If you've lived in Kendalia for more than a summer or two, you know the weather doesn't play nice with anything metal left outside. The same climate that makes the Hill Country beautiful. the temperature swings, the spring thunderstorms rolling through from the west, the dry heat that can push into the mid-90s by August. quietly does a number on your garage door springs year after year. Most homeowners don't think about springs until one snaps, usually on a Tuesday morning when they're already running late.
Understanding why springs wear out faster here than in milder parts of the country can save you from that exact scenario.
Kendalia sits at roughly 1,388 feet in Kendall County, and the area experiences the full range of Central Texas weather. Summers push into the low 90s regularly, with the heat index climbing even higher during humid stretches. Winters bring periodic cold fronts that can drop overnight lows into the 30s. sometimes well below that. That's not an unusual swing; it's a 50-to-60-degree difference between a January night and an August afternoon.
For your garage door springs, those swings are a constant mechanical stress test. Torsion springs. the horizontal coiled springs mounted above your door. are made of steel. As temperatures climb, metal expands and becomes more pliable; as it cools, it contracts and stiffens. Repeated over thousands of cycles, this expansion and contraction gradually reduces the structural integrity of the spring and places added strain on the opener as it works harder to move the door.
Rust compounds the problem significantly. When humidity moves in. especially during spring storm season. moisture settles on the metal coils. That oxidation doesn't just look bad; it increases friction between the coils and weakens the steel itself. A spring that might last 10 years in a dry climate can fail noticeably sooner in conditions like ours, where heat, humidity, and cold fronts all take turns.
Homeowners out toward Boerne and Comfort deal with the same issues. The limestone-rich soil and the shallow bedrock common across Kendall County can also cause subtle foundation and garage floor shifts over time, which changes how evenly a door sits in its frame and puts uneven tension on springs.
Spring failure rarely comes completely out of nowhere. Here's what to look for before you end up with a door that won't open:
- Rust or visible corrosion on the coils. look for discoloration or flaking along the spring body - Gaps between coils or uneven spacing, which points to metal fatigue - Grinding or creaking sounds when the door operates, especially first thing in the morning when temperatures have been cooler overnight - The door moves unevenly. one side rising or dropping faster than the other - The opener strains audibly and the door feels heavier than usual when lifted manually
To test balance yourself: disconnect the opener using the manual release cord, then lift the door halfway by hand. A properly balanced door stays put. If it drops or shoots upward, the spring tension is off and the system needs a professional look. You can learn more about safely using the manual release in our guide to manual release mechanisms.
Never attempt to adjust or replace springs yourself. They're under extreme tension and require specialized tools and training. This is one of the few garage door jobs that genuinely warrants a call before you touch anything.
Regular lubrication is the single most effective thing a homeowner can do. Use a lithium-based garage door lubricant. not WD-40, which strips existing lubrication and attracts dust. Apply it to the spring coils, hinges, and rollers at least twice a year: once before summer heat peaks, and again heading into fall before the first cold fronts arrive. It takes about ten minutes.
Keep the area around your springs clear and dry. If your garage door faces west or south and gets direct afternoon sun, that door surface heats up faster than the surrounding air, accelerating wear on everything it's attached to.
When springs do need replacing, ask about high-cycle torsion springs with powder-coated or galvanized steel construction. These resist rust better and are rated for significantly more open-close cycles than the builder-grade springs that come standard on most doors. On a busy household where the garage is the main entry point, that upgrade makes a real difference over a 5,10 year period.
Our full checklist for seasonal preparation. including spring inspection steps. is covered in detail in our post on preparing your garage door for winter. Many of those same tips apply coming out of summer as well.
If your springs are showing any of the signs above, or if you haven't had a professional look at the system in the last few years, schedule an inspection with us before the next heat wave or cold front makes the decision for you.
How long should garage door springs last in Kendalia? Under ideal conditions, standard torsion springs are rated for around 10,000 cycles. roughly 7 to 10 years for an average household. In Central Texas, where heat, humidity, and temperature swings accelerate metal fatigue and corrosion, springs often reach the end of their effective life sooner. High-cycle springs with rust-resistant coatings can significantly extend that lifespan.
Can I still use my garage door if a spring is worn but hasn't broken? Technically yes, but it's not a good idea. A weakened spring puts extra strain on the opener motor, cables, and hardware. and can fail suddenly without warning. It's much safer and cheaper to replace a worn spring on your schedule than to deal with an emergency when the door won't open or close.
Why did both of my springs break at the same time? On two-spring systems, both springs were typically installed at the same time and have experienced the same wear. When one fails, the other is usually close behind. Most professionals recommend replacing both simultaneously to avoid a second service call and to keep tension balanced across the door.
