Loudon property owners dealing with water damage have one smart move: call COS Water Damage Restoration and get a local crew on site within the hour. COS Water Damage Restoration's Loudon-based Water Damage Repair teams are licensed, certified, and ready around the clock.
Local Loudon crews on standby — not dispatched from out of the area.
Certified professionals, not unlicensed laborers.
Written estimate in your hands before any work begins.
Works with all major NH insurers.
We've handled everything from flash-flood basement extractions in Loudon'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.
We bring enterprise-grade extraction and drying equipment to every Loudon job — not the rental-store grade equipment that leaves moisture in wall cavities and under flooring that causes mold weeks after the job was supposedly done.
If you've already experienced water damage in Loudon 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 Loudon — 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. Loudon's Water Damage Repair emergency calls include everything from clean water supply line failures to contaminated sewage backflows, and our crews are trained and equipped for every category of water damage — with the right PPE, containment protocols, and extraction methods for each situation.
We approach every Loudon 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. For Loudon homeowners with original hardwood floors, our floor mat drying systems often allow us to dry hardwood in place rather than requiring replacement — a significant cost savings and a result that preserves the character of your home.
We work in occupied buildings, schedule around your operating hours when it's possible to do so safely, and produce the detailed loss documentation that commercial insurance adjusters require — all as standard practice, not a premium option. Our Loudon 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.
Many Loudon homeowners discover mold weeks or months after a water event that they thought had been fully addressed, because invisible moisture remained in wall cavities, beneath flooring, or in attic insulation after a surface-only cleanup. HEPA filtration, containment barriers, negative air pressure, and proper PPE are standard on every Loudon mold remediation job — protecting your household members and our crews from exposure to dislodged spores during the removal process.
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 Loudon drying crews take measurement seriously and don't sign off on a project until the numbers confirm completion. Your project manager reviews the daily readings with you or provides them by phone or message on request, and reconstruction planning begins only after final readings confirm compliance with drying targets across all affected assemblies.
Our claim coordinators assigned to Loudon 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. We've worked with every major insurer serving Loudon and Loudon, NH and understand the specific documentation standards, turnaround expectations, and adjuster assignment processes that each carrier follows — knowledge that translates into faster claim approvals and fewer disputes.

We're not a call center forwarding your Loudon emergency to a regional contractor — we have crews stationed locally in Loudon, ready to deploy immediately.

Your Loudon home or business deserves the professionalism that certification represents.

One contact, complete accountability, from start to finish.
Every Water Damage Repair job in Loudon follows the same structured process — one we've refined over thousands of local jobs to be as fast, thorough, and transparent as possible.
You call +1-844-499-0972 and a live Loudon dispatcher answers — no voicemail, no call tree, no waiting on hold during your emergency.
Thermal imaging cameras reveal moisture in wall assemblies and under flooring that isn't yet visible on the surface — giving us a complete picture of the damage before we build the response plan.
We extract completely and transition directly to drying setup without an overnight gap where mold begins to grow.
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.
We coordinate the reconstruction scope with your insurance carrier's supplement process before work begins, so funding is in place and there are no payment delays.
COS Water Damage Restoration's Loudon-based crews bring none of those disadvantages — our technicians know Loudon, work in Loudon'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.
Older Loudon homes with original hardwood flooring, plaster walls, and basement moisture histories require different drying strategies than newer builds with engineered hardwood, drywall, and open-plan floor plans that allow air movement differently.
Whether it's the spring flooding pattern, the summer storm profile, or the winter freeze-thaw cycle that affects Loudon's plumbing, we approach Loudon jobs with an awareness of local conditions that an out-of-area contractor simply can't replicate.
Water damage restoration costs in Loudon 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 Loudon 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. Call +1-844-499-0972 for a free on-site estimate with no obligation to proceed — we'll give you a clear picture of scope and cost before you commit to anything.
Our Loudon dispatcher will ask you a few quick questions to characterize the situation, tell you what to do (and what not to do) while our crew is in transit, and give you an honest arrival estimate so you're not left wondering.

Real reviews from Loudon, NH property owners who called COS Water Damage Restoration when water threatened their homes and businesses.
"I run a small business in Loudon 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 Loudon."
"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 Loudon."
"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 Loudon neighbors have my standing recommendation for them."
