Best drain & sewer cleaning companies in Ontario
These are the drain and sewer specialists in Ontario that earned the highest scores under our methodology, which weighs rating, review volume, recency, sentiment, and verification rather than star rating alone. Every business here treats drain and sewer work as a core service, not a side offering.
Looking for a plumber who covers more than drains, like water heaters, renovations, or general repairs? See our best plumbers overall list. The ranking here is narrower on purpose: it only covers businesses where drain and sewer cleaning is a primary line of work.
Picks are ranked by score and relevance to drain & sewer cleaning, so a lower overall score can rank higher here.
