If you've ever walked into your garage on a January morning in Loudon only to find the door frozen to the ground or refusing to budge, you already know what we're talking about. This isn't bad luck. it's predictable. Loudon sits in Merrimack County with a humid continental climate that delivers genuine four-season punishment to anything mechanical that lives outside. Understanding exactly why that punishment happens is the first step to keeping your garage door running reliably all year long.
Loudon winters are no joke. January averages a high of just 27.7°F and a low of 14.9°F, and the town accumulates nearly 31 inches of snow across the season. But raw cold is only part of the story. It's the freeze-thaw cycle. temperatures swinging below freezing overnight and then partially thawing during the day. that does the most damage over time.
Every time that cycle runs, metal components in your garage door system expand and contract. Tracks, hinges, springs, and cable drums all go through this stress repeatedly from October through April. Check our services page to see the full range of repairs that commonly result from this kind of seasonal wear.
When wet snow or rain pools along the base of your garage door and the temperature drops overnight, the rubber bottom seal freezes directly to the concrete floor. It happens to homeowners across Loudon and the nearby town of Concord every winter. The instinct is to force the door open with the opener. resist that. Forcing a frozen door tears the weatherseal, which then lets cold air, moisture, and rodents in all winter long. Instead, use warm water or a heat gun at a safe distance to melt the ice at the base before hitting the opener button.
Standard garage door lubricants can thicken, stiffen, or harden entirely when temperatures drop below freezing. Once that happens, the product that was supposed to reduce friction is now acting like glue on your rollers, hinges, and bearings. The door drags, the opener motor strains, and components wear out faster than they should. The fix is simple but specific: silicone-based lubricant resists freezing far better than petroleum-based grease or WD-40. Apply it to tracks, rollers, hinges, and the torsion spring coil each fall before the first hard freeze.
Cold causes metal to contract. Every metal part. the tracks, hinges, and screws. shrinks when chilled, and slight contraction of the tracks can cause minor misalignment that leads to rollers binding and the door sticking or moving unevenly. If your door has started squeaking, grinding, or moving in a jerky motion during cold weather, track alignment is worth having a professional check before the problem compounds.
This is where Loudon homeowners need to pay close attention. Torsion springs are already under enormous tension at room temperature. When the metal gets cold and contracts, the springs become more brittle. and more susceptible to snapping. A broken spring often happens with a loud, sudden bang, typically in the dead of winter when the metal is at its coldest and most stressed.
If your spring breaks, stop using the door immediately. The opener is suddenly forced to handle the full dead weight of the door. which for a standard residential door can be 150,300 pounds. and that will destroy the motor quickly. This is not a DIY repair. Springs store extreme tension and can cause serious injury if handled without the right tools and training. Reach out to schedule a repair before a worn spring becomes a broken one.
You don't always get the loud bang as a warning. Watch for these signs:
- The door feels unusually heavy when you try to lift it manually, The door moves unevenly or tilts to one side when opening, You hear squeaking or grinding that lubrication doesn't fix, The opener sounds like it's straining harder than usual, You can see visible gaps or rust in the spring coils
If the door drifts down or up when you stop it halfway open, the spring tension is off and needs professional adjustment.
The best time to deal with these problems is before they happen. Here's a straightforward fall checklist for Loudon homeowners:
1. Lubricate everything with silicone-based lubricant. springs, rollers, hinges, and tracks. 2. Inspect the bottom weatherseal for cracks or brittleness and replace it if it's stiff. 3. Test the door balance by disconnecting the opener and lifting the door manually to waist height. It should stay put without drifting. 4. Clear snow from the base after every storm so meltwater doesn't pool and refreeze overnight. 5. Check opener batteries. cold temperatures drain them faster than you'd expect. 6. Schedule a professional tune-up every fall if your door is more than five years old.
Many of the calls Loudon Garage Doors receives in January and February are entirely preventable with a fall maintenance visit. A tune-up costs a fraction of what an emergency broken-spring call runs in the middle of a snowstorm.

Loudon has a mix of housing stock. from renovated New England farmhouses and colonial-style homes built decades ago to newer developments. Many of the older attached garages were built without insulation, which means the temperature inside the garage tracks very closely with the outdoor air. An insulated garage door stabilizes the interior temperature, reduces metal contraction, and keeps lubricants from freezing. If your current door is aging anyway, it's worth factoring insulation rating into the replacement decision.
Cold causes metal components to contract and lubricants to thicken, both of which increase friction and resistance in the door system. Springs also become more brittle in sub-zero temperatures. The door isn't failing randomly. it's reacting predictably to Loudon's winter climate.
No. A loud bang almost always means a spring has broken. Stop using the door immediately and contact a technician. operating it with a broken spring can destroy the opener motor and risks the door falling unexpectedly.
At minimum, lubricate all moving parts. springs, rollers, hinges, and tracks. once in the fall before freezing temperatures arrive, and again in the spring. If you notice grinding or sticking during winter, a mid-season application of silicone-based lubricant can help.
