Garage Door Won't Close All the Way is best traced from the most likely cause to the least likely, using the visible behavior before any part is touched.
01Close all the Way Garage Door Won't: Down-travel limit set short
For Garage Door Won't Close All the Way, this check matters because the opener believes the door is closed when it is still a few inches up, so it stops and does nothing further. The most common single cause of a persistent gap, and a straightforward limit reset for a technician.
Do not attempt this yourself. It is under spring or cable load and it injures people every year - this one is a licensed-technician job.
02Close all the Way Garage Door Won't: Obstruction in the track near the floor
For Garage Door Won't Close All the Way, this check matters because a bolt head, a bent track lip or a lump of hardened grease near the bottom of the vertical track stops the roller short.
Safe to check yourself, with the door closed and the opener unplugged.
03Close all the Way Garage Door Won't: Worn or missing bottom weather seal
For Garage Door Won't Close All the Way, this check matters because sometimes the door is closing correctly and the gap is a perished astragal seal. A new seal is inexpensive and also keeps out the rodents and the winter runoff.
Safe to check yourself, with the door closed and the opener unplugged.
04Close all the Way Garage Door Won't: Uneven or heaved slab
For Garage Door Won't Close All the Way, this check matters because older California slabs settle and lift, especially where a driveway apron has been re-poured or a tree root is at work. A threshold seal absorbs an uneven floor better than any adjustment can.
Do not attempt this yourself. It is under spring or cable load and it injures people every year - this one is a licensed-technician job.
05Cable slack letting one side sit high
For Garage Door Won't Close All the Way, this check matters because uneven cable tension leaves one corner off the floor. Cable work happens with the springs unloaded, by a technician.
Do not attempt this yourself. It is under spring or cable load and it injures people every year - this one is a licensed-technician job.
06Bowed bottom section
For Garage Door Won't Close All the Way, this check matters because a wide door with an under-reinforced bottom section can bow upward in the middle over time, leaving a crescent of daylight even when the door is fully down. A strut fixes it.
Do not attempt this yourself. It is under spring or cable load and it injures people every year - this one is a licensed-technician job.
Close all the Way Garage Door Won't: What to do about it
How urgent is this, honestly?
For Garage Door Won't Close All the Way, not an emergency, and anyone who tells you otherwise is selling you an after-hours rate. 2 of the 6 causes here are things you can check yourself in the next few minutes, and a meaningful share of these resolve without anybody being dispatched. What it is worth doing is not ignoring it. Garage door faults are progressive: the thing that is currently an inconvenience is attached to a component that is wearing, and the cost of the eventual repair goes up rather than down while you get used to working around it.
Work through these first, in this order
For Garage Door Won't Close All the Way, there are 2 things on this list you can check safely yourself, with the door closed and the opener unplugged, and they are ordered here by how often they turn out to be the answer rather than by how interesting they are. Start with obstruction in the track near the floor, then worn or missing bottom weather seal. None of these needs a tool you do not already own, none takes more than a couple of minutes, and each one you rule out makes the phone call shorter and the price band tighter if you do end up needing one. The reason to do them in order is that the common causes are also the cheap ones, and diagnosing from the expensive end is how people end up replacing a working opener.
What you should not touch
For Garage Door Won't Close All the Way, 4 of the causes on this page are genuinely not a homeowner job: down-travel limit set short; uneven or heaved slab; cable slack letting one side sit high. That is not us protecting our own work. A torsion spring stores enough energy to kill and releases all of it the moment a winding bar slips; a lift cable under load will cut through a hand; a door that has left its track is carrying its weight unevenly and can drop without warning. The tooling matters as much as the technique and the technique is not obvious from a video. Everything else on this page - the checks above, the lens cleaning, counting diagnostic flashes, testing balance with the opener disconnected - is safe. These are not, and the injuries are severe rather than inconvenient.
What a technician will actually do
For Garage Door Won't Close All the Way, the visit follows the same order as this page, deliberately: cheap causes ruled out before expensive ones are quoted. The checks you have already run get repeated - not because we doubt you, but because "I cleaned the lenses" and "I cleaned the lenses and both LEDs then glowed steady" are different pieces of information. Then the components come into it in ascending order of cost, which for this fault means working toward down-travel limit set short rather than starting there. You get a written figure before any work begins. If something else turns up once a cover is off, the honest thing is to stop and re-quote, and that is what happens rather than a bigger number appearing on the invoice at the end.
If none of it explains what you are seeing
For Garage Door Won't Close All the Way, then it is probably two things at once, which is more common than people expect because garage door components wear in groups. A spring at the end of its cycle life has usually been dragging on a cable for months; a door slightly out of balance puts load on an opener that then fails in a way that looks unrelated; a track bent in an old impact produces a binding that presents as a completely different fault a year later. This is also why a diagnosis that explains most but not all of what you are seeing is worth pushing on: "the sensors were misaligned" is a complete answer only if realigning them actually fixed it. Describe everything you have noticed, including the things that seem unrelated - the noise last month, the one time it stopped halfway - because that is usually where the second fault is hiding.
Stopping it happening again
For Garage Door Won't Close All the Way, most repeat failures on this fault come from one of three places. The repair addressed the symptom and not the cause, which is why a competent visit finds out why rather than only what. The door was left out of balance, so whatever was compensating for it carries on compensating and fails again on schedule - the balance test takes fifteen seconds with the opener disconnected and it is the single most useful thing a homeowner can learn. Or a component was replaced without its pair: springs, cables and rollers all work in matched sets, and a new one working against a fatigued one is a repair with a countdown attached. A service interval of one to two years on a door running four to six cycles a day catches all three before they become call-outs.
What it costs to put right
For Garage Door Won't Close All the Way, editorial California planning range: $150–$450 depending on the failed component for opener repair across California, and where a specific job lands inside that band comes down to which of the causes above turned out to be yours, the door's weight and size, and whether anything failed alongside it. The two things that reliably move a quote in the wrong direction are cycling a broken door repeatedly before the visit, which turns small repairs into large ones, and accepting a figure without asking what it includes. Ask whether cables are in it, what cycle rating the springs are, what the warranty covers on parts, and whether the trip is included - four questions that turn a spread which looked like price into a spread that is mostly specification.
What to tell whoever else is in the house
For Garage Door Won't Close All the Way, worth thirty seconds, because the person who causes the second problem is usually not the person who found the first. Tell them what the door is doing and that it should not be operated until it is looked at - particularly not repeatedly, which is the instinct. Tell them not to pull the red emergency release handle if the door is open: that disconnects the trolley from the opener, and on a door with a failed spring the opener may be the only thing holding it up. Keep vehicles and bicycles out from under it, and if there are children in the house, keep the wall control out of reach for the day. None of that is alarmist - a garage door is the heaviest moving object most households own, and the failures on this page are precisely the ones that change how it behaves.
The parts this fault actually involves
For Garage Door Won't Close All the Way, four components do the work on any garage door and knowing which one this fault sits in makes the rest of the page easier to read. The springs counterbalance the door's weight - they, not the opener, are what makes a 300lb door liftable by hand - and they are rated in cycles rather than years. The cables transfer that counterbalance from the spring to the bottom of the door, in matched pairs, and they fail from the inside where you cannot see it. The track and rollers guide the door's path and tolerate very little misalignment before they bind. And the opener guides an already-balanced door and provides the safety systems - photo-eyes, auto-reverse, force limits - that stop it closing on something. The causes flagged as professional on this page sit in the first two of those, which is why they are flagged.
If you have already tried something
For Garage Door Won't Close All the Way, say so on the call, and be specific about what happened rather than what you did. "I cleaned the lenses" and "I cleaned the lenses and both LEDs then glowed steady but it still reversed" are different pieces of information, and the second one eliminates a cause that the first one does not. The things worth mentioning that people usually leave out: anything that changed recently, including work done by somebody else; whether the behaviour is consistent or intermittent, because intermittent points somewhere quite different; whether it is worse at a particular time of day, which on sensor faults is often the whole answer; and anything you heard in the weeks before it failed. A door rarely fails without warning - it fails without the warning being recognised.
What this does to the rest of the door
For Garage Door Won't Close All the Way, nothing on a garage door fails in isolation for long, and this fault is no exception. While it is unresolved, the load that component was carrying goes somewhere else - usually onto the opener, which was designed to guide a balanced door rather than to lift an unbalanced one. That is why a fault left for a few weeks so often ends with two invoices instead of one, and why the second one is for a motor that was working perfectly before. The practical version of this is that the cost of the eventual repair goes up rather than down while you work around it, and the components that get damaged in the meantime are usually more expensive than the one that started it. That is the whole argument for dealing with it this week rather than next month, and it is arithmetic rather than urgency.
Getting a straight answer on the phone
For Garage Door Won't Close All the Way, three answers diagnose the majority of these before anyone is dispatched. What it sounds like - a single bang, a grinding scrape, a motor humming with no movement and a click with nothing are four different faults. Where in its travel it stops - six inches off the floor, halfway, or just before it seals, each pointing somewhere different. And what the lights are doing, because most openers flash a diagnostic code before they give up and counting the flashes usually narrows the fault to a single component. Add the door's rough size and whether it is insulated and you have enough for a real price band. None of that is a form; it is a two-minute conversation, and it is the difference between a quote and a diagnostic fee.
