A door you barely notice.

A repair is not finished when the part is in. We run the door through its full travel several times, check that it stays put at half height, test the photo-eyes with an obstruction and confirm the opener reverses on contact. Only then do we hand the remote back.

A garage door belongs to the architecture. Its movement belongs to your everyday life. We bring both into the conversation.

  • No pushing. You hear the choices once, clearly. Whether to go ahead, wait or take a different route is yours to decide.

1/3Off-Track Garage Door Reset

The rollers on the door have been squealing for months. Today one of them simply fell out of the track at the curve, its wheel worn down to the stem, and the top section sagged sideways as the door opened.

2/3Garage Door Opener Replacement

Since the storm the door behaves oddly: it reverses halfway down for no reason, the light flickers, and the travel limits drift so it either slams or stops short. The board inside is discontinued and the last repair only bought a few months.

3/3Torsion Spring Replacement

Nothing broke outright, but the door has grown heavier each winter, opens more slowly and squeals as it moves. The springs on an older door have lost tension and the coils show pitting, so the system is asking for attention before it fails.

Springs & Hardware

A loud bang from the garage with nobody in it is nearly always a spring letting go. The door will not open properly after that, and it should not be forced. These services get the lifting system rebuilt safely.

  1. Torsion Spring Replacement

    One side of the door sits higher than the other in the tracks, and a lift cable is hanging slack or has jumped off its drum.

  2. Garage Door Cable Replacement

    The door went up as usual this morning, then stopped a third of the way with one corner higher than the other.

  3. Garage Door Roller Replacement

    A roller near the top corner is riding on the lip of the track rather than inside it, and the section above leans back a little more each week.

  4. Photo-Eye Sensor Alignment or Replacement

    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.

Garage Door Opener Diagnosis and Repair

The motor runs, the chain rattles along the rail, and the door does not move a millimetre. You notice the little carriage sliding back and forth on its own.

Chain-Drive Opener Repair

The door closes, touches the floor, then climbs straight back up as if it hit something. Nothing is in the way, the sensor lights are steady, and it has been doing this since the weather turned.

Belt-Drive Opener Repair

After the power came back you pulled the red cord to get the car out. Since reconnecting, the door stops short of the floor, and no amount of turning the limit adjustment brings it the rest of the way down.

Garage Door Opener Replacement

The remotes only work from the end of the driveway now, and one of them disappeared with a set of keys last month. Inside the remote are tiny switches instead of a learn button, so excluding the missing one means resetting the switch pattern on every remote and the receiver.

Photo-Eye Sensor Alignment or Replacement

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.

Smart Garage Controller Setup

The house came with a controller already screwed to the garage ceiling and a sensor on the door, but the app insists the device belongs to another account. The seller has moved provinces, the emails go unanswered, and every evening the door still reports to a stranger's phone.

Emergency Release Repair

It is the coldest morning of the year. A week of slush and road salt has crusted over the outside release lock, the key will not seat, and the opener inside is silent after the overnight outage.

How a visit goes

Describe the property, the hardware and what has changed, and the visit starts from what you have seen.

  1. 01

    Getting the details

    We ask about the door's age, the type of springs, the opener and what changed. A photo of the hardware helps us bring the right stock.

  2. 02

    Testing the balance

    With the opener disconnected we raise the door by hand. It should lift with light effort and stay put at waist height; if not, we know where to look.

  3. 03

    Completing the repair

    Parts are replaced, settings adjusted and the safety sensors tested. You get a summary of what was done and what to keep an eye on.

2021 Census

What it means at the door

About 38% of homes in Mississauga were built in 1980 or earlier, according to the 2021 Census.

Mixed neighbourhoods often include renovated older houses with a new facade and a garage door that no longer suits it. Choosing a door that ties the renovation together, then installing it plumb and balanced in an older opening, is work we do regularly and enjoy.

Single-detached houses make up about 37% of homes in Mississauga (2021 Census).

In denser housing the garage door is frequently the main entrance to the home and sits close to the living space, so a door that closes fully and locks properly matters for security. We check the closing force, the lock and the opener's stored codes on every visit.

Short answers

Questions · (289) 724-5854

Should I lubricate the tracks?

No. Tracks should be clean and dry. Rollers are meant to roll along the track on their own bearings, and a film of lubricant on the track collects grit, thickens in the cold and makes the rollers slide and drag instead. Wipe the tracks with a rag and put the lubricant where it belongs: on the hinge pins, the roller bearings, the spring coils and the bearing plates at the ends of the torsion shaft.

What does a garage door tune-up actually include?

A full cycle observed before any work, a hands-on inspection of hinges, rollers, tracks, springs, cables, drums, brackets and the opener's attachments, tightening of the accessible fasteners, lubrication of the moving points with a garage door lubricant, a balance check with the door disconnected from the opener, adjustment of the opener's travel and force, cleaning and alignment of the photo-eyes, both reversal tests, a look at the seals, and a written record of the findings.

What is the balance test and why does it matter so much?

With the door closed, the opener is disconnected using the red release handle and the door is lifted by hand. A balanced door rises with modest effort, stays fully open and holds still about a metre off the floor. The springs are meant to carry nearly all the weight so the opener only guides the door. A heavy or sinking door means the opener is lifting weight it was not built to lift, wearing its gear and making the reversal system less reliable.

Do sensors wear out with age?

They do, slowly. The infrared emitter and the receiver dim over many years, lenses craze or cloud from sun and salt, housings crack, and water finds its way in at floor level. A pair that needs re-aligning more and more often, or whose light drifts between steady and flickering with nothing touched, is usually ageing. Because pairs are matched to the opener, an older opener is worth identifying early so the right replacement is on hand.

My car is inside the garage; how do you get the door open?

Once the technician is on site, the door is secured and the spring replaced with the door in its closed position, which is how spring work is always done. When the new spring is wound and the door balances, it lifts normally and the vehicle drives out. There is no need to force the door open beforehand; leaving it closed keeps the door square and the job straightforward.

Request a visit

For customers in Mississauga the sequence is always the same. Assess the door in person. Explain what was found and why. Price the options on site. Do the agreed work with the door secured and the right tools. Test every part of the travel. Show you what changed. Then clean up and go.
