If you've ever heard a loud bang from your garage in the middle of the night, there's a good chance a spring just let go. It's one of the most jarring sounds a homeowner can experience. and one of the most common service calls we get here in Santa Rosa. Springs are the real workhorses behind your garage door, and when they fail, your door isn't going anywhere.
Given that Santa Rosa sits in the heart of Sonoma County wine country with a Mediterranean climate. warm, dry summers and cool, wet winters. your garage door springs are exposed to a real range of conditions throughout the year. The wet season running from November through February brings elevated humidity and moisture that can accelerate rust on metal components, including your springs. That seasonal moisture cycle is one reason spring failure is so common in North Bay homes.
Your garage door can weigh anywhere from 130 to over 300 pounds depending on its size and material. Springs counterbalance that weight, making it possible for a modest electric opener motor. or your own arm. to lift the door with ease. Without functioning springs, even the strongest opener will struggle and can burn out trying.
There are two main spring types you'll encounter:
Torsion springs mount horizontally above the door opening on a metal bar. They twist to store energy as the door closes, then release that energy to help lift it. Most modern Santa Rosa homes use torsion springs because they're safer and last longer. typically rated for 10,000 to 20,000 open/close cycles, which translates to roughly 7,14 years with average use.
Extension springs run along the sides of the door track and stretch when the door closes. They're more common on older garage doors and lighter single-car setups. They cost less to replace but have a shorter lifespan, and a snapped extension spring without a safety cable can be genuinely dangerous.
If you're in an older neighborhood like Roseland or near the Historic Railroad Square area, there's a real chance your home still has the original extension spring setup from decades ago. It may be worth having a technician take a look during your next scheduled maintenance visit.
Springs rarely fail without warning. Here's what to watch for:
- The door feels unusually heavy when you try to lift it manually. A properly balanced door should feel like about 10,15 pounds of resistance. anything more suggests the springs are losing tension. - Visible gaps in the torsion spring coils. Healthy coils sit flush against each other. A gap means the spring has partially or fully broken. - The door won't stay open halfway. Lift your door to waist height and let go. If it drifts back down, the springs aren't doing their job. - Loud bang from the garage. often heard at night when temperatures drop. This is the sound of a spring breaking under tension. Stop using the door immediately if you hear this. - The opener strains or stops mid-cycle. When springs weaken, the opener has to compensate. That extra strain can burn out the motor if ignored.

Prices vary, but here's a realistic range for most Santa Rosa homeowners:
- Torsion spring replacement: $150,$350 per spring, including labor - Extension spring replacement: $100,$200 per spring - Replacing both springs together: typically $200,$400 for the pair
One piece of advice worth taking: always replace both springs at the same time, even if only one has broken. Springs age together, and the surviving spring is usually close to failure anyway. Replacing them as a pair ensures balanced tension and saves you the cost of a second service call in a few months.
If you're investing in a replacement, ask about high-cycle springs. Standard springs are rated for around 10,000 cycles. Premium high-cycle springs can be rated for 25,000 to 50,000+ cycles. they cost more upfront but can last 15,20 years, making them a smart choice for households that use the garage as the primary entry point.
Also, in a coastal-influenced climate like Sonoma County's, galvanized or oil-tempered springs hold up significantly better against rust. The seasonal rain and humidity Santa Rosa sees from December through March can shorten the life of bare steel springs noticeably.
This needs to be said plainly: garage door spring replacement is not a weekend project. Torsion springs store enormous amounts of energy. enough to cause severe injury or death if they slip during adjustment or installation. Professional technicians use calibrated winding bars and safety equipment specifically designed for this work.
Every year, thousands of homeowners are injured in garage door accidents nationally, and improperly handled springs are a leading cause. The $50,$100 you might save by attempting this yourself is not worth the risk.
If your spring has broken and your door is stuck closed, don't force it open manually or try to run the opener. Contact a qualified technician to assess and repair the system safely.
If your home currently has extension springs and you're replacing them anyway, this is a good time to consider converting to a torsion spring system. The conversion costs more upfront. roughly five times the cost of a like-for-like replacement. but you'll gain better safety, smoother operation, and a longer lifespan. Many Fountaingrove and Rincon Valley homeowners who've rebuilt or renovated post-2017 have already made this upgrade as part of larger garage door updates.

A professional technician can typically complete the job in 45 to 90 minutes, including removing the old springs, installing and tensioning the new ones, testing door balance, and inspecting cables and hardware.
Technically, some openers will attempt to operate with a broken spring. but you shouldn't let them. Running the opener without proper spring support puts enormous strain on the motor and can cause further damage to cables, rollers, and the opener itself. Keep the door closed and call for service.
If the springs look intact but the door is squeaking or moving stiffly, lubrication with a lithium- or silicone-based spray may solve the problem. But if you see visible gaps in the coils, hear loud banging, or the door feels very heavy to lift manually, those are signs of failure. not a lubrication issue. When in doubt, have a technician take a look.
