If you walked into your garage one morning and heard a loud bang — or tried to open your door and it wouldn't budge — there's a good chance you've got a broken spring. It's one of the most common garage door failures there is, and in Foster, it tends to happen more often in the colder months when metal contracts and stress builds up after repeated freeze-thaw cycles.
The good news: a broken spring doesn't mean you need a new door. The not-so-good news: it's one of those repairs you really do need a professional for. Here's a straight-talk guide to what's happening, what to watch for, and what to expect.
Your garage door is heavy — a standard single-car door weighs 130–150 pounds, and a two-car insulated steel door can push well over 300 pounds. The springs are what actually lift that weight. Your opener just guides the movement; the springs provide the counterbalance force that makes the whole system work. Without a functioning spring, even a powerful opener can't safely move the door.
There are two types you'll encounter on Foster homes:
Torsion springs run horizontally above the door opening, mounted on a metal shaft. They wind and unwind as the door moves and provide smooth, balanced lifting. Most newer homes and garage upgrades from the past two decades use torsion springs.
Extension springs run along the sides of the door tracks and stretch and contract as the door opens and closes. They're more common on older doors — and a lot of Foster's housing stock, which includes homes built in the 1970s and 1980s, still has extension spring systems. These doors often also have safety cables threaded through the springs, which is important — if the spring snaps and there's no cable, it can fly across the garage at high speed.
Springs don't always snap without warning. Here are things to watch for:
- The door feels unusually heavy when lifted manually. A properly balanced door should feel like about 10–15 pounds in your hands. If it feels like you're lifting the door itself, the spring is losing tension. - The door doesn't stay open halfway. Lift the door to about waist height and let go. It should hold its position. If it drifts back down, spring tension is off. - Visible gaps in the torsion spring coils. Healthy coils touch each other. If you see a gap of an inch or more in the spring, that spring is near the end of its life. - Loud grinding or squeaking during operation. Rust and lack of lubrication accelerate spring wear — and up here in Foster's damp, wooded environment, rust is a real factor. - The opener strains, slows, or stops midway through a cycle. The opener is working too hard to compensate for a weakening spring.
If the spring has already snapped, you'll know — there's typically a loud bang (often mistaken for something else in the house), and the door simply won't open. Stop using the door immediately. Our services page covers emergency response for exactly this situation.
We'll be direct about this: garage door spring replacement is one of the few home repairs where attempting it yourself can genuinely put you in the hospital. Torsion springs store enormous mechanical energy — enough to lift hundreds of pounds thousands of times. When that energy releases unexpectedly, the results can be severe. Professional technicians use calibrated winding bars and specific safety equipment for exactly this reason, and the small cost savings from a DIY attempt simply don't justify the risk.
Beyond safety, there's the practical issue that every garage door is unique. The spring has to be matched precisely to the door's weight and size. Using the wrong spring — or setting the wrong tension — leads to premature failure, uneven wear, and added strain on your opener motor.
This is also why those online tutorial videos are a problem. What works for the door in the video may not work for your door. Neighbors in Glocester have learned this the hard way.
Look above the closed door. If you see a single horizontal spring (or two springs) mounted on a shaft centered above the opening, you have a torsion system. If you see springs stretched along the horizontal tracks on each side of the door, you have an extension system.
For older Foster homes with extension springs, this is often a good time to consider upgrading to a torsion system during the replacement. Torsion springs last longer, provide more balanced lifting, and are generally safer. It costs more upfront, but it's worth the conversation.
Expect to pay in the range of $350–$750 for a single spring replacement, or $500–$1,500 for a pair, depending on spring type, door size, and what's included in the service. A reputable technician will also inspect your cables, check the door's balance, lubricate all moving parts, and test the full system — not just swap the spring and leave.
Be cautious of very low quotes. Budget jobs often cover only the spring itself, with no inspection, cable check, or balancing. That approach tends to cost more in the long run. When evaluating quotes, ask specifically what's included beyond the spring itself.
Spring quality also matters significantly. Budget springs are often rated for 5,000–10,000 cycles and may fail within five to seven years. Higher-quality springs from established manufacturers are rated for 25,000–50,000+ cycles and can last 15–20 years — a much better value over time, especially for a household that uses the garage multiple times a day.
For context on the broader decision of whether to repair or replace, our post on making the repair-or-replace call in Foster covers that in more detail.
Once you've had springs replaced, a little maintenance goes a long way. Lubricate the springs with a garage door-specific lubricant (not WD-40, which dries out and attracts dirt) two or three times a year — especially before winter sets in. Foster's climate, with cold winters and high annual precipitation, accelerates rust and metal fatigue. Regular lubrication is the single biggest thing you can do to extend spring life.
If you're not sure your current springs are in good shape and want a professional eye on the full system, contact Garage Door Foster to schedule an inspection. We'll tell you honestly what's wearing out and what still has life in it — no upselling, no pressure.
How long do garage door springs typically last in Foster's climate? Most standard springs are rated for 10,000 cycles — about 7 to 10 years for an average household. In Foster's climate, where freeze-thaw cycles and humidity accelerate metal fatigue, springs on the lower end of the quality spectrum may fail earlier. High-cycle springs rated for 25,000+ cycles are a worthwhile investment for most Foster homeowners.
Can I still use my garage door if a spring is broken? No — and this is important. Operating the door with a broken spring puts enormous stress on the opener motor and cables, and risks a complete door failure. The door could drop suddenly, potentially injuring someone or damaging a vehicle. Stop using the door and call for service. Check our FAQ page for what to do while you wait.
Do I need to replace both springs at the same time? If you have a two-spring system and one breaks, replacing both at the same time is strongly recommended. The surviving spring has the same amount of wear as the one that failed. Replacing only the broken spring almost always means you'll be calling for service again within months when the second one goes. It's more cost-effective to do both in one visit.
