How to Reduce the Risk of Basement Flooding During Heavy Rain

Manage roof water

• Clean eavestroughs in spring and fall
• Extend downspouts at least 2 metres from the foundation where permitted
• Direct water toward lawns or gardens, not driveways or neighbours

Check grading

Soil around the foundation should slope away from the house. Settled areas next to the foundation can be built up with soil.

Maintain your sump pump

Test the pump by pouring water into the pit, check that the discharge line is clear and consider a battery backup.

Consider a backwater valve

A backwater valve can help reduce the risk of sewer backup during surcharge events. Installation typically requires a permit and a licensed plumber.

Store items wisely

Keep valuables off basement floors in plastic bins on shelving.
