We used Aztech for a property that we own in Concord, ON, they were such a pleasure to do business with. Loved the service. Everyone was so nice and helpful. I would definitely recommend to anyone that needs new windows and/or doors.

Great service! The only small issue was my bed wasn't reassembled properly at my new place but beyond that wonderful experience! Would definitely use them again.

We love our new Northtech patio doors and windows. The quality is outstanding. The installation team was fantastic! They were very skilled, attentive to detail and pleasant men. They worked hard to meet deadlines and left our home clean. We definitely recommend them to others. Their customer service was impeccable!
