Waterproofing Business Directory
Provincial directory of basement waterproofing contractors—verification policy, quote-comparison tips, and listings across Ontario.
How this Ontario waterproofing directory works
Waterproof Ontario lists basement waterproofing and related foundation contractors across the province so homeowners can compare options. We are a directory and editorial guide—not a contractor and not a licensing board. Use listings to shortlist, then verify licenses, insurance, and written scopes yourself before you hire.
What “verified” means
- A verified badge means our team reviewed the listing for basic accuracy (identity, contact paths, and service categories) after a claim or editorial check.
- It does not guarantee workmanship, pricing, permits, or that the contractor holds every license your project needs.
- Unverified listings may still be useful leads—treat them as starting points and confirm facts independently.
How to compare quotes safely
- Get at least three written scopes for the same water-path diagnosis.
- Compare method, exclusions, warranty (labour vs materials), and who pulls permits—not only the bottom line.
- Sanity-check prices against our Ontario cost hub.
Coverage and service taxonomy
Listings focus on basement waterproofing, exterior waterproofing, foundation repair, sump systems, and drainage across Ontario cities and regions. City landing pages (for example Toronto, Mississauga, Vaughan, Oakville) explain local context; this hub is for browsing and comparing providers province-wide.
See service areas for the city index, or get listed if you are a contractor. To correct a listing, contact us with the business name and the change needed.
