5 Warning Signs Your Garage Door Springs Are About to Fail in Dundee
2026-04-17 6 min read
Garage door springs are the hardest-working component on your door, and they're the ones most homeowners never think about until something goes wrong. In Dundee, the combination of daily use, Florida's relentless humidity, and the occasional cold snap. temperatures have dipped into the upper 20s here in recent years. puts springs under stress that shortens their lifespan faster than the industry averages suggest. A standard torsion spring is rated for about 10,000 cycles. If you open and close your garage door four times a day, that's roughly seven years of life under ideal conditions. In Polk County's climate, you may get less.
The good news is that springs rarely fail without giving you some advance warning. Here are the five signs that your garage door springs are headed toward failure. and what to do about each one.
1. The Door Feels Unusually Heavy When You Lift It Manually
Try this test: disconnect your opener by pulling the emergency release cord (a red rope hanging from the rail) and lift the door by hand. A properly balanced door with functioning springs should rise smoothly with one hand and stay in place when you let go at mid-height. If it feels heavy, drops back down, or requires real effort to raise, the springs are losing tension and are no longer counterbalancing the door's weight correctly.
This is a critical sign. A door in this condition is putting enormous extra strain on your opener motor every single cycle. Most standard garage doors weigh between 150 and 250 pounds. without properly functioning springs, your opener is attempting to lift most of that weight on its own, which burns out the motor significantly faster.
2. You Hear a Loud Bang From the Garage
This one is unmistakable. When a torsion spring snaps, it releases all of its stored tension at once. and it sounds like a gunshot or a car backfiring inside your garage. If you hear a loud bang and then your door won't open, that's almost certainly a broken spring. The door may still move a few inches but will feel extremely heavy and resist opening.
Do not attempt to force the door open manually if you suspect a broken spring. The sudden release of tension and the imbalanced weight can cause the door to drop unexpectedly. This is a situation that calls for a professional. and for Dundee homeowners, it's worth knowing in advance who you'll call. You can save time by bookmarking our contact page before you ever need it.
3. Visible Gaps or Separation in the Spring Coil
Look up at the spring or springs above your garage door (they run horizontally along a bar above the door on most residential systems). A healthy torsion spring is a continuous, tightly wound coil. If you see a visible gap or separation anywhere in that coil. even just half an inch. the spring has already broken or is in the process of failing. Don't wait on this one.
Extension springs, used on some older homes in Dundee's central neighborhoods, run along the horizontal tracks on either side of the door. These can be more difficult to inspect visually, but look for sections that appear stretched out, uneven, or show rust and corrosion along the coils.

4. The Door Opens Crooked or One Side Moves Faster Than the Other
If your garage door rises unevenly. one side pulling ahead of the other, or the door visibly tilting as it travels. that's a sign that one spring has weakened or failed while the other still has tension. This is especially common on doors with two extension springs (one on each side). When one fails, the intact spring continues pulling its side up while the failed side drags.
Running your door in this condition is hard on everything. the cables, the rollers, the tracks, and the opener. In a worst case, a door running severely off-balance can jump its track entirely, which turns a spring replacement into a much larger repair job. If your door in the Mabel Loop Ridge subdivision or anywhere along SR 17 through Dundee is rising crooked, stop using the opener and call for service.
5. Rust and Corrosion on the Coils
This is the slow-burn warning sign that's easiest to miss. In Dundee's high-humidity environment. where summer humidity regularly averages 76% or higher. steel springs are under constant moisture pressure. Rust weakens the metal at a microscopic level long before any visible crack appears. Coils that look orange or brown, especially near the ends where the spring hooks to the center cone or anchor bracket, are at elevated risk of sudden failure.
Lubrication is the best preventive measure. A silicone or lithium-based spray applied to the spring coils twice a year displaces moisture and significantly slows rust formation. This is something any homeowner can do in about five minutes. For a complete seasonal maintenance approach, our guide to preparing your garage door for weather changes covers lubrication timing and what else to inspect while you're at it.
DIY vs. Professional Spring Replacement
Let's be direct: garage door spring replacement is not a DIY job for most homeowners. Torsion springs are wound under hundreds of pounds of torque. Releasing or winding them incorrectly can cause the spring to snap, the winding bar to slip, or the door to fall. any of which can cause serious injury. This is one of the most common causes of garage door-related injuries reported nationally.
Professional spring replacement in the Dundee area typically runs $150,$350 depending on the spring type, size, and whether both springs need replacement (which is recommended even if only one has failed. the other is usually close behind). If you're also dealing with cable damage as a result of the spring failure, our complete cable repair guide explains what that repair involves and what to expect cost-wise.
Dundee Garage Doors serves homeowners throughout Polk County. from Dundee and Winter Haven to Bartow and Lake Wales. and spring replacement is one of the most common calls we receive. Getting it handled before the spring actually snaps is always faster, cheaper, and safer than dealing with an emergency on a busy morning when you can't get your car out.

Frequently Asked Questions
Q: How do I know if I have torsion springs or extension springs? A: Torsion springs are mounted horizontally on a metal bar directly above the garage door opening. Extension springs run along the horizontal tracks on each side of the door. Torsion springs are more common in newer installations and are generally considered safer. If your home was built before the 1990s, there's a good chance it has extension springs.
Q: Should I replace both springs even if only one broke? A: Yes, and most professionals will strongly recommend it. Both springs are typically the same age and have endured the same number of cycles. If one has failed, the other is usually close behind. Replacing both at the same time saves you a second service call. and more importantly, prevents an unexpected failure of the second spring at an inconvenient time.
Q: Can I still use my garage door if I think a spring is weakening but hasn't broken yet? A: Use caution. If the door feels heavy, moves unevenly, or shows visible rust and coil gaps, it's best to limit use and schedule an inspection promptly. Continuing to run a door with a failing spring puts stress on your opener motor, cables, and hardware. and increases the risk of a sudden failure that could damage property or cause injury.
