A garage door cable is always under a lot of pressure, with extreme tension. You should not attempt to service, repair, or replace a garage door cable on your own. This job is best left to a professional who can safely work with the garage cable. Garage cables make it easy for doors of all weights to be lifted, by balancing the weight of the door against spring tension. This all goes very smoothly when other parts such as the garage door drums are also intact and strong.
It is important to understand some facts about your garage door cables. We always help our customers learn more about garage door maintenance service and general tips for taking care of their home garage. If you have a popular standard-lift garage door, your cable is most likely around a foot and a half longer than the height of your garage door. Of course, Garage Door Houston can take the proper measurements for any garage door cable replacement. For standard-lift residential garage doors, the cable length should be the door height plus 18 inches. When measuring an old cable, measure the full length including loops, spools, thimbles, and stops.
