DIY Spring Repair is a Risky Job

There are many reasons why garage door springs or cables may snap/break, including:

  1. Aging/repeated use
  2. Lack of maintenance
  3. Objects striking the door
  4. Items jammed in the tracks
  5. Aggressive lifting/closing actions

If a garage door spring or cable has broken, the door is essentially out-of-service until the repair/replacement can be completed. Due to the inconvenience this situation can create, it stands to reason that it should be taken care of as soon as possible.

At this point, homeowners think they can take the do-it-yourself approach here, as they would for many other projects around the home. However, the DIY approach is not recommended and in fact highly discouraged due to potential safety risks/vulnerabilities for homeowners, their families and their property. Here’s why.

“My neighbor did it, I should be able to do it, too.”

The counterweight system, which is secured by the springs, is connected to the hinge at the bottom of the door, to the lifting cable and to the steel shaft housing the spring. The entire system is under extreme tension, equivalent to the total weight of the door. Trying to lift the bottom hinge that is solidly bolted to the door is like lifting anywhere from 125lb (single door) to 225lb (double door). If you also have a row of windows on your door, add about 5 to 15lb per window. One false move and you could end up injuring your face or hand.

“Only one of the two springs broke!”

Even if you think it’s only 50% of the weight of the door that’s being held, you should know that it’s still too much. The most important thing is your safety – especially avoiding any serious injury. In the end, you also have to properly balance the two springs in order to prevent your door from rebounding.

“My garage door opener will hold the door.”

The drive mechanism that pulls the door to lift or lower it wasn’t designed to hold that much weight. A garage door opener is simply a substitute for human action, as if you were to lift your door with one hand. A well-balanced door weighs between 8 and 10lb and the acceptable variance for proper balance is around 5% of the total weight of the door.

Do business only with licensed professionals.

Garage door spring repair requires experience and expertise. It is important to correctly calculate the total weight of your garage door, including any attached parts while also accounting for weight of the windows, if any.
