In our 15 years serving Marlborough homeowners, we've fielded this question more times than I can count: "What kind of springs does my garage door have?" The answer matters because torsion and extension springs work differently, fail differently, and cost different amounts to replace. Get it wrong, and you'll overpay or end up with a door that won't operate safely.
Most modern garage doors in Marlborough use torsion springs. These springs sit horizontally above your door opening, wound tightly like a clock spring. When you open the door, the spring unwinds to counterbalance the weight. When you close it, the spring winds back up.
Torsion springs are engineered precisely for your door's weight. A typical residential door weighs 300 to 500 pounds. The spring's diameter, wire gauge, and number of coils all factor into how much lift force it provides. Manufacturers rate them in cycles, not years. A standard spring lasts about 7 to 9 years with normal use, which translates to roughly 10,000 to 15,000 open/close cycles.
Here's the key: if your spring snaps, the door becomes a dead weight. You won't be able to operate it manually without significant effort. This is why a snapped spring is an emergency situation.
Extension springs run along both sides of your door opening, stretching and contracting as the door moves. They're less common in newer homes but still found in older Marlborough properties. When the door closes, the springs extend. When it opens, they contract.
Extension springs wear out at roughly the same rate as torsion springs, but they fail differently. They're also lighter duty, which is why they're typically found on lighter doors or older installations. If one extension spring breaks, the other side still has some tension, which can cause uneven door movement.
Safety cables run through extension springs to catch them if they snap. Without those cables, a broken extension spring becomes a serious hazard.
Look above your door from inside the garage. Do you see a single horizontal spring wound around a shaft? That's torsion. Do you see two springs running parallel along the sides of the frame? Those are extension springs.
Still unsure? A quick photo sent to our team here at Garage Door Marlborough can confirm which type you're working with. This matters when you're getting an estimate for replacement.

Torsion springs typically cost more to replace than extension springs, partly because they require precise calibration. A technician needs to wind them to the correct tension, which involves special equipment and expertise. Extension spring replacement is often cheaper but still requires professional installation.
Labor costs vary, but expect to pay between $200 and $400 for either type in the Marlborough area, plus the spring itself. A torsion spring runs $75 to $150, while extension springs are usually $50 to $100 per pair. Never attempt to replace garage door springs yourself. The tension stored in these springs can cause serious injury.
We've written extensively about snapped garage door springs in Marlborough and what to do right now if yours breaks unexpectedly. That post covers emergency steps and when to call for help.
Your spring type influences how your opener works, how smoothly your door operates, and what safety features you need. If you're considering a new opener or upgrading your system, the spring type matters. A mismatch between spring and opener can lead to premature wear or operational problems.
Springs are also affected by temperature swings. Marlborough winters are particularly hard on garage door springs, which is something we've documented in detail if you want to understand the seasonal angle better.
A single broken spring always needs replacement, not repair. Springs work as a system. If one fails, the other is already under stress and likely to fail soon after. We recommend replacing both springs at the same time, even if only one snapped.
If your door is slowing down, moving unevenly, or making unusual noises, your springs may be wearing out. These are signs to get a free inspection before a catastrophic failure occurs.
This is where precision matters. Every garage door has a specific spring requirement based on its weight, panel configuration, and insulation. Ordering the wrong spring wastes time and money.

How long do garage door springs last? Garage door springs typically last 7 to 9 years with normal residential use, equating to about 10,000 to 15,000 cycles. Frequency of use, climate conditions, and maintenance habits all affect lifespan.
Can I replace just one spring? No. If one spring fails, the other is under additional stress and will fail soon. Always replace both springs at the same time to ensure balanced, safe operation.
What does a broken spring sound like? A snapped torsion spring makes a loud bang or crack from above the door. You'll immediately notice the door becomes very heavy or won't open. Extension springs break more quietly but the door will feel unbalanced.
How much does spring replacement cost in Marlborough? Expect $275 to $550 total, including labor and parts. Torsion springs cost more than extension springs, both in materials and installation complexity.
Is it safe to operate my door with a broken spring? No. Do not use a garage door with a broken spring. The opener will strain, the door may fall unexpectedly, and you risk serious injury. Contact a professional immediately.
