I called this company at 1000 am when I realized my garage door will never open again with my old opener. Johnny arrived at 1:15 and diagnosed my old opener and garage parts. Johnny showed me the parts needing replacing and explained the types of openers available. I chose a Liftmaster 3850. Johnny began working immediately and had all of the replacement parts available in his work van. Johnny was finished replacing the garage parts(springs, bearings and rollers) and installing the new belt driven opener. Jack showed us how the safety features worked. Johnny work was completed by 3:30. Excellent Work!
