If your garage door suddenly refuses to open, or you hear a loud bang coming from the garage early in the morning, there's a good chance a spring has given out. It's one of the most common calls we get here at Lumberton Garage Doors. and in this part of Robeson County, it happens more often than homeowners expect. The reason isn't bad luck. It's the climate.
Lumberton sits in the southeastern North Carolina coastal plain, and the weather here is no joke for metal hardware. Summers are hot and muggy, with humidity regularly climbing to 78% or higher during August and September. Even in winter, relative humidity rarely drops below 72%. That persistent moisture in the air is one of the leading causes of spring failure.
Rust is the main culprit. When moisture in the air contacts your garage door springs, it begins oxidizing the metal surface. Over time, rust increases friction between the coils, forcing the spring to work harder every time the door moves. and that added stress accelerates wear. In a dry climate, a standard torsion spring might last 7,10 years. In a humid environment like ours, homeowners should realistically expect a shorter service life, especially without regular maintenance.
The seasonal temperature swings don't help either. When metal heats up and contracts repeatedly, microscopic cracks form inside the coil structure. Those cracks allow moisture to seep even deeper into the spring, worsening corrosion from the inside out. The stretch from a cold January night (lows around 36°F) to a July afternoon topping 89°F represents a real mechanical stress cycle for your springs, repeated hundreds of times over years of use.
Springs rarely fail without giving some signal first. The problem is most homeowners don't know what to look for. Here's what to watch:
- The door feels unusually heavy when you try to lift it manually. Springs counterbalance the door's weight. when they wear, you feel it. - Squeaking or grinding sounds during operation are often the first audible sign that friction is building up between corroded coils. - A crooked or uneven door as it opens can indicate one spring on a two-spring system has more wear than the other. - Visible rust or gaps in the coil are clear indicators the spring is approaching the end of its life.
If you notice any of these, it's worth scheduling a service call sooner rather than later. Catching a worn spring before it snaps outright means you control the timing. not the spring.
When one spring breaks, many homeowners ask to replace only the broken one. It seems logical, but it's actually a false economy. On a two-spring system, both springs have been running the same number of cycles under the same conditions. Replacing just one puts an older, fatigued spring alongside a fresh one. and that imbalance accelerates wear on both the new spring and connected components like cables and rollers. In most cases, the second spring follows within months.
Replacing both at the same time costs less than two separate service calls, and it gives you balanced performance from a matched set. If you want to go further, ask about high-cycle springs or galvanized steel springs. The zinc coating on galvanized springs acts as a protective barrier against humidity-driven corrosion. a meaningful upgrade for our climate. They cost more upfront, but the per-year cost is typically lower once you account for the extended lifespan. You can also learn more about related hardware wear in our guide on roller replacement, since springs and rollers often age together.
You don't need to be mechanically inclined to add years to your springs. A few straightforward habits make a real difference:
Apply a silicone-based lubricant (not WD-40, which attracts dust) to the springs every three months. In Lumberton's humidity, more frequent application. especially heading into summer. is worthwhile. This reduces friction, displaces moisture, and slows rust formation significantly.
Many homes in the Lumberton area, particularly the ranch-style and single-story brick homes common in neighborhoods off Kahn Drive and around the Roberts Avenue corridor, have attached garages that trap humidity. If your garage feels damp in summer, a simple exhaust vent or even leaving the door cracked periodically helps reduce the moisture level that accelerates corrosion.
Take 60 seconds every spring and fall to look at your springs. Look for rust discoloration, visible gaps between coils, or any section that appears thinner or stretched. If something looks off, call a professional. don't try to adjust spring tension yourself. Springs operate under extreme stored tension and can cause serious injury if handled without the right tools and training.
If your door is completely stuck, won't open more than a few inches, or you've heard the loud crack of a spring breaking, stop using the opener immediately. Continuing to run the motor against a broken spring can burn out the opener and damage cables. This is a repair that genuinely needs a professional. spring replacement requires precise tension calibration to restore proper door balance.

For homeowners in Fairmont, Red Springs, and Pembroke, the same humidity conditions apply throughout Robeson County. spring maintenance should be on everyone's annual home care checklist regardless of which side of the county you're on.
How long do garage door springs typically last in Lumberton's climate? Standard torsion springs are rated for about 10,000 cycles, which translates to roughly 7,10 years with average use. In Lumberton's persistent humidity, that lifespan can be noticeably shorter without regular lubrication and maintenance. Galvanized or high-cycle springs are worth the investment if you're replacing springs and plan to stay in your home long-term.
Can I replace a garage door spring myself? It's strongly not recommended. Garage door springs store a significant amount of mechanical energy under tension. An improperly handled spring can snap with enough force to cause serious injury. This is one garage repair that should always be handled by a trained technician with the proper tools.
Do I really need to replace both springs if only one broke? In almost every case, yes. Both springs have experienced the same wear over the same number of cycles. Replacing only the broken one creates uneven tension, puts excessive stress on the new spring, and typically leads to a second service call within months. Replacing both at once is safer, more cost-effective, and gives you balanced performance.
