Garage Door Spring Replacement in Onset, MA: What to Know Before You Call
2026-04-12 7 min read
If you've ever walked into your garage on a cold January morning only to find your door won't budge, there's a good chance your spring finally gave out. It's one of the most common garage door failures we see in Onset. and in nearby Wareham and Bourne. especially after a rough winter season on Buzzards Bay. The good news is that spring replacement is a well-understood repair with predictable costs. The bad news is that it's genuinely dangerous to attempt on your own.
Here's what every Onset homeowner should understand before picking up the phone.
Why Springs Fail Faster Here
Onset's location as a historic Victorian waterfront village on Buzzards Bay creates a uniquely harsh environment for garage door hardware. The community has over 54 miles of coastline nearby, and that coastal exposure means your springs are dealing with salt air, high humidity, and the mechanical stress of temperature swings. all at once.
The area is no stranger to serious weather events either. Wareham has experienced repeated nor'easters that bring coastal flooding, high winds, and structural stress to homes throughout the region. Each time temperatures drop sharply after a storm, metal components react.
Torsion springs and extension springs both suffer in these conditions. Cold weather causes the metal to contract and become brittle, increasing the likelihood of a snap under load. Meanwhile, the coastal humidity accelerates corrosion on unlubricated or uncoated springs. even ones that aren't visibly rusted yet.
If your door is more than seven years old and you haven't had the springs inspected, it's worth having someone take a look. You can also check out our post on signs your garage door needs professional repair to know what else to watch for.
How to Tell Your Spring Is Failing
Springs don't always snap dramatically. Sometimes the warning signs are subtle. Here's what to look for:
The door feels extremely heavy
Disconnect the automatic opener and try lifting the door manually. A properly balanced door with functioning springs should feel relatively light. maybe 10 to 20 pounds of resistance. If it feels like you're lifting the whole door yourself, the spring is losing tension or has already failed.
Visible gaps in the coil
For torsion springs (mounted horizontally above the door opening), look for a visible gap in the coil. A gap means the spring has snapped. For extension springs (running along the tracks on either side), look for a spring that appears stretched out or sagging.
The door opens unevenly
If one side of your door rises faster than the other, or the door tilts noticeably during operation, a spring on one side may be weaker than the other. This creates uneven tension that can damage cables, rollers, and the opener motor over time.
Loud bang from the garage
A sudden loud bang. often described as a gunshot sound. coming from a closed garage is almost always a torsion spring snapping under tension. If this happens, don't try to operate the door.
Torsion vs. Extension Springs: What's the Difference?
Torsion springs are mounted horizontally above the door. They're more durable, last longer, and are generally considered safer because they stay contained on the rod when they break. Most newer doors and heavier double-car doors use torsion springs.
Extension springs run along the sides of the door tracks and work by stretching. They're common on older Onset cottages and lighter single-car doors. They're less expensive to replace, but they carry a higher safety risk. a broken extension spring can fly across the garage with significant force if safety cables aren't in place.
For homes along Onset's older neighborhoods, many with original cottage-era construction, it's worth asking a technician whether your current spring setup is still appropriate for the door.
What Does Spring Replacement Cost in Onset?
For a standard single-car garage door, spring replacement typically runs between $150 and $350 per spring, with most homeowners paying around $250 on average including labor. For a double-car door or heavier custom door, costs can run higher. often $300 to $540 or more with professional installation.
A few things that affect your final price in this area:
- Spring type: Torsion springs cost more than extension springs but last longer. typically 8 to 15 years versus 7 to 12 years for extension springs - Replacing both at once: Professionals always recommend replacing both springs simultaneously, even if only one has broken. The second spring has the same wear history and will typically fail shortly after the first - Corrosion damage: In coastal environments like Onset, springs that have corroded may require cable replacement as well, adding to the total - Emergency service: If your spring breaks at night or on a weekend, expect an additional fee for after-hours service
If you're replacing springs on an older door, it's also a good time to assess whether other components need attention. Our guide on common garage door services covers what a full tune-up typically includes.
Why This Is Never a DIY Job
Garage door springs are under enormous tension. enough to cause serious injury if mishandled. Torsion springs in particular require specialized winding bars and careful calibration. Attempting to replace them without the right tools and training has sent homeowners to the emergency room.
Beyond the physical risk, incorrect spring sizing will cause the door to operate improperly, putting extra stress on the opener motor and potentially voiding any existing warranty. This is one of those repairs where the cost of hiring a professional is genuinely worth every dollar.

Frequently Asked Questions
Q: Can I still use my garage door if a spring is broken? A: Technically the door may still move, but you shouldn't use it. Operating the door with a broken spring puts enormous strain on the opener motor and can burn it out. It also creates a safety hazard. the door could drop unexpectedly. Leave the door closed and call a technician.
Q: How long do garage door springs typically last? A: Most springs are rated for 10,000 cycles. For a family that opens and closes the garage door four times a day, that works out to roughly seven to ten years. In coastal environments like Onset, where humidity and salt air accelerate corrosion, springs may fail on the earlier end of that range. especially if they haven't been lubricated regularly.
Q: Should I replace both springs even if only one broke? A: Yes, and any reputable technician will tell you the same thing. Both springs were installed at the same time and have experienced the same wear. When one breaks, the other is usually close behind. Replacing both now saves you a second service call. and a second labor fee. in a matter of months.
