Clearlake 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 Clearlake-based Water Damage Repair teams are licensed, certified, and ready around the clock.
Positioned in Clearlake for fast local response every time.
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 Clearlake 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 Clearlake 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 Clearlake's housing stock.
Our reputation in Clearlake 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.

Our integrated service model means Clearlake property owners have one phone number, one point of contact, and one company responsible for the outcome from start to finish.
In Clearlake, our emergency extraction crews maintain ready-to-deploy status every hour of every day — because the fastest response to flooding directly determines how much of your property can be saved. Clearlake's Water Damage Repair emergency calls include everything from clean water supply line failures to contaminated sewage backflows, and our crews are trained and equipped for every category of water damage — with the right PPE, containment protocols, and extraction methods for each situation.
For Clearlake homeowners, water damage is one of the most disruptive and stressful events a family can face — and the quality of the restoration company you choose determines not just how fast you get back to normal, but how thoroughly the problem is actually resolved. For Clearlake 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.
We work in occupied buildings, schedule around your operating hours when it's possible to do so safely, and produce the detailed loss documentation that commercial insurance adjusters require — all as standard practice, not a premium option. Whether the loss is a small office suite or an entire floor of a commercial building, COS Water Damage Restoration's Clearlake commercial team has the experience and equipment to handle it.
COS Water Damage Restoration's mold remediation team in Clearlake 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 Clearlake drying crews take measurement seriously and don't sign off on a project until the numbers confirm completion. Your project manager reviews the daily readings with you or provides them by phone or message on request, and reconstruction planning begins only after final readings confirm compliance with drying targets across all affected assemblies.
Our claim coordinators assigned to Clearlake 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 Clearlake 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.

Real reviews from Clearlake, WA property owners who called COS Water Damage Restoration when water threatened their homes and businesses.
"I run a small business in Clearlake and had a toilet supply line failure on a Sunday night that flooded my office suite and spread into the common hallway. I called COS Water Damage Restoration, who answered immediately, and had a crew at the building in under an hour. They worked through the night to extract the water and set up drying equipment before we opened Monday morning. My employees came in to a building that was functional — inconvenient, but operational. The insurance claim was handled entirely by their coordinator and settled in less than three weeks. I recommend them to every business owner I know in Clearlake."
"The burst pipe situation in our Clearlake 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 Clearlake 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."
