Lyme 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 Lyme-based Water Damage Repair teams are licensed, certified, and ready around the clock.
Positioned in Lyme for fast local response every time.
Certified professionals, not unlicensed laborers.
No hidden fees, no last-minute line items.
Works with all major NH insurers.
We've handled everything from flash-flood basement extractions in Lyme'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 Lyme 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.
Our reputation in Lyme is built on one job at a time — and we protect it by treating every property we work in with the same professionalism we'd want if it were our own home or business being restored.

Our integrated service model means Lyme property owners have one phone number, one point of contact, and one company responsible for the outcome from start to finish.
In Lyme, our emergency extraction crews maintain ready-to-deploy status every hour of every day — because the fastest response to flooding directly determines how much of your property can be saved. Lyme'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 Lyme 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. Daily check-ins from your project manager keep you informed throughout the drying cycle, and reconstruction doesn't begin until documented moisture readings confirm every structural assembly has reached target levels.
COS Water Damage Restoration's commercial restoration operation in Lyme is built for speed and scale — with crew sizes that grow to meet the scope of the loss, equipment inventories that cover large square footages, and project management that keeps business owners and property managers informed without requiring them to micromanage the process. Our Lyme 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.
Mold is the almost-inevitable consequence of water damage that wasn't addressed quickly or completely — and in Lyme's climate, wet building materials can support mold growth in as little as 24 to 48 hours after initial exposure. HEPA filtration, containment barriers, negative air pressure, and proper PPE are standard on every Lyme 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 Lyme drying crews take measurement seriously and don't sign off on a project until the numbers confirm completion. 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 Lyme property — not a one-size-fits-all equipment drop.
Lyme property owners dealing with water damage face two simultaneous challenges: the physical restoration of their property, and the administrative challenge of filing and navigating an insurance claim. Our approach to insurance coordination in Lyme 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.

📞 Call +1-844-499-0972 — Lyme Emergency LineSpeed, transparency, local expertise, and accountability — here's how COS Water Damage Restoration delivers all four for Lyme property owners.
We're not a call center forwarding your Lyme emergency to a regional contractor — we have crews stationed locally in Lyme, ready to deploy immediately.
Speed of response is the single most controllable factor in limiting water damage costs — and we've optimized our Lyme operation around it.
In Lyme, COS Water Damage Restoration never starts work without providing a written, itemized estimate that you've approved — no exceptions, no gray areas.
IICRC WRT certification is the baseline requirement for every technician we deploy in Lyme — no unlicensed laborers, no trainees working without supervision.
Lyme jobs get industrial LGR dehumidifiers, truck-mounted extraction, thermal imaging cameras, and moisture mapping arrays — not residential-grade rental equipment.
Supplement filing for underpaid claims is part of the service — because we believe your policy should pay what your loss is documented to be.
Five-star reviews are earned, not purchased — and they reflect what happens when every technician takes personal pride in the outcome of every job.
No being transferred between departments, no explaining your situation to a new person every time you call, no wondering who's responsible.
Here's exactly what happens when you call COS Water Damage Restoration for water damage in Lyme, from the moment the phone rings to the day we hand your property back.
You call +1-844-499-0972 and a live Lyme dispatcher answers — no voicemail, no call tree, no waiting on hold during your emergency.
You receive a clear verbal briefing and a written estimate scope before any work begins.
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.
Antimicrobial treatment is applied to all moisture-exposed surfaces as a standard preventive step — stopping mold colonization before it can take hold in your Lyme property's structural assemblies.
The final walkthrough is conducted with you personally, confirming satisfaction with every element before we close out the job and hand you your warranty documentation.
When a restoration company sends a crew to your Lyme property who has never worked in the area, the difference in performance is real — and it shows up in ways that matter: slower navigation to your address, unfamiliarity with local building code requirements that affect how drying and reconstruction are approached, no relationship with local supply vendors that allows materials to be sourced quickly, and no reputation to protect within the community they're serving.
Lyme's mix of housing stock — from older historic homes to newer construction developments — presents a range of material and structural challenges that our crews encounter regularly.
Lyme'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 Lyme property owners face more often than those in other markets.
Water damage restoration costs in Lyme 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 Lyme 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.
If you're a property owner in Lyme who has just discovered water damage — whether it's an active flood or moisture you noticed during an inspection — your best first call is +1-844-499-0972.

Real reviews from Lyme, NH property owners who called COS Water Damage Restoration when water threatened their homes and businesses.
"We had a washing machine overflow that soaked the laundry room and wicked into the adjacent bedroom overnight before we noticed it. I found it in the morning and called COS Water Damage Restoration immediately. Their crew was at my Lyme house in 55 minutes — which was remarkable given that I called at 7 a.m. on a Saturday. They found moisture under the bedroom baseboard that I never would have caught, set up drying equipment that ran for five days, and the project manager called me with readings every morning. No mold, no lingering smell, and the claim went through without a single request for additional documentation. Absolute professionals."
"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 Lyme."
"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 Lyme neighbors have my standing recommendation for them."
