In our years serving Boone, we've seen this problem again and again: a homeowner hears a loud bang, tries to open the garage door, and nothing happens. A snapped spring isn't always a reason to replace your entire system. The choice between repair and replacement depends on age, spring type, and whether one or both springs are compromised.
Most residential garage doors in Boone use one of two spring types: torsion springs or extension springs. Torsion springs sit above the door and wind tight to lift the weight. Extension springs run along the sides of the door and stretch to assist the opener. Both types handle roughly 10,000 cycles (that's about 7 to 9 years for an average household) before wearing out.
A single snapped spring doesn't mean instant total failure. If you have two springs and one breaks, the door is harder to open but not impossible. However, operating a garage door on one spring puts stress on your opener motor and can damage the door itself over time.
Here's where the math gets important. If your door has two springs and one breaks, replacing just that one creates an imbalance. The remaining spring does more work, wears faster, and likely fails within months. You'll end up paying for two repairs instead of one.
That's why we recommend replacing both springs at the same time, even if only one snapped. It costs more upfront, but you're protecting your investment. Think of it as matching tires on a car: one worn tire affects the whole system.
If your door originally had a single spring and it snaps, replacement is straightforward. Just install a new one of the same type and rating.

The cost to replace garage door springs varies based on spring type and whether you're replacing one or two. Extension springs typically cost less than torsion springs because they're simpler to install. Learn more about typical pricing in our detailed cost breakdown.
If your door is older than 7 years and shows other wear signs (rust on springs, slow operation, noisy movement), a full system evaluation makes sense. Sometimes a complete door replacement offers better value than pouring money into aging components.

Repair (not replacement) is the right call in these situations:
Single spring failure on a newer door. If your garage door is under 5 years old and only one spring broke due to a defect, replacing just that spring is reasonable.
Visible damage but no snap yet. Sometimes springs show rust, corrosion, or minor cracks. Replacing them before they snap avoids the emergency situation entirely.
Extension spring issues. If one extension spring loses tension but hasn't fully snapped, a technician can sometimes adjust or replace it as a single unit.
However, if your door is approaching replacement age anyway, read about when replacement makes more sense before spending money on springs alone.
Garage door springs carry enormous tension. A torsion spring under load has enough force to cause serious injury or death if it releases suddenly. We've seen too many homeowners in Boone try YouTube fixes and end up hurt.
This isn't about being careful or handy. It's physics. Springs need special tools, safety cables, and professional knowledge to handle correctly.
If your spring snapped:
1. Don't force the door open or closed. 2. Stop using the garage door immediately. 3. Call a professional for same-day inspection.
We'll examine both springs, check your opener, and give you an honest estimate. Some jobs need both springs replaced. Others don't. Either way, you'll know exactly what you're paying for and why.
The garage door springs in Boone homes work hard in temperature swings and humidity that accelerates wear. Replacing them proactively keeps your door safe, quiet, and reliable for years. Browse our full spring services to see what we offer.
How do I know if my spring is broken? A loud bang followed by the door becoming very heavy to open is the classic sign. You might also see the garage door sagging unevenly or hanging crooked. Don't try to force it; call a professional to diagnose the problem safely.
Can I use the garage door with a broken spring? Technically yes, but it puts strain on your opener motor and can damage the door. The opener wasn't designed to lift the full door weight alone. Using it this way risks more expensive repairs down the road.
How much does a garage door spring replacement cost near me? Cost ranges from $200 to $400 per spring depending on type and installation. Dual spring replacement typically costs $400 to $800. Get a free estimate specific to your door and we'll explain exactly what you're paying for.
How long do garage door springs last? Most springs last 7 to 9 years with normal use (about 10,000 cycles). Boone's weather and temperature changes can shorten that lifespan. Springs in climate-controlled garages sometimes last longer.
Should I replace one spring or both? If you have dual springs and one snaps, replace both at the same time. This keeps the door balanced and prevents the second spring from failing prematurely due to uneven load distribution.
