Chimney Sweep and Inspection Costs in Canada

Chimney inspections follow a three-level standard used across North America. Level 1 is a visual check of the accessible parts of a system that is maintained and unchanged, the level that accompanies a routine annual sweep. Level 2 adds a camera survey of the flue interior and inspection of accessible attics and crawlspaces, and it is the level real estate transactions and fuel changes call for. Level 3 involves opening the structure to investigate a suspected hidden hazard, and it is priced as the repair investigation it is.

Published Canadian data reflects the ladder: around $100 for a Level 1, $175 for a full visible-component inspection, $200 to $400 for cleaning with inspection, and roughly $600 for a Level 2 camera survey. If a company cannot tell you which level it is quoting, it is not quoting an inspection.

WETT, Wood Energy Technology Transfer, is the Canadian certification program for people who inspect wood-burning systems. Insurers routinely require a WETT inspection when a home with a wood stove or fireplace changes hands or changes policy, and some require one on a schedule. A standard sweep is not a WETT inspection, and a sweep ticket will not satisfy an insurer asking for one.

Published Alberta pricing puts a WETT Level 1 inspection at $225 for the first chimney, and a wood stove inspection with an insurance report around $300. If you know you need one, book it with a WETT-certified inspector directly rather than paying for a sweep first and discovering the certification is a separate service.

Creosote condition is the main variable on the sweep itself. A flue swept annually cleans quickly. A flue with years of glazed creosote needs rotary cleaning or chemical treatment, and the price moves accordingly. Frequency is genuinely the cheapest maintenance: the annual sweep stays at the annual-sweep price.

Access and height come next. A steep or very tall roof adds setup time and safety equipment. Multiple flues price per flue. And repairs found during inspection, from a cracked liner to a failing crown, are quoted separately from the sweep, which is as it should be.

The Canadian fire safety guidance is consistent: wood-burning chimneys should be inspected annually and swept when inspection shows buildup, which for a regularly used wood stove usually means annually, and for an occasionally used fireplace can stretch longer. Gas fireplaces produce no creosote but still merit periodic inspection of the venting and the unit.

The timing that matters is autumn, before heating season, which is also when every sweep in the country is booked solid. Booking in late summer is the difference between an appointment and a waiting list.

A sweep quote should state the inspection level it includes, because that is where prices genuinely differ.
