A customer called last Tuesday asking why a garage door spring replacement quote seemed high. She'd gotten a price from another shop and thought $280 per spring was excessive. I walked her through what actually goes into that number, and she understood immediately. Most homeowners don't know what garage door springs cost in South Pasadena or why prices vary so much between contractors.
The short answer: torsion springs typically run $150 to $400 per spring, depending on the spring's size, material quality, and your door's weight. Extension springs cost slightly less. But that's only part of the picture. Labor, hardware, and whether you need both springs replaced will shift your final bill. See our guide on emergency garage door service in south pasadena: what to do when yours won.
Two main spring types hang above your garage: torsion and extension springs. Torsion springs coil around a shaft above the door opening and handle the lifting work through rotational force. They're stronger, last longer (7 to 9 years, not 10), and cost more upfront. Extension springs run along the sides of your door and use tension. They're cheaper to buy but wear out faster and pose more safety risks when they fail.
A snapped spring can cost you $300 to $500 for one torsion unit, installed. If both springs fail at the same time (common, since they age together), you're looking at $500 to $900 total. Extension spring replacement typically runs $200 to $350 per spring. Read about essential garage door maintenance checklist for homeowners.
The price gap exists because quality matters. A cheap spring from an online marketplace might save you $40 today but snap in four years instead of eight. We source springs built to handle South Pasadena's climate shifts, where summer heat and winter damp cycles stress metal constantly.
Several factors push costs up or down. Your door's weight is the biggest one. A heavy wooden or composite door needs stronger springs than a lightweight aluminum unit. The spring's wire gauge and coil count determine its lifting capacity and longevity.
Installation complexity also matters. Some doors sit in tight spaces or have unusual configurations. Removing old hardware, disposing of the old spring, and installing new cable and pulleys add labor time. A straightforward job takes two to three hours. A tricky one takes longer.

Location matters too. If you're near the foothills in Altadena or closer to the valley, travel time affects the appointment window. Same-day service requests sometimes carry a small rush fee, but we keep it fair because reliability matters more than squeezing an extra charge.
I understand the temptation to save money by ordering a spring online and installing it yourself. Don't. A snapped spring under tension can cause serious injury. The door itself can drop unexpectedly if tension is released wrong. You need the right tools: a spring hook, torque wrench, cable cutters, and safety equipment.
Beyond safety, measuring for the correct spring size requires knowing your door's weight, the current spring's dimensions, and how many cycles it's completed. Get it wrong, and you've bought a spring you can't use. Most online retailers won't accept returns on springs.

Springs are the heart of your garage door system. Replacing them right, with quality parts and proper installation, protects your investment and your family's safety.
How long do garage door springs typically last? Torsion springs last 7 to 9 years with normal use and maintenance. Extension springs wear faster, usually 5 to 7 years. Cycle count (how many times you open and close the door) matters more than calendar years.
Can I replace just one spring if the other is fine? We recommend replacing both at the same time. Springs age together and fail together. Replacing one now means replacing the second in a year or two, costing extra labor fees. Both together is more cost-effective long-term.
What's included in a spring replacement estimate? The estimate covers the spring itself, new cables and hardware, labor, and safety testing. We'll also balance your door and check the opener. Disposal of the old spring is included.
Is there a warranty on replacement springs? Yes. We warranty our springs for 5 years against defects. Installation carries a 2-year labor warranty. Ask us about extended coverage options when you call.
How quickly can you replace springs in South Pasadena? Same-day replacement is available most days. Call (424) 677-0420 before 2 p.m. for next-day service, or request emergency service for urgent needs.
