Local Lewiston crews on standby — not dispatched from out of the area.
Certified professionals, not unlicensed laborers.

COS Water Damage Restoration's Lewiston team isn't a remote dispatch forwarding your call to whoever happens to be available — we maintain a dedicated local operation in Lewiston 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.
Our Lewiston crew lead coordinates directly with your insurance carrier from the moment we arrive on site — building the documentation package, scheduling the adjuster walkthrough, and following up on open claim items until your settlement is confirmed and you can move forward with reconstruction.
If you've already experienced water damage in Lewiston and need someone to respond right now, call +1-844-499-0972 — our local crew is ready.

Every service listed below is available 24/7 in Lewiston — no wait lists, no "call back during business hours," no sending you to a subcontractor we can't vouch for.
In Lewiston, 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. Lewiston'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 Lewiston 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.
COS Water Damage Restoration's commercial restoration operation in Lewiston 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. Commercial jobs in Lewiston 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 Lewiston's climate, wet building materials can support mold growth in as little as 24 to 48 hours after initial exposure. We never treat mold as a surface problem or attempt to cover it with encapsulants when removal is required — our remediation approach is based on assessment of the affected material and what the manufacturer and IICRC standards recommend for each scenario.
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 Lewiston drying crews take measurement seriously and don't sign off on a project until the numbers confirm completion. Daily moisture readings are taken at consistent sensor points throughout the drying cycle and recorded in a written log that documents the progress of drying over time — useful for your insurance file and for your own records.
Lewiston 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. Our approach to insurance coordination in Lewiston 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 Lewiston neighborhoods and buildings, and a direct accountability to the community we serve.
In Lewiston neighborhoods we know well, our response times are frequently even faster than our stated target.
In Lewiston, COS Water Damage Restoration never starts work without providing a written, itemized estimate that you've approved — no exceptions, no gray areas.
Your Lewiston home or business deserves the professionalism that certification represents.
We invest in the equipment that produces the outcomes our Lewiston customers review five stars for.
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.
Every Lewiston 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.
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.
Your dispatcher gathers the essential information, identifies the closest available Lewiston crew, and dispatches them immediately — all within the first few minutes of your call.
Thermal imaging cameras reveal moisture in wall assemblies and under flooring that isn't yet visible on the surface — giving us a complete picture of the damage before we build the response plan.
With the scope confirmed and your approval in hand, extraction begins immediately using the highest-capacity equipment appropriate for the situation.
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.
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.
That local familiarity translates into faster arrival, fewer logistical delays, better-informed scope assessments, and the kind of personal accountability that comes from knowing your work might be reviewed by someone who lives down the street.
Our Lewiston 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.
Lewiston'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 Lewiston property owners face more often than those in other markets.
Water damage restoration costs in Lewiston 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.

Read what Lewiston 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 Lewiston 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 Lewiston 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 Lewiston 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."
