Very responsive and attentive service. They installed a new garage door 5 years ago. No issues with it until my garage door stopped working abruptly after Christmas. I contacted them and they arranged a prompt service call. I sent a short video of the garage door's lack of response. When the service person arrived, he had reviewed the video and had a good diagnosis of the problem. He fixed it within an hour. He explained the issues to my level of satisfaction and understanding. He oiled and inspected the door mechanisms. The price was fair and reasonable. LI was extremely satisfied with the service. I would definitely highly recommend Markham Garage Doors for all garage door issues!

A garage roof leak ruined my garage door opener. Markham Garage offered me several solutions to repair or replace it. They replaced the unit and everything works great. Most importantly, they were responsive to the calls and emails. They scheduled it quickly. The technician showed up on time, he was friendly, worked fast and the work was clean. He then explained how the job went, how the new unit works and answered my questions.
Great work. Thanks.

“We had new beautiful doors installed but it wasn't until the capping was installed that made the job complete. Robert who completed the job was a true craftsman in completing the installation of our capping. The way he installed the capping was the best I have ever seen. No messy caulking was used as the aluminum is installed behind the brick and stone given it the most cleanest and professional look that any homeowner can be proud of. If you are getting new garage doors installed make sure you get the capping completed by Robert, which will provide a complete and great look to your home. He does it right”
