Flood Damage Restoration Richmondhill LLC repairs flood-damaged walls and drywall across Richmond Hill. Water-damaged drywall carries a $35.23 CPC because property owners urgently search for professional repair -- drywall absorbs water like a sponge and harbours mold within 24 to 48 hours.
What Wall Damage Does Flooding Cause in Richmond Hill Homes?
- Drywall saturation and swelling: Standard drywall absorbs water up to 1 metre above the waterline through capillary action. Saturated drywall loses structural integrity within hours.
- Mold colonization in wall cavities: Hidden moisture behind intact-looking drywall breeds mold within 24 to 48 hours. Infrared cameras detect wet cavities invisible to the eye.
- Insulation collapse: Fibreglass batt insulation absorbs water and compresses, losing 100% of R-value. Wet insulation must be replaced.
- Electrical wiring corrosion: Flood water contacts wiring, outlets, and junction boxes inside wall cavities. The Electrical Safety Authority of Ontario requires inspection before reconnection.
- Baseboard and trim warping: MDF baseboards swell irreversibly. Solid wood trim dries successfully in 80% of cases.
- Paint and texture delamination: Latex paint blisters and peels from saturated drywall. Walls require full re-priming after drying.

Is Flood-Damaged Drywall Always Replaced or Can It Be Dried?
Drywall exposed to Category 1 (clean water) for under 24 hours sometimes dries successfully if professional dehumidifiers are deployed immediately. Category 2 and Category 3 water always requires drywall removal regardless of exposure time. Contaminated drywall cannot be sanitized.
