Exeter 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 Exeter-based Water Damage Repair teams are licensed, certified, and ready around the clock.
Local Exeter crews on standby — not dispatched from out of the area.
Every technician holds current WRT certification — the industry standard.
Written estimate in your hands before any work begins.
We build your claim file and deal with your adjuster directly.
We've handled everything from flash-flood basement extractions in Exeter'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 Exeter 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 Exeter's housing stock.
Our reputation in Exeter 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 Exeter 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 Exeter 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 Exeter property — our dispatcher will guide you through immediate protective steps while our crew is already on the way.
We approach every Exeter 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. 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.
Water damage to a commercial property in Exeter isn't just a property issue — it's a business interruption event that starts costing revenue from the moment the damage begins. Our Exeter 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 Exeter 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. HEPA filtration, containment barriers, negative air pressure, and proper PPE are standard on every Exeter mold remediation job — protecting your household members and our crews from exposure to dislodged spores during the removal process.
Professional structural drying in Exeter 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. We deploy industrial LGR dehumidifiers and high-velocity air movers in a calculated configuration based on the square footage, material types, and psychrometric conditions specific to your Exeter property — not a one-size-fits-all equipment drop.
Exeter 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. 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.



Don't wait to call — our Exeter emergency line is live 24/7 and help is closer than you think.
📞 Call +1-844-499-0972 — Exeter Emergency LineThere are several restoration companies that claim to serve Exeter — here's why COS Water Damage Restoration consistently earns the call, the five-star review, and the referral.
We're not a call center forwarding your Exeter emergency to a regional contractor — we have crews stationed locally in Exeter, ready to deploy immediately.
In Exeter neighborhoods we know well, our response times are frequently even faster than our stated target.
Our Xactimate-based estimates are formatted the way your CA insurance carrier expects to receive them, which means no disputes and faster claim processing.
Your Exeter home or business deserves the professionalism that certification represents.
Better tools mean faster drying, more thorough moisture removal, and far less risk of mold development or structural damage after the job is complete.
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.
Five-star reviews are earned, not purchased — and they reflect what happens when every technician takes personal pride in the outcome of every job.
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 Exeter, 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.
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.
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 Exeter 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.
Older Exeter 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.
Whether it's the spring flooding pattern, the summer storm profile, or the winter freeze-thaw cycle that affects Exeter's plumbing, we approach Exeter jobs with an awareness of local conditions that an out-of-area contractor simply can't replicate.
Water damage restoration costs in Exeter 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 Exeter 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.

Real reviews from Exeter, CA property owners who called COS Water Damage Restoration when water threatened their homes and businesses.
"I run a small business in Exeter 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 Exeter."
"After storm water came through our basement window well during a major rain event, I was at a loss. I had an inch of standing water across the whole basement and no idea who to call. A neighbor recommended COS Water Damage Restoration and I'm glad she did. The crew arrived quickly, immediately identified that the water had already gotten under the vinyl plank flooring, and explained everything they were going to do before they started. The drying took a week — they checked in every single day — and when it was done the insurance settled the claim at the full documented amount. I've since recommended COS Water Damage Restoration to three other people in Exeter."
"Mold found during the renovation of our Exeter 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."
