If your garage door won't open or you hear a loud bang from the garage, a snapped spring is likely the culprit. These metal coils do the heavy lifting, but they wear out fast. In this post, I'll walk you through what goes wrong, what repairs cost, and why calling a pro beats a DIY fix every time.
Garage door springs operate under intense tension. A typical residential door weighs 300 to 500 pounds. Those springs counterbalance all that weight thousands of times per year. Over time, metal fatigue sets in.
Most springs last 7 to 9 years with normal use. In Daly City's foggy, salt-laden coastal air, that timeline can shrink. Moisture and salt corrode the metal faster than in inland areas. I've pulled springs off homes near the coast that failed at year six.
Two main types exist: torsion springs (mounted above the door) and extension springs (on the sides). Torsion springs are more common in newer homes and tend to last longer. Extension springs are cheaper upfront but wear quicker. When one snaps, the whole door becomes a safety hazard.
A groaning or creaking sound when the door opens is your first warning. The opener might struggle to lift the door, or it stays stuck halfway. You might also notice the door closing faster on one side. These aren't just annoying. A weak or snapped spring can cause the door to drop suddenly, damaging your car or worse.
If you spot these issues, don't force the door open manually. Call for help right away. Check out our guide on 7 warning signs your garage door needs professional repair to catch other problems early.
A single torsion spring replacement typically runs $150 to $300 for parts and labor. Extension springs are cheaper, usually $100 to $200. If both springs have failed, double that cost. An estimate is always free when you call us.
Same-day service is possible if you reach out before noon. We stock common spring sizes and can dispatch a truck to your Daly City home within hours. Waiting a week turns a minor repair into a major inconvenience.

Sometimes the door itself is the problem, not just the spring. If your door is over 15 years old and the springs have failed twice, replacement often makes financial sense. A new door with new springs and hardware costs $1,200 to $3,500 but comes with a warranty and modern safety features.
For newer doors with a first spring failure, repair is the right call. You're investing in a component that has many years left. Our team at Garage Door Daly City will be honest about whether your door is worth fixing. We've seen too many homeowners replace doors that only needed spring work.

I've been on trucks for 15 years, and I've seen homeowners hurt trying this job. Springs are under massive tension. If a tool slips or you misjudge the coil, the spring can snap and cause serious injury. Hospitals in the Bay Area treat dozens of garage door injuries every year.
Professional installation requires special tools, safety equipment, and years of training. The cost of a repair visit (typically $200 to $400) is nothing compared to an ER bill or worse.
Regular maintenance extends spring life. Lubricate springs and hinges twice a year with silicone spray. Keep the tracks clean and aligned. A door that moves smoothly puts less stress on springs.
If you live near the coast, wipe down springs after coastal wind or fog events. Salt spray accelerates corrosion. These small steps add a year or two to spring life.

How do I know if my garage door spring is broken? Listen for a loud bang or popping sound coming from the garage. The door may not open at all, or it opens slowly and unevenly. Some doors close faster than normal. If you see visible gaps in the spring or notice rust, that's a red flag too.
Can I replace a garage door spring myself? No. Springs are under extreme tension and can cause serious injury if they snap unexpectedly. Professional technicians use specialized tools and safety procedures. This is one repair you should always outsource to a trained expert.
How much does a garage door spring cost in Daly City? A single torsion spring typically costs $150 to $300 installed. Extension springs run $100 to $200. Both springs failing costs roughly double. Call us for a free estimate based on your specific door and spring type.
How long do garage door springs last? Most springs last 7 to 9 years with normal use. Coastal areas like Daly City see faster wear due to salt and moisture. A spring that fails early may indicate poor maintenance or a low-quality original part.
Can I still use my garage door if one spring is broken? No. A broken spring throws the door off balance and makes it unsafe. The door could drop suddenly and damage your car or injure someone. Use the pedestrian entry until you've had a professional repair it.
