About Ontario Basement Waterproofing
Basement waterproofing for homes and small buildings across Ontario.

What we do
Ontario Basement Waterproofing helps with interior and exterior waterproofing, weeping tile, sump pumps, backwater valves, crack injection and window-well drainage.
We cover Toronto, Ottawa, Mississauga, Brampton and the rest of Ontario. Each city page explains local ground conditions, groundwater, flood history and the authorities to check with.
How we talk to you
Plain language, photos of what we find, and a written scope you approve before any work starts.
