COS Water Damage Restoration's Old Westbury team isn't a remote dispatch forwarding your call to whoever happens to be available — we maintain a dedicated local operation in Old Westbury 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 Old Westbury 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.
Our reputation in Old Westbury 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.

Our integrated service model means Old Westbury property owners have one phone number, one point of contact, and one company responsible for the outcome from start to finish.
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. Old Westbury'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 Old Westbury 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 Old Westbury 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 Old Westbury commercial team has the experience and equipment to handle it.
Many Old Westbury 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. 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.
Professional structural drying in Old Westbury is the phase of water damage restoration that most homeowners understand least — and the one that most directly determines whether the restoration holds up long-term or creates ongoing problems. 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.
Our claim coordinators assigned to Old Westbury jobs prepare documentation packages that include every element a NY 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 Old Westbury and Old Westbury, NY 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.

Five-star reviews are earned, not purchased — and they reflect what happens when every technician takes personal pride in the outcome of every job.

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.
Equipment stays until documented readings confirm completion — not until a certain number of days has passed.
Antimicrobial treatment is applied to all moisture-exposed surfaces as a standard preventive step — stopping mold colonization before it can take hold in your Old Westbury 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.
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.
Older Old Westbury homes with original hardwood flooring, plaster walls, and basement moisture histories require different drying strategies than newer builds with engineered hardwood, drywall, and open-plan floor plans that allow air movement differently.
Whether it's the spring flooding pattern, the summer storm profile, or the winter freeze-thaw cycle that affects Old Westbury's plumbing, we approach Old Westbury jobs with an awareness of local conditions that an out-of-area contractor simply can't replicate.
Water damage restoration costs in Old Westbury 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.

These are the experiences of your neighbors in Old Westbury — 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 Old Westbury 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."
"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 Old Westbury."
"Mold found during the renovation of our Old Westbury 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."
