When your garage door won't open and you hear a loud crack from above, a snapped spring is usually the culprit. Repair costs in Thornton typically run between $150 and $400 per spring, depending on the type, your door's weight, and whether you need same-day service. The good news? Understanding what drives that cost helps you avoid overpaying.
Not all springs cost the same, and that's where many homeowners get blindsided by estimates. The two main types are torsion springs (mounted horizontally above your door) and extension springs (running along the sides). Torsion springs usually cost more to replace because they're under higher tension and require specialized tools and expertise.
Your garage door's weight matters too. A heavy insulated door needs heavier-duty springs, which cost more than springs for a standard single-car door. A two-car door with an extension spring might cost $180 to $250 per spring, while a torsion spring on that same door could hit $300 to $400.
Labor is another factor. If you call for same-day service on a weekend or evening, expect to pay a premium over a standard weekday appointment. Installation typically takes one to two hours per spring.
Torsion springs are the heavy lifters of garage door systems. They're wound tightly and store enormous energy, which makes them efficient but also expensive to replace. A single torsion spring repair in Thornton usually costs $250 to $400 installed. These springs last 7 to 9 years with normal use, so if yours has snapped, it's time to plan for the second one soon. Most doors have two torsion springs working together, so budget accordingly.
Extension springs are cheaper to replace individually, running $150 to $250 per spring. They're simpler mechanically but require safety cables to prevent injury if they break. If one extension spring snaps, the other is likely near the end of its life too. Replacing both at once saves you a second service call down the road.
Before you commit to any repair, get a free estimate from someone who knows Thornton's climate. Winter weather puts extra stress on springs, and Colorado's dry air can accelerate wear.

The cheapest spring repair is the one you prevent. Regular maintenance catches small problems before they become expensive replacements. Lubricate your springs and hinges every three months with a garage door specific lubricant. A stuck or squeaky door is telling you something needs attention.
If both springs are old, replacing them together is smarter than replacing one now and the other in six months. You'll pay a single service fee instead of two. Our guide on signs your garage door springs need replacement walks you through what to look for.
Also, avoid the temptation to DIY spring repair. Garage door springs are under extreme tension and can cause serious injury or death if mishandled. A professional can schedule a free quote and handle it safely in under two hours.
A solid estimate breaks down parts, labor, and any additional repairs your technician finds. Never accept a vague quote. Ask specifically whether the estimate covers both springs (if applicable), the safety cables, and hardware. Some shops charge extra for disposal of old springs.
If you're comparing quotes from multiple companies, make sure they're quoting the same type of spring and service level. A $150 quote might not include safety cables, while a $300 quote does.

A snapped spring means your garage door won't open, and you're stuck. Waiting longer won't lower the cost. In fact, driving your door on a single working spring (if you have two) stresses the opener and tracks, leading to bigger repair bills.

How long do garage door springs last? Torsion and extension springs typically last 7 to 9 years with normal use. That's roughly 10,000 to 15,000 open-close cycles. Frequent use or harsh weather can shorten that lifespan.
Can I replace just one spring if both are old? Technically yes, but it's not budget-smart. If one spring has snapped, the other is near failure. Replacing both at once saves you a second service call and labor fee within months.
Is spring repair cheaper than buying a new garage door? Yes, by far. Spring repair costs $150 to $400 per spring. A new garage door runs $1,500 to $4,000 installed. Spring repair is always the economical choice.

Why is my spring repair quote so high compared to another shop? Different shops use different quality parts and labor rates. Make sure quotes include the same components (safety cables, hardware, disposal) and spring type before comparing prices.
