Garage Door Opener Repair in Laval & Greater Montreal
Chain, belt and screw-drive openers diagnosed and repaired: gears, logic boards, sensors, remotes, travel limits and force settings.
What we do
Garage Door Opener Repair in Greater Montreal
Openers fail in a few predictable ways: a stripped drive gear, a logic board damaged by a power surge, misaligned safety sensors, a worn trolley, or settings that have drifted out of range.
Before replacing an opener we check the door itself. An opener that keeps failing on a heavy, unbalanced door is a symptom, not the cause.
What the job includes
- Diagnose whether the fault is the opener, the door, or the power supply
- Replace stripped nylon drive gears and worn sprockets
- Replace or repair logic boards, capacitors and wall controls
- Realign and replace photo-eye safety sensors and wiring
- Reprogram remotes, keypads and vehicle-integrated controls
- Reset travel limits and force settings after any door repair
- Replace worn trolleys, chains, belts and rail hardware
Common problems
What usually goes wrong
These are the failures we are actually called out for, and what each one usually means.
The motor runs but the door does not move
Classic stripped drive gear or a disengaged trolley. Check whether the release cord has been pulled before assuming the worst.
The door closes then immediately reopens
The safety sensors are misaligned, dirty or obstructed, or the close force is set too low. Both are quick fixes.
The remote works only from a few feet away
A weak remote battery, a failing antenna, or radio interference from an LED bulb or a nearby device.
The opener flashes a code and refuses to close
Nearly all modern openers use blinking LEDs to report sensor or limit faults. Reading the code is the fastest route to the cause.
The opener strains and stops in winter
Cold stiffens lubricants and the bottom seal can freeze to the slab. The opener reads the extra resistance as an obstruction.

Reviews
Garage Door Opener Repair — what customers say
Jobs like yours, across Laval, Montreal and the surrounding suburbs.
“Door would reverse right before it touched the ground, every single time. Turned out to be the photo eyes knocked out of alignment plus a drifted limit setting. Twenty minutes, no parts, no upsell. Explained what to watch for next time.”

“Spring went on a Sunday morning with the car locked inside and my wife needed to be at work. Sent a photo over WhatsApp, got a straight answer on what it was and what it would cost before anyone drove out. Both springs replaced and the door is quieter than it has been in years.”
Marc-André L.

“Two other companies told me the whole door needed replacing. These guys came out, found a bent track and worn rollers, fixed both, and charged a fraction of what I was quoted elsewhere. Honest is the word I would use.”

Pricing
What actually drives the price
No two garage door jobs price the same, and any company quoting you a firm number before seeing the door is guessing. Here is what changes the figure — you get the real one after the diagnosis, before any work starts.
| Job | What moves the price | Worth knowing |
|---|---|---|
| Torsion spring replacement | Door weight and height, single vs matched pair, spring cycle rating | Always replaced in pairs on a two-spring door so balance is kept. |
| Cable replacement | Whether drums need re-spooling, condition of the bottom brackets | Usually paired with a balance check, since a snapped cable means the door ran uneven. |
| Opener repair | Gear kit vs logic board vs sensors, brand and age of unit | A stripped nylon gear is a repair. A failed board on a 15-year-old unit often is not worth it. |
| Opener replacement | Chain, belt or wall-mount; horsepower for door weight; accessories | Belt drive is worth it when there is a bedroom above the garage. |
| Panel / section replacement | Availability of a matching section, insulated vs non-insulated | Has to be ordered to match — this is the one job that is rarely same-visit. |
| Full door replacement | Size, insulation R-value, window inserts, new tracks and hardware | Includes correctly sized springs and a re-set opener, not just the door. |
Fastest way to a real number: send a photo of the door, the spring above it, or the opener unit. WhatsApp is usually quickest — you often get an assessment back before a technician is dispatched.
FAQ
Garage Door Opener Repair questions
Is it worth repairing an opener or should I replace it?
A gear, board, sensor or remote repair on an otherwise healthy unit is usually well worth it. If the unit is old, lacks photo-eye safety sensors, or is underpowered for the door, replacement is the better investment.
Why does my door reverse before it closes?
Most often misaligned or dirty photo-eye sensors near the floor, or a close-force setting that is too low. Both are adjusted during a service call.
Can you reprogram my remotes and keypad?
Yes, including wall keypads and in-vehicle buttons where the opener supports them.
My opener has no safety sensors. Is that a problem?
Photo-eye sensors have been required on residential openers for decades. An opener without them should be replaced rather than repaired.
