How New Windows Improve Energy Efficiency in Ontario Homes

Most homeowners we meet in Vaughan are shocked by how much energy (and money) they lose through old windows. Up to 25% of your home’s heat loss happens through inefficient windows.

Here’s how Polaris window replacements fix that:

Triple-pane glass traps more warm air in winter and cool air in summer
Low-E coatings reflect heat and block UV rays
Argon gas insulation between panes reduces heat transfer
Tight, foam-sealed installation means no drafts—ever

🌬️ Whether you're in a Vaughan heritage home or a suburban bungalow in Vaughan, upgrading your windows = lower hydro bills and more year-round comfort.

🏡 Window Replacement for Different Home Styles in the GTA

Not every house is the same—and neither are the windows. Polaris customizes every order to match the structure and character of your home.

Examples:

Victorian/older homes in Vaughan – Best with casement, double-hung, or bay windows
Suburban homes in Brampton, Milton, Mississauga – Popular choices: sliders, picture windows, awnings
Modern infill builds – Love the clean look of black-trim fixed or casement windows

We also offer colour-matched exterior trim and brickmould options for a seamless fit—no matter your architecture.

🧰 Full-Frame vs. Retrofit Window Replacement: What’s the Difference?

A lot of Vaughan homeowners ask us which type of replacement is best: full-frame or retrofit.

Here’s the breakdown:

Type	Best For	Benefits
Full-Frame	Old homes with wood rot, poor insulation	New frame + brickmould = total seal, fresh start
Retrofit	Homes with solid frames	Faster install, less construction, cost-effective

We’ll recommend the right method during your consultation—no upselling, just what’s best for your home and goals.

Frequently Asked Question

❓1. How long does window replacement usually take in Vaughan homes?

Answer: Most standard window replacement projects take 1 to 2 days to complete. The timeline depends on how many windows you’re replacing, whether it’s a retrofit or full-frame job, and your home’s layout. For example, a small Vaughan bungalow might be completed in one day, while a larger two-storey home in Vaughan or Mississauga may take two days. Polaris always confirms the expected timeline during your consultation, and we work efficiently without rushing quality.

❓2. Do I need to be home during the window replacement?

Answer: It’s ideal if someone is home at the start of the project to greet our crew and review access details. After that, you don’t need to stay the entire time—as long as we have safe indoor access to the areas being worked on. If you're stepping out, our team will lock up, clean up, and update you before leaving. Polaris is fully insured and trusted by homeowners across the GTA.

❓3. Can window replacement be done in the winter?

Answer: Yes—we replace windows year-round, even during Vaughan winters. Our crew uses cold-weather-rated sealants and installs one window at a time to minimize heat loss. We work quickly and cleanly, making sure your home stays warm throughout the process. In fact, winter is a great time to spot which windows are causing drafts or heat loss!

❓4. What happens to my old windows after replacement?

Answer: We remove and dispose of your old windows as part of the service—no extra charge. Wherever possible, we recycle the glass, metal, and vinyl components to reduce waste. If you’d like to keep your old windows (for DIY projects or resale), just let us know ahead of time and we’ll set them aside.

Answer: Absolutely. Polaris offers 0% interest for 90 days, plus low monthly payment plans designed to fit your budget.
