A customer called last Tuesday morning. Her garage door had dropped halfway down and wouldn't budge. She'd heard a loud bang the night before but assumed it was just wind. When I arrived, I found a snapped spring hanging limp above the door. She was relieved no one was underneath when it failed. That's the reality of garage door springs in Berkeley: they're under extreme tension, and when they break, they break hard. Understanding the difference between torsion and extension springs could save you from a dangerous situation and an expensive emergency call.
Garage door springs are the unsung heroes of your system. They counterbalance the weight of your door, making it light enough for your opener to lift. Without them, your 300 to 400 pound door would crash to the ground. Springs last roughly 7 to 9 years under normal use, though Berkeley's humid climate and temperature swings can shorten that lifespan. There are two main types: torsion and extension. Each works differently, fails differently, and requires different repair approaches.
Torsion springs mount horizontally above your garage door, running along a metal shaft. They twist (or torque) to store and release energy as the door opens and closes. Most modern homes in Berkeley use torsion springs because they're safer, quieter, and more reliable than their counterparts.
When a torsion spring snaps, you'll hear an unmistakable loud bang. The door becomes extremely heavy and your opener won't be able to lift it. A single broken torsion spring means your entire door is stuck. This is when same-day service becomes critical. Never attempt to manually lift the door or force the opener. The spring's tension can cause serious injury, and forcing a disabled door can damage your opener permanently.
Torsion springs typically cost more to replace than extension springs, but they last longer and require less maintenance. If you're curious about the full cost picture, learn what to expect with garage door spring repair pricing in Berkeley.
Extension springs run vertically on both sides of your garage door, usually mounted above the upper door tracks. They stretch and contract to provide counterbalance, storing energy as coils extend. Older Berkeley homes and some budget installations still use extension springs.
The advantage? They're cheaper upfront. The disadvantage? They're less durable, noisier, and more prone to failure. When an extension spring snaps, the door may still operate partially, but it's dangerously unbalanced. One side will drop faster than the other, creating a safety hazard. Extension springs also require safety cables to catch them if they break, adding complexity and maintenance needs.
Extension spring failures are more common because each spring only carries half the load. Over time, that constant cycling weakens the metal. Berkeley's temperature variations from cool mornings to hot afternoons accelerate this wear.

Springs don't just wear out evenly. Several factors accelerate failure in the Berkeley area. Rust and corrosion from moisture damage the metal from inside out. Temperature swings cause metal to expand and contract, creating micro-fractures. Lack of lubrication increases friction and wear. Poor installation or using undersized springs for your door weight creates premature stress.
I've seen countless cases where homeowners ignored early warning signs. A squeaky or creaky garage door, uneven movement, or visible rust on the spring should prompt a professional inspection. Read about the 7 warning signs your door needs professional repair to catch problems early.
If you have a single snapped torsion spring, replacement is your only option. Springs aren't welded or patched in the field. Both springs should be replaced together, even if only one has failed. This ensures balanced operation and prevents the second spring from failing shortly after.
For extension springs, the same rule applies. Replace both at the same time. Mixing old and new springs creates an imbalance that stresses your opener and door tracks.

Never attempt spring replacement yourself. Garage door springs are under 200 to 300 pounds of tension. A slip means serious injury. Professional technicians have the right tools, experience, and insurance to handle this safely. They'll also inspect your entire system, checking tracks, rollers, cables, and opener condition while they're at it.

Regular maintenance extends spring life significantly. Annual lubrication with a silicone-based spray reduces friction. Keep rust at bay with a light coating. Check for visible damage monthly. A professional tune-up catches wear early, before a catastrophic failure strands you in your driveway.
Spring failure is not a question of if but when. The good news? Professional replacement takes a few hours and costs far less than damage to your door, opener, or yourself. Don't wait for the bang. Call us today.
Springs failing? Don't lift that door. Call Garage Door Berkeley at 510-945-3543 or get a same-day estimate. We handle torsion and extension spring replacements across Berkeley and the surrounding area, same day when possible.
How long do garage door springs last? Residential garage door springs typically last 7 to 9 years with normal use. Frequent cycling, humidity, and poor maintenance reduce lifespan. Springs rarely wear out evenly, so expect one to fail before the other despite being installed together.
Can I replace just one spring? No. Always replace both springs at the same time, even if only one is broken. Springs deteriorate together, and using one old and one new spring creates imbalance, stressing your opener and door hardware unevenly.
What's the difference in cost between torsion and extension springs? Torsion springs cost more upfront, typically 25 to 40 percent more than extension springs. However, they last longer, require less maintenance, and are safer overall. Torsion is the better long-term investment for most Berkeley homes.
Is a snapped spring an emergency? Yes. A broken spring makes your door extremely heavy and unsafe. Do not attempt manual lifting or repeated opener use. Call a professional immediately to avoid injury or equipment damage.
Why do springs break in Berkeley specifically? Berkeley's coastal humidity, temperature swings, and moisture accelerate rust and metal fatigue. The cool mornings and warmer afternoons create constant expansion and contraction in the steel, weakening it over time.
