Cleaning After Water Damage in Ontario
Ontario homes face water damage from multiple sources — spring flooding, burst pipes in winter freeze-thaw cycles, appliance leaks (dishwashers, washing machines, water heaters), and storm water intrusion through foundation cracks or poor drainage. The cleaning and remediation approach after water damage has a critical time component: the window before mould begins to establish is 24–48 hours after water exposure, which means fast action directly affects the scope and cost of the remediation.
Immediate Steps (First 24 Hours)
- Stop the source: Shut off water at the main if a pipe is the source; don't re-enter if structural flooding is uncertain
- Remove standing water: Wet-dry vacuum, mop, or professional water extraction — get water off surfaces as fast as possible
- Air movement and dehumidification: Open windows if outdoor conditions allow, run fans and dehumidifiers continuously — the goal is drying, not just removal of visible water
- Remove wet materials: Wet drywall, insulation, carpet underpad, and wood flooring that remain wet for more than 24 hours will require replacement rather than restoration
Cleaning After Drying
Once affected areas are fully dried (moisture meters confirm complete drying): clean all affected hard surfaces with a disinfectant appropriate for the type of water involved (clean water from a pipe requires standard disinfection; grey or black water from sewage or outdoor flooding requires much more aggressive biocidal treatment and typically professional remediation). Check all remaining drywall, wood framing, and surfaces for any developing mould — early mould can be cleaned; established mould colonies may require professional remediation.
Insurance Documentation
Document everything before, during, and after cleaning for insurance purposes — photos and videos of the damage extent before any cleanup begins. Ontario home insurance typically covers sudden and accidental water damage from burst pipes but not gradual leaks or basement flooding from groundwater intrusion without specific overland flooding coverage.
