Most homeowners in Murphy don't think about their garage door until something goes wrong. That's understandable. it opens, it closes, it does its job. But the climate here in Cherokee County is genuinely tough on garage door systems. Between winter temperatures that can drop to 29°F in January, summer humidity hovering around 76,80% all year long, and nearly 40 inches of annual rainfall spread across roughly 181 wet days, your door's hardware is working against real environmental pressure every single day.
The good news is that most major garage door failures are preventable. A simple seasonal routine. a few minutes four times a year plus a few monthly checks. can extend the life of your door significantly and catch small problems before they become expensive ones.
Here's what to do and when.
Murphy sits at around 1,600 feet in the southern Appalachians. The town sees genuine four-season weather: cold, sometimes icy winters; warm and humid summers; and spring and fall seasons that bring significant rainfall. That humidity is constant. even in the cooler months. For garage doors, that means metal components are exposed to moisture year-round, wood doors and frames are prone to swelling and warping, and weatherstripping faces a constant battle against temperature cycling.
Homes in the areas closer to downtown Murphy. including older craftsman-style houses and the mid-century ranches common in established neighborhoods. often have original or aging garage door hardware that hasn't been updated in decades. If your home falls into that category, these maintenance steps matter even more.
Once a month, take five minutes to run through this quick check. You don't need any tools.
- Watch the door move. Open and close it fully and observe. Does it move smoothly, or does it jerk, hesitate, or shudder? - Listen carefully. Grinding, squeaking, or scraping are early warning signs. Catching them early means lubrication or a minor adjustment. not an emergency call. For a deeper guide on what specific sounds mean, check out our post on decoding noisy garage doors for Murphy homeowners. - Check the tracks visually. Look for debris, leaves, or anything blocking the path. Murphy homeowners with wooded lots. especially those near the Hiwassee River area. should pay attention here. Leaves and pine needles find their way into tracks more than you'd expect. - Test the auto-reverse safety feature. Place a 2x4 flat on the ground in the door's path and close the door. It should reverse immediately upon contact. If it doesn't, don't use the door until the sensor or opener is serviced.
Spring is the most important maintenance window of the year in Murphy. After months of temperature cycling. including potential ice events, cold nights, and the freeze-thaw pattern Cherokee County regularly sees from December through March. there's wear you need to find before it becomes a problem in the busy months ahead.
- Inspect all hardware. Look for frayed cables, loose hinge bolts, and bent tracks. Garage doors vibrate with every cycle, and that vibration gradually loosens hardware over a winter of cold-contraction and expansion. - Check weatherstripping. The bottom seal and side weatherstripping take a beating from frost and ice. If you see cracking, gaps, or sections that no longer make full contact with the floor or frame, replace them. Gaps let in moisture, drafts, and the occasional pest. a real concern in wooded mountain areas. - Lubricate all moving parts. Use a silicone-based or lithium-based spray lubricant. not WD-40, which is a degreaser, not a lubricant, and will actually dry out your components faster. Apply to hinges, roller stems and bearings, and springs. Do not spray lubricant directly on the track surface itself. - Inspect the springs. Look for visible gaps in the coils of a torsion spring, or any sign of rust or uneven coil spacing. If anything looks off, call a professional. Spring tension adjustment and replacement is not a safe DIY job.
Murphy summers are warm and humid, with July averaging around 84°F and afternoon thunderstorms a regular occurrence. Heat causes metal expansion, which can tighten the fit of rollers in tracks and put stress on the opener motor.
- Re-lubricate if you notice new noise. Heat increases friction on moving parts. If your door starts squeaking in July, it likely just needs fresh lubricant. - Clean and realign safety sensors. Bright summer sun can interfere with photo-eye sensors if they're positioned in a way that catches direct light. Wipe the lenses clean with a soft cloth and confirm both sensors show a steady LED light, not a blinking one. - Wipe down door panels. For steel doors, summer heat and UV exposure can begin to fade or degrade the finish. For wood doors. common on older Murphy homes and cabin-style properties. check for moisture absorption, swelling, or warping. A swollen wood door can bind against the frame and put stress on the opener. - Test opener batteries. If you have a smart opener or keypad, confirm the backup battery is functional, especially before storm season picks up.
Fall in Murphy is beautiful. peak foliage usually hits in late October. but it's also the window to prepare your garage door system for winter before temperatures drop. Doing this now is much easier than dealing with a frozen or seized component in January.
- Tighten all hardware. Go over hinges, brackets, roller brackets, and track supports with the appropriate wrench. Tighten anything that's worked loose over the summer. - Check door balance. Disconnect the opener using the red emergency release cord. Lift the door manually to about waist height and let go. A properly balanced door should stay in place. If it falls down or shoots up, the spring tension is off. call Murphy Garage Doors for an adjustment before winter. - Inspect and replace weatherstripping if needed. This is the second critical weatherstripping window of the year. A tight seal heading into winter keeps out cold air, moisture, and critters looking for warm shelter. - Replace remote batteries proactively. Cold weather drains batteries faster than warm conditions. Swap them out in fall and you'll avoid the experience of standing in the cold with an unresponsive remote.

Murphy winters are cold enough to create real garage door problems. Ice events, overnight temperatures in the low 30s, and the freeze-thaw cycle all stress your system.
- Never force a door that's frozen to the ground. If the bottom seal has frozen to the concrete, forcing the opener risks burning out the motor or breaking components. Use a heat gun or hair dryer to gently thaw the seal before operating the door. - Keep tracks clear of ice and snow. Ice in the track can cause rollers to bind or jump the track entirely. After significant winter weather, clear the area before operating the door. - Lubricate with a cold-weather-appropriate spray. Standard lubricants can thicken in cold temperatures. Use a product rated for low-temperature use during winter months.
This checklist covers what homeowners can reasonably handle themselves. But some things should always go to a professional:
- Any spring adjustment or replacement. springs are under high tension and dangerous to handle without proper training and tools. - Cable repairs. frayed or snapped cables require professional attention. - Track realignment. if a track is visibly bent or the door moves unevenly despite clear tracks, a tech needs to assess it. - Opener issues beyond battery replacement. circuit board failures, motor problems, and sensor wiring should be handled by someone who knows the system.

Given Murphy's year-round humidity and significant seasonal temperature swings, lubricating moving parts every three to four months is a smart routine. more frequently than the standard recommendation for drier climates. At minimum, do a full lubrication in spring after the cold season and again in early fall before temperatures drop.
No. WD-40 is primarily a water displacer and degreaser, not a lasting lubricant. Using it on garage door components can actually dry them out faster and attract dirt and grime. Use a silicone-based spray or white lithium grease formulated for garage door systems instead.
Disconnect the automatic opener using the red emergency release cord. Manually lift the door to about waist height. roughly halfway up. and release it. If the door stays in place, the balance is good. If it falls toward the ground or rises toward the ceiling, the spring tension needs adjustment. That adjustment should be made by a professional, not a homeowner, as springs are under significant tension.
