Overhead garage door repair

Sectional overhead garage doors if maintained and operated properly are one of the safest garage door systems that are available today on the markets. Most common problems of overhead garage doors that require a professional attendance are: (#2) Torsion spring replacement, Cable replacement, and Off-track overhead garage door.

How overhead garage door operates?

 When closed the door is basically hangs on two steel suspension cables (#8) connected to the bottom section on one end and to a (#3) pulley on the other end on both sides of the door. The pulleys are connected to a (#4) torsion bar and torsion springs are mounted on it as well. The springs on one side are connected together to a bracket and the bracket is mounted to the wall. On the other side springs are locked on to the torsion bar. When the door is closed springs are under highest tension in the opening and closing cycle, when you open the door springs are doing most of the lifting.

Why off-track occurs?

If one of the suspension cables snaps or comes out of its pulley the overhead garage door becomes unbalanced. One side that is still attached to the system pulls the door up and the other side with the broken cable has no support and due to gravity and the door weight pulls that side down.  Please keep in mind that the overhead garage door torsion springs are still under a very high tension, forcing the door to open or to close can lead to a greater damage to the system or some serious injuries! 

Your garage door can eventually get off-track due to one or more of the following reasons: 

  • Broken springs
  • Unbalanced door
  • Damaged rollers


Off track door

  • Loose parts
  • Old and worn cables
  • Cracked sections


off track door

Fact: An off-track door can lead to mishaps. We recommend keeping a safe distance and calling a professional right away. Our 24/7 emergency service team is ready at any time to answer your call.

Tip:To insure a longer lifespan and a smoother operation of your garage door, all moving parts of the door should be lubricated semi-annually . Use a silicone based lubricant spray for the tracks. Do not grease the tracks since grease will only create a sticky surface and attract more dirt and dust, eventually resulting in more friction. Use machine oil to lubricate the bearings, hinges, and the rollers.
