A snapped garage door spring means your door won't open or close, and DIY fixes can be dangerous. The spring carries massive tension, so you should never attempt repairs yourself. Call a professional immediately, get a same-day estimate, and understand why this happened so you can prevent it next time.
Garage door springs fail because they wear out over time. A typical torsion spring lasts 7 to 9 years with normal use, depending on how often you open and close the door. If you're opening and closing your door 4 to 8 times daily, you're accelerating wear. See our guide on emergency garage door service in dunstable: what to do when yours fails.
Several factors speed up failure. Winter weather in Dunstable and nearby towns creates rust and brittleness. Lack of lubrication makes the metal inflexible. Poor installation or an undersized spring for your door's weight also contributes. Sometimes a spring simply reaches the end of its lifespan and gives out without warning.
The moment it snaps, you'll hear a loud bang or crack. The door becomes immovable. Don't force it. A snapped spring means the counterbalance system is broken, and manually lifting a heavy door risks injury or property damage. Read about garage door springs in dunstable: when to repair vs. replace.

Stop trying to use your garage door. If it's partially open, leave it as is. Don't attempt to pry it up or close it manually. The door could fall unexpectedly and cause serious injury.
If your car is trapped inside, use another exit and call a professional service. If you need immediate access for an emergency, contact us right away for a same-day response.
Next, take a photo of the broken spring if you can see it safely from inside the garage. Document when you last remember the door working normally. This information helps our technicians prepare the right replacement parts and give you an accurate cost estimate before we arrive.
Keep children and pets away from the garage door. A snapped spring is not a DIY project. Extension springs and torsion springs both operate under extreme tension. Touching or attempting to adjust them without proper training and tools can result in serious injury or death. We've been on trucks for 15 years, and we've seen what happens when homeowners try to cut corners on spring work.

Most snapped springs require full replacement rather than repair. Learn more about when to repair versus replace your springs to understand your options. If you want details on how springs work and why they fail, we've covered that in our types and how they work guide.
Our technician will inspect both springs, even if only one snapped. Often, if one spring fails, the other is close behind. Replacing both at once saves you money and prevents a second emergency call in a few weeks.
The job takes 1 to 2 hours depending on your door's setup. We'll remove the old spring safely, install a new one rated for your door's weight, and test the door thoroughly. We also lubricate the new spring to extend its lifespan.
Cost varies based on spring type and your door's size. Extension springs are less expensive than torsion springs. A professional replacement typically ranges from $250 to $500 per spring, including labor. Get a free estimate by calling us or visiting our contact page to schedule a free quote.
Once your door is fixed, maintain it properly. Lubricate your springs every 3 months with a silicone-based garage door lubricant. Keep the tracks clean and aligned. Check the door's balance monthly by disconnecting the opener and manually lifting the door partway. It should stay in place, not drift up or down.
Replace springs before they snap if you notice squeaking, slow operation, or if your door is over 8 years old. Proactive replacement costs less than emergency service and keeps your garage functioning reliably.
A snapped spring is stressful, but it's fixable. Call us today at (978) 338-7441 to get a same-day estimate and schedule service. We'll have your door working safely again.
Can I use my garage door if one spring is broken? No. A broken spring removes the counterbalance. The door becomes too heavy to lift safely, and the opener may be damaged if you force it. Call a professional immediately.
How long does spring replacement take? Most replacements take 1 to 2 hours. We arrive within a few hours of your call for same-day service in Dunstable and nearby areas.
Is spring replacement covered by warranty? Yes. We provide a warranty on parts and labor. Details vary by job, so ask your technician for specifics when we arrive.
Why do garage door springs fail in winter? Cold temperatures make metal brittle. Salt and moisture from roads accelerate rust. Combined with years of use, springs are more likely to snap during winter months.
Can I replace just one spring? Technically yes, but both springs wear together. If one snapped, the other is near the end of its life. Replacing both now prevents a second emergency call in weeks.
