Our Old Lyme crew lead coordinates directly with your insurance carrier from the moment we arrive on site — building the documentation package, scheduling the adjuster walkthrough, and following up on open claim items until your settlement is confirmed and you can move forward with reconstruction.

COS Water Damage Restoration provides comprehensive Water Damage Repair in Old Lyme — covering every phase from emergency extraction through mold remediation, structural drying, and full reconstruction, all managed by our local Old Lyme crew.
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. After extraction, we don't pack up and leave — we immediately stage the drying equipment that will begin drawing moisture from structural assemblies before mold has a chance to gain a foothold.
Our residential restoration teams in Old Lyme are experienced across the full range of home types found in the area — older homes with original hardwood and plaster, newer construction with engineered materials and finished basements, and everything in between. 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 Old 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. Whether the loss is a small office suite or an entire floor of a commercial building, COS Water Damage Restoration's Old Lyme commercial team has the experience and equipment to handle it.
COS Water Damage Restoration's mold remediation team in Old Lyme follows IICRC S520 protocols — the industry standard for safe and effective mold removal — and documents every step of the process so you have a verifiable record of what was found, what was done, and what clearance testing confirmed. 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.
The goal of structural drying isn't just to make the air feel dryer or to run fans for a few days — it's to return every material in the affected area to its documented equilibrium moisture content, verified by calibrated instruments, before any reconstruction begins. Daily moisture readings are taken at consistent sensor points throughout the drying cycle and recorded in a written log that documents the progress of drying over time — useful for your insurance file and for your own records.
Old 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. We've worked with every major insurer serving Old Lyme and Old Lyme, CT 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 accountable for our work because our reputation in Old Lyme is built one job at a time, and we take that seriously.
One contact, complete accountability, from start to finish.
Every Water Damage Repair job in Old Lyme follows the same structured process — one we've refined over thousands of local jobs to be as fast, thorough, and transparent as possible.
You receive your crew's estimated arrival time before you hang up, and a direct callback number if anything changes en route.
Our crew arrives at your Old Lyme 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).
With the scope confirmed and your approval in hand, extraction begins immediately using the highest-capacity equipment appropriate for the situation.
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.
Our licensed reconstruction team handles all Old Lyme rebuilding work — drywall, flooring, painting, trim, and structural repairs — under the same project management as the restoration phase.
When a restoration company sends a crew to your Old 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.
Older Old Lyme 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.
That local context makes our assessments more accurate, our response timelines more reliable, and our client communication more informed.
Water damage restoration costs in Old 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 Old 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.
Our Old Lyme 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 Old Lyme, CT 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 Old 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."
"The burst pipe situation in our Old Lyme 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 Old Lyme neighbors have my standing recommendation for them."
