If you've noticed your garage door moving unevenly or heard a loud snap, a broken spring is likely the culprit. Replacing garage door springs in Redwood City typically costs $150 to $400 per spring, depending on type and labor. The real budget shock comes when homeowners don't know what drives that price, or they wait too long and damage the door itself.
Garage door springs carry immense tension. A torsion spring above your door stores energy equivalent to a small car's weight. When one fails, the other compensates, working twice as hard until it snaps too. That's why single spring replacement often leads to a second failure within weeks.
Most homes have either torsion springs (one or two above the door) or extension springs (one on each side). Torsion springs cost more to replace because installation demands precision and specialized tools. A single torsion spring runs $200 to $400 installed. Extension springs are cheaper, typically $150 to $300 per pair, but they wear faster and need more frequent replacement.
Labor accounts for half your bill. A technician must safely release tension, remove the old spring, install the new one, and balance the door. This takes 1 to 2 hours and requires liability insurance. Cheap labor often means inexperienced work, leading to misaligned doors or premature failure.
Spring material itself costs $50 to $150 per unit. The rest goes to the technician's expertise and equipment. Some companies charge a service call fee (around $50 to $100) before quoting. Garage Door Redwood City includes the call fee in the final estimate, so you're never guessing at the real cost.
If you're considering DIY, stop. A snapped spring under tension can cause serious injury. The door itself can crash down, damaging your car or anything beneath it. Professional installation protects your home and your body.

Replace both springs at the same time, even if only one failed. A second failure within weeks will cost you another service call. Replacing both upfront saves money and frustration. Most technicians offer a small discount (10 to 15 percent) for replacing a pair.
Schedule service early in the day or mid-week. Weekend and evening calls carry premium charges. If your door is stuck, use the manual release lever to open it partially, reducing stress on the remaining spring. This buys you time to get a competitive quote.
Get written estimates from at least two companies. Ask if they include a warranty on parts and labor. Most reputable shops offer one year on springs and two years on installation. Cheap providers often skip warranties entirely, leaving you exposed to quick failure.

Extension springs fail more often, typically every 5 to 7 years. Torsion springs last 7 to 9 years. Over a 15-year period, you'll replace extensions twice and torsion once. Torsion's higher upfront cost pays off in fewer replacement cycles and less downtime.
Your door's age and weight also matter. Heavy wooden doors need stronger springs, which cost more. Aluminum or vinyl doors use lighter springs, reducing replacement expense.
Springs don't truly repair. Once snapped, they must be replaced. Some technicians will try selling you "spring stretching" or "reinforcement," but these don't work. A broken spring is a broken spring.
What you can do is maintain your door to extend spring life. Regular lubrication, balance checks, and opener adjustments reduce strain on springs. Check out garage door maintenance to stop repairs before they start for a seasonal checklist.
If your door moves slowly, jerks to one side, or opens only partially, a spring is likely weakening. Get a free inspection before it snaps and leaves you stranded. A preventive replacement costs the same as emergency service but avoids the stress.

How long do garage door springs last? Most springs last 7 to 9 years with regular use. Frequency of opening and lubrication affect lifespan. Poorly maintained springs fail as early as 5 years. Proper maintenance extends life closer to 10 years.
Can I replace just one spring if both are old? Technically yes, but not recommended. If one spring failed, the other is under extreme stress and will likely snap within weeks. Replacing both together is safer and more economical long-term.
Why is professional spring replacement so expensive? Springs operate under 200+ pounds of tension. Improper release can cause serious injury or property damage. Professional technicians carry liability insurance, use specialized tools, and guarantee their work. This expertise and safety justification the cost.
What's the difference between torsion and extension springs? Torsion springs sit above your door and twist to store energy. Extension springs run along the sides and stretch. Torsion is more durable but costs more upfront. Extension is cheaper but needs replacement more frequently.
Does homeowner's insurance cover spring replacement? Usually no. Springs are considered wear and tear, not sudden damage. Check your policy, but expect to pay out of pocket. Regular maintenance can sometimes reduce replacement frequency enough to offset the cost.
