Flood Damage Restoration Toronto LLC provides IICRC S500-certified structural drying for flood-damaged properties across Toronto, Ontario. Mold begins colonizing wet building materials within 24 to 48 hours — making professional structural drying the critical step between water extraction and full recovery.
What Building Materials Require Structural Drying After a Flood?
- Drywall: Absorbs water to a height of 30 to 60 cm above the visible waterline through capillary action
- Hardwood flooring: Swells, cups, and delaminates when moisture content exceeds 16% — permanent damage occurs above 20%
- Concrete subfloors: Retain moisture for weeks after surface water is removed, requiring specialized low-grain-refrigerant dehumidification
- Wall cavity insulation: Fibreglass and cellulose insulation hold 10 to 20 times their weight in water and resist air-drying alone
- Structural framing: Dimensional lumber swells and warps above 19% moisture content, compromising load-bearing capacity per Ontario Building Code Section 9.14
- Subfloor plywood: OSB and plywood delaminate permanently when moisture content remains above 18% for more than 72 hours

Is Structural Drying Necessary if the Area Looks Dry?
The IICRC S500 standard requires structural drying until all materials test below the dry standard — not until surfaces feel dry to the touch. Toronto homes dried without professional monitoring develop mold in 3 out of 4 cases within 30 days. Insurance companies in Ontario increasingly deny secondary mold claims when the original water damage lacked documented professional drying. Flood Damage Restoration Toronto LLC provides moisture logs with every project for insurance compliance.
