Garage Door Springs in Killingworth: Cost, Repair, and When to Replace
2026-05-13 7 min read
In our years serving Killingworth, we've seen this problem again and again: homeowners hear a loud bang from the garage, and suddenly the door won't open. A snapped torsion spring is usually the culprit. The good news is that replacing garage door springs in Killingworth is straightforward and affordable when you call a professional. The bad news is that DIY attempts often end in injury or worse damage to your door system.
Why Garage Door Springs Fail
Your garage door weighs between 300 and 500 pounds. Two springs (or sometimes one heavy-duty torsion spring) support that entire load, opening and closing thousands of times over their lifespan. Springs last about 7 to 9 years under normal use, though they can fail sooner if your garage is unheated or if you open and close the door excessively.
Over time, metal fatigue weakens the coils. Temperature swings in Connecticut winters accelerate this wear. When a torsion or extension spring finally snaps, the door becomes immobile, and the opener motor strains against the full weight of the door. That's when you'll hear that unmistakable bang.
Types of Garage Door Springs and Their Cost
Most residential doors use one of two designs: torsion springs or extension springs.
Torsion springs sit above the door and twist to lift it. They're more durable, safer, and last longer than extension springs. Replacing a torsion spring typically costs $150 to $300, depending on the spring's weight and your door's size.
Extension springs run along the sides of the door track and stretch to open it. They're cheaper to replace (around $100 to $200 per spring) but wear out faster. You'll often need both springs replaced at the same time, even if only one has snapped. This prevents imbalance and premature failure of the remaining spring.

Why You Should Never DIY Spring Replacement
Springs are under extreme tension. A snapped spring can snap back with lethal force. Even experienced DIYers have been seriously injured trying to replace them. The torsion winding cone can crush fingers or hands in seconds.
Your garage door opener also isn't designed to work without functioning springs. Running it with a broken spring burns out the motor and gearbox, turning a $200 repair into a $500 replacement. We've replaced countless openers damaged this way.
A licensed technician has the right tools, knowledge of your specific door model, and insurance to protect you. When you schedule a free quote with Killingworth Garage Doors, we'll inspect both springs and give you an honest estimate before we touch anything.

Prevention and Maintenance
While springs will eventually wear out, you can slow the process. Keep your garage at a consistent temperature during winter. Lubricate the springs lightly with a silicone-based garage door lubricant once a year. Test your door's balance monthly by opening it halfway and letting go. If it drifts, your springs need attention soon.
Also, have your door inspected annually. Small problems caught early prevent expensive emergency repairs. Check out our full services page to learn more about spring maintenance options we offer.

Frequently Asked Questions
How long do garage door springs last? Most springs last 7 to 9 years with normal use. Frequency of opening and closing, garage temperature, and spring quality all affect lifespan. If you open your door 10 or more times daily, expect shorter life.
Can I replace just one spring if both are old? Not recommended. If one spring has failed, the other is likely near the end of its life. Replacing both at once prevents a second failure weeks later and keeps your door balanced and safe.
