Here's what most homeowners don't realize about garage door repair: half the time, the door isn't actually broken. It's stuck, misaligned, or simply out of power. Before you call for service, a few quick checks can save you money and frustration. This guide walks you through troubleshooting your garage door so you know whether you need professional help or just a minor adjustment.
Your garage door won't open or close? Start here. Check the power first. Walk to your garage door opener and confirm the unit is plugged in and the outlet has power. Test the outlet with another device if you're unsure. Next, look at your remote control. Replace the batteries. A dead battery is the most common reason a door won't respond to commands.
Now try the wall button inside your garage. If the wall button works but the remote doesn't, the remote batteries were likely the culprit. If neither works, you're looking at an opener issue or a safety sensor problem. Don't panic. These are routine repairs.
Modern garage doors have safety sensors near the bottom of the opening on both sides. These infrared devices prevent the door from closing if something blocks the path. Dust, cobwebs, or misalignment can trigger a false stop. Walk along both sides of your door opening and wipe the sensor lenses clean with a soft cloth. Make sure nothing is blocking the beam between the two sensors.
Realign the sensors if they're visibly crooked. Gently loosen the mounting bracket and angle the sensor back toward its pair. They should point directly at each other. After cleaning and alignment, test your door again. This single step resolves countless "stuck" complaints in Lexington and surrounding areas.

Look at the horizontal and vertical tracks on both sides of your door. Bent tracks or debris inside them can cause binding. Shine a flashlight along the full length and remove any dirt, leaves, or objects. If you spot a bent section, don't try to hammer it straight. That's a job for professionals.
The springs above your door carry enormous tension. Never touch them yourself. If a spring snaps, your door will drop suddenly and could cause injury. However, you can visually inspect them for obvious breaks or corrosion. Springs last 7 to 9 years with normal use. If your door is older and has never had spring work, this may be your issue.

If your opener is unresponsive, disconnect the door from the opener temporarily. Most openers have a red release cord hanging from the trolley. Pull it toward the front of the garage. This disengages the door so you can lift it by hand. Try opening and closing it manually. Does it move smoothly? Is it heavy or does it stick at certain points?
If the door moves freely, your problem is the opener or its wiring. If the door is stiff, sluggish, or won't stay up on its own, the springs are likely worn. A door that falls suddenly when you try to hold it open is a safety hazard and needs immediate professional attention. Visit our garage door repair services page to request an estimate.
You've checked power, cleaned sensors, inspected tracks, and tested the door manually. If it still won't work or behaves dangerously, call us. Some repairs require specialized tools and expertise. Opener replacement, spring tension adjustment, cable repair, and track straightening are best left to trained technicians. Attempting these yourself risks injury and further damage.

What should I do if my garage door is stuck halfway open? First, ensure the safety sensors are clean and aligned. Check for obstructions in the tracks. If the door won't move at all, pull the red release cord on the opener and try lifting it manually. Do not force it. If it's extremely heavy or won't stay open, springs may be broken and you need professional help immediately for safety.
Why does my garage door make loud grinding noises? Grinding sounds typically indicate worn rollers, damaged tracks, or lack of lubrication. Inspect the rollers for wear and the tracks for debris. Clean the tracks and apply garage door lubricant (not WD40) to the rollers and hinges. If grinding persists after cleaning, the rollers likely need replacement by a professional.
How much does garage door repair usually cost? Repair costs vary widely based on what's broken. Sensor cleaning is free if you do it yourself. Professional diagnostics and minor fixes like realignment run 75 to 150 dollars. Spring replacement or opener repair typically costs 200 to 500 dollars. We provide free estimates after inspecting your door.
Can I repair a broken garage door spring myself? No. Springs are under extreme tension and can cause serious injury if they snap. Always hire a professional for spring work. Attempting DIY spring repair is one of the most dangerous home repairs you can attempt.
How often should I have my garage door serviced? Annual maintenance prevents most problems and extends your door's lifespan. We recommend a professional tune-up each year to check springs, rollers, tracks, and opener function.
