COS Water Damage Restoration offers a full spectrum of Flood Damage Cleanup 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.

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. 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.

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.
Your coordinator prepares your complete loss documentation, contacts your carrier, schedules the adjuster walkthrough, and follows up on outstanding items in your claim — all without you having to manage it. 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.

📞 Call +1-844-499-0972 — New Hampshire, NH Flood Damage Cleanup ExpertsRead what your neighbors throughout New Hampshire, NH experienced when they called COS Water Damage Restoration.
"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."
"We had a sewage backup in our basement that left contaminated water across about 400 square feet. I was terrified about the health risks and the cleanup. COS Water Damage Restoration's team showed up in full PPE, explained the decontamination process step by step, and treated the situation with a level of professionalism that put me at ease. The area was properly contained, cleaned, treated, and tested before they declared it safe. I can't say enough good things about how they handled it."
"The team at COS Water Damage Restoration saved our hardwood floors. I was told by two other contractors that the floors would need to be torn out and replaced after our basement flooded. COS Water Damage Restoration's technician spent 20 minutes measuring moisture levels throughout the floor and proposed a mat drying program that, over six days, brought every measurement to target level. We kept the original floors. That alone made them worth every penny, and the whole experience — from the speed of the initial response to the quality of the final walkthrough — was excellent."
