Garage Door Springs in Glendora: Torsion vs. Extension Explained
2026-08-07 5 min read Michael Rodriguez
Your garage door springs are the unsung workhorses of your home. These metal coils counterbalance your door's weight, making it easy to open and close. Most Glendora homeowners don't think about them until one snaps. Here's what you need to know to avoid costly mistakes and unnecessary spending.
Understanding Spring Types
There are two main types of garage door springs: torsion and extension. Knowing the difference helps you budget accurately and communicate clearly with repair technicians.
Torsion springs wind around a shaft above your garage door opening. They twist to store energy as your door lowers, then unwind as it rises. These are the standard in most modern homes because they wear more evenly and last longer. Torsion springs typically run 7 to 9 years before needing replacement.
Extension springs hang vertically on either side of your door. They stretch as the door lowers and contract as it rises. Extension springs are cheaper upfront but wear faster than torsion springs, often needing replacement every 5 to 7 years.
The cost difference matters when you're budgeting for repairs. A torsion spring replacement costs more initially, but you'll replace it less often over time. An extension spring costs less per job but you'll buy more replacements throughout your home's life.
Which Type Do You Have?
Look above your garage door opening. See a metal shaft with coils wound around it? That's torsion. See vertical springs on both sides of the door? Those are extension springs. When you're ready for a service estimate, knowing this detail saves time on the phone.
Spring Replacement Costs and Estimates
Garage door spring costs vary based on type, quality, and labor in your area. In Glendora and surrounding communities, expect these rough ranges:
- Torsion spring replacement: $200 to $400 per spring, Extension spring replacement: $100 to $200 per spring, Service call and labor: $100 to $150
Most doors have two springs working together. If one snaps, both are near the end of their life. Replacing both at once prevents a second expensive service call within months. This is actually the budget-smart move, even though it costs more upfront.
Always request a written estimate before work begins. Reputable companies like Garage Door Glendora provide estimates at no charge, so you can compare prices without surprises.

DIY vs. Professional Help
Springs are under extreme tension. A snapped spring can cause serious injury. This isn't a DIY project for most homeowners, even if you're handy with other repairs.
Professional technicians have specialized tools, insurance, and years of experience. They work safely and fast. A same-day spring replacement takes 1 to 2 hours and costs far less than an emergency room visit.

Protecting Your Budget Long Term
Schedule an inspection every 1 to 2 years. A technician can spot wear before springs fail completely. This prevents inconvenient breakdowns and lets you replace springs on your timeline rather than during an emergency.
Keep a small maintenance budget aside. Springs are consumable parts, like brake pads on a car. They wear out eventually, no matter how well you care for them. Budgeting $200 to $400 annually means you're never blindsided by replacement costs.
