If you've ever heard a loud bang come from your garage. like a firecracker going off. there's a good chance a garage door spring just snapped. It's one of the most common service calls we get at Garage Door Groveland, and it almost always catches homeowners off guard. The good news is that spring problems usually give you warning signs well before they fail completely. The bad news is that most people don't know what to look for.
Living in Groveland means dealing with a subtropical climate that's tough on metal components. Summers here push into the low-to-mid 90s with humidity that lingers morning through evening. and that combination quietly accelerates wear on springs, cables, and hardware year after year.
Your garage door is heavy. most single doors weigh 130,200 lbs, and double doors can exceed 300 lbs. Springs are what make it feel light. They store mechanical energy when the door closes and release it when the door opens, counterbalancing the weight so your opener (or your arm) doesn't have to do all the heavy lifting.
There are two main types:
- Torsion springs. mounted horizontally above the door opening. Most common in newer homes and generally safer when they fail. - Extension springs. run along the horizontal tracks on each side. Older and more common in homes built before the 2000s.
In communities like Trilogy Orlando and Eagle Pointe here in Groveland. where a lot of the housing stock is relatively new construction. torsion springs are the norm. But if you're in one of the older homes near downtown Groveland or a farmhouse-style property on the outskirts toward Clermont, extension springs are more likely what you've got.
Springs are typically rated for 10,000 cycles. one cycle being the door opening and closing once. If you use your garage door four times a day, that's roughly 7 years of life under ideal conditions. But Groveland's climate is anything but ideal for metal components.
High humidity causes surface rust to form on spring coils, and that rust weakens the metal over time, making springs more prone to sudden failure. Heat cycling. the expansion and contraction metal goes through as temperatures swing from a cool morning to a scorching afternoon. adds cumulative stress to each coil. If your springs haven't been lubricated regularly, that wear compounds even faster.
The result: springs in Florida homes often fail closer to the 7,9 year mark, sometimes sooner with heavy use or neglected maintenance.

Don't wait for the loud snap. Here's what to watch for:
- The door feels unusually heavy when you lift it manually. If a spring is weakening or broken, the opener and your arms carry the full door weight. - The door won't open more than a few inches, then stops or reverses. - You hear grinding, squeaking, or creaking that wasn't there before. early signs of corrosion or inadequate lubrication. - Visible gaps in the spring coils. a broken torsion spring often has a clear separation you can see from the floor. - The door closes too fast or slams down rather than lowering smoothly. - Cables look frayed or loose. springs and cables work together, and a failing spring puts extra load on cables.
If you're seeing multiple items on this list, don't keep operating the door. A broken spring can damage your opener motor, bend tracks, and in worst cases cause the door to fall unexpectedly.
Let's be honest here: garage door spring replacement is one of the few home repairs we'd strongly advise against doing yourself. Torsion springs are under extreme tension. enough that a mistake during winding or unwinding can cause serious injury. This isn't like changing an outlet or patching drywall.
Professional replacement typically takes 1,2 hours for a torsion spring setup. A trained tech has the right winding bars, knows the exact tension specs for your door's weight, and can inspect cables, drums, and the opener at the same time. You can check out our full list of garage door services to understand what a professional inspection covers.
Yes. almost always. If one spring has failed, the other is likely close to the same point in its life cycle. Replacing both ensures balanced tension and prevents a second service call a few months down the road. It also protects your opener from working against uneven load.
When replacing springs in a Florida climate, ask about higher-cycle springs. springs rated for 20,000 or 30,000 cycles rather than the standard 10,000. The cost difference is modest, but the extended lifespan is significant, especially given the wear our local humidity adds to standard springs.
If you hear that loud crack and your door stops working:
1. Do not try to force the door open. manually or with the opener. 2. If your car is inside, call for service rather than attempting to lift the door yourself. 3. Disconnect the opener (pull the red cord) only if you need to open the door with help from another person, and only lift if both springs are intact. otherwise leave it closed. 4. Contact a technician as soon as possible. Spring replacement is typically a same-day repair.

How long do garage door springs last in Groveland's climate? Standard springs are rated for around 10,000 cycles, which works out to roughly 7,10 years under normal use. However, Groveland's heat and humidity can shorten that timeline, especially without regular lubrication. Upgrading to higher-cycle springs at replacement time is worth considering.
Can I still use my garage door opener if a spring is broken? Technically the opener may still run, but you shouldn't use it. Without functioning springs, the opener has to lift the full weight of the door, which can burn out the motor and cause further damage. Leave the door in the closed position and call for service.
Why do both springs need to be replaced at the same time? If one spring has broken after years of use, the other has endured the same wear and is likely close to failing too. Replacing only one leaves you with uneven tension, which strains the opener, cables, and the door itself. and means another service call sooner rather than later.
