Common Causes of Flooding in Toronto

Knowing where the water came from helps determine the right restoration response.

Burst Pipes

Broken supply lines can release water quickly and affect walls, floors, ceilings and contents.

Frozen Pipes

Freezing can damage plumbing and lead to water release when a pipe fails or thaws.

Heavy Rainfall

Stormwater can overwhelm drainage and enter lower levels through vulnerable points around the property.

Sump Pump Failure

A failed pump can leave a basement exposed to groundwater and stormwater during wet conditions.

Sewer Backups

Blocked or overwhelmed sewer systems can force contaminated water into lower levels.

Foundation Leaks

Foundation cracks and drainage problems can allow water to enter through basement walls and floors.

Water Heater Leaks

A failed water heater can release a significant amount of water into a utility area or basement.

Appliance Failures

Washing machines, dishwashers and other appliances can create sudden indoor water damage.

What Happens After the Cause Is Identified?

The source of the flooding helps determine the response. Standing water may require water extraction, basement flooding may require basement cleanup, and contaminated water may require sewage backup cleanup. Once water is removed, structural drying helps address moisture that remains in building materials. For the complete response, see flood damage restoration in Toronto.

What to Do When Your Property Floods
