Cleaning After Water Damage in Ontario
Ontario experiences significant water damage events — spring basement flooding when the frost melts, ice damming on roofs during freeze-thaw cycles, burst pipes during extreme cold events, and the occasional major storm event that overwhelms older storm sewer systems. Here's the framework for cleaning after water damage.
Immediate Priority: Remove Standing Water
The priority immediately after water intrusion is water removal, not cleaning. Standing water needs to come out within 24–48 hours to prevent serious mould growth. For basement flooding, this typically means a wet-dry vacuum, submersible pump, or calling a professional restoration company.
Mould Risk Timeline in Ontario
In Ontario homes during warm months (May–October), mould can begin growing within 24–48 hours of a water event in the right conditions — wet drywall, subfloor, or carpet. In winter, the colder temperatures slow this, but heated Ontario interiors still provide enough warmth for mould growth. Professional water damage restoration follows a 24–48 hour response window as standard.
What Regular Professional Cleaning Covers
Standard professional house cleaning is not the right tool for post-water-damage situations. Water damage restoration requires:
- Industrial dehumidifiers and air movers to reduce moisture in building materials
- Moisture meters to determine drywall and subfloor moisture content
- Potentially drywall removal if moisture readings are too high (wet drywall is a mould substrate)
- Antimicrobial treatment of affected surfaces
This is restoration, not regular cleaning. Contact your home insurance provider for water damage events that exceed simple cleanup — most Ontario home insurance policies cover sudden and accidental water damage.
