My garage door opener unit failed on a Wednesday. I phoned the builder to inform him of the issue. Thursday a representative of Bobs Door Service showed up and reviewed the issue. Friday morning I had a new replacement unit installed. This Warranty issue was dealt with very professionally with polite and experienced staff. I have No issues whatsoever with the way the situation was handled. I can say they stand behind their work and products. It was a freak motor failure in the unit. Thx!!
