Why Mountain View's Wet Season Is Harder on Garage Door Springs Than You Think
2026-04-12 7 min read
If you've ever walked into your garage on a January morning and found your door frozen in place. or heard a sharp bang like a gunshot from inside the garage. there's a good chance a spring just gave out. In Mountain View, that scenario plays out more often than homeowners expect, and the timing is almost always tied to the season.
Mountain View sits in the heart of Silicon Valley with a Mediterranean climate: warm, dry summers followed by cool, wet winters. While the weather rarely gets extreme, that seasonal swing from dry to damp. especially the stretch from November through March when most of the city's roughly 20 inches of annual rainfall arrives. creates conditions that quietly wear down garage door springs over time.
How Mountain View's Climate Affects Your Springs
Garage door springs aren't just simple coils of metal. They're precision components under enormous tension, and they're sensitive to moisture and temperature change. During Mountain View's wet season, humidity levels spike. February is typically the most humid month of the year. That moisture gets into uninsulated garages and accelerates surface rust on spring coils.
Rust doesn't just look bad. It creates micro-fractures in the metal that weaken the spring's structural integrity. A spring that might have lasted another two or three years in a dry climate can snap during the first cold spell after a rainy stretch. This is especially true for older homes in neighborhoods like Monta Loma, Blossom Valley, and Waverly Park, where garages built in the 1950s and 1960s often lack proper ventilation or weatherstripping to keep moisture out.
Service calls for broken springs in Mountain View tend to spike at the start of winter and again in early spring. right when temperature fluctuations are most pronounced and springs that weakened over the summer finally give out under the added stress.
Torsion vs. Extension Springs: What's In Your Garage?
Before you can understand what you're dealing with, it helps to know which type of spring your door uses.
Torsion springs mount horizontally on a metal bar directly above the garage door opening. They store energy by twisting when the door closes, then release that energy to help lift the door. Most modern Mountain View homes with sectional doors use torsion springs. They're more durable, last longer, and if they break, they stay contained on the bar rather than flying across the garage.
Extension springs run along the side tracks of older-style doors. They stretch as the door closes and contract to lift it open. They're found on lighter, older doors and tend to be less expensive to replace. but they carry a higher safety risk if they snap, since a broken extension spring can become a projectile.
If your home was built before 1980. common in Mountain View's older neighborhoods. there's a reasonable chance you still have extension springs, especially if the door is a single-car style.
Warning Signs a Spring Is About to Fail
Don't wait for the loud bang. Springs give warning signs before they go:
- The door feels unusually heavy when you try to open it manually. A properly balanced door with good springs should lift with minimal effort. - The door opens unevenly or crookedly, suggesting one spring has weakened more than the other. - Visible gaps or separation in the spring coil. a clear sign the spring has already partially failed. - Squeaking or grinding sounds during operation, especially in winter when moisture has stiffened the coils. - The door reverses or won't open fully, which sometimes happens when a worn spring can't provide enough lift.
If your door has two springs (which most do), and one breaks, replace both at the same time. The surviving spring has experienced the same wear cycle and is likely close behind. Replacing only one sets you up for a second service call within months.
What Does Spring Replacement Cost in Mountain View?
In the Bay Area, spring replacement typically costs more than national averages due to higher local labor rates. For California homeowners, torsion spring replacement generally runs $200 to $500 or more for a single-spring door, including parts and labor. Extension spring replacement is usually more affordable, coming in around $120 to $200 per spring with installation.
If your door is a wide double-car style. common in newer Mountain View homes near Cuesta Park or Shoreline West. expect to pay toward the higher end, since heavier doors require stronger, higher-rated springs.
A few factors that can push the cost higher: - Emergency or same-day service (add $50,$100 or more) - Replacing cables or drums at the same time (often worth doing while the technician is already there) - Converting from extension to torsion springs, which costs $400,$800 but significantly improves safety and longevity

DIY vs. Professional Spring Replacement
This is one garage door repair you should not attempt yourself. Torsion springs are wound under hundreds of pounds of tension. Mishandling them without the right tools can result in serious injury. the kind that sends people to the emergency room. Extension springs carry similar risks if safety cables aren't installed properly.
Professional technicians have the specialized winding bars, proper spring sizing knowledge, and experience to balance the door correctly after installation. An improperly balanced door puts stress on the opener motor and can cause premature failure of other components.

Extending the Life of Your Springs
A few simple habits can help your springs last longer, even through Mountain View's wet winters:
1. Lubricate the springs twice a year. once before the rainy season starts in November, and once in spring. Use a dedicated garage door lubricant spray (not WD-40, which attracts dirt). This reduces friction and helps prevent rust. 2. Test the door balance annually. Disconnect the opener, lift the door manually to waist height, and let go. It should stay put. If it falls or rises, the spring tension is off and needs professional adjustment. 3. Inspect for rust after wet stretches. After a heavy rainy period, take a quick look at your springs. Surface discoloration or flaking is a sign to act sooner rather than later. 4. Keep the garage ventilated. Moisture trapped in an enclosed garage speeds up corrosion. If your garage lacks vents or weatherstripping, addressing those issues protects all your mechanical components, not just the springs.

Frequently Asked Questions
How long do garage door springs typically last in Mountain View?
Most torsion springs are rated for 10,000 cycles. one cycle equals one opening and one closing. In a household that uses the garage door four times a day, that works out to roughly 7 to 10 years. Homes with higher garage usage or poor moisture control may see springs fail sooner. High-cycle springs rated for 20,000 cycles or more are available and worth considering if you're already paying for a replacement.
Can I still use my garage door if a spring breaks?
Technically, some openers can still force the door open with a broken spring, but this puts enormous strain on the opener motor and can cause serious damage. The door also becomes extremely heavy and dangerous to operate manually. The answer for most Mountain View homeowners is: don't. Leave the door in place and call a professional for same-day service.
Should I replace both springs even if only one broke?
Yes. almost always. Both springs have gone through the same number of cycles and have the same level of wear. If one breaks, the other is likely to follow within weeks or months. Replacing both at the same time during a single service call saves money on labor and prevents a second unexpected failure.
