- The call
- After a cold night the door stays open until the garage warms up. There is frost on the sensor lenses and a ridge of salty slush piled against the brackets where the snow blower was parked.
In plain words
Two small sensors face each other across the doorway: one sends an infrared beam, the other receives it. While the beam lands on the receiver, the opener will close the door; the moment anything interrupts it, the door stops and returns to open. Every sensor call comes down to why the receiver has lost the beam: an object, a bent bracket, a dirty or frosted lens, sun in the receiving eye, a broken wire or a tired sensor. The technician works through those in order, fixes the one that applies, and shows you the steady indicator lights that mean the pair is talking again.

How the visit goes
Scene 1
Making sure it is the sensors and not the door
A door that reverses on the way down has two possible reasons, and only one of them lives at the floor. If the door touches something, including a bottom seal frozen to the slab, a travel limit set slightly long or a stiff door in cold weather, the force setting sends it back up. That looks like a sensor fault from the driveway but calls for a different fix. The technician checks whether the door reverses before it moves or after it meets resistance, watches the sensor lights during the cycle, and tries the door with the beam deliberately shaded. The answer decides whether the work stays with the sensors or moves to the settings.
Scene 2
Cleaning and protecting the lenses
Lenses are wiped with a soft cloth and a mild cleaner, never scraped, and the housings are checked for cracks that let in water. Sensors that have been sitting in the strip where slush and salt collect are raised within the permitted height range and their brackets sealed. On a wall where the wire runs exposed, a slim protective channel keeps it clear of bins and bikes. Where mice have been at the wire, the new run is routed higher along the wall and dropped straight down to each sensor. These small measures are what keep a repair from repeating the following winter.
Scene 3
Keeping the brackets out of harm's way
Most repeat sensor calls come from the same few habits, and they are easy to change. Keep recycling bins, bicycles, boots and the snow shovel away from the bottom of the door track on both sides. Park with a little room to spare so a bumper never meets a bracket. When you sweep or blow snow out of the garage, aim away from the sensors rather than at them. If shelving or a workbench goes in along that wall, leave the strip near the floor free. The brackets are sturdy, but they hold a precise line, and a nudge that would not bother anything else is enough to lose the beam.

What shapes the quoteSaugeen Door Specialists
- Protecting exposed wire
- On a wall where the wire runs in the open, a slim protective channel or a re-route higher along the wall keeps bins, bikes and mice away from it, and is quoted as its own line.
- 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.
- Corrosion reaching the head unit
- Where salt and water have travelled up the wire to the terminals, or the sensor terminals on the board are damaged, the repair extends beyond the pair and that is set out separately.

Your questions, answered
How do I test the sensors each month?
Start the door closing and, while it is moving, swing a broom handle through the beam low across the opening; the door should halt and travel back up. Next, put a 2x4 flat beneath the door's centre and run the door onto it; it should back off as soon as it touches. If either test fails, close the door first if you can, use it by hand with the manual release, and book a visit; do not release it if it feels heavy.
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.
How long does a sensor visit take?
Alignment, cleaning and a bracket adjustment are done inside an hour on most doors, including the two tests at the end. Replacing the pair adds a little for wiring and setup. Re-running the wire all the way from the motor to both sensors is the part that stretches a visit, especially where the wire is behind a finished ceiling or the garage is full. Having the floor by the door clear before arrival helps.

2021 census: what it means at the door
Every square is one home in a hundred.
- 59 in 100 homes · older homes
- 88 in 100 homes · mostly houses
- About 59% of homes in West Grey were built in 1980 or earlier, according to the 2021 Census.Older garages tend to have lower headroom and narrower single openings, so replacement doors and openers are chosen to fit the space rather than the other way round. Measuring the header, side room and ceiling depth is the first step on every one of these visits.
- Single-detached houses make up about 88% of homes in West Grey (2021 Census).Detached homes usually have their own driveway and apron, and years of freeze and thaw can leave the concrete uneven where the door meets it. A thicker bottom seal or a threshold strip closes the gap, keeping snow, leaves and cold air out of the garage.
