Window Installation in the GTA
Window Installation, Done Right the First Time
Window installation covers new openings — additions, converted spaces, and homes where a window is being added where none existed. It's a different job than replacement, since it involves cutting a new opening into existing wall structure and framing it correctly before a window ever gets set.
We frame the rough opening to the window manufacturer's exact specifications, then flash and seal it the same way we would a replacement, since a new opening has zero margin for error on water management — there's no old window's track record to fall back on.
What's Included
- New opening framing to manufacturer spec
- Proper header sizing for structural openings
- Full flashing and weatherproofing
- Interior and exterior trim finishing

"Amazing work and an outstanding crew. Very professional, energetic, and a pleasure to work with from start to finish. They communicate openly throughout the entire project, show up reliably, and get the job done right. Wouldn't refer anyone else."
