How Garage Door Springs Work in Deadwood (And Why You Need Both Types)

2026-09-21 5 min read

Here's what most homeowners don't realize about garage door springs: your door doesn't work because of one spring type. Residential and commercial doors in Deadwood rely on either torsion or extension springs, and each one works differently. Understanding how they function helps you spot problems early and avoid a snapped spring that leaves you stranded.

How Torsion Springs Work

Torsion springs sit above your garage door, running along a metal shaft. When you open the door, these springs twist and unwind, storing mechanical energy that helps lift the heavy panel. The spring does roughly 90 percent of the lifting work. Your opener just assists.

This matters because torsion springs handle tremendous pressure. A single spring can support 200 to 400 pounds of force, depending on your door's weight. When a torsion spring breaks, the door becomes impossible to open manually. You'll feel the full weight pressing down.

Most residential doors use one or two torsion springs. Heavier doors, common in commercial settings, may need multiple springs working in tandem. Springs last 7 to 9 years with normal use, though factors like humidity and temperature swings in Deadwood affect lifespan. Check out our guide on when garage door springs need replacement for specific wear signs.

How Extension Springs Work

Extension springs run along the sides of your door frame, parallel to the horizontal tracks. Instead of twisting, they stretch and contract. As your door rises, these springs extend and store energy. As it lowers, they release that energy to guide the door down smoothly.

Extension springs are typically lighter duty than torsion systems. They work well for lighter residential doors. When one snaps, your door may still function partially, but it won't move evenly. You might notice the door tilting or binding on one side.

Safety cables run through extension springs as a backup. If a spring breaks, the cable catches the broken coil and prevents it from flying across your garage. This is a genuine safety feature, not optional.

Which Type Does Your Door Use?

Most single-car residential doors in Deadwood use torsion springs. Older homes sometimes have extension springs. Garage doors in Joseph or Enterprise area garages follow the same pattern. Commercial roll-up doors almost always use torsion systems because they need strength and durability.

You can identify which type yours has by looking above the door. Torsion springs sit on a horizontal shaft above the door opening. Extension springs hang on each side of the door frame near the tracks.

Why Spring Type Affects Repair Cost

The type of spring you need directly influences the cost of replacement. Torsion springs typically cost more than extension springs because they require precise balancing and professional installation. A snapped spring isn't a DIY fix. Improper installation can damage your door, opener, or worse, cause injury.

Extension spring replacement is sometimes simpler, but the safety cables still need proper attention. Both jobs require specialized tools and training. When you need an estimate on garage door spring repair cost, the spring type is one of the first factors we consider.

Maintenance Prevents Premature Failure

Springs fail faster when they're not properly lubricated. Rust and corrosion eat into the metal, weakening it over time. Deadwood's weather means humidity and temperature shifts stress your springs year-round.

Regular maintenance catches wear before a spring snaps. We recommend annual inspection and lubrication as part of routine garage door maintenance. Small investments now prevent emergency calls later.

What to Do If a Spring Breaks

If your spring snaps, stop using your door. Don't force it open or closed. A broken spring means your opener is working overtime, and you risk serious damage or injury.

Call us at (541) 906-3424 for same-day service. We handle spring replacement and can get your door working safely again quickly. Most spring jobs are straightforward when handled by professionals who understand the mechanics.

Your garage door springs are doing heavy work every single day. Respect that, maintain them, and replace them when they wear out. That's how you keep your door reliable and safe.

Frequently Asked Questions

How long do garage door springs last? Most garage door springs last 7 to 9 years with normal use (around 10,000 cycles). Humidity, temperature swings, and lack of lubrication shorten lifespan. Regular maintenance can help springs reach the upper end of that range.

Can I replace a garage door spring myself? No. Spring replacement requires specialized tools and knowledge of proper tension and balancing. Incorrect installation risks injury, door damage, and opener failure. Always hire a licensed professional for this work.

What's the difference between torsion and extension springs? Torsion springs twist above the door and handle most of the lifting work. Extension springs stretch along the sides and assist with lowering. Torsion springs are stronger; extension springs are lighter duty. Your door type determines which you need.

How much does a garage door spring replacement cost? Cost depends on spring type, door weight, and whether one or both springs need replacement. Torsion springs typically cost more than extension springs. Get a free estimate from us to know the exact price for your door.

What happens if a garage door spring snaps? Your door becomes very heavy and hard or impossible to open manually. The opener may struggle or fail. Safety cables (on extension springs) prevent broken coils from flying. Stop using the door and call a professional immediately.
