Here's what most homeowners don't realize about garage door springs: they're under constant tension, holding roughly 400 pounds of weight even when the door sits still. When one fails, your entire door becomes a safety hazard. In 15 years on the trucks, I've seen too many DIY attempts end badly. Let me walk you through what to watch for, why replacement matters, and when to call a pro in Redwood City.
Your garage door relies on two types of springs: torsion and extension. Torsion springs sit above the door on a horizontal rod and use rotational force to lift the weight. Extension springs run along the sides and stretch to provide lift. Both are engineered to cycle around 10,000 times over their lifespan, which usually translates to 7 to 9 years of typical household use.
The trade-off is real. Springs compress and extend thousands of times, handling tremendous load. Metal fatigues. Eventually, a snapped spring is inevitable. The question isn't if, but when and whether you'll catch it before someone gets hurt.
A broken or weakening spring shows itself clearly if you know what to look for. Your door might open only partway before stopping. It could slam shut harder than usual. Some homeowners report hearing a loud bang or crack before the door stops working entirely.
Another red flag: the door feels heavier when you try to open it manually. If the opener runs but the door barely moves, a spring is likely the culprit. Don't ignore these signals. A snapped spring puts extra strain on your opener, which can accelerate other repairs down the line.

I get it. You want to save money. But replacing torsion springs yourself is one of the few garage door jobs I'll tell you to avoid outright. These springs are under extreme tension. Releasing that pressure improperly can cause serious injury or death. I've seen hands crushed, faces cut by flying hardware. It's not worth it.
Extension springs are slightly safer but still risky. A professional has the right tools, safety equipment, and experience to handle the job correctly. We can also inspect the rest of your door while we're at it. Worn pulleys, cables, or rollers often go unnoticed until they fail too. Our complete garage door tune-up and inspection guide covers everything that should be checked.
Here's the honest breakdown. A single torsion spring replacement runs between $150 and $300 in Redwood City, depending on the spring size and your door weight. Both springs replaced typically cost $300 to $500. Extension springs cost less (around $100 to $200 per spring) but your door might have two, so plan accordingly.
The estimate is always free. Call us, describe what's happening, and we'll give you a straight answer on cost before we touch anything. Same-day service is usually available, and most jobs are done within an hour. Waiting around for weeks isn't necessary.
When your spring breaks, you want someone who can respond quickly and do it right. Garage Door Redwood City handles emergency calls regularly. We know the neighborhoods, the door types, and the issues specific to our coastal climate. Salt air and humidity can accelerate spring wear in the Bay Area compared to inland.
If you're noticing early signs of wear, don't wait for a complete failure. Schedule a free quote today and let's assess what you're dealing with. Prevention beats emergency calls every time.
Ignoring a failing spring puts stress on your opener motor. It forces cables to work harder. Rollers and tracks bear extra load. One failed component often triggers a cascade of repairs. What started as a $300 spring job becomes a $1,200 project when the opener burns out or the door derails.
Don't put yourself in that position. If you suspect a spring issue, get it checked. Our team can review your door's overall safety and maintenance needs at the same time.
Your garage door should work smoothly for years. Broken springs end that fast. Contact Garage Door Redwood City at 626-635-2537 or get a same-day estimate online. We'll get you back to normal.
How long do garage door springs last? Torsion and extension springs typically last 7 to 9 years with regular use. That's roughly 10,000 door cycles. Factors like climate, humidity, and how often you use the door affect lifespan. Coastal Redwood City humidity can shorten spring life slightly.
Can I replace just one spring if both are old? Technically yes, but I don't recommend it. Paired springs age similarly. If one has failed, the other is near the end too. Replacing both at once avoids a second service call within months and ensures balanced door operation.
What's that loud bang when my door stops working? That's usually a snapped torsion spring releasing its tension suddenly. The sound is startling but normal. Don't use the door and call a technician immediately. The opener is now doing all the work unsupported.
Is spring replacement covered under warranty? Most door manufacturers warranty springs for 1 to 5 years against defects. Age and normal wear aren't covered. Your homeowner's insurance typically doesn't cover springs either. Ask us about pricing when you call.
Should I replace springs on an old garage door? If the door is 15 plus years old, consider whether replacement makes sense overall. Sometimes a new door costs less than multiple repairs. We can advise based on your specific situation.
