Full-frame replacement

An aluminum-capped finish and a 10-year workmanship warranty
RETROFIT OR FULL-FRAME?
Not every Oakville window needs to come out frame and all. We'll tell you which ones do.
Retrofit windows go inside your existing window frame, cost less and leave your trim alone. Full-frame installs deal with rot and let you change the size or style. We look at every opening and quote what fits.

FAQs
Window questions Oakville homeowners ask
Other questions? We'll answer them when we come out.
Retrofit or full-frame: which do I need?
If your existing frames are sound, a retrofit window is installed inside the existing window frame, leaving your trim in place, which is faster and less expensive. If the frame is rotted, leaking or you want to change the size or style, full-frame is the right call. We'll check each opening at the estimate and tell you honestly.
What do replacement windows cost?
Every window is custom-made for your opening, so the price depends on size, style, glass options and whether it's a retrofit or full-frame install. The estimate is free and priced per window so you can do a few at a time.
Are the windows energy efficient?
Yes. We install KV windows, custom-made in Canada and ENERGY STAR® qualified, with Low-E glass and argon fill as standard and a lifetime transferable manufacturer warranty. Most customers notice a difference in creature comfort, heating and cooling costs in the first year.
How long does it take?
Windows are custom-built after the estimate, and install time depends on how many windows there are and whether they're retrofit or full-frame. A more accurate time frame will be established once your windows are ordered, and we cap, caulk and clean up before we leave.
Do I have to replace every window at once?
No. Many customers do the worst ones first and the rest over a couple of years. We'll quote each window separately so you can decide, and discounts are available when you order multiple windows at a time.
