When water damage hits your home or business in Long Lake, you need a local crew that can actually show up fast — not a call center routing your emergency to a contractor two hours away. COS Water Damage Restoration's Long Lake-based Water Damage Repair teams are on standby 24/7 with equipment staged and crews briefed.
Positioned in Long Lake for fast local response every time.
Certified professionals, not unlicensed laborers.
Written estimate in your hands before any work begins.
Works with all major MN insurers.
COS Water Damage Restoration's Long Lake team isn't a remote dispatch forwarding your call to whoever happens to be available — we maintain a dedicated local operation in Long Lake 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 Long Lake 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 Long Lake 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 Long Lake — covering every phase from emergency extraction through mold remediation, structural drying, and full reconstruction, all managed by our local Long Lake crew.
In Long Lake, 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. 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.
We approach every Long Lake 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. For Long Lake 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.
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 Long Lake 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.
COS Water Damage Restoration's mold remediation team in Long Lake follows IICRC S520 protocols — the industry standard for safe and effective mold removal — and documents every step of the process so you have a verifiable record of what was found, what was done, and what clearance testing confirmed. 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.
The goal of structural drying isn't just to make the air feel dryer or to run fans for a few days — it's to return every material in the affected area to its documented equilibrium moisture content, verified by calibrated instruments, before any reconstruction begins. 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 Long Lake property — not a one-size-fits-all equipment drop.
Our claim coordinators assigned to Long Lake jobs prepare documentation packages that include every element a MN 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. We've worked with every major insurer serving Long Lake and Long Lake, MN 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 — Long Lake Emergency LineThere are several restoration companies that claim to serve Long Lake — here's why COS Water Damage Restoration consistently earns the call, the five-star review, and the referral.

One contact, complete accountability, from start to finish.
Every Water Damage Repair job in Long Lake follows the same structured process — one we've refined over thousands of local jobs to be as fast, thorough, and transparent as possible.
Your dispatcher gathers the essential information, identifies the closest available Long Lake crew, and dispatches them immediately — all within the first few minutes of your call.
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.
Daily moisture readings are taken, recorded, and shared with you and your insurance adjuster so everyone can see the drying progress in real numbers.
Antimicrobial treatment is applied to all moisture-exposed surfaces as a standard preventive step — stopping mold colonization before it can take hold in your Long Lake property's structural assemblies.
The final walkthrough is conducted with you personally, confirming satisfaction with every element before we close out the job and hand you your warranty documentation.
When a restoration company sends a crew to your Long Lake 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.
Long Lake's mix of housing stock — from older historic homes to newer construction developments — presents a range of material and structural challenges that our crews encounter regularly.
Whether it's the spring flooding pattern, the summer storm profile, or the winter freeze-thaw cycle that affects Long Lake's plumbing, we approach Long Lake jobs with an awareness of local conditions that an out-of-area contractor simply can't replicate.
Water damage restoration costs in Long Lake 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 Long Lake 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 Long Lake 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.

Real reviews from Long Lake, MN property owners who called COS Water Damage Restoration when water threatened their homes and businesses.
"I run a small business in Long Lake 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 Long Lake."
"The burst pipe situation in our Long Lake 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 Long Lake 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."
