When water damage hits your home or business in Lee, you need a local crew that can actually show up fast — not a call center routing your emergency to a contractor two hours away. COS Water Damage Restoration's Lee-based Water Damage Repair teams are on standby 24/7 with equipment staged and crews briefed.
Local Lee crews on standby — not dispatched from out of the area.
Certified professionals, not unlicensed laborers.
No hidden fees, no last-minute line items.
Works with all major NH insurers.
COS Water Damage Restoration's Lee team isn't a remote dispatch forwarding your call to whoever happens to be available — we maintain a dedicated local operation in Lee with crew members who live and work in the community, understand the local building stock, and know the fastest routes to your neighborhood at any hour.
We bring enterprise-grade extraction and drying equipment to every Lee 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 Lee 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.

Every service listed below is available 24/7 in Lee — no wait lists, no "call back during business hours," no sending you to a subcontractor we can't vouch for.
When a pipe bursts, a basement floods, or a storm drives water into your Lee home or business, the standing water you're looking at is only the beginning of the problem. Lee'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.
For Lee homeowners, water damage is one of the most disruptive and stressful events a family can face — and the quality of the restoration company you choose determines not just how fast you get back to normal, but how thoroughly the problem is actually resolved. Our moisture mapping process identifies every area where water has penetrated — not just what's visible on the surface, but the moisture inside wall assemblies, under flooring systems, and in ceiling cavities — so that the drying plan we build addresses the complete scope of moisture, not just the obvious puddles.
COS Water Damage Restoration's commercial restoration operation in Lee 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 Lee 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 Lee 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. We never treat mold as a surface problem or attempt to cover it with encapsulants when removal is required — our remediation approach is based on assessment of the affected material and what the manufacturer and IICRC standards recommend for each scenario.
Professional structural drying in Lee is the phase of water damage restoration that most homeowners understand least — and the one that most directly determines whether the restoration holds up long-term or creates ongoing problems. 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 Lee property — not a one-size-fits-all equipment drop.
COS Water Damage Restoration takes the second challenge entirely off your hands — from the first notice of loss through final settlement — so you can focus on your family and your recovery rather than on paperwork, phone calls, and adjuster negotiations. Our approach to insurance coordination in Lee 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.



Don't wait to call — our Lee emergency line is live 24/7 and help is closer than you think.
📞 Call +1-844-499-0972 — Lee Emergency LineSpeed, transparency, local expertise, and accountability — here's how COS Water Damage Restoration delivers all four for Lee property owners.
When you call COS Water Damage Restoration in Lee, the crew that shows up actually works here.
Our Lee dispatch target is 60 minutes or less from your call to a crew at your door — and we hit that target consistently because we're positioned locally, not dispatched from another city.
Flat-rate pricing means the number on your estimate matches the number on your final invoice, assuming no scope changes.
Certified technicians apply science-based drying principles that produce better outcomes faster — not gut-feel approaches that leave moisture behind.
Better tools mean faster drying, more thorough moisture removal, and far less risk of mold development or structural damage after the job is complete.
We file the claim, deal with the adjuster, and fight for a fair settlement — so you don't have to learn the insurance claims process on top of dealing with a flooded property.
Every Lee job comes with a written satisfaction guarantee — if the restoration doesn't meet our stated standard, we return and make it right at no additional cost.
No being transferred between departments, no explaining your situation to a new person every time you call, no wondering who's responsible.
Every Water Damage Repair job in Lee follows the same structured process — one we've refined over thousands of local jobs to be as fast, thorough, and transparent as possible.
Your dispatcher gathers the essential information, identifies the closest available Lee crew, and dispatches them immediately — all within the first few minutes of your call.
Our crew arrives at your Lee property and immediately begins a systematic assessment — identifying every water entry point, mapping moisture migration with detection instruments, and classifying the water category (clean, gray, or black water).
Contaminated water scenarios activate full containment protocols — antimicrobial pre-treatment, barrier installation, and regulated disposal procedures to protect your household from cross-contamination.
Equipment stays until documented readings confirm completion — not until a certain number of days has passed.
Pre-existing or emerging mold growth is addressed by our IICRC-certified remediation specialists with containment, HEPA air scrubbing, material removal, and clearance testing.
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.
COS Water Damage Restoration's Lee-based crews bring none of those disadvantages — our technicians know Lee, work in Lee'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.
Lee'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.
Lee'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 Lee property owners face more often than those in other markets.
Water damage restoration costs in Lee 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 Lee 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.

Real reviews from Lee, NH property owners who called COS Water Damage Restoration when water threatened their homes and businesses.
"I run a small business in Lee 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 Lee."
"The burst pipe situation in our Lee rental unit was a nightmare — the tenants called me at midnight, the unit was partially flooded, and I had no idea how bad it was. COS Water Damage Restoration's crew was on site before I could even get there myself. By the time I arrived, extraction was underway and the project manager was already walking through the damage assessment with photos. I had a full scope and estimate in my email before 2 a.m. The restoration was completed on schedule, within the estimated cost, and my tenant was back in the unit within two weeks. Outstanding."
"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 Lee neighbors have my standing recommendation for them."
