What window styles do you install?

Sliding windows in single, double butterfly and end-vent configurations, casement windows hinged left or right, single and dual-sash hung windows, crank-out awning windows, bay and bow windows, and custom curved and shaped windows.

Do you install doors as well?

Yes. STAGE insulated entry doors in smooth or woodgrain fibreglass and steel, with sidelites and transoms, plus sliding and garden patio doors.

Are the windows Energy Star rated?

Yes. Every window we install meets the current Energy Star requirements for southern Ontario, with Low-E coatings and double or triple glazing.

How long does a window replacement take?

Once the units arrive, most homes are completed in a single day. Larger projects or bay and bow windows can take two.

What does Window Wise certified mean?

Window Wise is an independent Canadian program that certifies both the window products and the installer's training and workmanship, so the unit performs the way the label says it will.

Will new windows reduce outside noise?

Yes. Multi-pane glass with Low-E coatings and tight-sealing frames cut street and neighbour noise noticeably compared with older single-pane or aluminum units.

Window Replacements

We install STAGE vinyl windows: Energy Star rated, Low-E glass, double or triple glazing and thicker PVC frame walls that stay square and seal tight for decades. Old units are removed, openings insulated and sealed, and trim finished inside and out, usually in a single day.
