The transformation
Imagine a home that's warm, quiet, and easy to live in — with custom-fit windows that stop the drafts, cut the noise, and finally look the part. That's the difference our customers describe: "we can live comfortably now, draft and leak free."
The guarantee
A lifetime non-prorated, fully transferable warranty that never shrinks — and passes to the next owner. We've been here since 1979, and we'll be here to honour it.
Happy homeowners
We had a great experience working with the Windtek team and the owner Danny. They are professional and true window experts. We will be referring them to all our friends and family!
Our new windows and doors are just what we needed — and at a very competitive price. The installers did a wonderful job. This company's people are great start to finish.
Ryan came through last minute in a pinch to help me with some new windows. He came through with great timing and helped me with the installation before I listed my property. BIG thank you!
Best price, good quality, fast delivery, no unpleasant surprises.
Danny was a window professional of the highest order! I like that they educate you and don't try to sell you something specific. Danny made me feel my input was the most important.
