This is the second time that we used Elmer in the last five years. The first time was to replace our garage door springs. He didn't believe that our door was 320 pounds, so he came here that evening to weight it. He then sourced high cycle springs for us at my request and installed them soon as they arrived. I was lazy so never provided a review then, but I was really pleased.
Fast forward to February this year, when our garage door opener gave up. I researched and found the Chamberlain's Ultimate MyQ Belt Drive to be the best for us and picked one up from home depot. Elmer was able to come out, remove our old one, and install the new one in a couple of hours. Three months later, no issues, it's super quiet and safer with the additional led sensors mounted on either side of the door. I wish I could find an "Elmer" equivalent in other trades.
