Hiring a window & door installation contractor in Burlington

Replacing windows and doors improves comfort, energy use and curb appeal, but poor installation can cause more problems than it solves. Ontario homeowners should look for installers who address flashing, air sealing and manufacturer specifications, not just the units themselves, since a well-made window installed poorly will still leak.

What to look for

Energy Star certified windows rated for Ontario's climate zone
Proper flashing and weatherproofing details, not just caulking
Manufacturer-trained or certified installation crews
Clear warranty terms covering both the product and the labour
Experience with your home's window type, such as casement, slider or full-frame replacement

Questions to ask

Are these windows Energy Star rated for our climate zone?
Will this be an insert replacement or full-frame, and why?
How do you handle flashing and air sealing around the opening?
What does the warranty cover, and for how long?
Who is doing the physical install, your crew or a subcontractor?

What it tends to cost

Window replacement costs can range widely depending on the number of openings, frame material and whether the job is a simple insert or a full-frame replacement with exterior trim work. Entry and patio doors often add a separate line item, and costs typically rise with custom sizes, heavier glass packages, or extra trim and brick-mould work outside. Older homes with settled openings can also need more carpentry than a straightforward swap. Get quotes itemized per opening so you can compare like for like.
