Garage Door Spring Types in Lynnwood: Torsion vs. Extension Explained

7 min read

Here's what most homeowners don't realize about garage door springs: they're not all the same. Most Lynnwood homes run either torsion or extension springs, and the two work in completely different ways. If one fails, you can't just swap in the other type. Understanding which system you have, how it functions, and when it's headed for trouble will save you money and keep your door working safely.

What Are Garage Door Springs?

Springs counterbalance the weight of your garage door. Without them, your opener would have to lift the full door weight every single time. A typical single-car door weighs 300 to 400 pounds. That's why the springs are under extreme tension. They store energy and release it as your door opens and closes, thousands of times per year. See our guide on weather stripping & seals in lynnwood: stop drafts before winter hits.

Over time, that constant cycle weakens the metal. Springs last roughly 7 to 9 years under normal use. After that, fatigue sets in. A snapped spring doesn't just leave you stuck. It can also damage your opener and create a genuine safety hazard.

Torsion Springs: The Most Common Type

Torsion springs mount horizontally above your door opening. When your opener pulls the cable, the spring twists (torsion) to lift the door. This design is smooth, balanced, and very efficient. Read about garage door insulation in lynnwood: what it actually costs and saves.

Torsion springs come in two main configurations: single-spring and dual-spring setups. Most residential doors in Lynnwood use a single torsion spring. Heavier or commercial doors need two springs working together.

The big advantage of torsion springs is precision. They wear more evenly than extension springs, and they take up less space. If you have a narrow garage or limited headroom, torsion is often the only practical choice. When a torsion spring fails, the door usually stays in place (though you'll need repairs before using it again).

Extension Springs: The Alternative

Extension springs run along both sides of your door, inside the upper tracks. They stretch and contract as the door moves. When the door closes, the springs extend. When it opens, they contract and help lift the weight.

Extension springs require safety cables running through the center of each spring. If an extension spring snaps, the cable catches it and prevents it from flying across your garage. That's critical for safety. A broken extension spring without a cable becomes a projectile that can cause serious injury or property damage.

Extension springs cost less upfront than torsion springs, but they wear faster because they work in a linear motion rather than rotational. They also need more frequent lubrication to stay quiet and functional. If you're hearing squeaking or creaking from your garage door, worn extension springs are often the culprit.

Signs Your Springs Are Failing

A snapped spring is obvious: your door won't open, or it opens partway then crashes down. But warning signs appear before total failure.

Listen for noise. Creaking, squeaking, or grinding from the top of your door usually means springs are losing tension. Check your door's balance by opening it halfway manually. If it won't stay put and slowly creeps down or up, a spring is weakening.

You might also notice your opener struggling. If the door opens slowly, jerks, or stalls partway up, the springs aren't counterbalancing properly. Your opener then works overtime to compensate, which shortens its lifespan. We've written more on when to replace your garage door opener in Lynnwood if you're seeing these signs.

Repair vs. Replacement Costs

A single torsion spring replacement typically costs between $150 and $300 for the part and labor combined, depending on your door's weight and spring quality. Extension springs run slightly less. But these are estimates. Your actual cost depends on your specific setup, whether you need one or two springs, and local labor rates in the Lynnwood area.

Don't attempt DIY spring replacement. Springs are under hundreds of pounds of tension. If a spring slips off its mount, it can cause serious injury. Our team handles this safely and backs the work with a warranty. Get a free estimate for your garage door springs to see exactly what you'll pay.

Frequently Asked Questions

How long do garage door springs last? Torsion and extension springs typically last 7 to 9 years with normal use. The lifespan depends on door weight, frequency of use, and maintenance. Springs that receive regular lubrication tend to last longer than neglected ones.

Can I replace just one spring if I have two? Not recommended. If you have dual springs, both are the same age and wear at similar rates. Replacing only one leaves the other about to fail, causing imbalance and uneven door movement. Replace both at the same time for safety and smooth operation.

What's the difference between a snapped spring and a weak spring? A snapped spring breaks completely, stopping your door from opening. A weak spring still functions but loses tension gradually. You'll notice the door slowing down or the opener working harder. Weak springs need replacement soon to prevent sudden failure and opener damage.

Is spring replacement dangerous to do myself? Yes. Springs hold hundreds of pounds of tension. Incorrect handling can cause the spring to release suddenly, causing serious injury or death. Always hire a licensed technician for spring work. It's not worth the risk.

Do I need to replace my door if the springs fail? No. Springs are a separate component and can be replaced independently. Your door panels and frame are usually fine. Only the springs need replacement unless the door itself has damage or rust that prevents safe operation.
