- The call
- Backing out in a hurry, the bumper tapped the bottom section. The dent is small and the door still runs, but it seems to shudder now at the point where the panel meets the track.

You moved in three months ago. The door works, but nobody can say how old the springs are, when anyone last looked at it, or whether the little sensors by the floor have ever been tested.
What you get back is a report with four kinds of entry. Items that are in good order, so you know what is fine. Maintenance items, such as lubrication or a loose hinge bolt, which are often handled during the same visit if you wish. Repairs to plan, such as a worn roller set or a cable showing rust at the bottom loop, quoted separately. And, rarely, a stop-use item, where the door should stay put until a specific part is corrected. That last category is the reason the inspection exists, and the report says plainly which items fall into it.

Garage Door Safety Inspection · Collison Heights

Scene 1
With the door down and the light on, the technician looks at every section from the top down: dents, bowing, cracked stiles, a strut that has come loose. Each hinge is checked for a split leaf or a missing bolt, each roller for a cracked wheel, a bent stem or one that slides instead of turns. The tracks are sighted for plumb and even spacing from the door, and each track bracket and lag into the jamb is checked for tightness. This is unhurried work with a light and a mirror, and it finds the small things, a hinge working loose, a roller stem walking out, that become the big noise next season.
Scene 2
The photo eyes are the pair of small sensors low on each track that watch the opening with an invisible beam. The technician confirms they are mounted at the height the opener maker specifies, aligned so the indicator lights hold steady, clean of grime and frost, and wired securely. Then, with the door closing, the beam is broken with an object; the door should reverse before it reaches anything. A sensor that has been knocked out of line, wired loosely or blinded by low sun explains a great many doors that refuse to close on some afternoons, and the fix is often alignment and a wipe of the lens, done on the spot.
Scene 3
The most useful thing about a first inspection is the second one. With the model numbers, spring dimensions, cable condition, seal gaps and photo-eye heights on record, the next technician can measure the same points and tell you what has moved rather than starting from nothing. For most households an annual visit fits, with a look in early spring after the salt season a natural choice. A door that carries a lot of traffic, an older door, or one in a rental where nobody watches it closely may suit a check each season. Whatever the interval, the report you are holding is the reference the next one will be read against.

The moving metal-on-metal points get a light coat: the spring coils, the hinge knuckles, the roller bearings and the pins at the bottom brackets. A silicone or lithium product made for doors is used, then the door cycles a few times to carry it in. The tracks are the exception; they are cleaned and left bare, since a slick track lets the wheels skid and holds grit against them.
Yes, plainly and at the door. A slack or frayed cable, a gap in a spring coil, a door hanging crooked, a bracket pulling out of the framing or an opener that fails the reversal test are the kinds of findings that put an item in the stop-use group. When that happens you see the reason yourself, the door is left resting in a safe spot with the opener unhooked, and the fix is written up and quoted so it can be booked.
They are the two small sensors low on each side of the opening, one sending a beam and the other receiving it. The technician confirms both indicator lights hold steady, that the units sit at the height the opener maker specifies, and that the lenses are clean and the wiring secure. Then a close cycle is started and something is passed through the beam; the door should reverse. Misalignment or a grimy lens is corrected on the spot.
