Here's what separates COS Water Damage Restoration's Water Damage Restoration service from every other option in Janesville.
Every technician holds active CA contractor licensing and IICRC WRT certification. Full general liability and workers' comp coverage is in force on every Janesville job.
Locally staged equipment and crews mean our Janesville response time beats out-of-area contractors every time.
We quote in writing before we start. What you approve is what you pay.
Our reputation in Janesville is one job at a time. We stand behind every single one.
Our Janesville 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 Janesville 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 Janesville 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.
We don't rebuild over hidden mold risk.
Supplement filing for underpaid Janesville claims is part of the service.
When drying is confirmed complete, our licensed Janesville 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 Janesville crew is moving before you hang up.
Local crews mean local speed — we know Janesville's roads and we move fast.
No work starts without your written approval of the scope and cost.

"Our Janesville 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 Janesville 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."
"Three companies quoted our Janesville water damage restoration. COS Water Damage Restoration was the only one who walked every room with instruments before quoting, explained each line of the estimate, and committed to the timeline in writing. They came in on time, on scope, and the claim went through without a single supplemental dispute."
