Keep your basement flood free

Basements can flood for many reasons. #CityofTO is working hard to make improvements. Here’s what you can do help flood-proof your home:

There are a number of reasons why basements flood, including:

  • When stormwater or ground water seeps into the home (drainage failure) due to:
    • A crack or leak in your home’s foundation, basement walls, or basement windows or door
    • Poor lot grading or drainage
    • Failure of the weeping tile system (foundation drains)
    • Failure of a sump pump (in some homes) used to pump weeping tile water
    • Overflowing eavestroughs
    • Leaking or plugged downspouts
  • A sewer back-up caused by a blocked or overwhelmed sewer pipe.
    • Blockages are typically caused by items that are incorrectly flushed or poured down the drain. Tree roots and broken or cracked sewer pipes can also cause blockages.
    • Overwhelmed sewer pipes can happen during extreme rain. If the sewers fill beyond capacity, the water will travel backward in the sewer pipe and into the home.
