A flood in Gillette doesn't get better by waiting, and the cost of delay is measured in thousands of dollars of preventable damage. COS Water Damage Restoration's Gillette-based Water Damage Repair teams are on standby 24/7 with equipment staged and crews briefed.
Positioned in Gillette for fast local response every time.
Certified professionals, not unlicensed laborers.
No hidden fees, no last-minute line items.
We build your claim file and deal with your adjuster directly.
Water damage in Gillette moves on its own timeline, which is why our local dispatch operation stays fully staffed around the clock, every day of the year — so that when the call comes in at 2 a.m., the crew heading to your door is already mobilized.
Every technician who arrives at your Gillette property carries current IICRC WRT (Water Damage Restoration Technician) certification, a background-check clearance, and familiarity with the specific materials and construction methods common in Gillette's housing stock.
COS Water Damage Restoration has earned the trust of Gillette 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.

Our integrated service model means Gillette property owners have one phone number, one point of contact, and one company responsible for the outcome from start to finish.
When a pipe bursts, a basement floods, or a storm drives water into your Gillette home or business, the standing water you're looking at is only the beginning of the problem. 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.
We approach every Gillette 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. 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 Gillette 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 Gillette 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 Gillette 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. Post-remediation air quality testing provides objective confirmation that the remediation was successful, and the written clearance report we issue becomes part of your property's maintenance record.
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 Gillette 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 Gillette 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. 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.

That local context makes our assessments more accurate, our response timelines more reliable, and our client communication more informed.
Water damage restoration costs in Gillette 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.

Real reviews from Gillette, WY property owners who called COS Water Damage Restoration when water threatened their homes and businesses.
"I run a small business in Gillette 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 Gillette."
"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 Gillette."
"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 Gillette neighbors have my standing recommendation for them."
