- 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
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
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
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
The monthly beam test
The habit worth keeping takes about a minute. Once a month, with the door open, press close on the wall control and, as it moves down, pass a broom handle through the beam near the floor. The door should stop and climb back to fully open. Then lay a 2x4 flat under the middle of the door and close onto it; the door should touch it and reverse. If either test fails, stop using the opener; close the door first if it is not already closed, then use the manual release, and get help moving it by hand if it feels heavy or will not hold. A door that passes both tests is doing its job.

What shapes the quoteMount Nemo Door Specialists
- An opener without a sensor circuit
- Where the operator predates monitored sensors and cannot accept a pair, the quote changes shape into a modern operator with its own sensors, which is discussed as a separate decision rather than folded in.
- 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.
- Access to the doorway and the head unit
- A clear strip along the floor and a reachable head unit make for a direct job. Shelving, vehicles or stored goods that must be moved to reach the sensors, wire or terminals add time.

Answers in plain language
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.
What do the small lights on the sensors mean?
Arrangement varies by model: most pairs carry an indicator on each side, in differing colours for sender and receiver, though some older pairs light only the receiver, so check the maker's chart. A receiving light that is dark or flickering means the beam is not landing on it, so the pair needs aligning or something is in the way. Both lights dark means the pair has no power, which points to the wire or the terminals at the head unit. Steady lights on both sides mean a healthy system.
How should I clean the lenses?
Gently, with a soft dry or lightly damp cloth, the way you would clean eyeglasses. Never scrape a lens or use a solvent, since a scratched or clouded lens scatters the beam. Wipe both sensors, then check that the receiving light comes on steadily. If a lens frosts on cold mornings, give it a few minutes to clear or dry it with a cloth. A quarterly wipe keeps dust, cobwebs and salt film from building up.

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.Older houses frequently have a garage door that was replaced once already, sometimes with a door chosen for the opening rather than the building. When that door reaches its end, there is a chance to pick a style that suits the house properly, and we measure with that in mind.
- Single-detached houses make up about 56% of homes in Hamilton (2021 Census).Mixed housing often means mixed access too: individual remotes and keypads on the houses, building fobs and shared gates on the condos. We program, clear and replace all of these, and keep property managers in the loop where a door serves more than one household.

Since shelving went up along the garage wall, the door will not close and both sensor lights are dead.
