More than basements
We're expanding. Water protection for your whole home, from roof to foundation.
A leak can begin at the roof, work its way through an exterior wall, spill from an eavestrough, or build up around the foundation. Waterproof Ontario helps you find local contractors for the water problem you have, wherever it starts.
Free homeowner consultation. Local Ontario contractor connections.

A water problem is not always a basement problem.
Water follows gravity, gaps, and the easiest route through a building. So the first sign of trouble is not always the source. A ceiling stain can be a roof issue. Water near a wall can be linked to siding, flashing, or drainage. A damp basement can start with runoff collecting outside the foundation.
Waterproof Ontario now helps homeowners take a broader view. Our platform connects you with local contractors for water-intrusion concerns across the home, from the roofline to the soil below your foundation. Start with the symptom you see. We'll help point you toward the right type of professional.
Start with the water you can see.
1. Tell us what is happening.
Select the area of your home where water is appearing or describe the issue in your own words.
2. See the relevant service path.
We help you understand whether the problem may call for roof, exterior, drainage, foundation, basement, or restoration support.
3. Connect with local help.
Request a free consultation and take the next step with a contractor serving your area.

Ontario — September 9, 2026
Waterproof Ontario has expanded its homeowner resource and contractor-matching coverage beyond basement waterproofing. Ontario homeowners can now use the platform to find support for water-intrusion concerns across the home — including roof leaks, siding and exterior water entry, eavestroughs and drainage, sump pumps, concrete crack repair, moisture control, and water damage restoration.
Water doesn't follow a neat path. A damp basement can stem from drainage outside. A ceiling stain may point to a roof or flashing problem. Homeowners need a place to start that considers the full route water can take through a home.
