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

★★★★★ Carol Ensor - Rockville, MD
Jon actually called me to schedule the appointment which was great as I tend to be a procrastinator. He showed up on time and was very friendly and professional. He explained everything he was going to do and made a recommendation for me to replace the pulleys as they were the originals and were preventing the cables from running smoothly causing the doors to jerk as they went up and down. I am so glad I paid for this extra service as the doors run GREAT now!! (by the way, he only charged me for the pulleys and not the labor as he had to take the cables down anyway to do the tune up). The garage doors open and close so smoothly and quietly now. It is like having new garage doors. I was very impressed with the service and Jon and would definitely use him again. I would recommend him to anyone. So glad I got this work done.

★★★★★ Randi Caplan - Rockville, MD
It went great. Jon showed up on time and was very personable. He did a great job and I will definitely use him again. I strongly recommend his services to anyone needing help with garage door openers. He took the time to show me how to change the light bulbs and remote control batteries. He replaced rollers, lubricated hinges, checked garage door opener for wear.

★★★★★ T. L. Angie's List Reviewer - Rockville, MD
They went over the details about the look of the new garage door before ordering and what options we had. The work was done professionally and in the time frame that was specified. They were very honest, professional, and client friendly. Their price was approximately $200 cheaper than other estimates.
