If you walked into your garage this morning and the door wouldn't budge. or you heard a loud bang like a gunshot from the garage. there's a good chance a spring just gave out. It's one of the most common calls we get from Brooksville homeowners, and it almost always happens at the worst possible time: early morning, right before work, or during one of our summer downpours.
Brooksville's climate plays a real role here. Hernando County sits in a humid subtropical zone where summers regularly push temperatures toward 90°F and the air stays thick with moisture from June through September. That relentless humidity accelerates corrosion on metal components, and garage door springs. which are under enormous tension 24/7. are especially vulnerable. If you've noticed your spring looking rusty or starting to gap, that's not cosmetic. It's a warning.
Most people don't think about their springs until one breaks. There are two main types you'll encounter in Brooksville homes:
Torsion springs sit mounted horizontally above the door opening. They twist (torque) to store energy and do the heavy lifting when the door opens. They're the standard on most newer sectional doors. including the concrete block homes you'll find throughout communities like Southern Hills and the Waterford development off Cortez Blvd.
Extension springs run along the side tracks and stretch to provide lifting force. They're common on older homes and lighter doors. They cost less up front, but they're also the more dangerous type if they snap. a broken extension spring can fly across the garage with real force.
Both types are rated by cycle life. typically 10,000 cycles for standard springs, which translates to roughly 7,10 years of average use. High-cycle springs rated for 25,000+ cycles cost more but make sense if your garage is your primary entry point (most Brooksville families use the garage door far more than the front door).
Don't wait for a full break. These are the red flags to watch for:
- The door feels heavy when you try to lift it manually. springs do most of the weight-bearing work - Visible gaps or separation in the coils of a torsion spring - Rust or corrosion along the spring body, especially after our rainy season - The door opens unevenly or one side lags behind the other - A loud popping or snapping sound. that's usually the moment of failure - The opener strains or struggles, even on a door that's otherwise in good shape
If you're already dealing with a door that won't open properly, our post on repair versus replacement decisions for Brooksville homeowners can help you figure out whether the spring is the whole story. or a symptom of bigger issues.
For homeowners in Brooksville and nearby Spring Hill, here's what to realistically expect:
- Extension spring replacement: $120,$200 per spring, including labor - Torsion spring replacement: $150,$350 per spring, including labor - Full job (both springs on a single door): $250,$500 in most cases
In Florida, spring replacement typically runs toward the mid-range of national pricing. You'll pay closer to the top of that range if you need same-day service, if the door is larger than standard, or if additional hardware like cables or drums needs attention at the same time.
One important note: always replace both springs at once, even if only one has broken. The springs on a two-spring system wear at the same rate. If one fails, the other is likely weeks or months behind it. Replacing both during the same service visit saves you a second trip charge and keeps the door balanced.
You can see the full list of what's covered in a typical service call on our garage door services page.
This isn't false modesty on our part. it's physics. Torsion springs are wound under hundreds of pounds of tension. A mistake during installation or removal can send a spring flying with enough force to cause serious injury. Professional technicians use specialized winding bars and follow precise torque calculations based on your door's exact weight and height.
Extension springs are somewhat more accessible, but they carry their own risk. Without properly installed safety cables threading through the coil, a broken extension spring becomes a projectile.
The $50,$100 you might save attempting this yourself is not worth it. Call a pro. This is one of those situations where the danger is real and immediate, not theoretical.
Brooksville's humidity is harder on springs than the marketing materials typically acknowledge. A few practical steps will help maximize spring life after replacement:
- Lubricate springs twice a year with a garage-door-specific lubricant (not WD-40, which can strip existing coatings) - Keep the garage ventilated. our summer heat and humidity accelerate rust when air stagnates - Inspect visually each season. a few seconds of looking can catch early corrosion before it becomes a failure
If you have questions about what else might be wearing down while a technician is already out, check our FAQ page for a rundown of what a standard inspection covers.
Q: My spring broke and the door is stuck shut. Can I force it open manually? A: You can attempt to open it manually using the emergency release cord on the opener, but a garage door without a functional spring is extremely heavy. often 150,200 pounds for a standard double door. Don't try to hold it open by yourself, and never go under a door that isn't fully supported. Call for same-day service instead.
Q: How do I know if I have torsion or extension springs? A: Look above the door when it's closed. If you see a single horizontal spring (or two springs) mounted on a metal bar running across the top of the door opening, those are torsion springs. If you see springs running along the horizontal tracks on either side of the door, those are extension springs.
Q: Is it worth upgrading to high-cycle springs? A: In Brooksville, yes. especially if your garage is your primary entry point. Given our humidity, higher-quality galvanized springs resist corrosion better and last significantly longer. The upcharge is modest and often worth it over the life of the door.
