A customer called last Tuesday morning. His garage door wouldn't close past the halfway point. He'd tried the remote, the wall button, even the manual release. Nothing worked. Fifteen years on the job, I've seen this a hundred times. The good news: most of these jobs are fixable fast. The bad news: ignoring it costs more later.
A garage door that won't close all the way is a security risk and a headache. The culprit is usually one of five things: misaligned sensors, a broken spring, track obstruction, opener issues, or a damaged bottom seal. Knowing which one you're dealing with saves time and money on your repair estimate.
The photo-eye sensors sit on both sides of the garage door frame, about six inches up from the ground. They send an invisible beam across the opening. If that beam breaks, your door won't close as a safety feature. This happens more often than you'd think.
Walk down and look at both sensors. Are they dusty? Covered in cobwebs? Knocked out of alignment by a car or bike? Wipe them clean with a soft cloth. If one is angled away from the other, gently adjust it back into position. The little red and green lights should both glow solid. If you still see blinking, they're misaligned and need adjustment.
Sometimes the wires get pinched or cut. Check the cable running from each sensor up the frame. Look for damage, kinks, or places where the garage door itself might be rubbing. This is one of the easiest things to troubleshoot at home, and it solves the problem in roughly 30 percent of calls we take.
If your sensors look fine, the issue might be mechanical. A broken spring removes about half the door's lifting power. The opener motor still tries, but the door gets stuck. Springs last seven to nine years under normal use. If yours is older and your door won't open or won't close smoothly, a spring replacement is likely.
Check your tracks next. Debris, bent metal, or rust can stop a door mid-descent. Shine a flashlight along both sides. Remove any visible leaves, dirt, or objects. If you see a dent or severe misalignment, that's a job for a professional. Don't try hammering a track straight yourself.

Your garage door opener has a safety reverse feature. If the door hits an obstacle while closing, it stops and reverses. This protects people and pets. But if your reverse sensitivity is set too high, the door treats even normal resistance as an obstacle and bounces back up.
Locate your opener's adjustment screws. There are usually two: one for open force and one for close force. Some newer models have digital controls. The manual should tell you which is which. Small clockwise turns increase closing force. If you're not comfortable adjusting this yourself, leave it to the pros. A wrong adjustment can disable your safety system.

If your sensors are clean, tracks are clear, and the opener adjustment doesn't help, you need a technician. Broken springs, damaged openers, and electrical faults aren't DIY jobs. They're also not cheap to ignore. A spring that breaks mid-repair becomes a safety hazard and costs more to fix later.

What if my garage door closes but bounces back up? This usually means the safety reverse is too sensitive or something is blocking the door's path. Check for debris in the tracks first. If the path is clear, the opener's close-force setting is likely too high or the sensors need cleaning. If it persists, a technician should inspect the door and opener for damage.
Can I manually close my garage door if the opener is broken? Most modern doors have a manual release cord (usually red) that disconnects the opener. Pull it and the door becomes manual. You can lower it by hand, though it will be heavy. Never try to use the opener again until it's repaired professionally.
How much does a garage door repair cost in Westbrook? Basic repairs like sensor cleaning or track adjustment run 75 to 150 dollars. Spring replacement costs 200 to 400 dollars depending on the type. Opener repairs range from 150 to 500 dollars. Call for a free estimate before committing to any work.
Why won't my garage door close in cold weather? Cold thickens lubricant and can make springs stiffer. If your door stalls only in winter, apply a silicone-based lubricant to the tracks and hinges. Avoid WD-40 on tracks; it attracts dust. If the problem persists year-round, the spring or opener likely needs professional attention.
Is a stuck garage door a security risk? Yes. A door that won't close leaves your home and possessions exposed. Thieves and weather can damage your garage. Have any stuck or slow-closing door repaired within a day or two. Same-day service is available if you call us early.
