In our 15 years serving Cohasset, we've seen this problem again and again: a homeowner opens the garage one morning, hears a loud *snap*, and suddenly the door won't open or move. A broken spring is almost always the culprit. The good news? It's fixable fast. The bad news? It's not a DIY job, and waiting makes it worse.
Springs don't just fail randomly. They're under constant tension, holding roughly half the weight of your door (often 300 to 500 pounds). Most residential springs last between 7 and 9 years, depending on how often you use the garage.
When a spring breaks, it's usually because:
- Wear and tear from cycles. Every time you open and close the door, the spring flexes. After thousands of cycles, metal fatigues and snaps. - Rust and corrosion. Here on the South Shore, salt air accelerates rust. A corroded spring weakens faster than a clean one. - Lack of lubrication. Dry springs work harder and fail sooner. This is why garage door lubrication and maintenance matters so much for Cohasset homeowners. - Temperature swings. Massachusetts winters and summers stress metal differently. Contraction and expansion over decades adds up.
A broken spring is a safety issue. The door becomes a 400-pound dead weight. The opener can't lift it, and the door can fall suddenly.
You don't need a technician to know something's wrong. Look for these red flags:
- The door won't open, even when the opener runs. - The door opens partway, then stops. - You hear a loud *crack* or *snap* from the garage. - The door feels unusually heavy when you try to lift it manually. - One side of the door hangs lower than the other.
If any of these happen, stop using the door. Call us right away. Forcing a broken spring system damages the opener and tracks, raising your repair cost significantly.

When you call Cohasset Garage Doors for a broken spring, here's what to expect.
First, we'll troubleshoot the door to confirm the spring is actually broken (sometimes it's the opener or a sensor issue). We'll inspect both springs, even if only one snapped, because the second one is likely close behind.
Then we replace the broken spring with a new one rated for your door's weight and cycle count. We don't cheap out on parts here. A quality spring costs more upfront but lasts longer and fails less often. We also lubricate everything while we're in there, which extends the life of the new spring.
The whole job typically takes one to two hours. Same-day service is usually available if you call before noon.
For pricing, spring replacement costs vary. A single spring replacement might run $200 to $400, depending on the type and quality. If both springs need replacing (which we often recommend), expect $400 to $700 total.

I'll be direct: replacing a garage door spring is dangerous. The springs are under extreme tension. If you slip, the spring can unwind violently and cause serious injury or death. We've seen it happen.
Unless you have professional equipment and training, leave it to us. The cost of a professional repair is far less than an emergency room visit.
You can't stop springs from aging, but you can slow it down.
Lubricate your door tracks and springs twice a year (spring and fall). Use a silicone-based garage door lubricant, not WD-40. This reduces friction, keeps rust at bay, and extends spring life by a year or more.
Also, minimize unnecessary cycles. Don't open and close the door "just to see" if it works. Every cycle counts toward the spring's lifespan.
If your garage door is more than 8 years old and you haven't replaced the springs yet, it's worth having us inspect them. We can tell if they're near the end of their life and plan ahead rather than dealing with an emergency.
A broken spring isn't an inconvenience you can ignore. It's a safety hazard and a stuck door. The sooner you get it fixed, the better.
We service all of Cohasset and the surrounding South Shore communities. Our technicians carry springs in the truck, so most repairs are completed the same day you call. If you notice your door is stuck or not working, don't wait.

Q: Can I open my garage door if the spring is broken? A: No. Do not force it. A broken spring means the door is too heavy for the opener or your hands. Forcing it risks damage to the opener, tracks, and your safety. Call for repair immediately.
Q: How much does a broken spring repair cost? A: A single spring replacement typically runs $200 to $400. Both springs usually cost $400 to $700. Exact pricing depends on the spring type and your door's weight. We provide free estimates.
Q: How long do garage door springs last? A: Most residential springs last 7 to 9 years with normal use (about 3 to 5 cycles per day). Frequent use, rust, and lack of lubrication shorten this timeline significantly.
Q: Is it safer to replace both springs at once? A: Yes. If one spring has failed, the other is likely near failure. Replacing both at once prevents a second breakdown weeks later and balances the door load evenly.
Q: Can I prevent spring failure? A: Lubricate your door twice yearly with silicone-based lubricant, minimize unnecessary cycles, and have springs inspected annually if your door is over 8 years old.
