If you've ever heard a loud bang from your garage early in the morning and walked out to find your door frozen in place, you've probably experienced a broken garage door spring. It's one of the most common calls we get here in Falmouth. and one of the most misunderstood repairs homeowners face. Springs aren't glamorous, but they do virtually all the heavy lifting. When they fail, everything stops.
Falmouth's coastal climate makes this issue more pressing than it is in most of Massachusetts. The salt air rolling in off Vineyard Sound and Buzzards Bay, combined with the area's consistently high humidity, accelerates corrosion on metal components. especially springs. Homes in neighborhoods like Woods Hole, Sippewissett, and along the East Falmouth waterfront deal with this year-round. Even inland areas near Waquoit Bay or the freshwater ponds of North Falmouth see enough moisture cycling to shorten spring life noticeably.
Your garage door. whether it's a single-car Cape Cod cottage door or a double-wide on a newer colonial in Teaticket. typically weighs between 150 and 300 pounds. Springs counterbalance that weight, making it possible for your opener (or your own arm) to lift the door with minimal effort.
There are two main types:
Torsion springs mount horizontally above the door opening and twist to store energy. They're the modern standard. safer, smoother, and longer-lasting. Most doors installed in the last 15 years use them.
Extension springs run along the sides of the door tracks and stretch as the door closes. They're more common on older doors and generally less expensive, but they have a shorter lifespan and can be more dangerous when they snap.
If your home was built in the 1970s or 80s. common in West Falmouth's historic district along Route 28A. there's a decent chance you still have the original extension spring setup.
Springs rarely give out all at once without any warning. Here's what to watch for:
- The door feels unusually heavy when you lift it manually. A properly balanced door should feel like it weighs about 10 to 15 pounds. - The door won't stay open when lifted halfway. Release it at mid-height. it should stay put. If it drifts down, the springs are losing tension. - Visible gaps in the torsion spring coil. Healthy coils sit tight against each other. A gap means the spring has snapped under tension. - Loud popping or squeaking during operation, especially in cold or damp weather. - The opener motor runs but the door doesn't move. or barely moves. - Rust or visible corrosion on the spring coils. In Falmouth's salt air environment, this is something to check at least once a year.
If you notice rust developing, don't ignore it. Coastal humidity accelerates corrosion on steel springs, which weakens the metal and leads to premature failure. A light application of lithium-based lubricant a few times a year. especially heading into winter. can meaningfully extend spring life.

This is where we have to be straight with you: garage door spring replacement is genuinely dangerous, and it's one of the few repairs where we strongly recommend against DIY for most homeowners. Torsion springs are wound under hundreds of pounds of tension. If one releases suddenly during handling, it can cause serious injury. Professional technicians use calibrated winding bars and follow strict safety protocols that aren't easy to replicate at home.
The small amount you'd save on labor isn't worth the risk. This isn't the same as replacing a light switch or patching a hole in drywall.
Costs vary depending on the type of spring, the size and weight of your door, and whether additional components need attention. Here's a realistic range:
- Extension springs: $100,$200 per spring, including labor - Torsion springs: $150,$350 per spring, including labor - Both springs replaced together (single door): $200,$500 total
One thing worth knowing: it's almost always smarter to replace both springs at the same time, even if only one has broken. Springs age together. If one fails, the other is usually close behind. Replacing both in a single visit saves you another service call. and another round of being stuck with a door that won't open.
If your spring failure has also damaged cables or tracks (which sometimes happens when a spring snaps suddenly), that can push costs higher. Check out our panel repair guide if you're also dealing with door panel damage from the impact.
For homes with heavier doors. like solid wood carriage-style doors that are popular in some of Falmouth's more upscale neighborhoods, or insulated steel double doors. expect to pay toward the higher end of those ranges due to the stronger springs required.
If your springs are original to a door that's 10 or more years old, this is a good time to ask about high-cycle springs. Standard springs are typically rated for 10,000 cycles. High-cycle options can last 25,000 to 50,000+ cycles and hold up better in humid coastal conditions. The upfront cost is modestly higher, but you'll likely get significantly more years out of them. and fewer emergency calls.
Also worth discussing with your technician: if you're currently using extension springs on an older door, this might be a good moment to consider converting to a torsion system. It's a larger investment (typically $400,$800 for the conversion), but torsion springs are safer, smoother, and better suited to the damp conditions in Falmouth and neighboring towns like Mashpee and Barnstable.
Garage Door Falmouth offers spring inspections, same-day replacement service, and honest advice on whether an upgrade makes sense for your specific door. If you're not sure what you're dealing with, contact us for an assessment before the spring fails completely.
Q: How long do garage door springs typically last in Falmouth's coastal climate? A: Standard springs are rated for about 10,000 cycles, which translates to roughly 7,12 years under normal use. In Falmouth's salt air and high-humidity environment, springs that aren't regularly lubricated may fail sooner. High-cycle springs can last 15,20+ years even in coastal conditions.
Q: Can I still use my garage door if a spring is broken? A: Technically the opener may try to run, but you shouldn't use it. Operating the door with a broken spring forces the motor to lift the full unbalanced weight of the door, which can burn out the motor and cause additional damage. Disconnect the opener and call for service.
Q: Do I really need to replace both springs if only one broke? A: In almost every case, yes. Both springs age at the same rate. If one snaps, the other is likely near the end of its life as well. Replacing both in one visit saves you money and avoids being stranded again in a matter of months.
