- The call
- There are no sensors at the floor at all, or a previous owner has wired the pair together up beside the motor so the beam never crosses the doorway. A home inspector has just pointed it out.
In plain words
By the end of the visit you have a door that closes from every control and reverses the instant the beam is broken, a sensor pair mounted level at the right height with steady indicator lights, wiring that is secured and out of harm's way, and a written note of what was found and what was changed. The technician walks you through the two tests you can repeat monthly, points out which light is which, and leaves the opener's diagnostic chart where you can find it. It is a small job that puts a large piece of your door's protection back in service.

How the visit goes
Scene 1
Clearing and walking the beam
Before anything is adjusted, the technician clears the strip of floor between the two sensors and looks along the beam line at sensor height. Things that break a beam are rarely dramatic: the corner of a recycling bin, a hose left coiled by the wall, a bag of salt, leaves blown in under the door, a cobweb bridging a lens, a new weatherstrip or track shoe that sits a little proud. Snow and ice piled inside the door in winter count too. With the path clean, the door is tried again, because a fair share of sensor calls end right here, with a lesson about where things can and cannot sit.
Scene 2
Repairing the wire run
Damaged wire is dealt with in whole sections rather than patched at a single point. A pierced or chewed length is cut back to sound insulation and either spliced with proper connectors or, more often, replaced from the sensor to the nearest good junction. Where the run has failed in more than one place, a fresh two-conductor wire is stapled from the motor housing across the ceiling and down both sides of the opening, kept clear of the track, hinges and the door's travel. At the head unit the pair is landed on the correct low-voltage terminals with polarity confirmed, and the sensor lights are checked before anything is tidied.
Scene 3
Winter habits
In the cold months the sensors ask for a little attention. On frosty mornings give a misted lens a moment to clear rather than pressing close over and over, and wipe it with a dry cloth if it does not. Keep salt slush from building up against the brackets, since salt is what corrodes the mounts and terminals over time. Clear snow from just inside the door before closing it, and if the bottom seal has frozen to the slab, free it by hand rather than asking the opener to pull it loose. If the door closes at noon but not at nine, mention it; the low sun may be reaching the receiving eye and a shade sorts that out.

What shapes the quoteCootes Paradise Garage Door Pros
- Alignment or replacement
- Cleaning, re-aiming and refastening the existing pair is the smaller job. Fitting a new matched sending and receiving pair is the larger one, and the diagnosis at the door decides which applies before the quote is settled.
- Wall or floor mounting with anchors
- Mounting into concrete or masonry rather than onto the track means drilling, anchors and sealing against water, which takes more time than clipping to the rail.
- Force and travel adjustment alongside
- If the reversing turns out to involve a travel limit set long or a force setting made in summer, adjusting and re-testing those settings is included as a small extra step.

Things people wonder
How high off the floor should the sensors sit?
Low. The industry checklist expects the beam no more than roughly 15 cm (6 in) up from the floor, so that a small child, a pet or a bicycle wheel breaks it. Both sensors are set at the same measured height and level with each other, since a difference of a couple of centimetres is enough to lose the beam. Within that rule the technician can raise them a little to keep them out of the strip where slush collects.
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.
Can cold weather affect the sensors?
It can, in a few ways. Frost or condensation on a lens in an unheated garage dims the beam until it clears. The low winter sun reaches further across the floor and into a receiving eye. Old wire insulation cracks in the cold and shorts. Salt slush builds against brackets and corrodes them and the terminals over the years. Each of those has a straightforward remedy: cleaning, a shade or side swap, a fresh wire run, or brackets set above the slush line.

2021 census: what it means at the door
Every square is one home in a hundred.
- 61 in 100 homes · older homes
- 56 in 100 homes · mixed housing
- About 61% of homes in Hamilton 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.
- Single-detached houses make up about 56% of homes in Hamilton (2021 Census).Where housing is varied, security needs vary too. A detached home wants its garage door closing fully and its interior door respected; a townhouse or condo wants old fobs and remotes cleared and the shared entrance working. We address whichever applies at each door.

Someone backed the car in a little too far, a bin or a bicycle brushed the track, and since then the door starts to close and comes back up.
