We've handled everything from flash-flood basement extractions in Long Beach'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.
We bring enterprise-grade extraction and drying equipment to every Long Beach 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.

Every service listed below is available 24/7 in Long Beach — no wait lists, no "call back during business hours," no sending you to a subcontractor we can't vouch for.
When a pipe bursts, a basement floods, or a storm drives water into your Long Beach home or business, the standing water you're looking at is only the beginning of the problem. Long Beach'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.
We approach every Long Beach 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. Our moisture mapping process identifies every area where water has penetrated — not just what's visible on the surface, but the moisture inside wall assemblies, under flooring systems, and in ceiling cavities — so that the drying plan we build addresses the complete scope of moisture, not just the obvious puddles.
COS Water Damage Restoration's commercial restoration operation in Long Beach 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 Long Beach 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 Long Beach 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 Long Beach mold remediation job — protecting your household members and our crews from exposure to dislodged spores during the removal process.
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. 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.
Long Beach 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. 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.

You call +1-844-499-0972 and a live Long Beach dispatcher answers — no voicemail, no call tree, no waiting on hold during your emergency.
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.
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 Beach 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 Beach 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.
Our Long Beach 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.
Whether it's the spring flooding pattern, the summer storm profile, or the winter freeze-thaw cycle that affects Long Beach's plumbing, we approach Long Beach jobs with an awareness of local conditions that an out-of-area contractor simply can't replicate.
Water damage restoration costs in Long Beach 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 Beach 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.

Real reviews from Long Beach, WA property owners who called COS Water Damage Restoration when water threatened their homes and businesses.
"I run a small business in Long Beach 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 Beach."
"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 Long Beach."
"Mold found during the renovation of our Long Beach 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."
