COS Water Damage Restoration offers a full spectrum of Water Extraction 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.
When water is actively flooding your property in New Hampshire, NH, extraction speed is the single most important factor in limiting your total loss. Extraction removes the free-standing water that you can see — but the first step our crews take after pulling the visible water is deploying moisture detection equipment to identify the water you can't see: the moisture that has already wicked into wall cavities, soaked beneath your flooring system, or saturated the insulation in your crawlspace.
For homeowners in New Hampshire, NH, water damage is one of the most disruptive events imaginable — it invades your personal space, disrupts your daily routines, and threatens the structural integrity and monetary value of your most important investment. We use injection drying systems to push conditioned air directly into wall cavities, preventing the need for unnecessary drywall removal when moisture levels can be reduced in place.
COS Water Damage Restoration's commercial response teams in New Hampshire, NH are sized and equipped to handle multi-floor flooding events, large square footage drying programs, and complex facilities including server rooms, commercial kitchens, and industrial production areas. 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.
By the time mold is visible on a surface, the colony has typically been growing for a significant period — and surface cleaning alone is insufficient; the source material must be properly assessed, treated, or removed. COS Water Damage Restoration's IICRC-certified mold remediation teams in New Hampshire, NH follow IICRC S520 protocols for every job, establishing containment barriers to prevent spore spread, running HEPA-filtered negative air machines to maintain negative pressure in the affected area, and safely removing and disposing of contaminated materials using regulated procedures.
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. COS Water Damage Restoration's New Hampshire, NH drying crews deploy calibrated equipment based on psychrometric calculations specific to your property — accounting for the temperature, relative humidity, specific materials present, and the volume of air to be conditioned.
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.

"I called COS Water Damage Restoration at 11 p.m. on a Friday night after our water heater failed and flooded the utility room and part of the kitchen. The dispatcher was calm, clear, and had an estimated arrival time to me within two minutes of the call ending. The crew arrived in 48 minutes, which felt like a miracle given the time. They walked me through the entire situation, got the water out, and had drying equipment running before midnight. The project manager called me every morning throughout the drying process and the final result was excellent. I've already referred two neighbors."
"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."
