When water damage hits your home or business in Groton, 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 Groton-based Water Damage Repair teams are on standby 24/7 with equipment staged and crews briefed.
Positioned in Groton for fast local response every time.
Every technician holds current WRT certification — the industry standard.
No hidden fees, no last-minute line items.
Works with all major SD insurers.
We've handled everything from flash-flood basement extractions in Groton'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.
Our Groton 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 has earned the trust of Groton homeowners, landlords, property managers, and commercial facility owners because we consistently do what we say we'll do: we arrive when we say we'll arrive, we provide the estimate we quoted, we complete the documentation we promised, and we stand behind the work with a written satisfaction guarantee.

Every service listed below is available 24/7 in Groton — no wait lists, no "call back during business hours," no sending you to a subcontractor we can't vouch for.
In Groton, 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. 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 Groton 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. 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.
Water damage to a commercial property in Groton isn't just a property issue — it's a business interruption event that starts costing revenue from the moment the damage begins. Whether the loss is a small office suite or an entire floor of a commercial building, COS Water Damage Restoration's Groton commercial team has the experience and equipment to handle it.
Many Groton 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 Groton 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 Groton 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 Groton property — not a one-size-fits-all equipment drop.
Groton 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 Groton and Groton, SD 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.

A calculated drying plan is implemented immediately following extraction — air movers and dehumidifiers placed based on psychrometric data specific to your Groton property's materials and conditions.

Real reviews from Groton, SD 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 Groton 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 Groton 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 Groton neighbors have my standing recommendation for them."
