Boulder 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 Boulder-based Water Damage Repair teams are licensed, certified, and ready around the clock.
Local Boulder crews on standby — not dispatched from out of the area.
Every technician holds current WRT certification — the industry standard.
No hidden fees, no last-minute line items.
We build your claim file and deal with your adjuster directly.
We've handled everything from flash-flood basement extractions in Boulder's older neighborhoods to multi-floor commercial water events in newer construction, and every job has reinforced the same core truth: speed and expertise make the difference between a manageable repair and a catastrophic rebuild.
We bring enterprise-grade extraction and drying equipment to every Boulder 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.
COS Water Damage Restoration has earned the trust of Boulder homeowners, landlords, property managers, and commercial facility owners because we consistently do what we say we'll do: we arrive when we say we'll arrive, we provide the estimate we quoted, we complete the documentation we promised, and we stand behind the work with a written satisfaction guarantee.

Our integrated service model means Boulder property owners have one phone number, one point of contact, and one company responsible for the outcome from start to finish.
When a pipe bursts, a basement floods, or a storm drives water into your Boulder home or business, the standing water you're looking at is only the beginning of the problem. Call +1-844-499-0972 the moment you discover water in your Boulder property — our dispatcher will guide you through immediate protective steps while our crew is already on the way.
For Boulder 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 Boulder 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 Boulder 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. Our Boulder 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.
Mold is the almost-inevitable consequence of water damage that wasn't addressed quickly or completely — and in Boulder's climate, wet building materials can support mold growth in as little as 24 to 48 hours after initial exposure. HEPA filtration, containment barriers, negative air pressure, and proper PPE are standard on every Boulder mold remediation job — protecting your household members and our crews from exposure to dislodged spores during the removal process.
Professional structural drying in Boulder 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 Boulder jobs prepare documentation packages that include every element a CO 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.

📞 Call +1-844-499-0972 — Boulder Emergency LineWhen water damage hits in Boulder, the decision you make in the first 30 minutes — who you call and how fast they show up — will define the entire scope and cost of your restoration experience.
We're not a call center forwarding your Boulder emergency to a regional contractor — we have crews stationed locally in Boulder, ready to deploy immediately.
In Boulder neighborhoods we know well, our response times are frequently even faster than our stated target.
Our Xactimate-based estimates are formatted the way your CO insurance carrier expects to receive them, which means no disputes and faster claim processing.
Certified technicians apply science-based drying principles that produce better outcomes faster — not gut-feel approaches that leave moisture behind.
Boulder jobs get industrial LGR dehumidifiers, truck-mounted extraction, thermal imaging cameras, and moisture mapping arrays — not residential-grade rental equipment.
We file the claim, deal with the adjuster, and fight for a fair settlement — so you don't have to learn the insurance claims process on top of dealing with a flooded property.
Every Boulder job comes with a written satisfaction guarantee — if the restoration doesn't meet our stated standard, we return and make it right at no additional cost.
Your Boulder job gets a single dedicated project manager — one person you can call, who knows your file, who is accountable for your outcome from first dispatch to final walkthrough.
Our process eliminates the guesswork and the anxiety of not knowing what comes next — because you deserve to know exactly what your restoration team is doing and why at every step.
You receive your crew's estimated arrival time before you hang up, and a direct callback number if anything changes en route.
Our crew arrives at your Boulder property and immediately begins a systematic assessment — identifying every water entry point, mapping moisture migration with detection instruments, and classifying the water category (clean, gray, or black water).
With the scope confirmed and your approval in hand, extraction begins immediately using the highest-capacity equipment appropriate for the situation.
Daily moisture readings are taken, recorded, and shared with you and your insurance adjuster so everyone can see the drying progress in real numbers.
A written remediation report is issued that documents every action taken and every clearance measurement recorded.
We coordinate the reconstruction scope with your insurance carrier's supplement process before work begins, so funding is in place and there are no payment delays.
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.
Our Boulder technicians bring this material-specific knowledge to every assessment and use it to build drying plans that work for your specific property rather than applying a generic template.
Boulder's weather patterns contribute to the types of water damage events we see most frequently here — and our crews are prepared for the specific scenarios that Boulder property owners face more often than those in other markets.
Water damage restoration costs in Boulder 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 Boulder 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. Call +1-844-499-0972 for a free on-site estimate with no obligation to proceed — we'll give you a clear picture of scope and cost before you commit to anything.
If you're a property owner in Boulder who has just discovered water damage — whether it's an active flood or moisture you noticed during an inspection — your best first call is +1-844-499-0972.

These are the experiences of your neighbors in Boulder — unedited, firsthand accounts of working with our local restoration team.
"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 Boulder 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 Boulder 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 Boulder 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."
