The moment your call connects, our Mazomanie restoration dispatcher starts building your response. Extraction crews arrive with truck-mounted systems capable of removing high volumes of water rapidly — limiting saturation time and reducing the overall restoration scope.
Every affected assembly is documented with instrument readings before drying begins.
Drying isn't complete until the numbers confirm it — not when a certain number of days have passed.
We don't rebuild over hidden mold risk.
Our Mazomanie claim coordinators build your documentation file from day one: structured photo evidence, moisture data logs, equipment placement records, and an Xactimate scope of work that matches your carrier's estimating platform. We file, communicate with your adjuster, and follow the claim through to settlement so you don't have to.
One company, start to finish.

"Our Mazomanie business had a roof-to-slab water event on a Thursday night. By Friday morning COS Water Damage Restoration had extracted everything, staged drying equipment, and given me a documented scope I could hand directly to my adjuster. We were operational again the following week. Truly professional."
"I was terrified the hardwood floors in our Mazomanie home were gone after the flooding. The COS Water Damage Restoration crew brought in mat drying systems and dried them in place — saved us thousands versus replacement. The project manager called every morning with readings. Outstanding."
"Mold discovered during our Mazomanie renovation led us to COS Water Damage Restoration. The remediation was thorough, the clearance report was accepted by our contractor and insurer on the first submission, and we were back on schedule within the week."
