Most people don't think about their garage door until something breaks. By then, you're stuck outside in the New London cold or heat, frustrated, and wondering how much this will cost. Here's the truth: before you panic and call for same-day service, there are several things you can troubleshoot yourself. Some of the most common problems are fixable in minutes.
Your garage door won't open or close for one of a handful of reasons. Before assuming the worst, walk through these steps. See our guide on security lighting: protecting your family.
First, check your remote batteries. This sounds obvious, but dead batteries account for roughly 20 percent of "broken door" calls. Replace them with fresh ones and try again from different distances. If the wall button works but the remote doesn't, you've found your culprit. If neither works, move to step two.
Next, inspect the photo eye sensors mounted on both sides of the garage door frame, about 6 inches up from the ground. These infrared safety sensors block the door if anything crosses the beam. Dust, spider webs, or misalignment will trigger a malfunction. Wipe both lenses clean with a soft cloth and ensure they're pointing directly at each other. Many stuck doors are actually just dirty sensors. Read about garage door repair in new london: why your door won.
Check the track for obvious obstructions. Leaves, gravel, or a child's toy can jam the rollers. Clear the tracks by hand if you can see something blocking it. Do not attempt to force the door open if it's stuck.
If the basics don't help, you're likely facing a mechanical issue. Springs fail, cables snap, and openers wear out. This is where professional diagnosis becomes critical because working on these components incorrectly can cause serious injury.
Garage door springs are under tremendous tension. A single broken spring can cause the door to fall or refuse to lift at all. Springs typically last between 7 and 9 years depending on use. If your door is older than that and suddenly won't open, springs are the prime suspect. Do not attempt to replace them yourself. We've seen hand injuries that could have been prevented.
The opener motor might be the issue too. Listen for noise when you press the button. If the opener runs but the door doesn't move, the problem is likely a broken gear inside the motor or a snapped cable. Both require professional replacement.

One of the biggest fears around garage door repair is the estimate. What will this actually cost? The answer depends entirely on what's broken.
A broken spring replacement runs between $200 and $400. Cable replacement is similar. A new garage door opener motor ranges from $300 to $600 depending on the type. If you need help understanding pricing before calling, our detailed post on [garage door cost and pricing in New London] (/blog/garage-door-cost-pricing-new-london-ct) breaks down typical expenses.
The good news is that most repairs are not emergencies if you act quickly. A door that won't open or close should be inspected within a day or two, but you're not in danger. The exception is a door that's partially closed or hanging unevenly. That indicates a spring or cable failure and should be addressed immediately to prevent the door from falling.
When you call for an estimate, ask about same-day availability. New London Garage Doors offers quick inspections so you know exactly what you're paying before we start work. No surprises, no hidden fees.
The best repair is the one you never need. Seasonal maintenance catches small problems before they become expensive ones. We recommend checking your springs, cables, and rollers twice a year, especially before winter when cold temperatures put extra stress on metal components.
New London winters are particularly hard on garage door springs, as we've documented in our [guide to spring failure in winter] (/blog/garage-door-spring-failure-winter-new-london). Salt air from Long Island Sound also accelerates rust and corrosion. If you live near the coast, inspect your door more frequently.

A broken garage door is frustrating, but it doesn't have to be expensive or complicated. Many issues are preventable with basic care. When repair is necessary, the sooner you call, the sooner you're back to normal.
How do I know if my garage door spring is broken? Your door will feel extremely heavy or won't open at all. You may hear a loud bang before it stops working. Do not attempt to lift it manually. Springs are under extreme tension and can cause serious injury if mishandled.
Can I repair my garage door myself? Minor fixes like cleaning sensors or replacing remote batteries are safe. Never attempt to repair springs, cables, motors, or openers yourself. These components carry extreme tension or electrical hazards that require professional training.
How long does a garage door repair typically take? Most repairs take 1 to 2 hours. A spring replacement might take slightly longer. We offer same-day service across New London and surrounding areas when scheduling allows.
What's the difference between repair and replacement? Repair fixes a specific broken component like a spring or cable. Replacement means installing an entirely new door. Our team can advise which makes sense based on your door's age and condition.
