How to Prevent Basement Flooding During Heavy Rain

Manage water outside

• Clean eavestroughs and downspouts each spring and fall
• Extend downspouts at least two metres from the foundation
• Make sure soil slopes away from the house
• Keep window well drains clear of leaves

Maintain your sump pump

Test it by pouring water into the pit. Consider a battery backup for outages, and make sure the discharge line isn't blocked or frozen.

Protect against sewer backup

A backwater valve can prevent sewage from flowing back into your basement. The City of Hamilton has offered programs related to protective plumbing; check the city's website for current details.

Store smart

Keep valuables and documents off the basement floor in sealed plastic bins, and avoid storing important items directly against exterior walls.

Review your insurance

Sewer backup and overland flood coverage are often optional add-ons. Talk to your broker before you need it.
