Garage Door Repair in Candia, NH: What's Wrong and What to Do About It
2026-04-08 7 min read
If you live along one of Candia's back roads. tucked into the wooded hills off Route 27 or out toward East Candia. your garage door is probably the hardest-working mechanical system on your property. It opens and closes multiple times a day, through January lows that can dip into the teens and mud-season freeze-thaw cycles that are tough on just about everything.
When something goes wrong, it rarely picks a convenient time. This guide walks you through the most common garage door problems Candia homeowners actually deal with, what's causing them, and when you can fix it yourself versus when you should call a professional.
The Most Common Garage Door Problems in Candia
The Door Won't Open or Close
This is the call we get most often. The cause is usually one of three things: a broken spring, a dead opener, or a sensor problem. If you hear a loud bang coming from the garage and the door suddenly won't move, a broken torsion spring is almost certainly the culprit. Don't try to operate the door manually. a door with a broken spring is extremely heavy and can injure you. This is a job for a professional, full stop.
If the opener hums or clicks but the door doesn't move, the spring may be intact but the opener's drive mechanism or motor capacitor may have failed. If nothing happens at all, check your circuit breaker first. power surges during NH ice storms can trip breakers.
Sensor issues are common after a Candia winter. The photo-eye sensors mounted near the floor get bumped by snow shovels, ice melt residue, or shifting floors. Clean the lenses with a dry cloth and make sure both sensors are aligned (most units show a solid indicator light when aligned). This fixes the problem more often than you'd think.
The Door is Loud, Grinding, or Jerky
A grinding noise usually points to worn rollers or a lack of lubrication. Metal rollers last about 10,000 cycles and they deteriorate faster in cold climates where metal contracts and lubricants thicken. Nylon rollers are quieter and need less maintenance. they're worth the upgrade if you're replacing them anyway.
Jerky movement, where the door hesitates or stutters on the way up, often means the tracks are dirty, bent, or slightly out of alignment. Candia's temperature swings. we're talking 80°F summer days down to single digits in January. cause metal tracks to expand and contract over the years. Inspect the tracks visually for dents or gaps at the seams. Minor dents can sometimes be tapped out with a rubber mallet, but bent tracks usually need professional replacement to avoid long-term wear on your panels.
For regular squeaks and minor stiffness, proper bearing lubrication with a silicone or lithium-based spray goes a long way. Avoid WD-40 on springs and hinges. it attracts dirt and dries out too fast in NH winters.
Panels Are Damaged
Ice damming is a real problem on the older colonial and cape-style homes common throughout Candia. When water backs up under roofing, it can drip and refreeze on the garage door panels below the eave line. Repeated freeze-thaw cycles crack paint, warp steel, and eventually compromise panel integrity.
Single panel replacement is possible if your door model is still available. a good reason to note your door's brand and model number now, while it's not an emergency. If multiple panels are damaged, a full door replacement often makes more financial sense than piecing together individual sections.

The Door Reverses Before Closing
If your door starts to close and then immediately reverses, the most common causes are:
- Misaligned sensors. debris, spider webs, or ice near the sensor lens - Close-limit setting. the opener thinks the door has hit an obstruction before it reaches the floor - Weather seal bunching. a bottom seal stiffened by cold can create enough resistance to trigger the auto-reverse
For the limit setting, your opener's manual will walk you through adjusting the down-force. If you can't find the manual, the model number is usually printed on a label inside the motor housing.
DIY vs. Call a Pro: A Honest Assessment
Here's a straight answer: most Candia homeowners can handle cleaning sensors, lubricating hinges and rollers, tightening loose hardware, and replacing the bottom weather seal. These are safe, low-risk jobs.
Leave springs, cables, and track replacement to a professional. Torsion springs store an enormous amount of energy. enough to cause serious injury if released suddenly. The same goes for cables, which are under similar tension. If you're seeing frayed cables, rust on the spring, or the door is binding in the tracks, get in touch with us before the problem becomes a safety issue.
Seasonal Repair Patterns in Candia
Most emergency repairs in our area happen in three windows: late January through February (peak cold stress on springs and seals), mid-March through April (freeze-thaw cycles loosen hardware and swell wood components), and early November (doors that weren't serviced in fall start failing when temps drop). If you live out in Chester or Raymond and don't want to be stuck with a broken door on a January morning, a fall tune-up is worth scheduling before the cold sets in.
For homeowners who want to stay ahead of problems, preparing your door ahead of the warmer months is also a smart habit. summer humidity and heat create their own set of issues for NH doors.
Frequently Asked Questions
Q: How do I know if my garage door problem is the spring or the opener? A: Disconnect the opener by pulling the red emergency release cord, then try to lift the door manually. If it's extremely heavy and won't budge, the spring is likely broken. If it lifts smoothly by hand, the problem is with the opener, not the spring.
Q: My garage door is dented but still works fine. do I need to fix it? A: Cosmetically, it's your call. But dented panels can compromise the structural integrity of the door over time, especially in a climate like Candia's where moisture can get behind damaged paint and cause rust. If the dent is on a panel that's still available for your model, replacing just that section is usually affordable.
Q: How long should a garage door last in New Hampshire? A: A quality steel door with proper maintenance typically lasts 20,30 years in NH conditions. The hardware. springs, cables, rollers, and opener. will usually need attention well before the door itself does. Springs average 7,10 years in cold climates with frequent use.
