If a snapped spring has left your garage door stuck, or you're wondering what type of spring supports your door, you're asking the right question. Knowing the difference between torsion and extension springs saves you money, prevents unsafe DIY attempts, and helps you understand what happened when something breaks.
Your garage door weighs between 300 and 800 pounds. That weight doesn't stay suspended by luck. Springs do the heavy lifting, and they work in one of two ways.
Torsion springs sit horizontally above your door opening. They twist and unwind like a clock spring, storing rotational energy. One or two torsion springs handle nearly all the load. This design is precise, durable, and requires exact installation.
Extension springs hang on both sides of the door, alongside the horizontal tracks. They stretch and contract like rubber bands. Two extension springs work together to support the weight. This design costs less upfront but wears faster.
Most modern homes in Menlo Park, especially those built in the last 20 years, use torsion springs. They're safer, last longer, and distribute force more evenly. Older homes and some budget installations still use extension springs.
Springs last 7 to 9 years on average. This timeline depends on how often you open and close your door, local humidity, and whether springs receive basic maintenance.
Torsion springs fail when the metal loses elasticity. You'll hear a loud bang, like a gunshot, when one snaps. The door doesn't fall (safety cables prevent that), but it won't open. Extension springs break more quietly, often giving small warning signs before complete failure.
Menlo Park's mild climate is easier on springs than inland areas, but salt air near the coast and morning fog still cause corrosion. Rust weakens metal from the inside out. A spring that looked fine last month can snap during normal use.

A snapped garage door spring creates dangerous stored energy. Torsion springs are under extreme tension. Replacing one without proper equipment can cause serious injury or death. Extension springs can snap back violently and cause the same harm.
Professional technicians use specialized winding bars, torque calculations, and safety equipment. We measure spring wire diameter, coil count, and wind direction. A mismatch of even 5% throws off your door's balance and burns out the opener.
If you've ever handled a stuck garage door, you know how heavy it feels. Springs handle that weight thousands of times. The job demands respect and training. We've seen too many DIY attempts end in emergency rooms and expensive repairs that could have cost half as much if done right the first time.
Our team at Garage Door Menlo Park can assess which type of spring your door uses, determine the exact specifications, and schedule a free quote before we touch anything. Most jobs take two hours. We bring parts, the right tools, and a guarantee on workmanship.
When you call for a same-day estimate, a technician comes to your home and checks:
- Spring type and condition, Wire diameter and spring length, Number of coils and wind direction, Whether both springs are equally worn, Door balance and opener strain, Safety cable condition
A proper estimate breaks down labor, parts, and any additional work your door actually needs. We don't surprise you later with hidden costs.
For pricing details specific to Menlo Park, we've published a full breakdown at our spring replacement cost guide, which shows real numbers and factors that change the final bill.
Springs that receive annual lubrication and inspection often last 10 to 12 years. A small service visit costs far less than emergency replacement. Our maintenance guide walks through what actually matters and what sales pitches oversell.
Check your springs visually once a season. Look for rust, uneven wear, or visible cracks. Listen for grinding or squeaking sounds. Feel for resistance when opening or closing. These small checks catch problems early.
If you live near Menlo Park or in surrounding areas like Palo Alto or Los Altos, spring issues are common. We serve the entire Peninsula and understand how local conditions accelerate wear.
A broken spring isn't an emergency you cause. It's something that happens to every garage door. The difference is how fast you fix it and who you trust with the repair.
Call us at (650) 547-8291 for a same-day estimate. We'll identify your spring type, explain what happened, and tell you exactly what the repair costs before we start. Get in touch today and let's keep your door working safely.
Springs don't last forever, but they should last years. We make sure yours do.
How do I know if my garage door spring is broken? Your door won't open, feels heavier than normal, or you heard a loud bang from the garage. Torsion springs often snap audibly. Extension springs may fail quietly. Either way, stop using the door and call for service.
Can I replace just one spring? We replace both springs at the same time, even if only one snapped. Springs wear together, and replacing one leaves the other to fail within weeks. It's safer and more cost-effective to do both now.
How long does spring replacement take? Most jobs take 1 to 2 hours. We handle measurement, removal, installation, and safety testing. Same-day service is standard when you call before 3 p.m.
What's the difference in cost between torsion and extension springs? Torsion springs usually cost more to replace because installation is more specialized. Extension springs are cheaper parts but wear faster overall. Our estimate compares both options for your specific door.
Do you offer a warranty on spring replacement? Yes. All spring replacements include a one-year parts warranty and a two-year labor guarantee on workmanship. We stand behind every job.
