Sweep and inspection at the low end, relining at the high end. Excludes masonry rebuild of the stack.
Demand and price peak in fall. Booking outside it is the cheapest saving available on this job.
Required by insurers. No statute requires it. Insurers require it before they will cover the work, so a job done without one can leave you uninsured.
WETT certificate numbers are not in a register you can search. Ask for the inspector's WETT number and the date on the certificate, then telephone WETT Inc. to confirm the number is theirs and still in good standing. Your insurer will also confirm which certificate they will accept, and theirs is the requirement that matters.
You asked for the trade Chimney, and the words "single room". Of the 12 businesses listed, none match every one of those.
The cost band and the licence requirements above still apply. They are what you need to judge a quote from anywhere else: whether the price is in the range, and whether the person quoting is allowed to do the work at all.
Listings here are seed data for demonstration and are labelled as such on each profile. Cost bands are what GTA homeowners are typically quoted, not offers. Always confirm a licence number against the issuing registry yourself before work starts.
