Super happy with my recent service. Not only did they fix my broken spring in a quick and professional manner, but they also provided some overdue maintenance on my garage door. Now it operates more quietly than before and they even fixed some alignment issues. Their pricing was also very competitive. Highly recommend these guys.

I love working with ONC. Every thing was done perfect on time. My door was in stock and was installed right away at a resalable cost. Excellent workmanship and very professional.

Was impressed with the appointment booking process – they couldn’t fit me in due to my highly limited availability (headed out of town), but then called me back after 15 minutes to say a tech had become available. The service technician arrived on-time and was super friendly. Seemed knowledgeable. Billed a reasonable amount considering a fair amount of work needed done. Quite happy with the service I received 🙂

What a great team ONC is. We ordered two new garage doors and openers from ONC. We received a prompt response, detailed proposal (competitive) and great service and delivery. I wished ever company I dealt with delivered this level of service. Thanks ONC

Our garage door decided to cause problems on a cold (feels like -26 C) Friday night. O.N.C had replaced our garage door opener 3.5 yrs ago, so we had their number handy. We called and asked if they can drop by immediately to fix it. They dropped by in less than an hour, diagnosed the issue, explained the work to be done and cost. Once we agreed, they started to fix it. Repair work took ~45 mins and once done they explained what was done, we also go to test all our remotes to ensure no reprogramming was required. We believe the cost of emergency service call is well worth it. I would highly recommend O.N.C for garage door repair.

John offered such good service. He spent time on the phone hearing and discussing our garage door needs and answering our questions. He was efficient and professional, and from our first call to job completion was 4 days (and that’s because there was a weekend in between). Thanks for the beautiful and strong door.

The 2 garage doors at my house were noisy, misaligned and let in lots of air. John adjusted them and installed new weather stripping. Now they open/close quietly and effortlessly. To top it off, my garage will stay warmer throughout the winter and keep my daughters room above the garage warmer. I had him adjust the doors at my parents house and replace some of the wheels, did an amazing job there too.
