I purchased online a new LiftMaster garage door opener to replace very old unit at my garage door. I have used Friendly Garage Doors before, they have changed broken springs earlier this year. Once more I wasn’t disappointed and was very pleases with their service. Because I purchased the opener on Amazon they would not provide a warranty, but that wasn’t necessary for the fact that the unit comes with a lifetime warranty for motor and belt. The techs came out the same day and swapped out the opener in less than an hour. I would highly recommend Friendly Garage Doors.
