When water damage hits your home or business in Keller, 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 Keller-based Water Damage Repair teams are licensed, certified, and ready around the clock.
Local Keller crews on standby — not dispatched from out of the area.
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 Keller team isn't a remote dispatch forwarding your call to whoever happens to be available — we maintain a dedicated local operation in Keller 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 Keller 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 Keller's housing stock.
If you've already experienced water damage in Keller and need someone to respond right now, call +1-844-499-0972 — our local crew is ready.

Every service listed below is available 24/7 in Keller — no wait lists, no "call back during business hours," no sending you to a subcontractor we can't vouch for.
When a pipe bursts, a basement floods, or a storm drives water into your Keller home or business, the standing water you're looking at is only the beginning of the problem. 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.
We approach every Keller residential job with the understanding that we're working inside someone's home, and that means treating the space with care, communicating clearly about what we're doing and why, and keeping the disruption to your family's daily life as minimal as possible. For Keller 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.
Water damage to a commercial property in Keller isn't just a property issue — it's a business interruption event that starts costing revenue from the moment the damage begins. Our Keller 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.
Many Keller homeowners discover mold weeks or months after a water event that they thought had been fully addressed, because invisible moisture remained in wall cavities, beneath flooring, or in attic insulation after a surface-only cleanup. 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.
Professional structural drying in Keller is the phase of water damage restoration that most homeowners understand least — and the one that most directly determines whether the restoration holds up long-term or creates ongoing problems. 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 Keller 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. If your adjuster's initial settlement offer doesn't fully account for the documented scope of loss, we prepare and file a supplement with supporting evidence — a step that many homeowners don't know they can take and that frequently results in additional covered compensation.

One contact, complete accountability, from start to finish.
Every Water Damage Repair job in Keller follows the same structured process — one we've refined over thousands of local jobs to be as fast, thorough, and transparent as possible.
You call +1-844-499-0972 and a live Keller dispatcher answers — no voicemail, no call tree, no waiting on hold during your emergency.
You receive a clear verbal briefing and a written estimate scope before any work begins.
We extract completely and transition directly to drying setup without an overnight gap where mold begins to grow.
A calculated drying plan is implemented immediately following extraction — air movers and dehumidifiers placed based on psychrometric data specific to your Keller property's materials and conditions.
A written remediation report is issued that documents every action taken and every clearance measurement recorded.
The final walkthrough is conducted with you personally, confirming satisfaction with every element before we close out the job and hand you your warranty documentation.
That local familiarity translates into faster arrival, fewer logistical delays, better-informed scope assessments, and the kind of personal accountability that comes from knowing your work might be reviewed by someone who lives down the street.
Older Keller homes with original hardwood flooring, plaster walls, and basement moisture histories require different drying strategies than newer builds with engineered hardwood, drywall, and open-plan floor plans that allow air movement differently.
That local context makes our assessments more accurate, our response timelines more reliable, and our client communication more informed.
Water damage restoration costs in Keller 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. Most residential water damage events in Keller fall within a range that homeowner insurance covers significantly, which is why our insurance coordination service is so valuable — we help make sure your policy pays what it should so your out-of-pocket is minimal.

Our Keller dispatcher will ask you a few quick questions to characterize the situation, tell you what to do (and what not to do) while our crew is in transit, and give you an honest arrival estimate so you're not left wondering.

Read what Keller 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 Keller 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."
"The burst pipe situation in our Keller 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."
"I had a fear that calling a restoration company would mean getting upsold on everything and being pressured into expensive services I didn't need. COS Water Damage Restoration was the complete opposite of that experience. The technician explained the moisture readings to me at each sensor point, showed me why certain materials needed to be addressed and others could be left in place, and gave me an honest assessment of what the insurance would likely cover versus what might be out of pocket. No pressure, no inflated scope — just honest professional advice and excellent execution. My Keller neighbors have my standing recommendation for them."
