Introduction
A leaky basement is more than a seasonal botherance, it’s a sign that your home’s foundation may be at risk. In Toronto, where weather shifts, aging homes, and dense urban drainage systems are common, dealing with basement leaks is part of homeownership. That’s why thousands trust Canada Waterproofers, the leading basement waterproofing company in the region.
From wet basement repairs and foundation crack repair to full exterior waterproofing solutions, Canada Waterproofers provides comprehensive basement waterproofing services that keep your basement dry, for good.
Why Exterior Waterproofing Important in Toronto
If you’re dealing with a wet basement, your best defense is stopping water before it gets inside. That’s where exterior waterproofing comes in. This process involves sealing foundation walls from the outside using proper waterproofing methods, including drainage systems, membranes, and weeping tile. By using only the best exterior foundation waterproofing products, Canada Waterproofers ensures a long-term solution that strengthens your structural integrity and prevents future basement flooding.
If you live in older Toronto neighborhoods like Scarborough, Mississauga, or North York, your property likely lacks proper moisture protection. That’s why exterior waterproofing Toronto services are so critical, and worth the investment.
Understanding the Cost of Exterior Waterproofing
One of the first questions homeowners ask is: “What’s the exterior waterproofing cost?” The answer depends on your property, foundation depth, and damage extent. On average, exterior waterproofing costs between $80 and $200 per linear foot, while interior waterproofing typically ranges from $70 to $120 per linear foot.
Your basement waterproofing project depends on many factors, soil conditions, access space, and the presence of foundation cracks or existing concrete walls.

The Importance of Interior Drainage Systems
For many homes with finished basements or limited access to foundation walls, interior waterproofing is a practical alternative. It involves the installation of interior drainage systems along the basement floor, connecting to a sump pump that redirects water away from the house.
Our internal waterproofing solutions are ideal for controlling hydrostatic pressure, the force of groundwater pushing through basement walls, without excavation. Whether you’re facing damp basements, musty odors, or water on the basement floor, interior systems offer quick relief and long-term protection.
Why Toronto Neighbourhoods Face Unique Waterproofing Challenges
Homes across Toronto deal with different basement problems—mostly due to soil conditions, weather, and infrastructure age. For example, in Scarborough, the dominant clay-rich soil retains water for long periods, making homes vulnerable to hydrostatic pressure, foundation wall seepage, and even structural damage if exterior waterproofing isn’t in place.
In Etobicoke, proximity to Lake Ontario and naturally high water tables increase the risk of basement flooding, especially during spring thaw and storm events. Meanwhile, North York is home to many mid-century properties with aging infrastructure, meaning older drainage systems, worn concrete walls, and a lack of modern waterproofing systems.
According to the Canada Mortgage and Housing Corporation (CMHC), 60% of Canadian homes will experience some form of water damage in their lifetime—mostly through basement leaks. This makes proper, location-specific basement waterproofing services more than just a precaution—it’s a necessity.

What the Government Says: Basement Flooding is on the Rise
According to the Canada Mortgage and Housing Corporation (CMHC), over 60% of Canadian homes will experience basement flooding or water damage at some point. In Toronto alone, billions have been invested in stormwater infrastructure, yet homeowners are still encouraged to install sump pumps, backwater valves, and take steps like foundation waterproofing to protect their homes.
