A flood in Grafton doesn't get better by waiting, and the cost of delay is measured in thousands of dollars of preventable damage. COS Water Damage Restoration's Grafton-based Water Damage Repair teams are licensed, certified, and ready around the clock.
Local Grafton crews on standby — not dispatched from out of the area.
Certified professionals, not unlicensed laborers.
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 Grafton'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.
Every technician who arrives at your Grafton 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 Grafton's housing stock.
COS Water Damage Restoration has earned the trust of Grafton 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.

COS Water Damage Restoration provides comprehensive Water Damage Repair in Grafton — covering every phase from emergency extraction through mold remediation, structural drying, and full reconstruction, all managed by our local Grafton crew.
In Grafton, 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. Call +1-844-499-0972 the moment you discover water in your Grafton property — our dispatcher will guide you through immediate protective steps while our crew is already on the way.
For Grafton 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. Commercial jobs in Grafton 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 Grafton'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.
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 Grafton 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.
Grafton 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 Grafton and Grafton, ND 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.

📞 Call +1-844-499-0972 — Grafton Emergency LineWhen water damage hits in Grafton, 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.
When you call COS Water Damage Restoration in Grafton, the crew that shows up actually works here.
Our Grafton dispatch target is 60 minutes or less from your call to a crew at your door — and we hit that target consistently because we're positioned locally, not dispatched from another city.
In Grafton, COS Water Damage Restoration never starts work without providing a written, itemized estimate that you've approved — no exceptions, no gray areas.
Your Grafton home or business deserves the professionalism that certification represents.
Grafton jobs get industrial LGR dehumidifiers, truck-mounted extraction, thermal imaging cameras, and moisture mapping arrays — not residential-grade rental equipment.
Supplement filing for underpaid claims is part of the service — because we believe your policy should pay what your loss is documented to be.
Every Grafton 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.
No being transferred between departments, no explaining your situation to a new person every time you call, no wondering who's responsible.
Here's exactly what happens when you call COS Water Damage Restoration for water damage in Grafton, from the moment the phone rings to the day we hand your property back.
You receive your crew's estimated arrival time before you hang up, and a direct callback number if anything changes en route.
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.
Equipment stays until documented readings confirm completion — not until a certain number of days has passed.
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.
When a restoration company sends a crew to your Grafton property who has never worked in the area, the difference in performance is real — and it shows up in ways that matter: slower navigation to your address, unfamiliarity with local building code requirements that affect how drying and reconstruction are approached, no relationship with local supply vendors that allows materials to be sourced quickly, and no reputation to protect within the community they're serving.
Our Grafton 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.
Whether it's the spring flooding pattern, the summer storm profile, or the winter freeze-thaw cycle that affects Grafton's plumbing, we approach Grafton jobs with an awareness of local conditions that an out-of-area contractor simply can't replicate.
Water damage restoration costs in Grafton 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 Grafton 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.
COS Water Damage Restoration's goal is to make the worst part of dealing with water damage — that initial frantic hour — as manageable as possible, and we start doing that the moment you pick up the phone.

Read what Grafton 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 Grafton 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 Grafton 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 Grafton 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."
