COS Water Damage Restoration's Granville-based Water Damage Repair teams are licensed, certified, and ready around the clock.
Positioned in Granville 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 WV insurers.
COS Water Damage Restoration's Granville team isn't a remote dispatch forwarding your call to whoever happens to be available — we maintain a dedicated local operation in Granville 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.
We bring enterprise-grade extraction and drying equipment to every Granville 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 Granville 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.

Every service listed below is available 24/7 in Granville — no wait lists, no "call back during business hours," no sending you to a subcontractor we can't vouch for.
In Granville, 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. Granville'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.
Our residential restoration teams in Granville are experienced across the full range of home types found in the area — older homes with original hardwood and plaster, newer construction with engineered materials and finished basements, and everything in between. Our moisture mapping process identifies every area where water has penetrated — not just what's visible on the surface, but the moisture inside wall assemblies, under flooring systems, and in ceiling cavities — so that the drying plan we build addresses the complete scope of moisture, not just the obvious puddles.
COS Water Damage Restoration's commercial restoration operation in Granville 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. Whether the loss is a small office suite or an entire floor of a commercial building, COS Water Damage Restoration's Granville commercial team has the experience and equipment to handle it.
Mold is the almost-inevitable consequence of water damage that wasn't addressed quickly or completely — and in Granville'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 Granville 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.
COS Water Damage Restoration takes the second challenge entirely off your hands — from the first notice of loss through final settlement — so you can focus on your family and your recovery rather than on paperwork, phone calls, and adjuster negotiations. Our approach to insurance coordination in Granville 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.

Local presence means faster arrival, familiarity with Granville neighborhoods and buildings, and a direct accountability to the community we serve.
Our Granville 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.
Flat-rate pricing means the number on your estimate matches the number on your final invoice, assuming no scope changes.
Your Granville home or business deserves the professionalism that certification represents.
We invest in the equipment that produces the outcomes our Granville customers review five stars for.
Our Granville claim team knows the carriers serving this market, the documentation those carriers require, and how to build a file that moves through underwriting quickly and pays out what you're owed.
We're accountable for our work because our reputation in Granville is built one job at a time, and we take that seriously.
Your Granville 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 call +1-844-499-0972 and a live Granville 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.
Contaminated water scenarios activate full containment protocols — antimicrobial pre-treatment, barrier installation, and regulated disposal procedures to protect your household from cross-contamination.
A calculated drying plan is implemented immediately following extraction — air movers and dehumidifiers placed based on psychrometric data specific to your Granville property's materials and conditions.
Pre-existing or emerging mold growth is addressed by our IICRC-certified remediation specialists with containment, HEPA air scrubbing, material removal, and clearance testing.
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 Granville 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 Granville 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 Granville's plumbing, we approach Granville jobs with an awareness of local conditions that an out-of-area contractor simply can't replicate.
Water damage restoration costs in Granville 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 Granville 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.
Our Granville 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 Granville 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 Granville 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 Granville 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 Granville 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."
