We Hear You
If these sound familiar, you’re not alone - we replace energy-efficient 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.
Old or poorly installed windows waste energy and money. With energy-saving replacements, backed by the government window rebate program, you’ll get a properly sealed system that improves comfort and lowers utility bills right away.

Real Results From Real Window Replacements
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.
