If you've lived in Antioch for any length of time, you know the summers here are no joke. Temperatures routinely climb into the upper 90s and beyond. and that dry, punishing heat doesn't just bother the people living here. It takes a real toll on the mechanical components of your garage door, especially the springs.
Most homeowners don't think about their garage door springs until something goes wrong. But understanding how Antioch's climate affects these components can save you from a very inconvenient. and potentially dangerous. breakdown.
Antioch sits in Eastern Contra Costa County where summers are long, hot, and arid. Temperatures regularly exceed 90°F from June through September, and occasional triple-digit days are not unusual. That kind of heat does something specific to metal: it causes expansion.
When garage door springs heat up, the metal expands and can lose tension, affecting the door's balance. Then when temperatures drop in the evening or during our mild winters, that same metal contracts. This constant expansion-and-contraction cycle. repeated day after day, season after season. accelerates wear in a way that most standard spring ratings don't fully account for.
Cities nearby, like Brentwood and Pittsburg, experience nearly identical inland heat patterns, so this is a regional issue for East Contra Costa homeowners, not just an Antioch quirk.
Torsion springs mount horizontally above the garage door and twist to generate lifting force. They tend to be the more durable option, typically rated for 10,000 to 15,000 cycles under normal conditions. Most modern homes in Antioch's newer neighborhoods. Lone Tree Valley, Deer Valley, Sand Creek. were built with torsion spring systems. If you're in one of these subdivisions with a two-car garage, this is almost certainly what you have.
Extension springs run along the sides of the door track and stretch as the door opens. They're common on older single-car garages and lighter doors. Extension springs generally have a shorter lifespan. roughly 7,000 to 10,000 cycles. and are more susceptible to environmental stress. If your home was built in the 1980s or early '90s in an older part of Antioch, you may still have extension springs on your system.
Regardless of type, heat and weather conditions are a genuine factor. High temperatures can cause springs to lose tension and affect door balance, while the winter rainy season. Antioch averages most of its precipitation in December through February. introduces moisture that can lead to rust and corrosion on unprotected metal.
The honest answer: somewhere between 7 and 12 years under typical use, assuming the door is operated roughly 3,4 times per day. That works out to approximately 10,000 cycles. But in Antioch's climate, a few factors can push that number lower:
- Extreme summer heat causes metal fatigue over time as the spring repeatedly expands under load - Seasonal moisture during winter storms can accelerate rust if springs aren't properly lubricated - Heavy doors. particularly wood carriage-house styles that are popular in Antioch's Country Hills and Black Diamond Estates neighborhoods. put extra strain on springs, shortening their lifespan
If your door is approaching the 7-year mark, it's worth having it looked at before it becomes a problem. Check our complete DIY maintenance checklist for a walkthrough of what to inspect yourself between professional visits.
Don't wait for a loud bang in the garage to take action. Here are the signs to watch for:
- The door feels unusually heavy when you try to open it manually - Jerky or uneven movement when the door opens or closes - Visible gaps between coils on a torsion spring (a clear sign it has broken) - Squeaking, grinding, or popping sounds during operation - One side of the door rising faster than the other, indicating uneven spring tension - Rust or discoloration visible on the spring surface
If you notice any of these, stop using the door and call a professional. A spring under high tension that snaps can cause serious injury. This is one repair that is genuinely not safe to attempt on your own. even if you're handy around the house.

The good news: there are a few simple things that can meaningfully extend spring life in Antioch's climate.
1. Lubricate springs every 3,6 months using a silicone-based lubricant. Avoid WD-40 or oil-based products. they attract dirt and actually accelerate wear. This is especially important before summer heat sets in and again after the wet winter months.
2. Test your door's balance by disconnecting the automatic opener and lifting the door halfway manually. It should stay in place on its own. If it drops or rises, your springs are out of balance and need adjustment.
3. Inspect for rust after winter rain. If you spot any discoloration or flaking on the spring coils, get a professional to take a look before summer stress makes it worse.
4. Don't ignore small noises. A new squeak or grinding sound during operation is usually the first sign something is off. Catching it early is almost always cheaper than waiting.
If your springs are getting up there in age or you've noticed any of the symptoms above, the team at Garage Door Antioch is available to inspect your system and give you an honest assessment. You can schedule a service call here. no pressure, just a straight answer about what your door actually needs.
Q: Can I replace just one spring if only one breaks? A: Technically yes, but most professionals recommend replacing both springs at the same time. Since both springs age at the same rate, if one has broken, the other is likely close behind. and you'll save on labor by doing both at once.
Q: How do I know if I have torsion or extension springs? A: Look above your garage door when it's closed. If you see a single horizontal spring (or two springs side by side) mounted on a metal bar above the door, those are torsion springs. If you see springs running along the horizontal tracks on either side of the door, those are extension springs.
Q: Is it safe to use my garage door if a spring is broken? A: No. Operating your garage door with a broken spring puts extreme stress on the opener motor and can cause the door to fall unexpectedly. Disconnect the opener and leave the door in the closed position until a technician can make the repair.
