Security Concerns
Cold Drafts

Rotting Frame
Broken Hardware
If these sound familiar, you’re not alone. We complete professional window installation across the GTA every day.
Everyday window problems add up fast. Drafts raise energy use, leaks stain sills and drywall, and foggy glass, noise, and worn frames make a home feel uncomfortable and outdated. Left unresolved, drafts strain your HVAC and raise bills, leaks cause mould and rot, and broken hardware creates safety risks or can leave a window sealed 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.

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!
