Getting to Know Garage Door Springs


A broken spring.

As one of the most common causes of all garage door repairs, garage door springs sometimes get a bad rap. They can seem expensive to replace, especially if your garage door uses two springs, and the temptation is high only to replace the one that seems worn or broken. But to understand why you must replace both springs, an understanding of how they work is in order.

Garage door springs have a familiar and simple design, one that’s used in everything from cars to watches to mattresses, but garage door springs have the intense responsibility of supporting up to 400 pounds of pressure every day for many years. The springs are the backbone of the garage door opener and do most of the opening, which is why a garage door will be stuck closed when a spring breaks.

The lifespan of a typical spring is 10,000 to 15,000 cycles, which translates to about 7-10 years of regular use, and this lifespan can change depending on how frequently you use your garage door opener as well as how heavy your garage door is and if you have the right garage door opener for the job (all of which can be assessed by a professional technician).

The wrong size spring or using only one when you should have two can cost you in the long run by prematurely wearing out your garage door opener and potentially even letting your garage door plummet.

Most garage doors come with all the hardware necessary for installation, and that includes garage door springs. Most modern garage doors require two springs, one on each side of the garage door, which works together to help open and close the door. Many features, such as insulation, windows and outside decoration and paneling, can add weight to a garage door, even tipping it over the 400-pound mark, making it crucial that the right hardware and springs are used.

A professional garage door technician can make sure your set up is correct and will help maintain its excellent condition, which will save you in repairs and services later.

A new spring.

Because most garage door repair companies charge per spring when making a replacement, especially when one spring seems to be just fine, it’s no surprise that homeowners want only to replace one.

However, this can cause some problems. Because garage door springs work together, they also wear together. This means that neither can be saved, even if only one break.

When you do try to install a new garage door spring with a worn garage door spring (even if the worn spring is only a few years old) the new one will have to work extra hard to make up for the wear and tear on the old one. But because the springs are on opposite ends of the garage door the new spring can work so hard it pulls the door off the track. It can also cause the new spring to break much sooner than it would if both were replaced, and chances are the old spring will break within weeks or months, anyway.

It can also be incredibly dangerous to try replacing your garage door springs, which only seems like a good idea because it looks simple from afar and you could save on labor costs, but the thousands of fingers lost, and emergency room visits that result from this attempt say otherwise. In fact, it’s sometimes impossible to find a company that will sell garage door springs to an unlicensed individual because the danger is so high. Even if you’re able to buy or rent the tensioning tool, getting the right amount of tension takes experience; you could seriously hinder the safety and function of your garage door trying to replace a spring.
