Drain & Sewer Services

No provincial trade licence required

Drain companies brand as drain companies, not plumbers: camera inspections, flushing, clog emergencies, and trenchless sewer replacement. It is equipment-heavy, emergency-priced, and one of the most franchise-contested niches in the trades.

The licensing layer, explained

Nuanced: drain cleaning, camera inspection, and flushing are generally not licensed plumbing work — but repairing or replacing drains and sewers is plumbing (306A, compulsory) and needs permits, and many municipalities require a licensed plumbing contractor to work on the sanitary lateral. Most serious drain businesses run licensed plumbers for the repair side. Municipal sewer-lateral subsidy programs (for replacing clay pipes, removing roots) feed steady work.

Insurance to expect

Sewage backups and flooded basements drive claims — carry $2M CGL with explicit water/sewer-backup response, plus equipment coverage for cameras and flush units (a camera rig alone is five figures).
