We Hear You
Water Leaks

Security Concerns
Cold Drafts
Outside Noise
Rotting Frame
Broken Hardware
If these sound familiar, you’re not alone. We replace all types of windows in GTA every day.
Everyday window problems across all window types add up fast. Drafts raise energy use, leaks stain sills and drywall, and broken hardware makes windows hard to use. Noise, foggy glass, and a worn look reduce comfort and increase frustration. Left unresolved, drafts strain your HVAC, leaks damage surfaces, and broken hardware creates safety risks or can trap a window shut.

⭐⭐⭐⭐⭐
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.
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.

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!
