I have a guy whose business is called "Garage Door Man". I have called him twice. Once to finish an install of an opener I could not get aligned properly. He came the next day, a Sunday, and finished the job for $75. Second call was to replace a spring the "exploded." He came the same day at 8:00 pm. Replace both springs, added safety cables for $95.
I have a heating/cooling company that responds right away too. Guess I lucked out in NW New Jersey.
