Above & Beyond Door Systems were the ones who originally installed my garage door ten years ago. That's a long time for there to be no problems, whatsoever. When a spring broke on night recently, it wasn't too surprising, given the age.

I called Above & Beyond at 8PM, and they were here the next morning, promptly at 9. He replaced the spring, and had the thing fixed in less than 20 minutes. It worked beautifully. I couldn't believe how quickly they addressed the issue--we were barely out of commission. It was also a good value. I highly recommend them.
