Maintenance

A typical garage door may weigh hundreds of pounds, and is typically sprung by a torsion or extension spring to counterbalance the weight of the door. The great force on these springs can make them dangerous to replace for the inexperienced or incautious handyman. Many cases have been reported where even experienced garage door technicians have suffered severe lacerations and/or broken bones in the replacement of garage door springs. Garage door torsion springs are rated in cycle life, with 10,000 cycles being the industry standard minimum, and upgrades available to around 100,000 cycles. The average spring breaks about every 7 to 12 years. If a garage door has two or more springs and one breaks, all springs should be replaced to maintain proper balance.
