The quote, the delivery and service were all top notch. John and Kate were not only super helpful but provided good recommendations on what to do with my garage door. The price point was very reasonable as well compared to market. Will definitely recommend them.

Incredible customer service and excellent repair work. ONC arrived on time (same day service), and very quickly diagnosed the trouble with my garage door. John took the time to explain to me the issues and how he was going to repair them. He didn’t rush, yet completed the work faster than I expected. He made some recommendations for other repairs and I asked if he could stay a bit longer and do those as well, which he was happy to do. I would highly recommend ONC Garage Door Services to anyone needing quality garage door installations or repairs.

Amazing service and work – contacted them through their website and promptly heard back from John. Came out the next day to diagnose and fix. I had a bend in the top of my garage door I was told was not repairable by one company, and quoted almost triple by another company to repair with wood temporarily. John’s quote came in at a fraction of what I was previously quoted, using metal / better materials that would be a proper fix that was not temp. He arrived within the scheduled time, was able to explain what the issue was, how it was effecting the function of the door motor, and how he could fix it. Within 20-30 mins he had the work completed, and garage door back to operating as before. HIGHLY recommend, could not have asked for better service. John is very professional and knowledgeable. Thank you John!

ONC Garage Door Services installed our new garage door nearly 4 years ago, and when I called to request a service visit, they had my records immediately in hand and booked a ‘tune up’ for the next week. The service person was on-time, knowledgable and friendly and took care of everything in less than half an hour. I could not be happier with ONC product or service.

John is very professional. He not only did a great job of changing the spring of my garage door, but also gave me best advice on maintenance. Highly recommended!

Very quick response following the call for repairing the garage door spring break. The technician came the same day in the evening and repaired the broken spring. Moreover, he pointed out other issues that could cause door failure and agreed to fix them on the spot. Overall great customer service and quality of work.

Second time using ONC. Second time thoroughly impressed. Katie was extremely pleasant and patient trying to look up an older invoice that I had misplaced. Also managed to get me in the same day despite it being later in the day. Had John come in and quickly sort out the problem despite a few obstacles my garage ceiling presented. Much like the first time, he was extremely thorough and made sure everything else was running properly. That includes his previous work that was unrelated. Start to finish they go over and above.
