We Hear You
If these sound familiar, you’re not alone - we replace windows across the GTA every day.
Water Leaks
Mold Buildup
Foggy
Glass
Security Concerns
Cold Drafts
Outside Noise
Rotting Frame
Broken Hardware
Everyday window problems tend to pile up: an air draft makes rooms uneven and drives up energy use, water leak stains sills and drywall, and broken hardware leaves windows hard to open, close, or lock. Add in outside noise, foggy glass, and a tired look, and comfort drops while frustration rises.
Left unchecked, these issues usually get worse; drafts strain your HVAC and raise monthly bills; leaks invite mould/mildew, swell floors, soften drywall, and rot frames; broken hardware increases safety and security risks and can even trap a window shut when ventilation or emergency egress is needed.
When we replace your windows, we do more than swap glass. We install a properly sized, sealed, insulated system with flashing and foam to create an airtight barrier. You get steadier room temperatures, less outside noise, and lower utility bills from day one. It also helps protect walls, frames, and finishes so your home stays comfortable and looks great for years.

What Homeowners Think of Our Window Options
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.
