When water damage hits your home or business in Appleton, 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 Appleton-based Water Damage Repair teams are on standby 24/7 with equipment staged and crews briefed.
Local Appleton crews on standby — not dispatched from out of the area.
Every technician holds current WRT certification — the industry standard.
Written estimate in your hands before any work begins.
Works with all major WA insurers.
Water damage in Appleton 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.
We bring enterprise-grade extraction and drying equipment to every Appleton job — not the rental-store grade equipment that leaves moisture in wall cavities and under flooring that causes mold weeks after the job was supposedly done.
If you've already experienced water damage in Appleton and need someone to respond right now, call +1-844-499-0972 — our local crew is ready.

Our integrated service model means Appleton property owners have one phone number, one point of contact, and one company responsible for the outcome from start to finish.
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.
Our residential restoration teams in Appleton are experienced across the full range of home types found in the area — older homes with original hardwood and plaster, newer construction with engineered materials and finished basements, and everything in between. For Appleton homeowners with original hardwood floors, our floor mat drying systems often allow us to dry hardwood in place rather than requiring replacement — a significant cost savings and a result that preserves the character of your home.
COS Water Damage Restoration's commercial restoration operation in Appleton is built for speed and scale — with crew sizes that grow to meet the scope of the loss, equipment inventories that cover large square footages, and project management that keeps business owners and property managers informed without requiring them to micromanage the process. Commercial jobs in Appleton receive a dedicated project manager who handles all carrier communication, adjuster scheduling, supplement filing, and daily progress reporting — leaving business owners and property managers free to focus on their operations rather than managing a restoration project.
Mold is the almost-inevitable consequence of water damage that wasn't addressed quickly or completely — and in Appleton's climate, wet building materials can support mold growth in as little as 24 to 48 hours after initial exposure. 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.
The goal of structural drying isn't just to make the air feel dryer or to run fans for a few days — it's to return every material in the affected area to its documented equilibrium moisture content, verified by calibrated instruments, before any reconstruction begins. 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.
Our claim coordinators assigned to Appleton jobs prepare documentation packages that include every element a WA insurance adjuster needs to process a water damage claim efficiently: structured photo evidence, moisture data logs, equipment records, and a complete Xactimate scope of work that mirrors how your carrier's own systems calculate cost estimates. Our approach to insurance coordination in Appleton 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 Appleton 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 Appleton 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."
"After storm water came through our basement window well during a major rain event, I was at a loss. I had an inch of standing water across the whole basement and no idea who to call. A neighbor recommended COS Water Damage Restoration and I'm glad she did. The crew arrived quickly, immediately identified that the water had already gotten under the vinyl plank flooring, and explained everything they were going to do before they started. The drying took a week — they checked in every single day — and when it was done the insurance settled the claim at the full documented amount. I've since recommended COS Water Damage Restoration to three other people in Appleton."
"Mold found during the renovation of our Appleton 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."
