Here's what separates COS Water Damage Restoration's Water Damage Restoration service from every other option in Lexington.
Every technician holds active MA contractor licensing and IICRC WRT certification. Full general liability and workers' comp coverage is in force on every Lexington job.
Our Lexington-based crews target 60-minute on-site response. We don't route your emergency through a regional call center — local dispatch means faster arrival and better outcome.
Xactimate-based scope of work reviewed with you before any equipment is placed. The estimate you approve is the invoice you receive — no hidden line items, no after-the-fact surprises.
Our reputation in Lexington is one job at a time. We stand behind every single one.
Our Lexington Water Damage Restoration team handles every phase of recovery in-house: no subcontracting, no coordination gaps, no handoff problems.
Speed at this phase directly determines how much is salvageable. Our Lexington crews don't slow down on the way to your property.
Every affected assembly is documented with instrument readings before drying begins.
Industrial LGR dehumidifiers and high-velocity air movers are deployed in calculated configurations based on your Lexington property's materials, square footage, and psychrometric conditions. Daily readings at fixed sensor points document the drying progression until all assemblies reach target equilibrium moisture content.
Antimicrobial treatment is applied to all moisture-exposed structural surfaces as a standard preventive step in every Lexington Water Damage Restoration job. Where mold growth is identified, IICRC S520-compliant remediation — with HEPA containment, negative air pressure, and clearance testing — is performed before reconstruction begins.
Supplement filing for underpaid Lexington claims is part of the service.
When drying is confirmed complete, our licensed Lexington reconstruction team handles all rebuild work — drywall, flooring, painting, trim, structural framing — under the same project manager who ran the restoration phase. No handoff to an unknown subcontractor, no coordination gap, no restart of the communication process.


Call +1-844-499-0972 any time — a live Lexington dispatcher answers immediately, gathers the details, and deploys the nearest crew. No voicemail, no automated queue, no call-back-tomorrow policy.
Our Lexington crew targets on-site arrival in 60 minutes or less, staging extraction equipment and containment supplies during transit so they're productive the moment they arrive.
No work starts without your written approval of the scope and cost.
Extraction, drying, remediation, and reconstruction proceed under daily monitoring and documented progress reporting. The job isn't complete until final moisture readings confirm success and you've conducted the walkthrough with your project manager.



"After a supply line failure soaked our kitchen and part of the living room, COS Water Damage Restoration was at our Lexington home in under an hour. The crew's moisture mapping caught wet wall cavity areas I never would have known about. Five days of drying, a perfectly documented insurance file, and zero mold issues. Exactly what you want from a restoration company."
"I was terrified the hardwood floors in our Lexington home were gone after the flooding. The COS Water Damage Restoration crew brought in mat drying systems and dried them in place — saved us thousands versus replacement. The project manager called every morning with readings. Outstanding."
