Basement flooding in Toronto: what actually happens
Toronto has a long record of storms that outrun its sewers. On July 8, 2013, more than 100 mm of rain fell in about 90 minutes and the City logged almost 4,800 basement flooding complaints. On July 16, 2024, the city had more than a month of rain in about three hours. Those are the headline events, but ordinary summer thunderstorms and spring thaws flood basements in the city every year.
This site is about basement floods across the city. We pump the water out, remove what cannot be saved, dry the structure to measured readings and rebuild. You get a free assessment, then a written scope and price. The crew that pumps out your basement also strips, dries and rebuilds it, so a single team covers the entire job from the flood to a usable room again.

Learn moreHow we tell the three causes of a basement flood apart
Water enters a Toronto basement in three ways. It comes up the floor drain when the sewer is overloaded. It seeps through walls and floors when the ground is saturated. Or it overflows when a sump pump fails or cannot keep up. Each cause changes the cleanup. Sewer water is contaminated and porous materials must go. Groundwater is cleaner but still carries soil and bacteria. A failed pump is the cause people forget to check.
Your insurer will ask how the water got in, so we note the entry point on the first visit.
What we record for you
- Where the water entered and when it was found
- Moisture readings in each room, repeated until dry
- Photos of the damage and of everything removed
- A list of belongings moved or packed out
- A written scope and price before work proceeds
Why Toronto basements flood differently across the city
The reason a basement floods tells you where to look next. In older central streets, buried creek lines and clay soils can push water through stone foundations after long rain. In postwar neighbourhoods, a combined or overloaded sewer may send water up a floor drain. In the newer suburbs, drainage that works in normal rain can be overwhelmed by sudden downpours, and window wells and grading come into play. Our crew asks which of these fits your street and then verifies it on site.
That is why a single quote over the phone is not possible. The free assessment tells us what the water did, and a written scope and price follow.
Your first hour in a flooded basement
- Do not go downstairs if water is near outlets, the panel or appliances.
- Switch off the circuits you can reach safely, and leave the rest to us.
- Photograph the water level against a wall or stair, with a measuring tape if you have one.
- Carry out items that are dry and light, and leave heavy furniture.
- Leave floor drains alone, and use no water upstairs if the water came up a drain.
- Call us, then call your insurer and write down the claim reference.
