If you've ever heard a loud bang from your garage early in the morning. like a gunshot from inside the wall. there's a good chance a garage door spring just let go. It's one of the most common calls we get at Garage Door Thousand Oaks, and it catches homeowners completely off guard every time. Understanding how springs work, what warning signs to watch for, and what a realistic replacement costs can save you a stressful, expensive surprise.
Your garage door is heavy. a standard single-car steel door typically weighs 130 to 150 pounds, and a two-car insulated door can top 300 pounds. Springs counterbalance that weight so your opener only has to do a fraction of the lifting. Without functioning springs, your opener motor strains, your cables wear prematurely, and the door simply won't open safely.
There are two main types used in residential garages:
- Torsion springs mount horizontally above the door opening and coil around a metal rod. They're the most common in newer Thousand Oaks homes. - Extension springs run along the sides of the door tracks and stretch to store energy. You'll find these in older homes, including many of the ranch-style and mid-century properties in neighborhoods like Lynn Ranch and Conejo Oaks.
Both types have a finite cycle life. typically 10,000 cycles for standard springs, which translates to roughly 7 to 12 years with normal use. If your home was built in the 1980s or 1990s (as many Lang Ranch and Newbury Park homes were), those original springs may be nearing or past their end of life.
Springs rarely give out without warning. Watch for these signals:
If your opener sounds like it's working hard, or the door jerks and moves slowly, the springs may have lost tension. A balanced door should stay open on its own at about halfway. if it drifts down, the springs aren't doing their job.
On a torsion spring, healthy coils sit tight against each other. Visible gaps in the coil are a clear sign of a spring that's near failure or already broken.
Thousand Oaks has a Mediterranean climate. mild and mostly dry. but coastal moisture from the Pacific can reach inland areas, especially in Newbury Park and Westlake Village. Moisture accelerates rust on springs, which weakens the metal and shortens the spring's lifespan. If you see orange-brown rust forming, it's time for an inspection. You can apply a lithium-based lubricant annually to slow corrosion, but heavy rusting means replacement is coming.
If the motor runs but the door stays put, or if the door drops faster than normal, a spring has likely failed completely. Stop using the door immediately. operating a garage door with a broken spring puts serious strain on every other component and can damage your opener within a few cycles.

This is not a project for YouTube tutorials and a wrench from the garage. Torsion springs are wound under extreme tension. if one releases unexpectedly during adjustment, it can cause serious injury or destroy the door system. Professional technicians use specialized winding bars and know how to release tension safely. The risk simply isn't worth the savings. Our services page has full details on what a spring replacement visit includes.
For Southern California, expect to pay roughly $200 to $400 per spring including labor, with most homeowners spending in the $300 to $500 range for a full replacement on a standard single-car door. A dual-spring replacement on a two-car door typically runs $400 to $700 or more depending on spring quality and whether cables need attention at the same visit.
A few things that affect your final price:
- Spring type: Torsion springs cost more than extension springs but last significantly longer. - Spring quality: Standard springs rated for 10,000 cycles are cheaper upfront, but high-cycle springs rated for 25,000 to 50,000 cycles cost modestly more and can last 15 to 20 years. often the smarter investment for a home you plan to stay in. - Replacing one vs. both: Even if only one spring breaks, most technicians recommend replacing both at the same time. The second spring has experienced the same wear and tear and will likely fail soon anyway. replacing both now saves you a second service call. - Cable replacement: If the cables show fraying or uneven wear, bundling that repair into the same visit typically costs less than scheduling separately.
If you're also weighing whether to repair your existing door or invest in a new one entirely, our guide on repair vs. replacement decisions for Thousand Oaks homeowners walks through that math clearly.
1. Don't force the door. manually or with the opener. You risk cable damage, bent tracks, and destroying your opener motor. 2. Use the emergency release cord only if you need to get your car out, and only if you can safely lift the door by hand with help from another person. 3. Call a local technician. a broken spring is typically a same-day repair. Most reputable shops carry the common spring sizes on their trucks.

Standard springs are rated for about 10,000 cycles, which works out to roughly 7 to 12 years with typical daily use. Homes in areas with more coastal humidity, like parts of Newbury Park near the Dos Vientos area, may see slightly shorter lifespans due to moisture-related corrosion. Upgrading to high-cycle springs at replacement time is often worth the modest extra cost.
No. and you really shouldn't try. Operating a door with a failed spring puts immediate strain on the opener motor and can cause cable failure or track damage within just a few uses. Leave the door in place and call a technician.
Yes, in almost every case. Both springs experience the same wear over the same number of cycles. If one has broken, the other is typically close behind. Replacing both at the same visit saves on labor costs and prevents a second breakdown soon after.
