Union 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 Union-based Water Damage Repair teams are licensed, certified, and ready around the clock.
Local Union crews on standby — not dispatched from out of the area.
Certified professionals, not unlicensed laborers.
No hidden fees, no last-minute line items.
We build your claim file and deal with your adjuster directly.
Water damage in Union moves on its own timeline, which is why our local dispatch operation stays fully staffed around the clock, every day of the year — so that when the call comes in at 2 a.m., the crew heading to your door is already mobilized.
Every technician who arrives at your Union 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 Union's housing stock.
Our reputation in Union 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.

COS Water Damage Restoration provides comprehensive Water Damage Repair in Union — covering every phase from emergency extraction through mold remediation, structural drying, and full reconstruction, all managed by our local Union crew.
When a pipe bursts, a basement floods, or a storm drives water into your Union 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 Union property — our dispatcher will guide you through immediate protective steps while our crew is already on the way.
We approach every Union 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 Union 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. Whether the loss is a small office suite or an entire floor of a commercial building, COS Water Damage Restoration's Union commercial team has the experience and equipment to handle it.
COS Water Damage Restoration's mold remediation team in Union 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.
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 Union drying crews take measurement seriously and don't sign off on a project until the numbers confirm completion. Your project manager reviews the daily readings with you or provides them by phone or message on request, and reconstruction planning begins only after final readings confirm compliance with drying targets across all affected assemblies.
COS Water Damage Restoration takes the second challenge entirely off your hands — from the first notice of loss through final settlement — so you can focus on your family and your recovery rather than on paperwork, phone calls, and adjuster negotiations. 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.



Our Union crew is on standby — call now and someone is heading to your door in under an hour.
📞 Call +1-844-499-0972 — Union Emergency LineWhen water damage hits in Union, 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.
We're not a call center forwarding your Union emergency to a regional contractor — we have crews stationed locally in Union, ready to deploy immediately.
Speed of response is the single most controllable factor in limiting water damage costs — and we've optimized our Union operation around it.
Our Xactimate-based estimates are formatted the way your WA insurance carrier expects to receive them, which means no disputes and faster claim processing.
Certified technicians apply science-based drying principles that produce better outcomes faster — not gut-feel approaches that leave moisture behind.
Better tools mean faster drying, more thorough moisture removal, and far less risk of mold development or structural damage after the job is complete.
Supplement filing for underpaid claims is part of the service — because we believe your policy should pay what your loss is documented to be.
Every Union 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.
One contact, complete accountability, from start to finish.
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.
You receive your crew's estimated arrival time before you hang up, and a direct callback number if anything changes en route.
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.
Contaminated water scenarios activate full containment protocols — antimicrobial pre-treatment, barrier installation, and regulated disposal procedures to protect your household from cross-contamination.
A calculated drying plan is implemented immediately following extraction — air movers and dehumidifiers placed based on psychrometric data specific to your Union property's materials and conditions.
Antimicrobial treatment is applied to all moisture-exposed surfaces as a standard preventive step — stopping mold colonization before it can take hold in your Union property's structural assemblies.
Our licensed reconstruction team handles all Union rebuilding work — drywall, flooring, painting, trim, and structural repairs — under the same project management as the restoration phase.
COS Water Damage Restoration's Union-based crews bring none of those disadvantages — our technicians know Union, work in Union'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.
Our Union 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.
That local context makes our assessments more accurate, our response timelines more reliable, and our client communication more informed.
Water damage restoration costs in Union 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 Union 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 Union 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 Union, WA property owners who called COS Water Damage Restoration when water threatened their homes and businesses.
"I run a small business in Union 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 Union."
"The burst pipe situation in our Union 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 Union 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."
