What We Do

Water Damage Restoration Services in San Mateo, CA

Our San Mateo Water Damage Restoration team handles every phase of recovery in-house: no subcontracting, no coordination gaps, no handoff problems.

🚨

Emergency Response & Extraction

The moment your call connects, our San Mateo 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.

📊

Moisture Mapping & Damage Assessment

Every affected assembly is documented with instrument readings before drying begins.

💨

Structural Drying Program

Industrial LGR dehumidifiers and high-velocity air movers are deployed in calculated configurations based on your San Mateo 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.

🧹

Mold Prevention & Remediation

Antimicrobial treatment is applied to all moisture-exposed structural surfaces as a standard preventive step in every San Mateo 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.

📋

Insurance Claim Coordination

Supplement filing for underpaid San Mateo claims is part of the service.

🏠

Full Reconstruction & Rebuild

One company, start to finish.

"Our San Mateo business had a roof-to-slab water event on a Thursday night. By Friday morning COS Water Damage Restoration had extracted everything, staged drying equipment, and given me a documented scope I could hand directly to my adjuster. We were operational again the following week. Truly professional."
