Garage Door Safety Inspection
Your toddler has discovered the wall button.
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 goesDuring the power outage you pulled the red cord and tried to lift the door by hand. It felt like lifting a piano, and when you let go part-way it sank back toward the floor on its own.

How the visit goes
The opener head, its arm and its safety devices
Turning to the opener, the technician checks that the motor head is secure on its hangers, the rail is straight and its header bracket firmly fixed, and the curved arm meets the door at a bracket that is bolted to a reinforced section rather than thin steel. The chain, belt or screw drive is looked at for slack or wear. The photo eyes are located, their height above the floor noted, their lenses and wiring checked, and the wall control, remotes, keypad and lock or vacation button are each identified so they can be tested in turn. This is also where the manual release cord and handle are confirmed to be within reach and in working order.
Checking the photo eyes
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.
Repairs in a sensible order
If the report lists planned repairs, it also suggests an order, because some items lean on others. A cable showing rust at the loop comes before a new roller set, since cables are changed with the counterbalance unloaded and rollers are a simple job at any time. Springs near the end of their cycle life are planned as a pair, with the cables checked in the same visit. Photo-eye alignment and a stripped bracket fastener are done first because they are small and they matter. You can take the list in one go or over a few months; either way, nothing in it is a surprise when the technician returns.

What affects the quote
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.
Torsion or extension counterbalance
Extension-spring doors add pulleys, cable clips and containment cables to the list, while torsion doors call for spring measurements at the shaft; the parts examined shape the time.
The kind of report you need
A plain findings sheet suits most households. A photographed, measured report for a sale, a rental file or a property manager takes longer to prepare and is quoted as such.
What to have ready
- Has a vehicle or anything else struck the door or the tracks?
- How many remotes, keypads and wall buttons operate the door?
- What prompted the call, and when did you first notice it?
Garage Door Safety Inspection: questions
QuestionsWhy does my door reverse on the way down for no reason?
Most often it is the photo eyes. A sensor knocked slightly out of line, a lens with a film of road grime, a loose wire, or low afternoon sun shining straight into one eye will each break the beam as far as the opener is concerned. The next candidates are a down-force setting that has drifted, a binding roller or a door that has gone out of balance. The inspection checks each in turn.
My opener is old and has no photo eyes. Can it still be inspected?
Yes. Older openers rely on contact reversal alone, so the board test carries more weight and is run carefully against the maker's procedure, along with the manual balance check, the force setting and the release. The report records what the opener has and how it performed. An opener built before photo eyes became standard is flagged for replacement in the report, since makers recommend moving off that generation of opener rather than treating photo eyes as a nice-to-have.
What is the board test?
It is the contact-reversal check. A short length of 2x4 lies flat on the floor in the middle of the opening and the door is closed from the wall button. When the bottom edge meets the wood, the door should halt and travel back up without help. Passing shows the opener's down-force and travel limits are set to back off from something solid. The technician never substitutes a hand or foot for the board.
