I had a broken bracket and cable on my 18 years old house. I'm a do it yourselfer but it was had to find parts. Got quoted much higher prices from others then I found Markham Garage Doors Ltd. Walked in with my broken bracket, the guy was very knowledgeable and put together the bottom bracket, roller, cable, a can of rust proofing, new nuts, bolts and expertise instructions. I was out in 10 minutes, paid for everything less than what others had quoted for the bracket alone. Got home and completed the job in 30 minutes the way they taught me. Now I'm good for at least a few more years but when the time comes for door replacement, I have no doubt that I will come back to these guys. Highly Recommended!
