Springs do the lifting, not your opener
Most people assume the garage door opener lifts the door. It doesn't. The opener guides the door up and down, but the real work is done by the springs, which counterbalance the door's weight so that a 200-pound door feels like it weighs about ten. When a spring breaks, that counterbalance is gone, and the full weight of the door lands on the opener, the cables and your back if you try to lift it.
That's why a broken spring stops everything. It's also why we treat spring repair as both the most common and the most safety-critical job we do in New Berlin. Our technicians replace springs with the correct size for your door, set the right tension, and balance the door so it runs smoothly and safely for years.
Signs your garage door spring is broken
- A sudden, very loud bang from the garage, often when nobody is using the door
- A visible two-inch gap in the coils of the torsion spring above the door
- The door opens only a few inches and stops, or the opener hums and strains
- The door feels extremely heavy if you disconnect the opener and try to lift it
- The door rises crooked or slams down quickly when closing
- An extension spring is visibly stretched, gapped or hanging on its safety cable
If you suspect a broken spring: stop using the door. Don't try to lift it by hand, and don't pull the emergency release if the door is open. Keep the car inside or outside until we arrive, unplug the opener and call (262) 555-0172.
Torsion springs vs. extension springs
There are two spring systems on residential garage doors, and we repair both. Which one you have affects the parts, the process and your options.
| Torsion springs | Extension springs | |
|---|---|---|
| Where they are | On a steel shaft directly above the door | Along each horizontal track, parallel to the ceiling |
| How they work | Twist as the door closes, unwind to lift it | Stretch as the door closes, contract to lift it |
| Smoothness | Very smooth and even | Can be jerkier as they age |
| Typical lifespan | Longer; high-cycle options available | Generally shorter |
| Safety | Contained on the shaft | Need safety cables to contain them if they break |
| Common on | Most newer and heavier doors | Many older, lighter single doors |
Many of the older ranch homes in New Berlin still have extension springs. If yours are worn out, we can replace them like for like, add safety cables if they're missing, or convert the door to a torsion system for smoother, quieter operation.
How we replace garage door springs
- Secure the door. We clamp the door in place so it can't move while we work.
- Measure and weigh. We identify wire size, inside diameter and length of your springs, and check the door's actual weight and height, because the springs on your door aren't always the right ones for it.
- Release tension safely. Using proper winding bars, never screwdrivers, we unwind the remaining spring under control.
- Inspect related parts. We check cables, drums, center and end bearings and the shaft. Worn cables or bearings are best replaced now while the system is unloaded.
- Install and wind. New springs are installed and wound to the correct number of turns for your door.
- Balance and test. We fine-tune tension so the door holds at mid-height, lubricate, adjust the opener and test the safety reverse.
Why the right spring size matters
Springs aren't one-size-fits-all. A spring that is too weak leaves the door heavy, making the opener work harder and wear out sooner. A spring that is too strong makes the door fly up and drift open, and it puts extra stress on cables and drums. Previous owners and quick-fix services sometimes install whatever springs were handy, and we regularly find mismatched or incorrectly sized springs on New Berlin doors.
We calculate the correct spring for your door's weight, height and drum size. If the door has been upgraded, for example with added insulation or windows, its weight may have changed and the springs need to match.
Standard or high-cycle springs?
Standard springs are typically rated around 10,000 cycles. One cycle is the door opening and closing once. A household that uses the garage as its main entrance can easily hit four or five cycles a day, which means a standard spring might last seven years or less.
High-cycle springs use a larger wire and longer body to spread the load, and they are rated for 25,000 cycles or more. They cost more up front, but they can last two or three times as long, which often makes them cheaper over the life of the door. If you plan to stay in your home, or the garage door is your family's front door, we'll usually suggest them, and we'll show you both prices so you can decide.
Spring replacement and Wisconsin winters
Spring calls in New Berlin spike every winter, and it isn't a coincidence. Cold steel is slightly less forgiving, lubricant thickens, and the door often has extra weight from snow or ice frozen along the bottom. A spring that has been quietly fatiguing for years finally gives way on a frigid morning. Rust from humidity and road salt also creates weak points along the coils.
You can't stop springs from wearing, but you can avoid being surprised. A yearly inspection, ideally in the fall, lets us measure balance, look for gaps or rust and tell you if a spring is near the end of its life so you can replace it on your schedule instead of during an emergency.
Spring maintenance tips
- Lightly lubricate torsion springs two or three times a year with a garage-door lubricant to reduce friction and rust.
- Once a season, disconnect the opener with the door closed and lift it halfway; a balanced door should stay put.
- Watch for rust, gaps in the coils or a door that has started to feel heavier.
- Never adjust torsion spring tension yourself; call a technician instead.
One spring or two?
Lighter single-car doors sometimes run on a single torsion spring. Most double doors and heavier insulated doors use two. When a single-spring door's spring breaks, it can make sense to convert to a two-spring setup: the load is shared, the door stays more balanced if one spring fails, and the springs typically last longer because each works less hard. We'll tell you whether your door is a good candidate when we replace the spring.
We'll also look at the bearings at each end of the torsion shaft and in the center bracket. Worn bearings make a grinding noise and put uneven stress on new springs, and they're simple to replace while the spring system is unloaded.
What a spring replacement visit costs
Spring replacement price depends on the spring type and size, whether one or two springs are needed, whether you choose standard or high-cycle springs, and whether cables or bearings also need replacing. Your technician will give you a written price for each option before starting, so you can choose between standard and high-cycle springs knowing exactly what each costs.
