When Garage Door Springs Fail: The Dangers of Improper Installation
Hidden Dangers of Single Spring Garage Doors
Typical damage caused by a broken spring on a double-width door
As the owner of Same Day Garage Door Repair, I've seen countless spring failures, but sometimes what appears to be a simple spring replacement reveals deeper issues. When a customer called about a broken spring, I discovered three critical problems that needed immediate attention.
Most homeowners don't realize that when a garage door spring breaks, it can cause a cascade of problems. In this case, the customer was dealing with:
- A single spring on a double-width garage door (a significant safety hazard)
- A damaged top panel from the door's sudden fall when the spring broke
- Potential opener compliance issues with California safety regulations
The Initial Call
The conversation started with a simple question about spring replacement estimates, but quickly revealed a concerning situation:
Customer: "I think our spring broke on our garage door. I'm just calling to try to figure out, do you offer, like, free estimates to come assess what needs to be fixed?"
Larry: "Is it a two car garage?"
Customer: "I think so."
Larry: "Is there two springs above the door or what?"
Customer: "There's one."
Larry: "If it's a two car garage, it should have two springs. A two car garage would be a 15 or 16 foot wide door. A single car garage would only be eight foot wide."
Customer: "Oh, it's definitely wider than eight feet."
This exchange immediately identified the first major issue: a double-width garage door with only one spring. This is a serious safety concern, and I always recommend upgrading to a two-spring system.
The Hidden Damage
As our conversation continued, the customer revealed additional damage that wasn't mentioned initially:
Customer: "Because the spring broke, our door, like, fell down, obviously. And the top panel is bent now. I have a few pictures I can send, but I'm trying to figure out how we could fix the door to be straightened out."
Proper two-spring configuration (left) vs. unsafe single-spring setup (right) on a double-width door
This is extremely common with single-spring failures on large doors. When the only spring breaks suddenly, the door can fall with significant force. The top panel often bears the brunt of this impact, resulting in bent or damaged panels.
Why One Spring on a Double Door Is Dangerous
I always install two springs on larger doors for several important reasons:
- Safety redundancy: If one spring breaks, the second spring can still hold the door, preventing unexpected falls
- Extended lifespan: Two springs share the weight, reducing wear on each individual spring
- Accessibility during failure: You can still manually open the door if one spring breaks
- Prevention of secondary damage: Avoiding panel damage like what occurred in this case
Multiple Solution Options
With multiple issues to address, I laid out several potential approaches:
Larry: "Are you all you concerned about is just being operational? You don't care what it looks like?"
Customer: "I mean, yeah. I still want it to look decent, of course, but, yeah, operational."
Larry: "Well, to make it look decent, we would have to replace panels. If you wanna just make it so the door is sturdy again and you can open and close it, I could do that when I do the spring job. But I would have to come out and take a look at it if there's any more damage than just the springs."
I always present customers with options ranging from basic functionality to complete restoration:
California Safety Compliance
An important factor in the repair versus replace decision is California's building code requirements:
Larry: "Do you know if you have a battery backup garage door opener? The battery backup means you can open and close it when the power goes out. It has a battery that backs it up. That's actually required by California law. And if you replace either your top panel on your existing door or you replace it with a new door, you have to replace the opener if it isn't already a battery backup."
California SB-969: What Homeowners Need to Know
Since 2019, California law requires all new garage door opener installations to include battery backup systems. This law applies when:
- Installing a new garage door opener
- Replacing an existing opener
- In some jurisdictions, when replacing significant door components
Non-compliant installations can result in fines up to $1,000 per opener.
Why This Case Study Matters
This situation highlights several important aspects of garage door maintenance that every homeowner should understand:
- Proper spring configuration is essential for safety. Double-width doors should always have two springs.
- A broken spring can cause cascading damage. What starts as a spring issue can quickly lead to panel damage, track misalignment, and more.
- Code compliance matters. California's battery backup requirements add an important consideration to the repair vs. replace decision.
- Professional assessment provides options. While phone estimates are possible for common issues, seeing the full extent of damage in person allows for better solutions.
Immediate Response Is Key
One aspect of this case that demonstrates our commitment to customer service is how quickly we responded:
Larry: "I'm booked up, and I just happen to have a break in my day right now because I had a cancellation. So if you wanted me to take a look at it, I'd have to come over. You're in Walnut Creek, right?"
Customer: "Yeah, I am."
Larry: "I'd have to come over. I mean, I'm over on Main Street, right now. I pulled over at a Chevron before I went back to my shop just in case you wanted me to come over."
Being able to rearrange my schedule to provide same-day assessment means the customer doesn't have to wait with an inoperable garage door. Even if they choose not to proceed with repairs immediately, they have the information they need to make an informed decision.
Homeowner Tips
- Don't ignore spring condition. Have springs inspected annually to catch wear before catastrophic failure.
- Understand your door's configuration. Check if your door has the proper number of springs for its size and weight.
- Consider upgrading older systems. If your door has just one spring, upgrading to a two-spring system provides important safety benefits.
- Know the code requirements. If you're planning repairs or replacements, understand what local building codes require.
- Choose comprehensive solutions. Addressing only the broken component without considering the overall system can lead to repeated issues.
