Garage Door Springs in San Mateo: When to Repair vs. Replace
2026-05-15 7 min read A2Z Garage Doors
Most homeowners don't think about garage door springs until something breaks. Then you're stuck with a door that won't open, a bill you didn't budget for, and questions about whether a repair makes sense. The good news: understanding your springs now helps you avoid panic decisions later.
What Are Garage Door Springs and Why They Matter
Your garage door weighs 300 to 500 pounds. Springs counterbalance that weight, making it possible for your opener to lift the door smoothly. Without functioning springs, your garage door becomes a safety hazard and a genuine inconvenience.
Two main types exist: torsion springs sit above the door and twist to provide lift, while extension springs run along the sides and stretch. Torsion springs are more common in modern homes and typically last 7 to 9 years with normal use. That lifespan depends on how often you open and close the door, local climate stress, and maintenance habits.
A snapped spring doesn't mean your entire system is ruined. It means one component failed, and you need to decide: repair or replace the whole assembly?
Signs Your Springs Need Attention
Listen for a loud bang or crack from the garage. That's often a spring breaking under tension. After that sound, your door will either stop moving or fall suddenly. Don't force it open or try DIY fixes. Springs are under extreme pressure and can cause serious injury.
Other warning signs include slow door movement, the door stopping midway, or a visible gap in the spring. If you notice any of these, check our guide on 5 warning signs you need garage door repair for a full checklist.
Repair vs. Replace: The Cost Reality
Replacing a single snapped spring costs between $150 and $300 in San Mateo, depending on spring type and your door's size. Sounds reasonable, right? Here's where many homeowners get caught off guard: if one spring has failed, the other is likely close behind. Springs wear together.
Replacing both torsion springs at once runs $300 to $600. Yes, it's more upfront. But replacing one spring now and another in six months costs more in service calls and labor fees. We recommend getting a free estimate that covers both springs, so you know the real expense before committing.

Extension springs are cheaper to replace (typically $100 to $200 per spring), but they're less common in newer homes. Your garage probably has torsion springs if your door was installed in the last 15 years.
Why DIY Spring Replacement Is a Bad Idea
Springs are not a DIY project. The tension is extreme. A slip, a miscalibration, or a moment of inattention can result in serious cuts, broken bones, or worse. Professional technicians have specialized tools and training. They also guarantee their work.
If a spring breaks after repair, a licensed company will fix it again at no charge. You won't get that protection doing it yourself. The cost savings disappear the moment something goes wrong.
