A customer called last Tuesday saying her garage door wouldn't open. When we arrived, the torsion spring above the door was snapped clean in half. She'd never heard the term "torsion spring" before that moment. The good news: understanding which type you have, and what it costs to replace, takes just a few minutes. That knowledge saves you hundreds in unnecessary repairs or panic-driven overspending.
Most garage doors use one of two designs. Torsion springs mount horizontally above the door opening. They twist and unwind as the door moves, doing about 90% of the lifting work. Extension springs hang vertically on each side of the door. They stretch and contract, pulling the door up through a pulley system.
Torsion springs typically last 7 to 9 years with normal use. Extension springs might reach 5 to 7 years. Both wear faster in Daly City's salty, foggy climate. Rust and salt air accelerate deterioration, which is why maintenance matters year-round here.
Cost differs too. A single torsion spring replacement in the Daly City area runs $150 to $300 per spring, plus labor. Extension springs cost $100 to $200 each. If you have two extension springs (most common setup), expect double that price. Labor adds another $100 to $200 on top. If you need an estimate before committing, we offer free inspections.
Torsion springs are precision-engineered. They handle higher torque and distribute weight more evenly across the door. That engineering costs more upfront, but the longer lifespan justifies it. You won't replace them as often.
Extension springs are cheaper initially. However, they work harder individually because there are usually two of them splitting the load. That constant tension means they fatigue faster. You might find yourself replacing them twice in the time one torsion spring would last.
Here's what often surprises homeowners: when one torsion spring snaps, the other is usually close behind. Springs age as a pair. Replacing just one leaves you vulnerable to a second failure in weeks. Our team always recommends replacing both at once, even if only one broke. It costs more today but saves you from another emergency call next month.

Metal fatigue is the main culprit. Springs compress and extend thousands of times each year. The metal eventually loses its elasticity and cracks. Nothing you do prevents this; it's inevitable wear.
Rust accelerates the process. Salt air in Daly City and nearby coastal communities eats through spring coatings. An unlubricated, rust-spotted spring can fail 2 to 3 years earlier than a well-maintained one. Regular lubrication with garage-door-grade oil slows this decay significantly.
A snapped spring leaves your door stuck or dangerously off-balance. Do not try to open it manually or force the opener. A 300-pound door without spring support can crash down and cause serious injury. Call a professional. Same-day emergency repair is available in Daly City if you need it urgently.
When you schedule a free inspection, we'll identify which type of spring you have and assess both springs' condition. We measure the spring's wire diameter, length, and the number of coils to ensure exact replacements. A wrong-sized spring won't work safely.
The estimate will include parts, labor, and any additional work like cleaning rust or replacing damaged brackets. If you've never seen our garage door repair estimate guide, it breaks down what's reasonable to pay and where costs often surprise people.

You can't stop springs from aging, but you can slow it down. Apply silicone-based lubricant to springs twice yearly. Wipe away dirt and salt residue monthly. Have a professional inspect springs during routine maintenance. We can schedule a service call to keep everything running smoothly and catch wear before it becomes an emergency.
Most snapped-spring emergencies happen in the early morning or late evening when homeowners rely on the opener most. Plan ahead. Budget for spring replacement within your garage door maintenance cycle. It's far cheaper than an emergency call rate.

Q: Can I replace just one spring if only one snapped? A: Technically yes, but not recommended. When one spring fails, the other is nearing the end of its life. Replacing both at once saves you from a second emergency call within weeks.
Q: How do I know if I have torsion or extension springs? A: Look above your garage door opening. Torsion springs run horizontally across the top. Extension springs hang vertically on each side along the tracks.
Q: Are garage door springs covered by warranty? A: Most springs come with a 1 to 5-year warranty against manufacturing defects. Normal wear is not covered. Check your paperwork or ask during your estimate.
Q: How much does emergency spring repair cost in Daly City? A: Same-day emergency service typically adds $50 to $100 to the regular repair cost. It's worth it if your door is completely non-functional.
Q: Can I lubricate springs myself to extend their life? A: Yes. Use garage-door-specific lubricant, not WD-40. Apply a light coat twice yearly to slow rust and fatigue, but this doesn't prevent eventual replacement.
