Featured Review

Verified review from Google

I moved into a new property that required some updated plumbing repairs. I also replaced some plumbing fixtures. Recently I needed to have my drain snaked. Every technician has been friendly and thorough explaining what needed to be done and provided their professional opinion. Always received a quick response when coordinating my appointment. I would highly recommend their services to anyone. Thank you very much Tom and everyone else at Harb plumbing. You are doing an amazing job.

ProScore profiles are built from publicly available information and official public registries, and scored using ProScore’s own methodology. We check this data against third-party sources and work to keep it accurate, but records change and errors can occur. A ProScore is informational only — it is not a guarantee, endorsement, or recommendation. Before hiring any contractor, you should independently verify and confirm all relevant credentials, licences, insurance (including WSIB coverage) and references directly with the contractor and the issuing authority.
