Our Basement Waterproofing
Not sure where the water is coming from? Choose the option below that best matches what you’re seeing — we’ll confirm the cause during your inspection.
Wet Basement Solutions
If water is leaking into your basement, fast action matters. We identify the source and install proven waterproofing solutions to stop active leaks and keep your basement dry.
Foundation Repair
Cracks in your foundation can allow water in and weaken your home over time. We repair foundation cracks and structural issues to restore stability and prevent further damage.
Property Protection
If water is entering your basement, fixing one spot isn’t enough. We manage groundwater and drainage at the foundation to stop leaks, control moisture, and protect your home from recurring water damage.
Our Waterproofing Services in Toronto
We provide complete basement waterproofing and foundation repair across Toronto, with a strong focus on East York, Leslieville, and Scarborough—areas where aging homes, porous block foundations, and high groundwater often lead to leaks and structural issues.
