Demand and price peak in summer. Booking outside it is the cheapest saving available on this job.
What this trade needs
We hold no licence to check for this category, so insurance and WSIB clearance are what a homeowner compares. That says what we hold, not what the province requires: nobody here has checked whether Ontario licenses this work. References and a written scope do the work a licence check would otherwise have done.
This work usually needs a municipal permit. Unpermitted work has to be disclosed when you sell, and an insurer can decline a claim arising from it.
Ask before you hire
Is this a retrofit into the existing frame or a full frame replacement?
Is exterior capping, interior trim and painting included?
What is the warranty on the seal, and is labour covered or parts only?
You asked for the trade Windows and doors, and the words "stump grinding". 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.
