Last night, one of the springs on my garage door mechanism broke. It was really loud and I didn't know what happened at first. Tried to open the garage....nope. It was broken. I called Chad with Kingdom Doors. He arrived promptly at 8:30 this morning and replaced 2 springs for me. Only one had snapped but I decided to go ahead and replace both as the other may fail soon too. (See the pic...my left spring snapped) He also replaced the track rollers for a very minimal extra and adjusted part of the pulley mechanism. My garage opens and closes *so* much more quietly now. He was very professional, prompt, and extremely reasonably priced. I would highly recommend him should you find yourself with a garage door issue. Chad, Kingdom Doors, 615.810.6415.
