If there's one garage door repair call we get more than any other in Seminole, it's the broken spring. Most of the time, the homeowner had no idea anything was wrong until they heard a loud bang from the garage. or worse, found themselves trapped inside with a door that won't budge. The good news is that broken springs almost always give warning signs before they fail completely. The bad news is that most people don't know what to look for.
And in Seminole, the situation is a little more urgent than it would be further inland. Situated just a few miles from the Gulf Coast, our air carries constant salt and moisture. exactly the conditions that accelerate metal corrosion. If you're in a neighborhood like Thurston Groves or over near Boca Ciega Ridge, your garage door springs are working in a humid, salt-laced environment every single day, whether you realize it or not.
Your garage door likely weighs somewhere between 130 and 400 pounds depending on whether it's a single or double door and what it's made of. The springs do the heavy lifting. literally. They store mechanical energy when the door closes and release it when the door opens, counterbalancing the weight so your opener motor (and your arm, when you do it manually) isn't doing all the work.
There are two types you'll find on residential homes here:
- Torsion springs. mounted horizontally above the door on a metal shaft. These are the standard on most modern homes and handle the load more consistently over time. - Extension springs. mounted on either side of the door tracks, they stretch and contract with each cycle. You'll find these on older homes, and they tend to be more exposed to ambient conditions.
Most springs are rated for approximately 10,000 cycles. one cycle being one open and one close. For the average household using the garage door four to five times a day, that's roughly seven to ten years. But that's under normal conditions. In Seminole's coastal climate, the combination of salt air and high humidity puts constant corrosive pressure on spring steel, often advancing wear well ahead of what the cycle rating alone would suggest.
Don't wait for the loud bang. Here's what to watch for:
With the door fully closed, disconnect your opener (pull the red emergency cord) and try lifting the door manually. A properly balanced door should lift smoothly and stay in place at about waist height. If it feels extremely heavy or drops back down, your springs are likely weakened or already broken.
Look at the torsion spring above your door when it's in the down position. A broken torsion spring will have an obvious separation. a gap where the coil has snapped. The spring will also look slightly larger in diameter than normal because the tension has been released.
If your opener strains and the door barely lifts before stopping, that's a classic sign of a broken spring. The opener is hitting its resistance limit because it's trying to move the full weight of the door without spring assistance.
If your door rises unevenly. one side higher than the other. or shakes and stutters during operation, you may have a spring that's lost tension on one side. This also stresses your cables, rollers, and tracks, so the longer you wait, the more expensive the repair gets.
This one is specific to our area. Moisture trapped inside the coil gaps creates an environment where rust develops from the inside out. Regular lubrication can slow this process, but it cannot eliminate it entirely. If your springs look orange or crusty, have them inspected now. before they fail without warning.
Homeowners in drier inland climates might get 12 or 14 years out of a standard spring. In a Gulf Coast environment like Seminole. or nearby Indian Rocks Beach or Redington Beach. that lifespan can be considerably shorter without proactive maintenance. Salt is corrosive to steel, which is exactly what garage door springs are made from. A spring can appear intact while internal fractures are forming within the coil from repeated expansion, contraction, and corrosive exposure. These fractures develop silently until sudden failure. often with no advance warning at all.
This is why we always recommend having your spring system professionally inspected at least once a year. It's also worth knowing that if you've never had your springs serviced since moving in, there's a reasonable chance they're already showing internal wear even if they look fine from the outside. You can read more about how salt air and humidity affect your entire door system in our post on how Gulf-side conditions quietly damage your garage door.
Honest answer: replace both. If your door has two springs and one has broken, the other has been through the same number of cycles under the same corrosive conditions. Replacing only the broken one leaves you with mismatched tension. the newer spring carries more of the load, wears faster, and puts uneven stress on your cables and opener. You'll likely be calling for service again within a few months. It's smarter and cheaper in the long run to do both at the same time.
Garage door springs hold a tremendous amount of stored tension. enough to cause serious injury if released suddenly without the proper tools and technique. A standard torsion spring counterbalances a door weighing several hundred pounds. When one breaks, that energy releases violently. Professional technicians use specialized winding bars and follow strict safety protocols to safely release and reset spring tension. Attempting this without training and proper tools is genuinely dangerous. This is one of those jobs where the $50 you'd save on labor really isn't worth the risk.
If you suspect your springs are failing, stop using the door and contact our team for a same-day assessment. Seminole Garage Doors serves the entire Seminole area as well as neighboring Largo, Clearwater, and Pinellas Park.
Q: How do I know if my garage door spring is broken and not just the opener? A: Disconnect the opener by pulling the red emergency release cord, then try lifting the door by hand. If it's extremely heavy or won't stay up at waist height, it's the springs. If the door lifts smoothly manually but the opener still won't work, the problem is with the opener. You can also look for a visible gap or separation in the torsion spring above the door.
Q: How long does a garage door spring replacement take? A: Most spring replacements take between 45 minutes and 90 minutes for a professional. The technician will remove the broken spring, inspect the cables and hardware for secondary damage, install the new spring(s), and re-balance and test the door before leaving. Check our services page for what's included in a typical repair visit.
Q: Is it safe to use my garage door if I think a spring is broken? A: No. A garage door with a broken spring is unsafe to operate. Without the spring counterbalancing the door's weight, the opener motor is under extreme strain and the door can drop suddenly. Stop using the door and call a professional.
