Hear From Our Happy Homeowners

Erik was very helpful and took the time and effort to guide me through the colour selection and installation. The final product seems well built and looks very nice. Keep in mind, these are 100% vinyl window frames.

Fadi Diab.

Amazing service and quality. I would highly recommend them. We had our front door replaced and 2 windows. One of the windows was where a wall was. They cut the hole, framed it and put a window in. We could not be happier.

Tyler Proulx.

Not only was the door exactly the one i had envisioned, the installation was done professionally and in a reasonable time. the finishing was excellent. now my family and neighbors are envious of the new "face" to our home. i would recommend capital windows to anyone, anytime..
