Garage Door Safety Inspection
On bright afternoons the door goes down a metre, stops, and climbs back up while the light on the opener blinks.
In plain words
After a vehicle or an object has hit the door, an inspection follows the force rather than the dent. A bump on the bottom section can nudge a track out of plumb, shift a roller, bend a bracket, or leave one cable seated differently on its drum, and each changes how the door hangs and how the springs share its weight. The technician traces the load path from the point of impact through the hinges, rollers, tracks, cables and counterbalance to the opener attachment, and reports whether the mark is cosmetic, whether a section or piece of hardware needs work, or whether the door has moved out of balance.
How the visit goesThere is a new sound. Last week the door simply hummed up and down; now there is a bang at the top of travel and a scrape on the way back, and you have started standing well back while it moves.

How the visit goes
A slow walk along the closed door
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.
Controls, release and lock
Each way of operating the door is tried in turn: the wall control, every remote the household uses, the keypad if there is one, and the lock or vacation button that disables the remotes. The technician checks that the wall control is mounted out of a small child's reach and within sight of the door, that batteries are fresh, and that the manual release cord hangs within reach with its handle intact and releases and re-engages the trolley cleanly. Any manual slide lock on the door is checked to make sure it is disengaged, since a door locked by hand while the opener is connected is a common cause of a bent rail.
Three checks you can repeat each month
The inspection leaves you with a short routine. Once a month, with the door closed, pull the release cord and lift the door by hand; it should move easily and hold at waist height. Reconnect the opener, lay a flat board on the floor and send the door down; it should reverse when it touches. Then start it closing and wave a broom handle through the photo-eye beam; it should reverse before contact. Each of these takes under a minute and mirrors what the technician did. If any of the three behaves differently from the day of the inspection, that is the moment to call, while it is still a small job.

What affects the quote
Maintenance done during the visit
Lubrication, photo-eye cleaning and alignment, fastener tightening and fresh batteries can be added on the spot. Each is a small line on the quote, chosen by you at the door.
A retest after repairs
When the report lists repairs, a short return visit to rerun the balance, reversal and photo-eye tests once the work is done is quoted as its own item.
What is stored around the door
Shelving under the spring shaft, bikes along the tracks or a car left inside slow the visual walk. Clearing the area beforehand keeps the inspection to its planned length.
What to have ready
- How many doors need inspecting, and are they all at the same address?
- When was the door last serviced, and do you have the paperwork?
- Have you tried lifting the door by hand, and how did it feel?
Garage Door Safety Inspection: questions
QuestionsWhat gets lubricated, and what is left dry?
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.
Is the inspection a repair visit?
It is a look and a record first. Small maintenance items such as lubrication, cleaning and aligning the photo eyes and tightening fasteners can be done on the spot if you wish. Anything involving spring tension, cables, drums, worn rollers or damaged sections is written up with a clear explanation and quoted as its own job, so you decide with the full picture in front of you.
What information helps when I call to book?
Whether the door is single or double and roughly how tall; whether there is a spring on a shaft above the opening or springs along the tracks; the opener make if you can see it; how many doors need looking at; what prompted the call and when it began; and whether anything happened to the door lately. A photo of the opener label and of the spring area is a useful extra.
