If you've ever heard a loud bang from your garage. like something snapped or exploded. there's a good chance a torsion spring just gave out. It happens fast, it's jarring, and it leaves your garage door completely dead in the water. For homeowners in Hermosa Beach, spring failure is one of the most common garage door problems we see, and the coastal environment is a big part of why.
Hermosa Beach sits right between Manhattan Beach and Redondo Beach, smack on the Pacific Ocean. That means your garage door hardware. including the springs. is breathing in salt air 365 days a year. And that matters. <cite index="11-11,11-12">Garage door springs can rust when exposed to moisture, and in coastal regions that rust can degrade the spring over time, rendering it useless.</cite>
The marine layer that rolls in off the water most mornings deposits fine salt particles on every exposed metal surface. <cite index="14-20,14-21,14-22">Rust weakens spring metal and increases friction as the coils rub together, causing corroded springs to fail thousands of cycles before their rated lifespan. and garages in humid or coastal environments experience spring corrosion faster than those inland.</cite>
Most standard torsion springs are <cite index="12-34">rated for 10,000,20,000 cycles, with one cycle equal to opening and closing the door once.</cite> For a family using the garage as a main entry point multiple times a day, that math adds up quickly. Combine that with Hermosa Beach's salt air and you're looking at a shorter-than-average service life. especially for springs that have never been lubricated.
You don't always get the dramatic loud bang as a warning. Often, springs give you plenty of clues before they snap. Here's what to watch for:
- The door feels heavy. <cite index="12-5">Springs may be losing tension, making the opener work harder.</cite> If your door feels like it's fighting you, that's a red flag. - Slow or uneven movement. <cite index="12-6">The door jerks or tilts when opening or closing.</cite> - The door won't stay open. <cite index="12-8">If the door falls when partially raised, the springs aren't counterbalancing properly.</cite> - Visible gaps in the coils. <cite index="13-4">Healthy coils touch each other; visible gaps indicate a spring near failure.</cite> - Loud popping or grinding. <cite index="12-7">Popping or snapping sounds often signal a spring under stress.</cite>

Pricing varies based on the type of spring, the size of your door, and whether you call during regular hours or in an emergency. Here's an honest breakdown:
<cite index="12-2">Torsion springs typically run $150,$350 per spring, including parts and labor.</cite> These are the horizontal coiled springs mounted above the door opening. the most common type in Hermosa Beach homes.
<cite index="12-3">Extension springs cost $100,$200 per spring. slightly less expensive but less durable.</cite> These run alongside the door tracks and are more common on older or lighter doors.
<cite index="11-27">Account for replacing both springs at once, so your door stays balanced and avoids extra repairs.</cite> If one has broken, the other is likely at a similar point in its wear cycle. Replacing both during the same visit saves you a second service call in the near future.
<cite index="16-5,16-6">Scheduling repairs early. when you notice signs of a weakening spring. can prevent damage to other components, like cables or the opener.</cite> Emergency calls after a spring completely fails typically cost more. <cite index="20-26">Left unattended, a $200 job can quickly turn into a $600+ repair involving cables, pulleys, and even the opener.</cite>
If you're replacing springs, it's worth asking about high-cycle options. <cite index="14-27,14-28">Upgrading to high-cycle springs rated for 25,000 to 50,000 cycles costs between $50 and $150 more than standard springs. but the longer lifespan makes the investment worthwhile for frequently used doors.</cite>
For a home in the Sand Section or along The Strand where the door is used multiple times daily and constantly exposed to ocean air, high-cycle springs with a galvanized or corrosion-resistant coating are a smart call. It's the kind of upgrade that pays for itself.
We hear this question a lot: *Can I just replace the springs myself?* The short answer is no. and this isn't just us being cautious. <cite index="12-19,12-20">Springs store significant energy, and one wrong move can cause serious injury. Attempting to install or remove springs without proper training and tools can result in broken parts, damaged property, or even hospitalization.</cite>
<cite index="16-14,16-15">Torsion springs are particularly dangerous to replace because they are tightly wound around a metal shaft above the garage door. releasing or resetting that tension requires specialized tools and careful adjustments.</cite>
A trained technician doesn't just swap the spring. They check cable condition, verify door balance, inspect the opener, and make sure the entire system is working as it should. You can learn more about how springs work and the safety considerations involved in our post on garage door spring safety.
Not all quotes are equal. When getting a service call, here's what a reputable provider should include:
- <cite index="13-9">Inspections of cables, rollers, bearings, and tracks should be included.</cite> - <cite index="13-10">Parts should have a minimum 3,5 year warranty, plus labor coverage.</cite> - <cite index="13-12">Red flags include quotes under $250, high-pressure tactics, no receipts, or cash-only requests.</cite>

Q: How do I know if my garage door spring is broken versus something else? A: The most telling signs are a loud bang followed by a door that won't move, a door that opens only 6,12 inches and stops, or a visible gap in the coil above your door. If the opener motor runs but the door barely moves, a broken spring is the most likely cause. Don't try to force it open. call a technician.
Q: How long does a spring replacement take? A: For most Hermosa Beach homes with a standard two-car door, a professional spring replacement takes about 1,2 hours. If cables or other hardware also need attention, add some time. Same-day service is typically available for non-emergency calls.
Q: Will the coastal salt air keep causing spring problems even after I replace them? A: Yes, to some degree. that's just the reality of living near the ocean. The best defense is lubrication every 3,4 months with a silicone or lithium-based spray, annual professional inspections, and upgrading to galvanized or high-cycle springs when it's time to replace. Staying ahead of maintenance keeps emergency calls to a minimum.
