We DO NOT recommend any customer trying to replace garage door springs on their own. The garage door spring has a lot of tension put on the spring to assist in lifting the garage door. The garage door spring is wound with tension when the garage door technician installs the spring. A garage door spring can come unwound during an attempt to replace it and cause bodily harm. Bodily harm will occur when improper tools are used to attempt to replace a garage door spring. The cost of having a professional garage door technician replace the springs far outweigh the cost of the emergency room visit! Just give us a quick call, we can schedule an appointment!
