When water damage hits your home or business in Longview, 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 Longview-based Water Damage Repair teams are licensed, certified, and ready around the clock.
Positioned in Longview for fast local response every time.
Certified professionals, not unlicensed laborers.
Written estimate in your hands before any work begins.
We build your claim file and deal with your adjuster directly.
COS Water Damage Restoration's Longview team isn't a remote dispatch forwarding your call to whoever happens to be available — we maintain a dedicated local operation in Longview with crew members who live and work in the community, understand the local building stock, and know the fastest routes to your neighborhood at any hour.
Every technician who arrives at your Longview 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 Longview's housing stock.
Our reputation in Longview 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 Longview 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. Call +1-844-499-0972 the moment you discover water in your Longview property — our dispatcher will guide you through immediate protective steps while our crew is already on the way.
For Longview 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. Daily check-ins from your project manager keep you informed throughout the drying cycle, and reconstruction doesn't begin until documented moisture readings confirm every structural assembly has reached target levels.
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. Our Longview commercial team has experience with office buildings, multi-tenant retail spaces, restaurants and hospitality properties, warehouses and light industrial facilities, medical and professional offices, and multi-family residential properties.
COS Water Damage Restoration's mold remediation team in Longview 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. We never treat mold as a surface problem or attempt to cover it with encapsulants when removal is required — our remediation approach is based on assessment of the affected material and what the manufacturer and IICRC standards recommend for each scenario.
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 Longview 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.
Longview property owners dealing with water damage face two simultaneous challenges: the physical restoration of their property, and the administrative challenge of filing and navigating an insurance claim. We've worked with every major insurer serving Longview and Longview, WA and understand the specific documentation standards, turnaround expectations, and adjuster assignment processes that each carrier follows — knowledge that translates into faster claim approvals and fewer disputes.



Our Longview crew is on standby — call now and someone is heading to your door in under an hour.

Water damage restoration costs in Longview vary based on several factors: the volume of water, the category of water (clean vs. contaminated), the materials affected, the square footage involved, and the extent of mold risk.

Real reviews from Longview, WA property owners who called COS Water Damage Restoration when water threatened their homes and businesses.
"I run a small business in Longview 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 Longview."
"The burst pipe situation in our Longview 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 Longview 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."
