One morning you hit the button on your garage door opener, hear a loud bang, and the door doesn't move. Or it moves partway and stops. Or you come home to find it stuck at an odd angle. In almost every one of those scenarios, the culprit is the same thing: a broken garage door spring.
It's one of the most common calls we get in Chehalis. and one of the most misunderstood repairs. Homeowners often underestimate how central springs are to how their door works, and some try to push through on a bad spring in ways that end up causing significantly more damage. This post is meant to give you a straight, honest picture of what's happening, what it costs to fix, and what you should and shouldn't try to do yourself.
Your garage door looks like it's powered entirely by the electric opener, but that opener motor is actually quite small. The real muscle behind your door is the spring system. Springs counterbalance the weight of the door. which can be anywhere from 130 to over 300 pounds depending on size and material. so the opener only has to manage the remaining load.
There are two spring types you'll encounter:
Torsion springs are the horizontal coiled springs mounted on a bar directly above the door opening. They twist to create stored energy and are the modern standard for most homes. They're more durable, safer when they fail, and easier to control during replacement.
Extension springs run along the horizontal tracks on either side of the door and work by stretching. They're less common on newer installs and carry more risk when they break. without safety cables, a snapped extension spring can go flying. If your home in Chehalis was built before the late 1990s, particularly in older Burlingame neighborhoods with Craftsman-style homes, you may still have an extension spring system.
Most modern torsion springs are rated for 10,000 to 20,000 cycles. If your household uses the garage door four times a day, that's roughly 7,14 years of lifespan. less if corrosion has accelerated the wear, which is a real factor in Chehalis's wet climate.
Springs rarely fail with zero warning. Here's what to watch for:
- The door feels unusually heavy when you lift it manually. Disconnect your opener and try lifting the door to waist height. It should rise smoothly and stay put when you let go. If it feels like you're fighting significant weight, your springs are losing tension. - Visible gaps in the torsion spring coils. A broken torsion spring will have a clear gap somewhere along the coil. it looks like a section of the spring has separated. - The door moves unevenly, rising faster on one side than the other, or the panels look misaligned when closed. - Rust or surface corrosion on the coils. In Chehalis's damp winters, springs are particularly vulnerable to moisture-driven fatigue. Light surface rust is a warning sign; deep pitting means the spring is structurally compromised.
If you catch these warning signs early, you can schedule a replacement on your own timeline. before you end up stuck with a door that won't open at 7 a.m. on a workday.
Here's what you should realistically budget for, based on current pricing data:
For a single-car door with torsion springs, professional replacement typically runs $250,$450, including parts and labor. This is the most common job.
Extension spring replacement usually starts around $200 for a single door. parts are cheaper, but if safety cables need to be added, that brings the cost closer to torsion spring pricing.
For a double-car door, expect to pay more because larger doors require heavier-duty springs. Double-door spring jobs often land in the $350,$600 range.
A few things that affect your final number:
- Spring grade: Economy springs are cheaper upfront but wear out faster. sometimes within five years. Higher-cycle springs (rated for 25,000+ cycles) cost more but are a much better investment for a door that gets heavy daily use. - Replacing one vs. both: If you have two springs and one breaks, most professionals. including us. will recommend replacing both at the same time. Springs wear at the same rate. The second spring is usually close to failure when the first one goes, and doing both in one service call saves you a second labor charge. - Emergency or after-hours calls: If your door is stuck closed and you need urgent service, expect to add $50,$100 for after-hours response.

This is where we're going to be direct with you: garage door spring replacement is one of the few home repairs where the DIY risk genuinely outweighs the savings.
Torsion springs are under extreme tension. hundreds of foot-pounds of torque. If a spring slips or releases unexpectedly during installation, the result can be a serious injury. Proper replacement requires specific winding bars, the correct spring sizing for your door's weight, and experience with tensioning. Getting the tension wrong doesn't just mean the door won't balance. it can cause the door to slam down or the opener to burn out prematurely.
For homeowners in areas like Jackson Highway or out near Adna who might be comfortable with general mechanical work, we understand the impulse to handle it yourself. but this is the repair where calling a professional is the straightforward right call.
A few pieces of information make the service call faster and get you a more accurate quote upfront:
1. How many doors your garage has (single or double) 2. Whether your springs are torsion or extension (torsion = one horizontal bar above the door; extension = springs running along the side tracks) 3. How old the door is and whether the springs have ever been replaced before 4. Any other symptoms. grinding noises, uneven movement, opener straining
You can reach out to us directly to schedule a service call or ask about pricing before you commit. We're also happy to walk through what we found during a service visit so you understand exactly what was replaced and why.
If your opener has been straining for a while due to failing springs, it's also worth reviewing our sensor calibration guide after the springs are replaced. a door that's been running off-balance can sometimes knock sensors out of alignment.

Q: My garage door opened fine this morning and now it won't move at all. Could it really just be a spring? A: Yes, this is exactly how torsion spring failure usually happens. the spring can appear fine during normal operation, then snap under full load. If you hear a loud bang from the garage and the door suddenly won't move or feels extremely heavy to lift manually, a broken torsion spring is almost certainly the cause. Check above the door for a visible gap in the coil.
Q: Should I replace both springs even if only one broke? A: In almost every case, yes. Both springs experience the same amount of wear. If one has failed, the other is typically near the end of its lifespan as well. Replacing both at once costs less than two separate service calls and ensures your door is properly balanced.
Q: How long will new springs last in Chehalis's wet climate? A: Standard springs rated for 10,000 cycles last roughly 7,14 years depending on usage frequency. In a humid climate like ours, lubrication matters. applying silicone spray to the spring coils twice a year reduces moisture-driven corrosion and can meaningfully extend spring life. High-cycle springs rated for 25,000+ cycles are worth the extra cost if you use your garage door frequently.
