A loud bang from the garage, a door that won't lift, or an opener that strains and stops. Often that points to a broken spring. Springs hold the weight of the door, so they carry a lot of stored force.
Ponhap Garage Doors is a referral service. We don't repair springs. We connect Walnut Creek homeowners with independent providers in our network who do. This page covers safe first steps, what a repair visit looks like, typical costs, and the questions to ask before you say yes.
Broken Spring? Stop, Then Check
First, breathe. A broken spring looks scary, but it is rarely dangerous if you leave it alone. Don't try to force the door. Don't stand under it.
Here is the safe short list:
- Keep kids and pets out of the garage.
- Don't run the opener again.
- Don't touch the springs, cables, or the brackets at the bottom of the door.
- Move any car only if the door is fully closed or fully open and steady.
Hands off springs. That is the one rule to remember.
How to Tell if a Spring Is Broken
You can check a lot without touching anything. Look and listen.
- You heard a sharp bang, like a dropped tool, from the garage.
- The door lifts only a few inches, or not at all.
- The opener hums and strains, then quits.
- You see a gap in the coil above the door (torsion) or a stretched, loose spring along the side tracks (extension).
- The door feels very heavy if you release it and lift by hand.
- The cables hang loose or look bunched at the drum.
If you see two or more of these, treat the spring as broken. Don't test it further.
Can You Still Get the Car Out?
Maybe. Many openers have a red emergency release cord. But with a broken spring, a door that is released can be heavy and may drop fast. Don't pull the cord if the door is up. If the door is down and you must get out, ask a provider how to proceed safely. Waiting a short while is usually better than a hurt back or a bent door.
Torsion Springs vs. Extension Springs
Knowing your type helps you describe the problem on the phone.
Torsion springs
These sit on a bar above the closed door. They twist to lift it. Many 1950s to 1980s tract homes have been upgraded to these, and most newer doors use them.
Extension springs
These run along both side tracks. They stretch and shrink as the door moves. Older bungalows and ranch garages often have them. They need safety cables so a snapped spring doesn't whip around.
Whichever type you have, the force is high. Both are provider jobs.
Why You Shouldn't Replace Springs Yourself
I like a good weekend fix as much as anyone. This is not one of them. Winding bars slip. Wrong-size springs make the door unbalanced. Hardware stores sell parts, but the sizing depends on door weight, height, and drum type.
Hurt hands and broken teeth are the usual results of a slip. So skip it. Save your DIY energy for the safe jobs below.
What You Can Safely Do While You Wait
- Take a clear photo of the spring area and the door label if you can see it from the floor.
- Note the door size, width and height, if you know it.
- Write down what you heard and saw.
- Clear boxes and bikes from the door's path.
- Check your home insurance. Some policies may cover sudden damage; check your policy.
What a Spring Replacement Visit Includes
A typical visit follows a set order. Expect a provider to:
- Inspect the door, balance, cables, and rollers.
- Release and remove the broken spring in a safe way.
- Match the new spring to the door weight and size.
- Install and wind the spring, and tighten the hardware.
- Lubricate moving parts and test the balance.
- Check track alignment and the opener while on site.
Most springs come in pairs on wide doors. Many providers replace both at once, since the second is often close to the end of its life.
Standard vs. High-Cycle Springs
A standard spring is rated for roughly 10,000 open-and-close cycles. A high-cycle spring is rated for more. If you use the door many times a day, a longer rating may fit better. It costs more up front, so ask for both prices.
Dry heat and coastal air can wear coatings over time. A light coat of lubricant helps either type.
Questions to Ask the Provider
A good provider answers plainly. Ask these:
- What spring type and size will you install, and what is its cycle rating?
- Is the price per spring or for the pair?
- Does the quote include labor, parts, and a trip charge?
- Will you check the cables, rollers, and track alignment?
- Is there a warranty on parts and labor, and is it in writing?
Quote in writing. If the answer is vague, move on.
Red Flags
- A price that jumps after the visit starts.
- Pressure to replace the whole door when only a spring broke.
- No clear answer on spring size.
- A refusal to put the quote on paper.
After the Repair
Test the door by hand once the provider is done. It should stay halfway when lifted and released. If it drifts up or slams down, tell the provider right away. Keep the invoice and warranty for your records.
What's Included
Safe Removal of Old Spring
The provider releases the stored tension in a controlled way and takes out the broken spring.
Right-Size New Spring
Spring size is matched to your door's weight, height, and drum type.
Cable and Roller Check
Worn cables and rollers get inspected so the new spring is not stressed.
Balance and Track Test
The door is tested for smooth, even travel, including track alignment.

Garage Door Spring Repair FAQ
How do I know if my garage door spring is broken?
Common signs are a loud bang, a door that won't lift, an opener that strains, or a visible gap in the coil. Don't test the door further. Keep people clear and contact a provider.
Is it safe to open a garage door with a broken spring?
It is not a good idea. The door can be very heavy and may fall without warning. Avoid using the opener or lifting it by hand, and wait for a trained provider.
How long do garage door springs last?
Standard springs are often rated around 10,000 cycles, which may be several years of normal use. Heavy daily use wears them faster. A provider can suggest a higher-cycle spring if needed.
