Our 30,000sqft factory in Woodbridge uses modern robotic technology for increased precision. Since there is no middle man, you will receive factory-direct pricing, quality products and installations done right, Windtek Windows & Doors are the experts you can rely on. We have locations across Ontario, including Woodbridge, Kitchener / Waterloo, and the Georgian Bay Area.

FREQUENTLY ASKED QUESTIONS

- Doors: Entrance, Patio, Storm, garage doors
- Windows: Replacements, Bay, Bow, End-Vent, single hung, single slider, double hung, double slider, awning window and casement windows
- We do NOT offer interior doors
Depending on your home and existing windows or doors, there are two common forms of installation:
Â
-

-
Brick-To-Brick: We take the whole frame out and re-do the frame and section of the wall

We make all our windows and door products ourselves. As such we engineer them with features like slider tilts for our windows that make them easier to clean then traditional windows or doors.
Contractors often get preferential pricing from window manufacturers. Yet while they may get a cheaper price than you will, the high fees for labor far outstrip any money you'll save by having a contractor order your replacement windows. The job becomes much cheaper when you don't have to pay for a window installer.
Installing new home windows are definitely worth the investment depending on what you are looking to get from them. Replacement windows bring value by increasing your home's resale value, increasing energy efficiency and increase your home's overall aesthetics.
Not always, but it depends on the door you choose. The average front door cost is $2,500 (single door, excluding sidelight), with a range from $1,500, for the most basic and budget-friendly options, to over $5,000, for more upscale exterior doors.
