If you've lived in Pleasant Hill for a few years, you already know how dramatic the temperature swings can be. Summers push into the high 80s. sometimes topping 97°F. while January nights can dip into the low 40s. That 50-degree annual range might not seem like much, but for the tightly wound steel springs above your garage door, it adds up to serious wear every single year.
This is one of the most overlooked reasons why homeowners in Pleasant Hill, Concord, and throughout Contra Costa County end up calling for emergency spring replacement. The failure doesn't happen overnight. It's the slow result of metal contracting in cool, wet winters and expanding again under the summer heat. cycle after cycle, year after year.
Pleasant Hill has a Mediterranean climate with hot, dry summers and mild, rainy winters, with most rainfall concentrated between December and March. That seasonal back-and-forth does something specific to steel: it causes the coils to expand when temperatures rise and contract when they drop. Each swing adds microscopic stress to the metal that accumulates over time.
In the dry summer months. when Pleasant Hill receives almost no rainfall from June through September. lubricants on your springs can dry out faster than you'd expect. Without adequate lubrication, friction between coils increases sharply, which accelerates wear and shortens the lifespan of even a quality spring. Add in the roughly 310 sunny days a year this area sees, and the UV exposure on an uninsulated garage adds another layer of stress on rubber seals, weather stripping, and internal components.
Winter brings the opposite problem. Cool, damp air. humidity hits around 77% in January. creates conditions where surface rust can start forming on unprotected spring coils. Even light corrosion creates microscopic pits in the steel that concentrate stress and accelerate cracking over time.
Most springs don't fail without giving some warning first. Here's what to watch for:
- Squeaking or grinding during operation. Often means the springs are dry and need lubrication. Left unaddressed, this friction accelerates wear considerably. - The door feels heavier than usual. If you disconnect the opener and try lifting the door manually, it should rise smoothly. If it feels like you're lifting dead weight, the spring tension is likely compromised. - Visible gaps in the spring coil. A torsion spring above your door should look like a continuous, tightly wound coil. A gap or separation means it has already broken. - The door moves unevenly. One side rising faster than the other often indicates uneven spring tension, which strains your opener and cables. - A loud bang from the garage. One of the most common calls we hear: homeowners report hearing what sounded like a gunshot from the garage. That's almost always a torsion spring letting go.
If you're noticing any of these signs, check out our frequently asked questions page for quick guidance, or contact our team to schedule an inspection before the spring fails completely.
Garage door springs operate under enormous tension. a standard two-car door spring carries the weight of a 150,250 lb door. When a spring breaks, it can create a loud bang, send hardware flying, or leave the door completely inoperable. Attempting a replacement without the right tools and training is genuinely dangerous, and forcing the opener to compensate for a broken spring can damage the motor and cables, turning a $200 repair into a much bigger job.
This is one area where calling a professional isn't just convenient. it's the right call for your safety and your wallet.
Prevention is straightforward. Twice a year. ideally in the fall before the rains hit and again in late spring before summer heat peaks. do a quick inspection:
1. Lubricate the springs with a silicone-based garage door spray (not WD-40, which dries out quickly). Apply it to the coils and wipe off the excess. 2. Check the balance by disconnecting the opener and manually lifting the door halfway. It should hold its position on its own. If it drops or shoots upward, the spring tension is off. 3. Look for rust or discoloration along the coil surface, especially after a wet winter. 4. Listen during operation. smooth and quiet is good; grinding, squealing, or banging means something needs attention.
For homes in older Pleasant Hill neighborhoods like Gregory Gardens or Poets Corner. where many garage systems were installed in the 1970s and 80s. it's especially worth having a professional do a full inspection. Springs rated for 10,000 cycles can wear out in seven to ten years under regular use, and many of those systems are well past their original lifespan.

Q: How long do garage door springs typically last in Pleasant Hill? A: Most standard torsion springs are rated for about 10,000 open-and-close cycles. For a household using the garage 4,6 times daily, that works out to roughly 7,10 years. Pleasant Hill's temperature swings and dry summers can shorten that window, especially if the springs aren't lubricated regularly.
Q: Can I still use my garage door if one spring is broken? A: Technically the door may still move with one spring intact, but we strongly advise against it. The opener is forced to carry far more weight than it was designed for, which risks burning out the motor. The door is also unbalanced and potentially dangerous. Call for repair the same day if possible.
Q: Should I replace both springs at the same time, even if only one broke? A: Yes, almost always. Both springs have the same age and wear history. If one has failed, the other is typically close behind. Replacing both together saves you a second service call and ensures your door is properly balanced going forward.
