If your garage door suddenly stopped working or made a loud bang when you tried to open it this morning, there's a good chance a spring just let go. It's one of the most common service calls we get at Pompano Beach Garage Doors. and it's also one of the most mishandled by homeowners who try to fix it themselves. Here's what you actually need to know.
Standard residential garage door springs are rated for somewhere between 10,000 and 20,000 open/close cycles. In a typical household, that translates to roughly 7 to 15 years of service. But in Pompano Beach. and honestly, across all of coastal Broward County. those numbers are optimistic.
The problem is the environment. Pompano Beach sits directly on the Atlantic, and the salt air that makes neighborhoods like Garden Isles and Santa Barbara Shores such great places to live is genuinely aggressive toward metal. Salt accelerates oxidation, promotes rust formation on spring coils, and causes surface corrosion that weakens the metal from the outside in. What appears as surface rust is actually structural deterioration happening at the coil level.
Humidity compounds the issue. When warm, moist Atlantic air contacts cooler metal at night, condensation forms in the tight gaps between spring coils. That trapped moisture accelerates rust and creates stress points where metal fatigue develops over time. On top of that, wind events. even smaller tropical systems that pass through without making headlines. put lateral pressure on garage door panels that transfers stress through the cable and spring system with every storm.
The practical result: springs that might last a decade in Coral Springs or an inland suburb of Fort Lauderdale can show serious wear and fail in half that time in a coastal zip code without proper maintenance.
Springs don't always announce failure with a bang. Sometimes they degrade quietly. Here are the signs to watch for:
- The door feels unusually heavy when you disconnect the opener and try to lift it manually. A properly balanced door should lift with minimal effort. If it feels like you're lifting dead weight, your spring tension is compromised. - The door opens unevenly. one side rises faster than the other, causing the door to look crooked during operation. - Visible rust or gaps in the coil. look at the spring above your door. If you see surface rust, pitting, or a visible gap in the coil, the spring is either failing or already broken. - A loud bang when you operated the door. Torsion springs (the horizontal spring mounted above your door) make a sharp, startling sound when they snap. If you heard it, stop using the door immediately. - The opener strains or reverses. if your opener is suddenly struggling to lift the door or reversing before it fully opens, the spring may have lost tension, leaving the motor to do all the work.
If your opener is acting up, it's worth reading our guide to garage door opener problems in Pompano Beach. sometimes the issue is the spring, not the opener itself.
Most modern sectional garage doors use torsion springs. a single spring (or two, on heavier doors) mounted on a metal shaft directly above the door opening. They twist to store energy and release it to help lift the door. Torsion springs are stronger, more durable, and generally considered safer than the alternative.
Extension springs are mounted on either side of the door along the horizontal track and stretch as the door closes. They're more common on older doors and lighter single-car setups. They tend to cost less to replace, but they also have more exposure to air, which is a real concern in a salt-air environment like ours.
In a coastal market, if your door currently has extension springs, it's worth asking your technician whether upgrading to torsion springs makes sense at replacement time. The longer service life and better corrosion resistance can make a meaningful difference here.
Here's what you can realistically expect to pay:
- Extension spring replacement: Roughly $150,$250 per spring, parts and labor included - Torsion spring replacement: Roughly $200,$350 per spring, parts and labor included - Replacing both springs (recommended): $300,$500 for most single-car doors
For Broward County homeowners, costs are in line with the South Florida market, which runs slightly higher than statewide averages due to labor rates and the higher demand for corrosion-resistant components. Always get the full cost including labor. spring parts alone are cheap, but professional installation is where the real value is.
One important note on costs: always replace both springs at the same time, even if only one has broken. Springs on the same door experience the same wear and the same salt-air exposure. If one fails, the other is not far behind. Replacing both during a single service call saves you a second trip charge and prevents the second failure. which almost always happens at the worst possible moment.
We hear from homeowners who want to replace springs themselves to save money. It's understandable, but we'd strongly advise against it. Garage door springs are under enormous tension. hundreds of pounds of stored mechanical force. A torsion spring that releases unexpectedly during installation can cause severe injury. Professional technicians have the specialized winding bars, safety training, and experience to handle this safely.
Beyond safety, there's the sizing issue. Springs are matched to the specific weight and height of your door. An incorrectly sized spring doesn't just fail faster. it can damage your opener, bend your tracks, and create an unbalanced door that's dangerous to operate.

You can't stop salt air from existing, but you can slow its effects:
1. Lubricate your springs every 3,4 months using a silicone-based or white lithium grease spray. This creates a moisture barrier and reduces friction. Avoid WD-40. it's a solvent, not a lubricant, and it dries out quickly. 2. Schedule an annual inspection. A technician can identify corrosion, coil separation, or tension loss early. before you're stranded with a door that won't open. 3. Ask about galvanized or powder-coated springs when it's time to replace. These offer better corrosion resistance and are worth the modest price premium in our environment. 4. Keep the garage area clean after storms, rinsing off any visible salt residue from hardware, tracks, and the spring area.
If your door is also showing signs of panel wear or rust along the bottom sections, take a look at our panel repair guide to understand whether you're looking at a repair or a full replacement situation.

In a coastal environment like Pompano Beach, where salt air and humidity accelerate metal corrosion, expect springs to last 5,8 years with average use and basic maintenance. Springs on doors that get heavy daily use (4+ cycles per day) or that haven't been lubricated regularly may need replacement sooner. Inland cities like Coral Springs typically see longer spring life for comparison.
No. You should stop using the door immediately. Without spring tension, the full weight of the door falls on the opener motor and cables. Operating the door in this condition can burn out your opener, fray or snap the cables, and create a dangerous situation where the door drops unexpectedly. Disconnect the opener and call for service.
Look at your garage door from the inside with the door closed. If you see a single long spring mounted horizontally on a metal bar directly above the door, that's a torsion spring setup. If you see springs running along the horizontal tracks on either side of the door (stretching toward the back of the garage), those are extension springs. Not sure?
