Do You Need Basement Waterproofing in Toronto?

With the average age of Toronto homes exceeding 50 years, it is likely that your basement was not built with modern waterproofing techniques that will stand up in today’s climate. Extreme rainfall is only increasing in Toronto, making it even more important to check both older and newer homes for strong defences against flooding and moisture.

If you live in a Victorian, Edwardian or Georgian home throughout the city and you have not updated your basement waterproofing solutions, then it is time to give us a ring!

Signs Of A Wet Basement:

If you notice one or more of the below tell-tale signs, then it is likely you already have moisture present in your basement:

  • Musty, earthy or damp smells in your basement
  • White chalky residue on walls, floors, or ceilings
  • Paint is peeling or bubbling
  • Basement walls are damp or cold to the touch
  • Metal fixtures have turned rusty

Give DGI a call today to book your FREE basement inspection! Our local waterproofing contractors will evaluate your space and create a custom waterproofing plan that tackles your property’s unique struggles.

Toronto’s Local Conditions

Why Waterproofing Toronto Homes Is A Necessity

  • Older Homes: Over 135,000 single and semi-detached homes in Toronto were built before 1946, these rely on older foundations and drainage that are structurally weak against modern floods.
  • Intense Flash Flooding: Due to climate change, Toronto is now frequently experiencing 1-in-100-year storms. In July 2024, a storm dropped nearly 10cm of rain in three hours, instantly overwhelming drainage systems.
  • Financial Risk: The July 2024 flood event resulted in a direct insured loss of $99 million CAD in Southern Ontario, demonstrating the massive financial exposure to property owners.
  • Hydrostatic Pressure from Clay: Toronto’s underlying geology is dominated by low-permeability glacial till and high-plasticity clay, which traps water and creates intense pressure against basement walls, leading to cracks and leaks.
  • Rising Claim Costs: The average claim size from the 2024 flood was approximately $10,000 higher than the 2013 event, a trend showing that damage costs are rapidly escalating due to inflation and weather intensity.
  • Underinsurance Danger: Only 10% to 15% of households carry overland flood insurance, leaving the vast majority of homeowners responsible for 100% of repair costs after a major flood.

The time to protect your investment is now, before the next storm hits. Call and book your professional waterproofing assessment today.
