If I could give six stars to Andrew, I would. I found his ad on Kijiji and he came for an estimation. He was prompt and professional. The door exceeded my expectations. It was installed in just one day. Instead of 6 weeks, it took short three weeks to make our custom order. Very happy with the result. Highly recommend!
