Here's what separates COS Water Damage Restoration's Water Damage Restoration service from every other option in Madison.
Every technician holds active WI contractor licensing and IICRC WRT certification. Full general liability and workers' comp coverage is in force on every Madison job.
Locally staged equipment and crews mean our Madison response time beats out-of-area contractors every time.
Xactimate-based scope of work reviewed with you before any equipment is placed. The estimate you approve is the invoice you receive — no hidden line items, no after-the-fact surprises.
Every Water Damage Restoration job in Madison carries our written satisfaction guarantee. If the result doesn't meet the documented standard, we return and make it right at zero additional cost.
Our Madison Water Damage Restoration team handles every phase of recovery in-house: no subcontracting, no coordination gaps, no handoff problems.
Speed at this phase directly determines how much is salvageable. Our Madison crews don't slow down on the way to your property.
Every affected assembly is documented with instrument readings before drying begins.
Industrial LGR dehumidifiers and high-velocity air movers are deployed in calculated configurations based on your Madison property's materials, square footage, and psychrometric conditions. Daily readings at fixed sensor points document the drying progression until all assemblies reach target equilibrium moisture content.
Antimicrobial treatment is applied to all moisture-exposed structural surfaces as a standard preventive step in every Madison Water Damage Restoration job. Where mold growth is identified, IICRC S520-compliant remediation — with HEPA containment, negative air pressure, and clearance testing — is performed before reconstruction begins.
Our Madison 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.
When drying is confirmed complete, our licensed Madison reconstruction team handles all rebuild work — drywall, flooring, painting, trim, structural framing — under the same project manager who ran the restoration phase. No handoff to an unknown subcontractor, no coordination gap, no restart of the communication process.


Real person, real dispatch. Call +1-844-499-0972 and your Madison crew is moving before you hang up.
Our Madison crew targets on-site arrival in 60 minutes or less, staging extraction equipment and containment supplies during transit so they're productive the moment they arrive.
No work starts without your written approval of the scope and cost.
Written satisfaction guarantee on every Madison job.

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."
"The insurance side of a water damage claim is overwhelming. COS Water Damage Restoration's Madison team handled everything — filed the first notice, attended the adjuster visit, and got us a fair settlement. I didn't make a single insurance phone call myself."
"Mold discovered during our Madison 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."
