Why Garage Door Springs Break in Apex (And How to Stay Ahead of It)
2026-03-20 7 min read
If you've ever walked into your garage on a cold January morning and heard a loud bang. then found your door completely unresponsive. you already know what a broken torsion spring feels like. It's one of the most common service calls we receive at Apex Garage Doors, and it's not random. The way Apex's climate behaves throughout the year puts specific and predictable stress on your garage door hardware. Understanding that stress is the first step toward avoiding an inconvenient and potentially costly surprise.
How Apex's Climate Punishes Garage Door Springs
Apex sits squarely in the humid subtropical zone, which means the area experiences a wide temperature range. from lows hovering around freezing in January to summer highs pushing close to 90°F. That swing alone is hard on metal components, but it's the combination of heat, cold, and persistent moisture that really shortens spring life here.
Garage door springs are made of tightly wound steel. When winter temperatures drop, that steel contracts and becomes more brittle, making springs more susceptible to snapping under tension. Apex winters are relatively short but they do dip to freezing, and the area sees some snowfall from January through March. enough to matter. The real compounding factor, though, is humidity. With monthly average humidity levels consistently in the 71,76% range year-round, moisture is always in the air inside your garage.
Rust is a major enemy of garage door springs. Moisture in the air, especially in unconditioned garages, causes corrosion to develop on the spring's surface. Rust increases friction between the coils, forcing the spring to work harder every time the door moves, and that added stress accelerates wear significantly.
Spring and fall present their own challenge. When March temperatures swing from mild afternoons down to near-freezing nights, the repeated thermal cycling silently weakens components. Torsion springs typically fail first in these cycles, often right when homeowners start opening the garage more frequently for spring yard work and projects. If you're in neighborhoods like Haddon Hall, Scotts Mill, or the newer Friendship Station area where many homes have two and three-car garages with daily heavy use, your springs are accumulating cycles fast.
How Long Should Your Springs Last?
Most standard residential torsion springs are rated for around 10,000 cycles. one cycle being a single open-and-close sequence. If you use your garage door four times per day (a reasonable number for a family using it as a primary entrance), that works out to roughly seven to nine years of service life. High-cycle springs rated for 25,000+ cycles are available and worth the investment for busy households.
Here's what speeds up that wear in Apex specifically:
- High humidity causing surface rust on the coil - Freeze-thaw cycling from November through March creating cumulative metal fatigue - Heavier garage doors. the large craftsman-style and colonial homes common throughout Apex often feature oversized double doors, which put more load on springs - Improper installation. springs sized for a door that's lighter than yours will wear out much faster

Warning Signs Your Springs Are Failing
Don't wait for the loud bang. These are the signs worth paying attention to:
The Door Feels Unusually Heavy
Garage door springs counterbalance the weight of the door. a standard residential door can weigh anywhere from 130 to over 400 pounds. If the springs are weakening, the opener has to work harder to compensate, and you may notice the door moving slower or straining. Disconnect the opener and manually lift the door halfway. A properly balanced door stays put; if it drops or shoots upward, the spring tension needs attention.
Gaps in the Coils
Look at the torsion spring mounted above your door (don't touch it. springs carry significant tension). A visible gap between coils means the spring has already lost tension and failure is imminent.
Jerky or Uneven Movement
If the door jerks, stops mid-travel, or one side appears lower than the other while operating, you may have one spring already weakened or broken in a two-spring system.
Squeaking, Grinding, or Popping Sounds
Springs that make excessive noise during operation are telling you something. A sudden loud pop from the garage. even when the door isn't actively in use. is often the sound of a spring snapping.
What to Do When a Spring Breaks
The short answer: call a professional and don't try to operate the door manually. Springs hold tremendous tension, and attempting a DIY replacement increases the risk of serious injury. Beyond safety, spring replacement requires mathematically precise calibration. if tension is too high, the door flies open and can burn out the opener's logic board; too low, and the motor strips its internal gears within weeks.
When one spring breaks, it's strongly recommended to replace both at the same time. Springs on the same door wear at similar rates, and one spring often fails within six months of the other. Replacing both together saves money and prevents a second service call.

And if you're ready to have someone take a look, contact Apex Garage Doors to schedule an inspection before a minor wear issue turns into an emergency repair.
Extending Spring Life in a Humid Climate
A few practical habits make a real difference here:
1. Lubricate twice a year. Use a silicone-based spray or white lithium grease, not WD-40. Apply a light coat along the full length of the torsion spring. This reduces friction and creates a barrier against rust from humidity. Do it once in fall before temperatures drop, and again in spring. 2. Schedule an annual inspection. Ideally in early fall before the cold-weather brittle period. A technician can spot metal fatigue and fraying cables before they become failures. 3. Consider upgrading to galvanized or oil-tempered springs. These are specifically designed to resist corrosion and hold up better in humid climates like ours. 4. Don't ignore the door balance test. Do this simple check twice a year. Disconnect the opener, lift the door manually to about waist height, and let go. If it doesn't stay put, the springs need adjustment.
Homeowners in nearby Cary and Morrisville deal with the same climate conditions, and the same maintenance habits apply. The chemistry between steel hardware and a humid subtropical environment doesn't change at the town line.
Frequently Asked Questions
How do I know if my garage door spring is broken versus some other problem? The most obvious sign is a visible gap in the coil of the torsion spring above the door, or the spring appearing to be in two pieces. The door will also feel extremely heavy or won't open at all when the spring is broken. If the opener runs but the door barely moves or only lifts an inch before stopping, a broken spring is the likely cause.
Is it safe to use my garage door with a broken spring? No. Operating a garage door with a broken spring puts enormous stress on the opener motor, cables, and other hardware. It can cause secondary failures and poses a safety risk. a door without proper spring tension can fall unexpectedly. Keep the door closed and call a technician.
Should I replace both springs even if only one broke? Yes, in almost all cases. Both springs wear at similar rates, and if one has failed, the other is likely near the end of its life too. Replacing both at the same time costs less than two separate service calls and prevents being stranded again in a few months.
