The short answer: tighten and lubricate the hardware, replace worn weatherstripping, test the auto-reverse safety sensors, and have the spring tension checked before temperatures start swinging between warm afternoons and cold nights. That combination — not deep snow — is what actually stresses a garage door system along the Grand Strand.
Why Winter Here Is Different
Myrtle Beach doesn't get a hard winter in the way most of the country does, but the shoulder season between fall and winter does something specific to garage doors: it swings. Warm, humid days followed by cold nights cause metal hardware to expand and contract repeatedly, which loosens bolts, hinges, and track brackets over a few months. Add in the moisture that lingers around garages from heavy fall rain and pine needles piling up near thresholds, and you get the conditions for rust on springs, tracks, and rollers that often goes unnoticed until the door starts binding or squealing.
Every few winters, an ice storm pushes through and coats everything — including garage door tracks and exposed springs — in a thin layer of ice. A door that was already a little out of alignment or running on a weak spring can fail outright in that kind of cold snap, because cold metal is less forgiving and springs lose some tension as temperatures drop.
The Pre-Winter Checklist
1. Inspect and Replace Weatherstripping
The rubber seal along the bottom of the door and the vinyl stops along the sides keep out wind-driven rain and cold air. After a summer of UV exposure and humidity, this strip often cracks or flattens. Run your hand along it — if it's stiff, torn, or doesn't spring back, replace it. This is a simple DIY job and keeps both cold air and pests out of the garage.
2. Clear Pine Debris and Check Drainage
Pine needles and leaf litter tend to collect right at the base of the door and in the track channels. Left there, they trap moisture against the metal and accelerate rust. Sweep the area clean and make sure water isn't pooling at the threshold — standing water that freezes during a cold snap can glue the door to the slab.
3. Lubricate Moving Parts
Use a silicone-based garage door lubricant (not WD-40, which attracts grit) on the hinges, rollers, and springs. Humidity speeds up corrosion on exposed metal, so a light coat before winter protects against both rust and the stiffness that makes doors noisy on cold mornings.
4. Check Spring Tension
Springs lose a small amount of tension as temperatures drop, and a spring that was already near the end of its life cycle is more likely to snap in cold weather. Signs of a weakening spring include the door feeling heavier when lifted manually, visible gaps in the coils, or the opener straining and reversing unexpectedly. This isn't a DIY repair — springs are under heavy tension and should be handled by a trained technician.
5. Test the Auto-Reverse and Sensors
Cold mornings mean kids and pets are moving through the garage in low light. Place a block of wood in the door's path and confirm it reverses on contact. Also wipe down the photo-eye sensors near the floor — condensation and dust build up fast in humid climates and can cause false reversals or a door that won't close at all.
6. Plan for Power Outages
If storm remnants or an ice event knock out power, an opener with battery backup keeps you from being stuck manually hauling the door open. If your current opener doesn't have one, this is a reasonable time to upgrade before you actually need it.

Our technicians handle spring replacement and full garage door maintenance visits that cover exactly the checklist above — track alignment, hardware tightening, lubrication, and a safety sensor test — so you're not guessing whether your setup will hold up when temperatures drop. We also install battery backup openers for households that want a buffer against storm-related outages.
Whether you're in Myrtle Beach, North Myrtle Beach, Conway, Murrells Inlet, or anywhere else along the Grand Strand, a quick seasonal check now is cheaper and faster than an emergency call during a cold snap. Call Myrtle Beach Garage Door Works today to get your door ready for winter.
