Here's what separates COS Water Damage Restoration's Water Damage Restoration service from every other option in Etna.
Every technician holds active NH contractor licensing and IICRC WRT certification. Full general liability and workers' comp coverage is in force on every Etna job.
Locally staged equipment and crews mean our Etna response time beats out-of-area contractors every time.
We quote in writing before we start. What you approve is what you pay.
Our reputation in Etna is one job at a time. We stand behind every single one.
Our Etna Water Damage Restoration team handles every phase of recovery in-house: no subcontracting, no coordination gaps, no handoff problems.
The moment your call connects, our Etna restoration dispatcher starts building your response. Extraction crews arrive with truck-mounted systems capable of removing high volumes of water rapidly — limiting saturation time and reducing the overall restoration scope.
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 Etna 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 Etna 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 Etna claims is part of the service.
One company, start to finish.


Real person, real dispatch. Call +1-844-499-0972 and your Etna crew is moving before you hang up.
Our Etna 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.
Written satisfaction guarantee on every Etna job.



"After a supply line failure soaked our kitchen and part of the living room, COS Water Damage Restoration was at our Etna 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."
"The insurance side of a water damage claim is overwhelming. COS Water Damage Restoration's Etna team handled everything — filed the first notice, attended the adjuster visit, and got us a fair settlement. I didn't make a single insurance phone call myself."
