We were leaving our house around 11:45 am Friday morning when suddenly the garage door wouldn't close completely. Upon inspection, I saw the chain was off the sprocket and hanging limply on the door. Not wanting to fool around with an electrical device, I figured it best to call a professional company in. There was a K&B Garage Door Company sticker attached to the garage door, so after doing a little Yelp research, I called them and explained our dilemma. The girl on the phone said that they schedule by zip code and could probably get to our job on Monday, but I said I absolutely needed to get the door fixed today since we were leaving the house later for the evening and didn't want to leave the garage door open. She put me on hold for a minute, then came back on and said a crew could be there between 12:00-3:30 pm--perfect! About 1:15 pm, Chuck and Carson came over and said the chain drive needed to be repaired, but noting the age of the unit (11 years), Chuck suggested replacing the unit, and we agreed with his assessment. He suggested a belt drive unit instead of a chain driven one which would cost about $85 more, but would have the advantages of running smoother and quieter, could operate the door through a phone app, and offered a lifetime warranty instead of only a 4-year one--excellent! So we asked how long would it take to install the new unit and they said about 90 minutes, which would allow us time to get ready and go out. It took them barely over an hour to install the unit and clean up, and after that Chuck patiently explained how the remotes and wall switch worked and answered all our questions. Chuck and Carson were friendly, very thorough and professional--thanks, guys! And thank you to the girl in the office for expediting our job (sorry, I didn't write down your name!)--most appreciated! Solid company that I will call again for future work--no wonder they have been in business over 35 years!
