Water Damage Repair Toronto, Ontario

6 materials account for most water damage repair work in Toronto homes.

• Drywall: Absorbs water within minutes. Drywall saturated beyond 1% moisture content requires full replacement. Cost: $8 to $15 CAD per square foot installed
• Subfloor (plywood/OSB): Swells and delaminates when wet. Subfloor exceeding 19% moisture on a pin-type meter requires replacement. Cost: $10 to $20 CAD per square foot
• Hardwood flooring: Cups, crowns, and buckles when moisture enters from below. Salvageable if dried within 48 hours. Replacement cost: $12 to $25 CAD per square foot
• Framing lumber: Structural studs and joists require inspection when wet for more than 72 hours. Mold and rot compromise load-bearing capacity
• Insulation: Fiberglass batts lose R-value when wet. Spray foam resists water but traps moisture behind it. All wet insulation requires removal
• Ceiling drywall: Water pooling above ceiling drywall causes sagging and collapse risk. Weight of trapped water reaches 4 kg per square metre

Water Damage Restoration Toronto LLC tests every material with calibrated moisture meters before determining repair versus replacement.

$2,500 to $12,000 CAD covers structural water damage repair for most Toronto residential projects. Water damage repair is separate from water extraction and drying. The repair phase begins only after moisture readings confirm the structure has dried to below 15% moisture content. Water Damage Restoration Toronto LLC handles the full sequence from extraction through final repair.

Replace when moisture content exceeds 1% or when the drywall has been wet for more than 48 hours.

Drywall is a porous material that wicks water rapidly through its gypsum core. A single sheet of 12.7mm drywall absorbs up to 1 litre of water before showing visible staining. By the time stains appear, the paper facing has already begun supporting mold growth.

Patch repairs work only when the wet area is smaller than 30 cm by 30 cm and the drywall dried within 24 hours. Larger areas require full sheet replacement to meet Ontario Building Code moisture protection standards. Water Damage Restoration Toronto LLC cuts test openings to inspect cavity conditions before recommending repair versus replacement.
