Spring thaw & heavy rain: keeping water out of the basement

Most basement leaks happen when snow melts fast or it rains for days. Here is how to get ahead of it.

Point downspouts away

Extend downspouts at least 1–2 metres from the foundation.

Soil should slope away from the house. Low spots near the wall collect water.

Pour a bucket of water into the pit — the pump should start on its own. Consider a battery backup.

Leaves and ice in window wells and floor drains send water inside.

Damp spots, white residue on walls and a musty smell mean water is getting in.

Is basement flooding covered by insurance?

Overland flooding and sewer back-up often need extra coverage. Check that your policy includes them.

When should I call a pro?

If water comes in more than once, or you see cracks or mould, get a waterproofing quote.
