A flood in Ellendale 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 Ellendale-based Water Damage Repair teams are on standby 24/7 with equipment staged and crews briefed.
Positioned in Ellendale for fast local response every time.
Certified professionals, not unlicensed laborers.
No hidden fees, no last-minute line items.
Works with all major ND insurers.
We've handled everything from flash-flood basement extractions in Ellendale'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 Ellendale 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 Ellendale's housing stock.
COS Water Damage Restoration has earned the trust of Ellendale 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 Ellendale — covering every phase from emergency extraction through mold remediation, structural drying, and full reconstruction, all managed by our local Ellendale crew.
When a pipe bursts, a basement floods, or a storm drives water into your Ellendale 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.
Our residential restoration teams in Ellendale 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. 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 Ellendale 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.
Many Ellendale 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 Ellendale mold remediation job — protecting your household members and our crews from exposure to dislodged spores during the removal process.
Professional structural drying in Ellendale 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 Ellendale property — not a one-size-fits-all equipment drop.
Ellendale 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 Ellendale and Ellendale, 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.

COS Water Damage Restoration's Ellendale-based crews bring none of those disadvantages — our technicians know Ellendale, work in Ellendale's neighborhoods regularly, understand the construction patterns and material choices common in different parts of the city, and are invested in the reputation we've built here job by job.
Older Ellendale 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.
Ellendale'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 Ellendale property owners face more often than those in other markets.
Water damage restoration costs in Ellendale 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 Ellendale 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.

These are the experiences of your neighbors in Ellendale — unedited, firsthand accounts of working with our local restoration team.
"I run a small business in Ellendale 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 Ellendale."
"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 Ellendale."
"Mold found during the renovation of our Ellendale 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."
