How much does it cost to repair a garage door spring?

The cost of garage door spring repair in the San Mateo area typically ranges from $150 to $350 for a single spring replacement, and $250 to $500 for both springs. The exact cost depends on the type of spring (torsion vs extension), the size and weight of your door, and whether additional repairs are needed. We always provide a clear, upfront estimate before beginning any work. Torsion springs generally cost more but last longer and provide smoother operation. We recommend replacing both springs at the same time, even if only one is broken, as the second spring is likely near the end of its lifespan as well.

How often should I have my garage door serviced?

We recommend having your garage door professionally serviced at least once a year. During a maintenance visit, our technicians will lubricate all moving parts, check spring tension and door balance, inspect cables and hardware for wear, test safety features, and make any necessary adjustments. Regular maintenance can extend the life of your garage door by years, prevent costly emergency repairs, and ensure safe operation. If you use your garage door more frequently than average (more than 4-5 cycles per day), or if your door is older than 10 years, semi-annual service may be beneficial.

Yes, we offer 24/7 emergency garage door repair services throughout San Mateo County. We understand that garage door problems often occur at the worst possible times, which is why our technicians are available around the clock for urgent situations. Emergency services include broken springs, doors stuck open or closed, off-track doors, and security concerns. Our average response time for emergencies is under 2 hours. Emergency service rates may apply for after-hours calls, but we'll always inform you of the cost before dispatching a technician. Call us anytime at (650) 677-1451 for emergency assistance.

Our technicians are factory-trained on various brands and door types, ensuring we can handle any repair or installation.

How long does a garage door installation take?

A standard residential garage door installation typically takes 3-5 hours, depending on the complexity of the job. This includes removing the old door, installing the new door and hardware, setting up the opener if included, and testing all safety features. Custom installations or commercial doors may take longer. We always aim to complete installations in a single visit and will provide a time estimate during your consultation.

Garage door springs in San Mateo fail silently and without warning. When they snap, your door becomes a 300-pound dead weight that no opener can lift. The two types.torsion and extension.work differently, age at different rates, and require different repair approaches. Understanding which one you have and what to expect can mean the difference between a routine repair and a dangerous emergency.

What Are the Two Types of Garage Door Springs?

Your garage door relies on one of two spring systems. Torsion springs sit horizontally above your door opening and twist under tension. Extension springs run along both sides of the door track and stretch as the door lowers. Most modern homes in San Mateo use torsion springs because they last longer, distribute load more evenly, and pose fewer safety risks during failure.

Torsion springs typically last 7 to 9 years with regular use. Extension springs often fail sooner, around 5 to 7 years. Both types are under extreme tension. A snapped spring doesn't just inconvenience you; it can cause serious injury if you're near the door when it fails. The stored energy releases violently, and a severed spring can whip across the garage at dangerous speeds.

Why Springs Fail in San Mateo's Climate

The Bay Area's coastal air accelerates corrosion. Salt spray, fog, and humidity weaken metal fibers over time. Springs that might last 9 years inland may only reach 6 or 7 years in San Mateo. Rust weakens the spring from inside out, making it brittle and prone to sudden snapping.

Temperature swings also matter. Winter cold makes metal contract; summer heat expands it. Repeated expansion and contraction fatigues the metal. If your garage isn't insulated, this stress compounds. (Learn more about protecting your entire door in our guide to garage door insulation in San Mateo.)

Heavy use accelerates wear too. A door that opens and closes 10 times daily faces twice the stress of one used 5 times daily. Commercial garages and busy households burn through springs faster.

The Real Cost of Spring Replacement

A snapped spring isn't a DIY fix. The tension is lethal. Homeowners who attempt this repair end up injured or worse. A single torsion spring replacement typically costs between $150 and $300, depending on spring quality and whether both springs need replacement. Extension spring repair runs $100 to $200 per spring.

Emergency calls cost more. If your door fails at 8 p.m. on a Sunday, expect a premium. Our emergency garage door service page breaks down what actually costs and when calling a pro makes financial sense.

Some people replace springs one at a time. This is a false economy. Springs age together. If one has snapped, the other is likely near failure. Replacing both at once costs more upfront but prevents a second failure weeks later. A proper estimate for garage door repairs always includes inspection of both springs.

How to Know Your Spring Is About to Fail

A squeaking, grinding, or creaking sound when the door opens signals spring stress. Your opener may struggle visibly. The door might open partway and stick. Some homeowners notice the door closing faster than normal, which happens when spring tension drops.

Don't wait for a complete snap. Call for inspection at the first sign of trouble. A technician can measure spring tension, assess rust, and predict failure. Catching a weakening spring before it breaks costs less than emergency repair and keeps your family safe.

What Happens When You Call a Professional

A qualified technician brings specialized tools and safety equipment. They'll test both springs, check the door balance, and inspect tracks for damage. A snapped spring often damages other components. Your door may need a full system evaluation. Garage Door San Mateo includes a detailed inspection with every spring repair to catch hidden problems.

You'll receive a clear estimate before work begins. No surprises. The repair itself takes 1 to 2 hours. Many jobs qualify for same-day completion if you call before noon.

When to Replace Instead of Repair

Springs older than 9 years should be replaced proactively, even if they haven't failed yet. A new spring costs less than an emergency call plus repair. If your door is over 15 years old, your entire system may benefit from replacement. Older doors often have compatibility issues with new springs, and the opener may struggle with the extra load.

Frequently Asked Questions

Can I replace a garage door spring myself? No. Springs hold hundreds of pounds of tension. Improper removal or installation causes severe injury or death. Always hire a licensed technician with proper tools and insurance.

How long do garage door springs last? Torsion springs typically last 7 to 9 years; extension springs 5 to 7 years. San Mateo's coastal climate shortens this timeline due to rust and salt exposure.

What's the difference between torsion and extension springs? Torsion springs twist horizontally above the door and last longer. Extension springs stretch along the tracks and fail sooner. Torsion is safer and more reliable for residential doors.

Why is spring repair more expensive in an emergency? Emergency calls charge premium rates because they happen outside business hours, require immediate dispatch, and often involve damage from the initial failure that wasn't visible beforehand.

Should I replace both springs at once? Yes. Springs age together. Replacing only the broken one guarantees the other will fail soon after, creating a second emergency. Dual replacement costs more upfront but prevents future breakdowns.
