Garage Doors: questions, answered with sources
Each answer cites the public sources it was checked against, with the date it checked them. Jobs that need a licensed pro in Virginia say so, and explain the job instead of teaching it.
Cable Repair
3 answers
How are snapped garage door cables replaced?
A trained door technician replaces them. The job means releasing the door's tension safely, fitting a new cable at the bottom bracket and the spring drum, and resetting spring balance. Clopay's manual says springs, cables and bottom fixtures are under strong spring tension and warns of severe injury, so book a pro and keep clear of the door.
How much does it cost to replace a snapped garage door cable in Virginia?
We found no dated Virginia price from a primary source, so we do not quote one. The cost depends on whether one cable or both are replaced, what else the break damaged, any spring work, door weight, parts and timing. Get at least three written quotes for the same scope, as the Virginia DPOR advises, and ask each for a licence number.
Why did my garage door cable snap?
Most lift cables fail from wear: fraying and rust at the bottom bracket, friction on the drum, or strain after the door jumped its track or hung unbalanced. Clopay's manual warns that springs, cables and bottom fixtures are under strong spring tension, so do not touch them or run the door. Have a door technician find the cause.
Door Alignment
4 answers
What does realigning a garage door track involve?
A technician checks that the vertical tracks sit parallel to the door and level with each other, that the horizontal tracks are level and square, and that the brackets and hangers are tight and braced. It is a job for a trained door pro, because the tracks, bottom brackets, cables and springs are held under spring tension.
How much does garage door track alignment cost in Virginia?
There is no dependable Virginia price list for track alignment, and a cost figure with no date and no source would be a guess. The bill depends on whether the track only needs adjusting or is bent, whether rollers, hinges or springs are involved, and the trip charge. Look at the door from the floor, then get written quotes that split parts from labor.
Why is my garage door crooked when it opens?
A door that rises crooked usually has a track that has shifted or bent, loose track supports, a worn roller or bent hinge on one side, or springs and cables that no longer lift evenly. Look from inside with the door closed, note which side lags, and stop using the opener. Anything touching the springs, cables or bottom brackets is for a pro.
How do I keep garage door tracks aligned?
Keep tracks aligned by checking them monthly: run the door by hand, look for a gap that changes or a rubbing roller, and tighten loose track supports without overtightening. Wipe the tracks clean, oil rollers and hinges once a year, and never grease the tracks. Anything bent, or near the springs and bottom brackets, goes to a pro.
Hinge Repair
3 answers
How do I replace a broken garage door hinge?
Replace a broken middle or top hinge with the door closed, the opener disconnected, and only one hinge undone at a time. Match the number stamped on the old hinge. Do not touch the bottom corner brackets or anything attached to the lift cable: they are under heavy spring tension. If the broken hinge is down there, call a pro.
Why are my garage door hinges cracking?
Cracked hinges usually mean the door is asking more of them than they were made for: loose screws that let a hinge flex, a door that binds in the track, a door that has gone out of balance, or simply years of use. Fix the cause, not only the hinge. Top and middle hinges are a home repair; the bottom corners are a pro's job.
How do I keep garage door hinges from cracking?
Oil the hinges once a year, tighten any loose screws, wash the door a couple of times a year, and test its balance by hand every month so a weak spring does not overload the hinges. Replace a bent hinge early, one at a time. Leave springs, cables and bottom brackets to a door technician.
Noisy Door Repair

Off-Track Door
3 answers
What should I do if my garage door comes off its track?
Stop and leave the door where it is. Do not run the opener, push the door back, or touch the springs, cables or bottom brackets. One door maker's manual warns that operating a door with damaged track could be hazardous, and that those parts are under strong spring tension. Keep people and cars clear, and call a professional door repair service.
What does it cost to put a garage door back on its track in Virginia?
There is no dated Virginia price list for this repair, and an undated figure would be a guess. The bill runs from a visit to reset and tighten a door to new track, rollers or springs. Ask for written quotes that list parts, labor and the trip charge separately, and check the licence first if the job reaches $1,000.
Why did my garage door come off its track?
Usually something knocked the door or the track out of true: an impact, a loose or bent track, a worn roller, or a spring or cable problem that left the door lopsided. A door that binds or sticks is a warning sign. Because springs, cables and bottom brackets are under strong tension, have a professional find the cause.
Opener Repair

Remote & Keypad Repair

How do I program my car's built-in garage door opener?
Park outside the garage, clear the built-in buttons if this is the first time, then hold your handheld remote 1 to 3 inches from the car's button and press both until the light changes. If the light flashes rapidly, you have a rolling code opener: press the Learn button on the motor unit, then press the car button within 20 seconds, up to 3 times.
How much does it cost to replace a garage door remote or keypad in Virginia?
When we checked on October 27, 2026, Chamberlain listed its 3-button visor remote at $39.99 and its wireless keypad at $44.99. That is the part price before any technician visit. Labor, a new receiver for an old opener, or a trip charge add to it, so ask any Virginia pro for a written quote that separates parts from labor.
Why did my garage door remote stop working?
The usual cause is a worn-out coin-cell battery, so replace that first. If a fresh battery does not help, the opener may have lost the remote's code and it needs reprogramming with the Learn button. If the wall button fails too, the problem is the opener or its power, not the remote.
How often should I replace the battery in a garage door remote?
There is no set schedule: replace it when the remote's range shrinks or it needs several presses, and not before. A coin cell loses very little just sitting, so the wear comes from use. Keep a fresh spare, and recycle the old cell instead of binning it.
Roller Repair
3 answers
How do I replace garage door rollers?
You can replace the rollers on the hinges and the top bracket yourself, one at a time, with the door closed and locked and the opener disconnected. Do not touch the bottom corner brackets or the roller in them: they are under heavy spring tension. If a bottom roller is the bad one, or the track is bent, call a pro.
Why are my garage door rollers wobbling or popping out of the track?
Wobbling rollers are usually worn out: broken wheels, bent stems or worn bearings. Popping out of the track points to a bent or spread track, loose hinges or track supports, or a door that has gone out of balance. Replace worn hinge rollers and tighten hinge screws yourself. A bent track or any bottom corner bracket is a pro job.
How often should garage door rollers be replaced?
No manufacturer here sets a fixed number of years. Rollers are checked every year and replaced when they show broken wheels, bent shafts or worn bearings, or when the door gets noisy or wobbly. Oil them yearly, and keep the check going. Replace the hinge rollers yourself; leave the bottom corner ones to a pro.
Sensor Repair
3 answers
How do I align garage door safety sensors?
Check that both sensors sit at the same height, 4 to 6 inches above the floor, and that the lenses are clean and face each other with nothing in the beam. Loosen the wing nut or bracket screw on the one that is off, aim it at the other until your opener's indicator lights show steady, snug it, then test the door's reversal with a 2x4.
Why won't my garage door close when the opener light blinks?
The blinking opener light usually means the safety sensors cannot see each other: something is in the beam, a sensor has been knocked out of line, a lens is dirty, or sun is shining into the receiving eye. Clear the beam, wipe the lenses, check both sensor lights, then re-aim. The blink count differs by brand, so check your manual.
How do I keep garage door sensors working?
Wipe both sensor lenses and test the door's reversal about once a month, keep bins and tools out of the beam zone, shade the receiving sensor from direct sun, and check the thin sensor wires for staples and nicks. Re-aim a sensor that has been bumped and replace one that has gone dark or will not stay clean.
Spring Replacement

Weather Seal
4 answers
How do I replace the bottom seal on a garage door?
Find out what kind of retainer is on the bottom edge of the door, because seals are not interchangeable. Disengage the opener, raise the door, clamp both tracks, slide out the old seal, slide in the new one, and trim it leaving two extra inches that you tuck in. Do not touch the bottom corner brackets or the springs: they are under heavy tension.
How much does a garage door bottom seal replacement cost in Virginia?
There is no reliable published Virginia price for this job, so be wary of any single number. The cost depends on the retainer type, the door width, an uneven floor and whether the retainer is damaged. Get at least three written estimates that name the seal, the labor and any trip charge, and compare them on identical specifications.
Why is water getting under my garage door?
Usually the bottom seal is worn, cracked or drooping, or the slab at the threshold is uneven or slopes toward the door, so water collects there and finds a gap. Rain pooling against the door from poor drainage outside makes it worse. Check the seal and where the water comes from first, then fix the seal or add a threshold seal.
How do I keep a garage door seal from cracking in winter?
Before freezing weather, rinse the seal, clean it with a vinyl cleaner, and coat it with a silicone-based lubricant. Avoid petroleum-based oils, which attack rubber and reduce its flexibility. Keep water from pooling under the door, use sand rather than salt on ice, and replace a seal that is already cracked, dried out or droopy.
