The springs on the garage door wasn't functionally properly and so I contacted Superior Door Service, Inc. They were pretty booked up however, he got me in during the mid day - David was on the spot! The replacement springs are working great. I appreciate how he explained to me what happen and how to maintain the garage door. He actually sprayed the wheels down with some lubrication. I appreciate how he didn't change up the prices - I paid exactly what he quoted me. I am impressed with their expertise and craftsmanship. I would recommend them.
