What Homeowners Say About Working With Us

My experience with Windowsville was fantastic. They were prompt from the start, provided a quick quote, and worked within my budget. Communication was excellent—they provided me with plenty of notice to prepare for the installation. On installation day, their team was efficient, friendly, and treated my home with care. The new windows and front door look great, and I’m extremely happy with both the service and the quality of the products.

Thank you to Windowsville's team for an outstanding job! We couldn't be happier with the windows and sliding glass door that they put for the entire house. They were responsive in communication throughout the process. The 2 gentlemen that came to install everything were very nice and professional. In strongly recommend Windowsville's team for anyone who wants quality product and outstanding customer service. Thank you!

Windowsville is absolutely amazing. From Arik in sales, Arthur in operations and Milan and Billy in installation. The whole process from transaction to installation was totally seamless. Windowsville is professional and trustworthy. They won't push you to buy. In fact, I waited three months to make my decision to replace all my windows and doors. Great quality and superb installation. Thank you very much for enhancing the look of my house and saving me a lot on my energy bill.

Windows FAQs

How do I know when my windows need to be replaced?

Common signs include drafts, condensation between the glass, damaged frames, difficulty opening or closing, and noticeable changes in indoor comfort. If you're unsure, our team can assess your existing windows and recommend whether replacement makes sense.

How much does window replacement cost?

The cost depends on the size, style and number of windows, glass options, and installation requirements. We provide a detailed quote based on your home and the options you choose, so you'll know the cost before moving forward.

How long does window replacement take?

Installation time depends on the size of your project, but many residential window replacement projects can be completed in one day. We'll confirm the expected installation schedule before work begins.

Are new windows really more energy-efficient?

Yes. Modern windows with energy-efficient glass, insulated frames and proper installation can help reduce heat loss and drafts. The result is more consistent indoor temperatures and less demand on your heating and cooling system.

Can windows be replaced in winter?

Yes. Windows can be replaced during the winter. Our installers work one opening at a time and minimize how long your home is exposed while the old window is removed and the new one is installed and sealed.

What warranty do you offer on your windows?

Our windows are backed by a transferable Lifetime Limited Warranty covering key window components, subject to the manufacturer's warranty terms. Windowsville installations are also backed by our 10-year labour and installation warranty.

Why choose Windowsville for new windows?

Windowsville combines Canadian-made windows, professional installation and years of local experience across the GTA. From choosing the right windows to installation and after-sales service, one team takes care of your project from start to finish.
