Our Professional Basement Waterproofing & Sealing Services in Toronto

Interior Waterproofing

If water has already entered your basement, we install interior drainage systems, sump pumps, and vapor barriers to effectively manage moisture and prevent further damage.

Exterior Waterproofing

Safeguard your foundation from the outside in. Exterior waterproofing creates a solid barrier that blocks water before it reaches your foundation, ensuring your basement stays dry through every storm.

Foundation Crack Repair

Cracks in your foundation can lead to serious leaks and structural issues. Our team expertly seals foundation cracks, preventing water from seeping in and compromising your home’s stability.

Sump Pump Installation

A sump pump is crucial for flood prevention, especially during heavy rainfall and rapid snowmelt. We install high-efficiency sump pumps to keep your basement dry and protected year-round.

Window Well Installation

Properly installed window wells prevent water from accumulating around basement windows, reducing the risk of leaks and water damage.

Window Well Installation

Weeping tiles help redirect excess groundwater away from your foundation, reducing hydrostatic pressure and preventing basement leaks. Our modern systems provide long-term drainage solutions.

Crawl Space Encapsulation

A damp crawl space can lead to mold, poor air quality, and structural issues. We seal crawl spaces with vapor barriers and insulation to create a dry, energy-efficient environment.

French Drain Installation

French drains effectively manage excess surface water by redirecting it away from your foundation. Our customized systems help prevent water damage and keep your landscaping intact.

Basement Floor Sealing

Moisture and radon gas can seep through unsealed basement floors. We apply high-quality waterproof sealants to protect your basement from dampness, improving air quality and durability.
