Best siding contractors in Ontario
These are Ontario's top siding specialists, ranked by our earned composite methodology, which weighs rating, review volume, recency, and sentiment together rather than star rating alone.
Roofing work is judged on its own page: see the best roofing contractors in Ontario. The businesses here are ranked because siding installation and repair is a core, recurring part of what they do, not a side offering.
Picks are ranked by score and relevance to siding contractor, so a lower overall score can rank higher here.

6. Ontario Siding and Gutters
4.3 (6 reviews)score 68/100
Estimator Ed and installer Alem draw repeat praise for punctual, skilled work on siding and gutter repairs at competitive prices. The score is built on just 6 reviews, though, so treat it as an early read rather than a settled track record.

- Punctual, skilled installer (Alem)
Watch out: One recent reviewer flagged a curt phone greeting and a lost quote request, so follow up directly if you don't hear back.
