If you've ever heard a loud bang from your garage early on a January morning in Reading, there's a good chance you just lost a spring. It's one of the most common garage door failures we see here in Berks County. and it almost always happens at the worst possible time. Understanding what springs do, how to spot early warning signs, and why this is a job for a professional can save you money, frustration, and a potential trip to the ER.
Most homeowners don't think about springs until something goes wrong. But garage door springs are doing the heavy lifting every single time you open or close your door. Springs handle the counterbalance that makes a 200,400 pound door feel light. Without functioning springs, your opener motor is essentially trying to deadlift a small car. and it can't.
There are two main types you'll find on homes in Reading:
- Torsion springs mount horizontally above the door opening on a metal shaft. They twist to store energy and release it to lift the door. These are more common in modern installations, and they tend to be safer and longer-lasting. - Extension springs run along the horizontal tracks on both sides of the door, stretching to store energy. They're older technology, typically found on lighter doors or older homes. and Reading has plenty of older housing stock.
If you live in a neighborhood like Pendora Park, Centre Park, or an older Berks County row home community, there's a real chance your garage still has an extension spring setup that dates back decades.
Springs are rated by cycles, not years. One cycle equals one complete open-and-close. A standard spring is rated for around 10,000 cycles, which works out to roughly 7 to 10 years for a household that uses the door 2 to 4 times per day. Higher-cycle springs rated for 25,000 or more cycles last longer but cost more upfront.
Reading's climate adds an extra wrinkle. With winters that regularly dip to the mid-20s°F and springs that swing between cold nights and warm afternoons, the metal in your springs goes through constant thermal expansion and contraction. That stress accelerates wear. especially on older, lower-cycle springs. If you haven't replaced your springs in a decade and you're noticing any of the signs below, it's time to take a closer look.
Don't wait for the loud snap to take action. Here's what to watch for:
A balanced door should move up and down smoothly. If it looks crooked while moving, rises unevenly, or gets stuck partway, one spring may be weaker or broken. Continued use can damage tracks, rollers, cables, and your opener motor. This is the kind of issue covered in our guide to warning signs your door needs professional repair.
Garage door openers are not designed to lift the door's full weight. If your opener strains, makes unusual noises, or stops before the door is fully open or closed, failing springs are often the culprit. Left unchecked, this burns out the motor.
With torsion springs, a broken spring will have a visible gap. the coil separates when it snaps. If you see this, stop using the door immediately.
Cables work in tandem with springs. When a spring fails, cables can go slack or drape off their drums. This is a secondary sign that's easy to spot if you take a quick look at the sides of your door.
Reading's humid summers and wet winters create ideal conditions for corrosion. Rust weakens springs, shortens their lifespan, and makes catastrophic failure more likely. A little surface rust is a warning shot. significant rust is a call to action.
This is worth saying plainly: garage door spring replacement is not a DIY project. Torsion springs store enough energy to cause serious injury if they release unexpectedly during disassembly. Attempting to adjust, remove, or replace them without proper training and tools puts you at real risk.
Professionals use calibrated winding bars, torque specs for your specific door weight, and follow established safety procedures. The job typically takes 1,2 hours in experienced hands, and the result is a door that's balanced, safe, and not going to snap on you a month later because the tension wasn't set correctly.

If you hear the bang and your door won't open:
1. Don't force it. Using the opener to muscle through a broken spring will damage the motor. 2. Don't try to manually lift the door. You're lifting 150,400 pounds with no mechanical assistance. 3. Don't pull the emergency release if the door is open or partially open. the door could fall. 4. Call a professional. Most spring replacements can be done same-day. Reach out to schedule a repair and get someone out before the situation gets worse.
Also consider: when one spring fails, the other often isn't far behind. Many Reading homeowners opt to replace both at the same time to avoid a repeat call in a few months.
If your home is in an area like Spring Township or Wyomissing. where attached garages are standard and the door gets heavy daily use. upgrading to high-cycle springs (rated for 25,000,50,000 cycles) is worth the modest additional cost. You'll get more years out of them, and better-grade springs hold up better through Berks County's seasonal extremes. Ask about spring options when you call for a free estimate.
Costs vary based on the type of spring (torsion vs. extension), the number of springs, and the size and weight of your door. Most single-spring replacements are straightforward, but we recommend getting an in-person quote since older homes may have non-standard setups. Garage Door Company Reading offers free estimates. no surprises on the invoice.
No. Continuing to operate the door strains the opener motor and puts uneven stress on cables, rollers, and tracks. It also creates a safety hazard. a door with a broken spring can fall unexpectedly. Disconnect the opener and call for service.
Look above the door when it's closed. If you see a single long coil (or two coils) mounted horizontally on a metal rod above the opening, those are torsion springs. If you see springs running along the horizontal tracks on either side of the door, those are extension springs. Not sure? Send us a photo when you get in touch and we'll identify them for you.
