Broken Garage Door Spring? – You’re Not Alone

So your garage door spring is broken and you need to get to get to work or get the kids to school. Of all the luck, you think, this had to happen to you today. You may feel like your the first person this has happened to, but garage door springs are one of the most called on repairs in the garage door industry.

Garage door springs support the entire weight of the garage door. The springs are wound or stretched under pressure, tightening and loosening as you close and open the garage door. It’s the garage door springs, not the garage door opener, that supports and lifts the 300 plus pounds of weight of the garage door.

Like anything else under pressure, eventually your springs will break.  Don’t worry, you aren’t the first person this has happened too. We get calls about broken springs all the time, and especially now that it’s getting colder out

So what do you now? Read on!

Repairing Your Garage Door Springs – The 4 Step Processes

Step 1 – Get your car out of the garage

First, you probably need to get your car out of the garage. Pull the red emergency release cord located above the door to enable you to manually lift the door. Be careful, the garage door will be heavier since the spring is what renders the door weight neutral. If it’s too difficult to open yourself  have a neighbor or a family member help you. If you accidentally drop the door while lifting it DO NOT try to stop the door with your foot. A 300 pound wall dropping on your foot is going to ruin your day.

Step 2 – Identify Your Spring

Next identify which type of garage door spring you have: Extension or Torsion.

A torsion spring runs across a bar at the top of the inside of the garage door. The spring is wound and under immense tension. It’s the tension of the torsion spring that lifts the weight of the garage door.

Extension springs are on either side of the door, perpindicular to it. These springs act like big, steel rubber bands, stretching as the garage door is lowered. The natural tendency of the stretched spring is to lift the door.

Torsion and extension springs exert a force equal to the weight of your garage door. This counter balances the 200 to 300 pound garage door rendering it weight neutral so it can be easily opened. If your garage door springs break you can still manually open the door, you just need to exert that much more force to open it.

Step 3 – Buy New Springs

Now that you know what type of spring you have, you need to purchase new ones.

You’ll want to replace all of your garage door springs at the same time. Why? Typically garage door springs are installed at the same time. Having undergone similar aging and weathering, one broken garage door spring is a sign that the second one will soon break too. Of course you could wait until the other spring breaks but then you’ll need to go through the hassle of repairing a broken spring again. Additionally, having a new and old spring on your garage door throws off the balance of the door. You’ll quickly burn out the motor on your garage door opener and have more problems.

Where do you buy garage door springs? You can find them at your local hardware store such as Home Depot or Ace Hardware, or online. Prices will vary from a few dollars to over $150, depending on the type of spring, size, quality, coating, and cycles. The last three are important to consider as they will determine how soon your going to need to replace your springs again.

Size – You’ll need to measure your existing spring to know exactly what size replacement you’ll need. There are 4 measurements your going to need, and accuracy is important. They are: (1) Wind direction (2) The wire size (3) The diameter (torsion springs measure inside diameter, extension springs measure outside diameter) (4) The overall length of the spring. You can visit for a more detailed walk through on this part.

Quality – Are the springs produced in China, using inferior steel that is going to wear quickly? Or is the steel high quality that is going to last?

Coating – What kind of coating does the spring have? Is it galvanized, power coated, or oil tempered? Which is going to resist rust the longest? The image below shows 3 types of coating and the effect of salt spray on them over time. You can see that a powder coated spring is going to hold up the longest against the elements.

Something else to consider is that not all powder coatings are equal. Both of the springs shown below are brand new, however you can see the lower quality spring on the bottom has exposed steel where the coating is wearing off. This  spring is already vulnerable to rust and corrosion and it hasn’t even been installed yet.
