What We Do

Water Damage Restoration Services in Markham, IL

COS Water Damage Restoration's Water Damage Restoration service in Markham covers the complete recovery process — from the first emergency response through mold prevention, structural drying, and full rebuild.

🚨

Emergency Response & Extraction

Speed at this phase directly determines how much is salvageable. Our Markham crews don't slow down on the way to your property.

📊

Moisture Mapping & Damage Assessment

Thermal imaging cameras and calibrated moisture meters map the full extent of water migration in your Markham property — identifying affected wall cavities, subfloor assemblies, and ceiling materials that aren't visible on the surface. A complete damage picture drives a more accurate scope and a faster insurance claim.

💨

Structural Drying Program

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

Our Markham claim coordinators build your documentation file from day one: structured photo evidence, moisture data logs, equipment placement records, and an Xactimate scope of work that matches your carrier's estimating platform. We file, communicate with your adjuster, and follow the claim through to settlement so you don't have to.

🏠

Full Reconstruction & Rebuild

One company, start to finish.
