If your garage door suddenly refuses to open. or drops faster than it should. there's a good chance a spring has failed. It's one of the most common service calls we get at Palm Harbor Garage Doors, and it happens more often here in Pinellas County than homeowners expect. Between the year-round humidity, the salt air drifting in off the Gulf, and summer temperatures that routinely push into the high 80s and low 90s, garage door springs here take a beating that springs in drier climates simply don't face.
<b>Torsion springs</b> and <b>extension springs</b> are both metal under constant tension. and metal and moisture don't mix. Palm Harbor averages around 51 inches of rain per year, and humidity regularly sits at 73% or higher throughout the summer months. That persistent moisture accelerates rust and corrosion in the coils, weakening the metal faster than normal wear would on its own.
If you live in neighborhoods closer to the water. like Crystal Cove Estates or the areas near Ozona along the Dunedin Causeway. salt-laden air adds another layer of stress on the metal. Even homes further inland in East Lake or the Curlew Road corridor aren't immune. The humidity alone is enough to shorten a spring's lifespan noticeably compared to the national average.
For more on how Palm Harbor's environment specifically affects garage door hardware, check out our post on why garage door springs fail faster in Palm Harbor.
Springs rarely fail without warning. Here's what to watch for:
- The door feels unusually heavy. Try disconnecting the opener and lifting the door manually. It should float up with minimal effort. If it feels like you're lifting dead weight, the spring tension is gone. - The door won't open at all. A snapped torsion spring often means the opener motor can't lift the door on its own. you'll hear it straining, or the door barely moves. - Visible gap in the coil. Look at the spring mounted above the door. A torsion spring that's broken will have an obvious gap in the coil. - Loud bang from the garage. A breaking spring releases stored energy suddenly. many homeowners describe it as sounding like a gunshot or a car backfire inside the garage. - Uneven movement. If one side of the door rises faster than the other, an extension spring on one side may have weakened or snapped.
If you're also noticing issues with the opener straining or running but not moving the door, take a look at our opener troubleshooting guide. sometimes what looks like an opener problem is actually a spring issue.
Most homes in Palm Harbor built in the last 20 years use torsion springs. the heavy coil mounted horizontally above the door opening. They're generally safer and last longer: typically 7,15 years or 10,000,20,000 cycles depending on quality.
Extension springs run along the horizontal tracks on either side of the door. They're common on older homes and lighter doors. They're less expensive upfront but have shorter lifespans. usually 4,10 years. and when they snap, they can fly with serious force if safety cables aren't in place.
If your home has extension springs without safety cables, that's worth addressing when you replace them.
For most single-car residential doors in the Palm Harbor area, expect to pay $150,$350 for a torsion spring replacement including parts and labor. Extension spring replacement tends to run a bit less: roughly $120,$200.
A few things affect the final number:
- Single vs. double door. larger, heavier doors require bigger springs, which cost more - Both springs replaced at once. always the right call. Springs are installed in pairs and wear at the same rate. Replacing both when one fails saves you a second service call (and second labor charge) in the near future - Emergency or after-hours service. weekend and evening calls typically carry a premium - Spring quality. standard-cycle springs cost less upfront; high-cycle springs (rated for 25,000+ cycles) cost more but make sense for busy households or attached garages used multiple times a day
If additional damage is found. worn cables, a bent track, or a struggling opener. that will add to the total. A good technician will point these out during the repair, not after.
We're not going to pretend the internet doesn't have tutorials for this. It does. But garage door springs are under extreme tension. enough to cause serious injury or death if the winding process goes wrong. This isn't like swapping a light fixture. The tools required are specific, the technique matters, and one slip can send a metal coil flying at high speed.
Plus, an improperly installed spring puts uneven stress on the door, the opener motor, and the cables. which typically leads to more expensive damage down the road. Professional replacement takes less than two hours and comes with the confidence that the job was done right.

A few simple habits go a long way in this climate:
1. Lubricate the springs twice a year with a silicone-based spray or white lithium grease. Avoid standard WD-40. it can actually dry out the coils. Do this in spring and fall, especially before the summer rainy season hits. 2. Keep the coils clean and dry. If your garage doesn't seal well at the bottom or sides, moisture accumulates quickly. A good door seal helps. 3. Schedule a yearly inspection. A technician can catch early signs of rust or tension loss before you're stranded with a door that won't open on a Monday morning.

Q: Can I open my garage door if a spring is broken? A: Technically, yes. you can disconnect the opener and lift manually. but a door with a broken spring is extremely heavy and off-balance. You risk injuring yourself or damaging the opener. It's best to leave it down and call for service.
Q: Should I replace both springs even if only one broke? A: Yes. Both springs were installed at the same time and have the same number of cycles on them. If one failed, the other is likely close behind. Replacing both during the same visit saves you a second service call and keeps the door balanced.
Q: How long does spring replacement take? A: For most standard residential doors, a professional can complete the job in 60,90 minutes. If cables or other hardware need attention at the same time, add a little more time. but it's rarely an all-day job.
