Security Concerns
Cold Drafts
Outside Noise
Rotting Frame
Broken Hardware
If these issues sound familiar, you are not alone. We complete energy efficient window replacements across the GTA every day.
Drafts raise energy use, leaks damage sills and drywall, and broken hardware makes windows hard to operate. Foggy glass, noise, and outdated frames reduce comfort and add frustration. Left unresolved, these issues worsen. Drafts increase utility bills, leaks lead to mould and rot, and faulty hardware creates safety or ventilation concerns.

⭐⭐⭐⭐⭐
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!
