Why there's no price list.
Every replacement window is made to measure for a specific hole in a specific wall. The same nominal “window” can be a simple vinyl slider in a bungalow or a triple-glazed aluminum unit craned to a third floor — and the two aren't within shouting distance of each other on price. That's why serious manufacturers quote from measurements, not menus.
As a rough orientation only: in the current Ontario market, most professionally installed, made-to-measure replacement windows land somewhere in the several-hundred-to-low-four-figure range per opening, with standard vinyl at the lower end and large, custom or architectural aluminum units above it. Treat any number you read online — including that one — as a starting point for conversation, never as a quote.
What you can know before anyone visits is which factors drive the number up or down. There are six that matter.
Frame material
Vinyl is the value benchmark — excellent insulation at the friendliest price. Thermally broken aluminum costs more per opening but buys slimmer frames, larger spans and architectural finishes. Most homes mix both: vinyl where practicality wins, aluminum where the design does.
Size & style
A standard casement is the baseline. Bays, bows, oversized picture windows and custom shapes take more material, more engineering and more installation time. Operating styles (casement, awning, hung, slider) also price differently than fixed glass.
Glazing package
Double-pane Low-E argon is today's standard. Triple glazing adds cost but pays back in comfort, quiet and heating bills — especially on north faces and busy streets. Laminated, tinted or privacy glass add to the package price.
Installation complexity
Full-frame replacement (removing the old frame entirely) costs more than a retrofit insert but is the right call when frames are rotten or you're losing glass area. Second-storey access, masonry openings, capping, brickmould and interior trim all move the labour line.
How many openings at once
Fixed costs — measuring, delivery, crew mobilisation — spread across the whole job. Fifteen windows in one project cost meaningfully less per opening than fifteen windows across five separate projects.
Rebates
Ontario's Home Renovation Savings Program currently pays $100 per rough opening on ENERGY STAR® certified windows and doors when bundled with a second efficiency upgrade — real money on a whole-home project.
How to compare quotes fairly.
Two quotes with the same bottom line can describe very different projects. Before comparing totals, check that each quote answers the same questions:
What exactly is being installed? Frame material and series, glazing package, Low-E and argon, hardware — specified per opening, not “premium windows” in the abstract. If you're weighing materials, our vinyl vs. aluminum comparison covers the trade-offs opening by opening.
What does the installation include? Full-frame or retrofit, capping and brickmould, interior trim, insulation of the gap, disposal of old units. The cheapest quotes usually go quiet exactly here.
Who stands behind it — and for how long? Warranty terms on glass, frame, colour and workmanship, and whether the company that quoted is the company that manufactures and installs. Our vinyl windows carry a 40-year glass warranty, and the crew that installs your windows works for us, not a subcontractor.
Is the rebate factored in? On ENERGY STAR® certified units, Ontario's current program can return $100 per opening — our rebate guide explains the conditions.
