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.

What our customers have to say about our work
JAMES MCCAN Kitchener, ON |
Just had some windows replaced. I was very impressed with both the sales and installation services. We dealt with Ryan (sales) who was very professional and very informative. He even went as far as showing up the day of the installation to ensure we were happy with the work being done. The installers were great as well. They had all the flooring covered through the house where they were walking, and left with no mess to clean up. Will definitely contact Ryan in the future for future window / door replacements. |
