When water damage hits your home or business in Addison, 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 Addison-based Water Damage Repair teams are licensed, certified, and ready around the clock.
Local Addison crews on standby — not dispatched from out of the area.
Every technician holds current WRT certification — the industry standard.
No hidden fees, no last-minute line items.
We build your claim file and deal with your adjuster directly.
COS Water Damage Restoration's Addison team isn't a remote dispatch forwarding your call to whoever happens to be available — we maintain a dedicated local operation in Addison 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 Addison 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.
If you've already experienced water damage in Addison and need someone to respond right now, call +1-844-499-0972 — our local crew is ready.

COS Water Damage Restoration provides comprehensive Water Damage Repair in Addison — covering every phase from emergency extraction through mold remediation, structural drying, and full reconstruction, all managed by our local Addison crew.
Our truck-mounted extraction systems can pull high volumes of water in a fraction of the time it would take with consumer-grade equipment — getting the visible water out fast while our moisture detection team maps the water you can't see yet. Addison'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 Addison 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.
Water damage to a commercial property in Addison isn't just a property issue — it's a business interruption event that starts costing revenue from the moment the damage begins. Whether the loss is a small office suite or an entire floor of a commercial building, COS Water Damage Restoration's Addison 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 Addison'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 Addison drying crews take measurement seriously and don't sign off on a project until the numbers confirm completion. 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 Addison property — not a one-size-fits-all equipment drop.
Our claim coordinators assigned to Addison jobs prepare documentation packages that include every element a IL 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. Our approach to insurance coordination in Addison 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.



Our Addison crew is on standby — call now and someone is heading to your door in under an hour.
📞 Call +1-844-499-0972 — Addison Emergency LineWhen water damage hits in Addison, the decision you make in the first 30 minutes — who you call and how fast they show up — will define the entire scope and cost of your restoration experience.
Local presence means faster arrival, familiarity with Addison neighborhoods and buildings, and a direct accountability to the community we serve.
In Addison neighborhoods we know well, our response times are frequently even faster than our stated target.
In Addison, COS Water Damage Restoration never starts work without providing a written, itemized estimate that you've approved — no exceptions, no gray areas.
Your Addison home or business deserves the professionalism that certification represents.
We invest in the equipment that produces the outcomes our Addison 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 Addison 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 Addison crew, and dispatches them immediately — all within the first few minutes of your call.
Our crew arrives at your Addison property and immediately begins a systematic assessment — identifying every water entry point, mapping moisture migration with detection instruments, and classifying the water category (clean, gray, or black water).
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.
A written remediation report is issued that documents every action taken and every clearance measurement recorded.
Our licensed reconstruction team handles all Addison rebuilding work — drywall, flooring, painting, trim, and structural repairs — under the same project management as the restoration phase.
COS Water Damage Restoration's Addison-based crews bring none of those disadvantages — our technicians know Addison, work in Addison'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.
Addison'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 Addison's plumbing, we approach Addison jobs with an awareness of local conditions that an out-of-area contractor simply can't replicate.
Water damage restoration costs in Addison 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 Addison 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 Addison — unedited, firsthand accounts of working with our local restoration team.
"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 Addison 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 Addison 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."
"I had a fear that calling a restoration company would mean getting upsold on everything and being pressured into expensive services I didn't need. COS Water Damage Restoration was the complete opposite of that experience. The technician explained the moisture readings to me at each sensor point, showed me why certain materials needed to be addressed and others could be left in place, and gave me an honest assessment of what the insurance would likely cover versus what might be out of pocket. No pressure, no inflated scope — just honest professional advice and excellent execution. My Addison neighbors have my standing recommendation for them."
