Mike installed a wireless garage door controller on our six year old opener, he took his time to find the right product for our door and made sure to install it properly and that it works perfectly. While he was here he also managed to tighten all the screws and lubricate all hinges and brackets, now the door works so quietly and smooth. Mike was very professional, he gave us a clear quote upfront and was very friendly the entire process, we highly recommend him!
