Find the Dimensions & Size to Replace a Broken Garage Door Spring

Garage door springs are a key component to any garage door opener system, and when they fail it can leave your door inoperable. For those who keep cars in their garage, a broken door is a serious problem that needs fixed fast, so our experts wrote an easy guide to finding the right replacement garage door spring size and how to repair springs fast.

How to Determine if a Spring is Broken?

Before spending money on a replacement spring, make sure it is actually broken. There are two types of garage door springs: torsion springs and extension springs.

Torsion springs are typically mounted above the garage door and keep the door properly balanced. They keep the door securely in place, either in the raised or middle position. Some movement is to be expected, but if the door doesn't stay in place, the torsion springs are likely failing. 

Extension springs are mounted above the door or on the sides. Any gaps between coils indicate that this spring is starting to fail.

If you hear unusual noise such as squeaking during a door's operation, it can be another indication that a spring may need repaired or sprayed with lubricant. Read up on why springs break and how to prolong their lifespan here.

Can I Repair My Own Garage Door Spring?

While it may be tempting for DIY enthusiasts to try and fix their garage door spring themselves, you should always hire an experienced professional to handle spring adjustment and replacement. Garage door tension springs are designed to store great amounts of power, and when unproperly handled they can seriously injury or even kill someone. Don't wind up in the hospital after unwinding your spring and leave the installation to a professional.

How Much Does It Cost to Replace Garage Door Springs?

The cost to replace garage door springs averages between $200-210. This breaks down to $20 or $30 for the springs and up to $180 for the labor. Whether you have them repaired or replaced depends on their condition. Squeaky springs may only need lubrication as an easy fix, but if they are still noisy, replacing the springs is the best option. If the door is difficult to open or close, the springs may require re-fitting, which can be an additional cost.

Finding the Size of a Replacement Garage Door Spring

It's important to know the dimensions of the replacement garage door spring you need before going to order one. See our handy video below for a step-by-step guide to finding the length of spring (in inches), wire size, inside diameter and the wind of the spring, which is either left or right wound.

How Long Should Garage Door Springs Last?

Garage door springs will typically last between seven and nine years with average use, which is approximately four cycles per day. With more frequent use, the lifespan of the spring may be just four to six years.

Those who live in a wet climate may see a shorter lifespan for garage door springs, because moisture can cause rust to build up and increase the friction, which will wear out the springsquicker. Installing top and side weather seals on your garage door can stop rainwater, snow, and other elements from coming into contact with your spring and damaging it. Lubricating your springs every few months is another great way to reduce friction and keep them functioning for years to come!
