When water damage hits your home or business in Kellnersville, 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 Kellnersville-based Water Damage Repair teams are licensed, certified, and ready around the clock.
Local Kellnersville crews on standby — not dispatched from out of the area.
Certified professionals, not unlicensed laborers.
Written estimate in your hands before any work begins.
We build your claim file and deal with your adjuster directly.
Water damage in Kellnersville 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.
Our Kellnersville 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.
If you've already experienced water damage in Kellnersville and need someone to respond right now, call +1-844-499-0972 — our local crew is ready.

Every service listed below is available 24/7 in Kellnersville — no wait lists, no "call back during business hours," no sending you to a subcontractor we can't vouch for.
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.
For Kellnersville 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. 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.
We work in occupied buildings, schedule around your operating hours when it's possible to do so safely, and produce the detailed loss documentation that commercial insurance adjusters require — all as standard practice, not a premium option. Our Kellnersville 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.
COS Water Damage Restoration's mold remediation team in Kellnersville 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. HEPA filtration, containment barriers, negative air pressure, and proper PPE are standard on every Kellnersville mold remediation job — protecting your household members and our crews from exposure to dislodged spores during the removal process.
Professional structural drying in Kellnersville 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 Kellnersville 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. We've worked with every major insurer serving Kellnersville and Kellnersville, WI 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.



Don't wait to call — our Kellnersville emergency line is live 24/7 and help is closer than you think.

These are the experiences of your neighbors in Kellnersville — unedited, firsthand accounts of working with our local restoration team.
"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 Kellnersville 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 Kellnersville 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 Kellnersville 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."
