Snapped Garage Door Springs in Longmont: Why DIY Fixes Cost More
2026-08-02 7 min read
A snapped garage door spring means your door won't budge, and that emergency feeling tempts many Longmont homeowners to grab a wrench and DIY. Don't. A single broken spring requires professional replacement, costs $150 to $400 depending on spring type, and attempting it yourself can cause serious injury or damage costing far more.
What Happens When a Spring Snaps
Your garage door weighs 300 to 500 pounds. Two springs (torsion or extension style) balance that weight so your opener can lift it smoothly. When one snaps, the other can't hold the load alone. Your door becomes immovable, or it slams down suddenly, risking injury and property damage.
You'll notice the problem instantly. The door won't open at all, even with the opener running. You might hear a loud bang or pop before it happens. Both torsion and extension springs fail eventually. Springs in Longmont typically last 7 to 9 years with normal use, though seasonal temperature swings and humidity can shorten that lifespan.
Why You Shouldn't DIY Spring Replacement
Springs store enormous tension. Unloading that tension without proper tools can snap back and break bones or lacerate skin. Professional technicians use specialized equipment and training. They also inspect the rest of your door system while they're there, catching problems before they become expensive.
If you try to replace a snapped spring yourself and fail, you'll still call a pro. You'll pay the full service cost plus potential damage repair. That's how a $250 job becomes a $500 one. Beyond safety and cost, DIY attempts often void any existing warranty on your door or opener.

Torsion vs. Extension Springs: Which One Failed
Torsion springs sit above your door on a metal rod. They twist to store and release energy. Extension springs hang on either side of the door track and stretch to balance the weight. Both types can snap, but the cause differs slightly.
Torsion springs fail from metal fatigue. The constant coiling and uncoiling creates tiny stress fractures that eventually snap. Extension springs wear out faster if the pulleys are misaligned or rusty. Knowing which type you have helps you communicate with a technician and understand the estimate.

What a Professional Replacement Includes
When you call Garage Door Longmont or another reputable local company, a technician will arrive within hours for emergency calls. They'll inspect both springs, even if only one snapped. Sometimes the second is close behind. They'll also check the door balance, cables, and pulleys. A complete replacement typically takes 30 to 60 minutes.
A fair estimate includes labor, the springs themselves, and a brief safety check. Avoid quotes that seem unusually cheap. Springs come in different gauges and lengths. Using the wrong specification creates an unbalanced door that wears out other components faster.
If your door has been limping along with a broken spring for days, expect potential damage to the cables or tracks. The technician will flag those issues and provide a separate estimate if needed. This transparency prevents sticker shock later.
Same-Day Service and Cost Savings
Longmont homeowners often ask if they can wait for a cheaper appointment. The answer depends on how long you can live without garage access. If you need your door working today, emergency same-day service costs 20 to 40 percent more than a scheduled appointment. Booking ahead saves money and stress.
Regular maintenance reduces spring failures. A tune-up every 12 months catches worn springs before they snap, giving you time to schedule replacement when it fits your budget. Learn more about preventive maintenance and how it saves on costly repairs.
Next Steps: Get an Estimate
Don't assume all repair shops charge the same. Call three local Longmont technicians, describe your snapped spring, and compare estimates. Ask if the price includes both springs or just the broken one. Ask about warranty on parts and labor. A trustworthy company will answer every question.

Frequently Asked Questions
How long can I drive with a snapped garage door spring? You can't drive in or out safely. A broken spring leaves the door stuck or prone to sudden drops. Don't attempt to manually lift it or prop it open. Call for professional repair same-day to restore access.
Can I replace just one spring if both are old? Technically yes, but it's shortsighted. If one spring is worn enough to snap, the other is near failure. Replacing both at once costs only slightly more and saves you a second emergency call within weeks.
What's the average cost to replace garage door springs in Longmont? Torsion springs run $150 to $300 per pair. Extension springs cost $100 to $200 per pair. Labor adds $100 to $200. Total estimates typically fall between $250 and $400 for same-day emergency service.
Do I need a new door if the spring snapped? No. The spring failure itself doesn't damage the door panels. However, if the door fell hard or cables frayed, you may need cable replacement. A professional inspection identifies the true scope of damage.
Is spring replacement covered by homeowner's insurance? Most homeowner policies don't cover spring replacement as a maintenance issue. Check your policy or ask your agent. Emergency repair coverage varies, so clarify before an incident happens.
