind baseboards has already triggered mold colonization that won't become visible for weeks. We don't attempt to "clean" mold off drywall with bleach — we remove the affected material, treat the structural assembly behind it, verify clearance with post-remediation air quality testing, and document the entire process in a written remediation report.
Professional structural drying is a science, and one that most property owners have never had to think about until they're dealing with a flood. We monitor daily and document every moisture reading throughout the drying cycle, creating a written record that proves the structure was returned to acceptable moisture levels — not just that equipment was running for a few days.
COS Water Damage Restoration removes that burden entirely by assigning a dedicated claim coordinator to your job from the moment we're on site. Our claim documentation packages for New Hampshire, NH properties include structured photo evidence organized by room and damage category, moisture-mapping reports that show the full extent of water migration, daily drying logs with instrument readings, a written scope of work using industry-standard Xactimate line items, and a narrative damage summary that explains the cause and extent of the loss in terms your adjuster can act on.



Don't wait to call — every minute of water exposure in your New Hampshire, NH property multiplies the damage and the cost.

"I manage a small apartment building in New Hampshire, NH and have dealt with several water damage events over the years. COS Water Damage Restoration is the only restoration company I will call going forward. Their response time is genuinely fast, their documentation is thorough enough that my insurance carrier processed the last two claims without a single back-and-forth, and their technicians treat every unit with the same care regardless of size. They make a stressful situation manageable."
"After a severe weather event dumped water through a failed window seal and soaked an entire wall of our living room, I got three quotes from local contractors in New Hampshire, NH. COS Water Damage Restoration was not the cheapest — but they were the only ones who used moisture detection equipment during the estimate to show me exactly where the water had traveled, which turned out to be further than I could see. Their scope of work was the most comprehensive, their documentation was the most thorough, and my insurance adjuster told me it was one of the cleanest claims she'd processed in months. Worth every penny."
"As a commercial property owner in New Hampshire, NH, I've had to deal with two significant water damage events in the past three years. The first time, I used a local contractor who did adequate work but left me to deal with the insurance company completely on my own — that process took months and I left money on the table. The second time, I called COS Water Damage Restoration. They handled the entire claim from documentation to adjuster communication to supplement filing, and we received a settlement that fully covered the restoration. Night and day difference."
