Hertel property owners dealing with water damage have one smart move: call COS Water Damage Restoration and get a local crew on site within the hour. COS Water Damage Restoration's Hertel-based Water Damage Repair teams are licensed, certified, and ready around the clock.
Local Hertel crews on standby — not dispatched from out of the area.
Every technician holds current WRT certification — the industry standard.
No hidden fees, no last-minute line items.
Works with all major WI insurers.
Water damage in Hertel 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 Hertel 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 Hertel's housing stock.
Our reputation in Hertel 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 Hertel — 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.
We approach every Hertel 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.
Water damage to a commercial property in Hertel 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 Hertel commercial team has the experience and equipment to handle it.
COS Water Damage Restoration's mold remediation team in Hertel 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. 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 Hertel drying crews take measurement seriously and don't sign off on a project until the numbers confirm completion. 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.
Hertel 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. Our approach to insurance coordination in Hertel is built on the principle that your policy was paid to cover a genuine loss, and our job is to make sure it pays what it's supposed to.

Read what Hertel customers consistently say about response time, professionalism, pricing, and results.
"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 Hertel 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 Hertel 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 Hertel 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."
