COS Water Damage Restoration's Stonington team isn't a remote dispatch forwarding your call to whoever happens to be available — we maintain a dedicated local operation in Stonington 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 Stonington 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 Stonington 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 Stonington — 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 Stonington home or business, the standing water you're looking at is only the beginning of the problem. Stonington'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 Stonington 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. For Stonington 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.
COS Water Damage Restoration's commercial restoration operation in Stonington 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 Stonington commercial team has the experience and equipment to handle it.
Many Stonington 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.
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.
Our claim coordinators assigned to Stonington jobs prepare documentation packages that include every element a CT 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. If your adjuster's initial settlement offer doesn't fully account for the documented scope of loss, we prepare and file a supplement with supporting evidence — a step that many homeowners don't know they can take and that frequently results in additional covered compensation.

Contaminated water scenarios activate full containment protocols — antimicrobial pre-treatment, barrier installation, and regulated disposal procedures to protect your household from cross-contamination.
A calculated drying plan is implemented immediately following extraction — air movers and dehumidifiers placed based on psychrometric data specific to your Stonington property's materials and conditions.
Antimicrobial treatment is applied to all moisture-exposed surfaces as a standard preventive step — stopping mold colonization before it can take hold in your Stonington property's structural assemblies.
Our licensed reconstruction team handles all Stonington 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 Stonington 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.
Stonington'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.
That local context makes our assessments more accurate, our response timelines more reliable, and our client communication more informed.
Water damage restoration costs in Stonington 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.

Read what Stonington customers consistently say about response time, professionalism, pricing, and results.
"I run a small business in Stonington 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 Stonington."
"The burst pipe situation in our Stonington 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."
"Mold found during the renovation of our Stonington home led us to COS Water Damage Restoration for remediation. The discovery was stressful — we didn't know how extensive it was or what it meant for the timeline of our project. The COS Water Damage Restoration team came in, assessed it thoroughly, explained exactly what they found and what the IICRC-compliant remediation process looked like, and completed the job on time. The post-remediation air testing came back clear, the report they provided satisfied our contractor and our insurer, and we were back on schedule within a week. Professional from beginning to end."
