What should I do first when my basement floods?

Turn off electricity to the flooded area if it is safe to reach the panel, avoid walking through standing water near outlets, and call a drainage or water damage company right away to start extraction.

Why does my basement flood every time it rains heavily?

Common causes are a failing or undersized sump pump, clogged or damaged weeping tile, poor grading around the foundation, or downspouts dumping water too close to the house.

Can a French drain stop repeat flooding?

In many cases yes, especially when combined with fixing grading and downspouts, but a contractor needs to see where the water is actually entering before recommending it.

Emergency basement flooding cleanup

Heavy rain, a failed sump pump or a backed-up sewer line can put several inches of water in a Toronto basement within an hour. This page covers the urgent cleanup plus the drainage fix that stops the next storm from doing the same thing.

Same-day pumping and water extraction from finished or unfinished basements
Inspection of the sump pump, weeping tile and window wells to find the entry point
Temporary measures (pumps, sandbagging) while a permanent drainage fix is scheduled
Grading, downspout extensions or French drain repair to address the cause
Coordination with a water damage restoration crew if flooring or drywall needs replacing

Ask whether the company distinguishes between a one-time cleanup and a lasting drainage repair. A crew that only pumps out water without addressing the weeping tile or grade around your foundation will likely see you call again during the next big rain.

What it costs

Emergency pump-outs are priced by how much water and how large the area is, often as a callout plus hourly extraction charge. The drainage repair that follows (regrading, downspout work, weeping tile repair) is a separate, larger cost that depends on how much excavation is involved. Getting both quoted separately helps you see what is urgent versus what can be scheduled.
