Fort Myers · Lee County
A garage door that goes up fine and refuses to come down is nearly always telling you about its safety system, not its hardware. In Fort Myers the single most common cause is the pair of photo-eye sensors near the floor — and the second most common is something nobody warns Florida homeowners about at all.

Five causes cover almost every one of these we see in Fort Myers. They are not equally likely, and they are listed in roughly the order we find them.
Two small eyes sit about six inches off the floor on each track. They have to see each other. Knocked out of alignment by a bike, a bin or a vacuum hose, and the opener refuses to close — that refusal is the system working correctly. Look at the LEDs: on most brands one is steady and the other goes out or flickers when the beam is broken.
This is the Florida one, and it catches people every winter. When the sun drops low it can shine directly into a west- or east-facing sensor and wash out the beam. The door works perfectly all day and refuses to close for twenty minutes in the late afternoon. Nothing is broken. A small shade or re-aiming the sensor fixes it permanently.
Two lovebug seasons a year, year-round spider activity and salt haze on the coast all add up to a filmed-over lens. The beam weakens rather than breaking, so the fault is intermittent, which is the most frustrating kind. A microfibre cloth is sometimes the entire repair.
The opener has to be told where the floor is. If the down-limit is set too far, the door hits the concrete and the opener reads the resistance as an obstruction and reverses. Common after a new opener, a new floor coating, or any work that changed the door balance.
If a lift cable has slipped on its drum or a roller has seized, the door meets resistance partway down and the opener stops. This one is not a sensor problem and it is not cosmetic — it is the stage directly before a door comes off its track.
Do not hold the wall button down to force the door closed past the sensors, over and over. Most openers allow this deliberately as an override for a genuine sensor failure — but using it as a daily workaround means a door is closing with its safety system switched off, in a house where people walk under it.
The point of the visit is to find the cause, not to replace the first plausible part. On a call like this in Fort Myers:
Fort Myers has the oldest housing stock we work on and the broadest range. A McGregor Boulevard house may have a garage that predates the modern code entirely, with a wooden header and a door that was never rated for anything. Whiskey Creek and the 1970s neighbourhoods are on their second or third door. Gateway and the eastern communities are new enough that the original hardware is still in place and just reaching the end of its cycle life.
The housing here is largely everything from single detached garages on 1950s ranches to three-car openings in Gateway, plus a real amount of commercial roll-up work, with 1920s through to the present — the widest span of building ages in the region. Around the McGregor Boulevard historic homes, Whiskey Creek, Fort Myers Shores, Gateway, Colonial Boulevard and the downtown river district that shapes which of the causes above turns up most often.
Fort Myers sits far enough back that corrosion is a slow factor rather than an urgent one. The more common local pattern is heat and cycle count — plastic rollers and opener gears giving out early, and fasteners working loose over years.
What it costs. Sensor realignment and cleaning is the cheapest call we run. A sensor pair, a limit reset, or a roller set are all small parts. What makes this expensive is leaving it: a door forced shut on a binding roller is how panels get creased. We quote starting-from figures and we do not close a price before seeing the door. No call-out fee, no diagnostic fee, and no evening, weekend or holiday surcharge.
Depending on what we find, this call often ends up being one of these:
If the door is generally tired rather than faulty, a full service and the right wear parts is usually the better call, and we will say so.
Almost certainly low sun hitting a photo-eye sensor. The beam gets washed out for the window of time the sun is at that angle, then the door behaves perfectly again. It is a very common seasonal pattern in Fort Myers and it is fixed with a small shade or a slight re-aim, not with parts.
Usually a related one. Going back up immediately after starting down points at the sensors or at an obstruction; reversing just before it touches the floor points at the down-limit or close-force setting. The point at which it reverses tells us which.
You can bypass them, and you should not. They exist because children and pets have been killed by closing garage doors, and they have been required on residential openers in the United States since 1993. If a sensor has genuinely failed, it is an inexpensive part.
Then it is probably not the beam. The next candidates are the close-force and down-limit settings, then physical resistance in the travel — a seized roller, a cable off its drum, or a bind in the track curve. That needs eyes on the door.
It is safer than forcing it shut on an unknown fault, but it is not ideal in Fort Myers. If the opening has to stay open, the practical answer is usually a same-day visit rather than an overnight.
No call-out fee and no diagnostic fee, and no surcharge for evenings, weekends or holidays. You get a starting-from figure once we have seen what is actually wrong.
You get the price before anyone drives out, and if you decide not to go ahead you owe us nothing.
