Never bypass, tape over or relocate the sensors to make a door close; a door that reverses is reporting something worth fixing.
In plain words
Photo-eye sensor service brings back the invisible beam that runs across the bottom of your doorway and lets the opener close with confidence. A technician clears the path, checks each sensor's indicator, tests the low-voltage wiring back to the head unit, and reads the opener's own diagnostic lights to tell an obstruction from a wiring fault. Brackets are straightened and refastened, lenses cleaned, and the pair aimed at each other at the same height no higher than 15 cm off the floor. If a sensor has failed, a matched pair for that opener family goes in. The visit ends with a beam test and a contact reversal test.

How the visit goes
- 1
Brackets and height on both sides
The two sensors have to sit at the same height, level, and facing each other squarely, no higher than about 15 cm (6 in) above the floor so the beam catches a small child or a pet. The technician measures both sides, because a bracket that has slipped a couple of centimetres down a track leg is enough to lose the beam. Each bracket is checked for bends from a bumper or a bin, for loose carriage bolts or wing nuts, and for rust where salt slush has sat against it for winters on end. A bracket screwed to a wall or the floor is checked for anchors that have worked loose.

Straightening or replacing the brackets
A bent bracket is straightened where the metal allows and replaced where it has cracked or rusted through. New brackets are chosen to suit the mounting: a track-mounted clip that rides the vertical rail, or a right-angle bracket anchored to the wall or the concrete where the track sits too far back. Fasteners that vibrated loose are replaced with the right carriage bolts and wing nuts rather than reused. Where a bracket has been sitting in salt slush every winter, it is set a touch higher within the permitted range and the mounting is sealed against the wall so water stops running behind it.

Wiring that stays put
The wire between the head unit and the sensors has been secured along the ceiling and walls, clipped clear of the track and, where it was exposed, run inside a protective channel. Two things keep it that way. First, when anything is fastened to those walls or that ceiling, from shelving to a bike hook to drywall, look for the thin wire before driving a screw or a staple. Second, if mice have been in the garage, a chewed wire is a common sign, so a dark sensor light after a sighting is worth a look at the run. Either way, the sensor lights will tell you the moment the circuit is open.

What affects the quote
- 1
Winter conditions on the day
Snow and ice packed against the brackets, a frozen bottom seal or a frozen floor where anchors must go all add a little clearing and care before the sensor work itself can start.

Undoing an earlier shortcut
Sensors taped together beside the motor, mismatched pairs from different generations or a bypassed circuit are put right first, which means new wire down each side and fresh brackets at the doorway.

Opener make and generation
Sensor pairs are matched to the opener family, and some models take a kit with brackets and wire while others take sensors alone. The head unit label sets which pair is needed and how it is priced.

Photo-Eye Sensor Alignment or Replacement: questions
What tests are done before the technician leaves?
Two, and you are invited to watch. With the door closing, an object is passed through the beam and the door has to halt and climb back to the top. A 2x4 laid flat beneath the door's centre comes next; closing onto it must make the door back off on contact. The door is also run from the wall control and a remote, the opener's warning flashes are confirmed gone, and both sensor lights are shown steady.
Do I need to be home for the work?
It helps. The technician needs access to the garage and the head unit, and the visit ends with a demonstration of the sensor lights and the two tests so you know what normal looks like. If you cannot be there, an adult who can open the garage is enough, and the written note left afterwards records what was found and changed. Having the strip of floor beside the door clear before arrival saves time either way.
My opener has no sensors at all. Can they be added?
If the opener predates the entrapment-protection standard, which operators have had to meet since the mid-1990s, its board has no sensor circuit and a pair cannot simply be wired in. The positive news is that a modern operator brings the whole package: matched sensors, force reversal and a monitored circuit. The technician confirms the model first, because some units do have the terminals and simply had their sensors removed.

What the census means at the door
58%
Older homes. About 58% of homes in Toronto were built in 1980 or earlier, according to the 2021 Census.
Where most houses were built a generation or more ago, a good share of garage doors are still the originals: wood or early steel sections on extension springs. Those doors respond well to fresh pulleys, safety cables and a careful balance, and the technician carries the parts for them.
23%
Single-detached houses make up about 23% of homes in Toronto (2021 Census).
Townhouses built in rows tend to have identical doors from the same builder, so when springs and openers age they do so together along the street. Owners often arrange service for several doors at once, and we can plan a single visit that covers the row.
