Did your garage door suddenly become too heavy to lift, or did the opener groan and quit after raising it six inches?
Nine times out of ten, that's a broken spring. Springs are the single most common reason for garage door repair calls in Charlottesville, and they're also the part homeowners understand least. This guide explains how garage door springs work, why they break, and what to expect from a spring repair.
Springs Do the Heavy Lifting
A typical double garage door can weigh well over 100 pounds, and insulated or wood doors weigh more. Your opener isn't strong enough to lift that weight on its own. Springs counterbalance the door so it feels light. When a spring breaks, the full weight of the door is suddenly back, which is why it won't open.
Torsion Springs vs. Extension Springs
Torsion springs
Mounted on a bar above the door, torsion springs twist to store energy. As the door rises, they unwind and turn drums that wind up the lift cables. Torsion systems are smoother, more controlled, and the standard on most newer homes.
Extension springs
Found along the horizontal tracks on each side, extension springs stretch when the door closes and contract as it opens. They're common on older homes and lighter doors. Extension springs should always have a safety cable running through them. Without one, a broken spring can whip across the garage with dangerous force.
If your older Charlottesville home still has extension springs without safety cables, ask about adding them, or about converting to a torsion system.
Why Springs Break
- Cycle life. Springs are rated for a certain number of open-and-close cycles. Standard springs are commonly rated around 10,000 cycles. At several cycles a day, that's often under a decade of use.
- Rust. Humidity and moisture corrode the coils and increase friction.
- Cold weather. Metal becomes more brittle in the cold, so springs that are near the end of their life often snap on frosty mornings.
- Wrong size. Springs that don't match the door's weight wear out faster and strain the opener.
- Lack of maintenance. An unbalanced door and dry springs accelerate wear.
Signs a Spring Is Failing or Broken
- A loud bang from the garage, often when no one was using the door
- A visible gap in a torsion spring's coils
- The door opens only a few inches, then stops
- The door looks crooked or one side rises first
- Cables hanging loose from the drums
- The door slams shut or falls quickly when released
Why Spring Repair Isn't a DIY Job
Garage door springs store a great deal of energy. Winding or unwinding torsion springs requires proper winding bars and a precise procedure. Using the wrong tools, such as screwdrivers, or loosening the wrong set screw can release that energy instantly. Every year, people are seriously hurt attempting this repair. It's one of the clearest cases where calling a professional is the safe choice.
What a Professional Spring Repair Looks Like
- Measure the door and old springs to determine the correct wire size, length, and inside diameter.
- Safely unwind and remove the old springs.
- Install new springs matched to the door's weight.
- Inspect cables, drums, and bearings, replacing anything worn.
- Wind and balance the door so it stays in place when lifted halfway.
- Test the opener's force settings and safety reversal.
Should You Replace Both Springs?
If your door has two torsion springs and one breaks, the other has been through the same number of cycles and is likely close behind. Replacing both at once usually saves a second service call and keeps the door balanced evenly.
Consider High-Cycle Springs
If your family uses the garage as the main entrance, high-cycle springs rated for many more cycles than standard ones can be worth the modest upgrade. They cost more up front but can last years longer.
Cables and Drums: The Spring's Partners
Springs don't work alone. Lift cables run from the bottom corners of the door up to drums on the torsion bar. When a spring breaks, the sudden change in tension can cause a cable to slip off its drum or fray. That's why a good spring repair always includes an inspection of the cables, drums, and center bearing. Replacing a worn cable during the same visit costs far less than a separate trip later.
How Long Should New Springs Last?
Spring life depends on cycle rating and use. Count how many times your household opens and closes the door each day, then multiply by 365. Compare that with the spring's rated cycles to estimate its life. Families who use the garage as their main entry often run through standard springs faster than they expect, which is why high-cycle springs are popular.
Keep Springs Healthy Between Visits
- Lightly lubricate springs with a garage-door-specific product a couple of times a year
- Keep the door balanced with periodic professional tune-ups
- Don't let the opener compensate for an unbalanced door
A little care helps springs reach their full rated life and makes your next garage door repair in Charlottesville less likely to be an emergency.
