When the seal fails and moisture creeps between the panes, you don't need brand-new windows. We swap the sealed glass unit only — saving you up to 60%, with most installs done in about 30 minutes.

Modern windows are sealed glass units — two panes with insulating gas in between. When that seal eventually fails, moisture sneaks in and you get permanent fog, condensation, and streaks you can't wipe away from either side.
Window companies love to quote you a whole new window. You don't need one. We manufacture a new sealed unit to the exact size and swap only the glass — your frames, trim, and walls stay untouched.
Our mission is to provide homeowners and businesses across the GTA with an innovative, cost-effective, and eco-friendly solution for foggy and damaged windows. We specialize in glass-only replacement, a unique approach that preserves your existing window frames while giving you the crystal-clear view you deserve. We're committed to delivering high-quality craftsmanship, excellent customer service, and the peace of mind that comes with making a sustainable choice.
We offer a suite of specialized glass replacement services tailored to meet your unique needs. Our Standard Treatments are designed for those looking to fix broken or foggy glass without the expense and hassle of replacing the entire window frame. For homes with custom or larger windows, our Custom Treatments provide precise and cost-effective solutions with tailored quotes to match your specific requirements. For business owners, our Commercial Treatments offer on-site installations to meet the demands of various commercial projects.
Just one foggy pane or a whole property — standard, custom and commercial glass, all made to measure.
