Best window companies in Toronto compared

*Ratings reflect publicly available HomeStars figures as of September 2026. Review platforms update continuously, so figures may change over time.

A note on NorthStar: you may also see NorthStar windows mentioned in Toronto renovation research. NorthStar is a window manufacturer rather than a local installation company, so it isn't compared here alongside the companies above. If an installer offers NorthStar product, ask which company is doing the actual installation and check that company's own reviews separately, since installation quality varies by installer even when the window brand is the same.

Frequently asked questions

What is the average cost of replacing windows in Toronto?

Window replacement costs in Toronto usually depend on window size, style, frame material, glass package, and installation complexity. Many homeowners see projects ranging from several hundred dollars per window to several thousand dollars for larger or custom designs.

Which window companies manufacture their own products?

Some companies manufacture their own windows, while others mainly sell products made by third-party brands. Companies that manufacture their own products often have more control over quality, design options, and warranty processes.

Are vinyl windows a good option for Toronto weather?

Vinyl windows are one of the most common choices in Toronto because they handle changing temperatures well, require little maintenance, and offer good energy efficiency. The quality of the frame and glass package often matters as much as the material itself.

How many quotes should homeowners get before replacing windows?

Most homeowners compare at least three quotes before making a decision. Looking at multiple options helps compare pricing, warranties, products, installation quality, and the overall value offered by different companies.

What should homeowners look for in a window warranty?

A good warranty should clearly explain what is covered, how long the coverage lasts, and whether it can transfer to a future homeowner. It's also useful to understand whether labour, hardware, glass, and installation are included.

What should I look for when comparing window companies in Toronto?

Compare HomeStars and Google ratings, ask what the warranty actually covers (parts, labour, and glass), confirm who does the installation (in-house crew or subcontractor), and get at least three quotes so you can compare pricing and product options side by side.

Is a bigger national retailer or a local specialist better for window replacement?

Both can do good work. A national retailer offers broad product selection and convenient locations, while a specialized local installer typically focuses on windows and doors specifically, which can mean more consistent installation crews and a company more invested in its local reputation. Compare reviews and warranty terms for the specific company, not just the category, before deciding.
