Broken Hardware
If these sound familiar, you’re not alone. We replace efficient windows across the GTA every day.
Everyday window problems add up. Drafts raise energy use, leaks stain sills and drywall, and worn hardware makes windows difficult to open or lock. Noise, foggy glass, and a tired look quickly reduce comfort. Left unchecked, drafts strain your HVAC, leaks damage floors and drywall, and weak 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.
