Repairs and Maintenance

Annual garage door tune-up service help prevent emergencies. Our processional safety check includes track lubrication and track adjustments. Just as with other complex machinery, your garage door requires routine maintenance to ensure proper and safe operation. Doors need to work in a synchronized manner to raise and lower the door properly. Over time and different weather conditions doors do get out of adjustment. Such situations can cause premature breakage and an emergency repair need.

Our professional garage door technicians inspect your garage’s door panels, springs, sensors, safety release, hardware, track, and other necessary parts. Our trained and experienced technicians perform this inspection to ensure they’ve done their repair work correctly, and to identify any potentially troublesome garage mechanisms that could become serious problems. If a problem is identified, you will be advised of corrective options.

Customer Reviews

★★★★★ Mark Smith - Potomac, MD
Jon was very responsive. Came over quickly to take a look at the work done. Provided a number of options and then was able to schedule the work to be done the next day. His team worked quickly and did a great job on the two new garage doors that I had installed. I would highly recommend his company and use them again in the future.

★★★★★ Christine Gschwend - Potomac, MD
Diamond Garage responded immediately to an email I sent. We set up a date and I asked them to call 30 minutes prior to their arrival, which they did. They explained the work that needed to be done and gave me prices. The garage door opener was replaced as well as the springs and track wheels. They were very courteous and efficient. I thought the price was fair.

★★★★★ Zahir Albadawi - Potomac, MD
John is a very concerned, knowledgeable, and expert guy. When I asked his opinion about different models of openers he provided me a variety of useful information about each model with its cons and pros. Jon did a neat job in installation and wiring of my new garage door opener. Very happy with his service, quality of the job and the most important one, his honesty. I highly recommend him. John changed our garage door opener, changed the rollers and tuned the door.
