Every part of the door, and who fixes it

Forty-four services across five groups. Start with the diagram if you know roughly where the trouble is, or the questions below if you do not.

Call (248) 982-5399 Describe the problem
A garage door seen from inside the garage, with the parts labelled and each label linking to the service page for that component: torsion spring and shaft, cable drums, lift cables, vertical and horizontal track, rollers, hinges, panels, bottom seal, opener rail and motor, and the safety sensors at floor level Torsion spring and shaft Cable drums Opener and rail Rollers Track Hinges Panels Bottom seal Safety sensors

Seen from inside the garage. Every label goes to the page for that component.

Start with what the door is doing

Six situations that cover most calls. Pick the closest and it takes you to the right page.

  • The door will not move and the car is stuck

    A snapped spring, a derailed roller or a tripped opener. Do not keep pressing the button.

    Emergency repair
  • It closes then reverses straight back

    Four different components produce that one symptom, so all four get checked.

    System diagnostics
  • It has started making a noise

    Grinding, banging, squeaking, rattling or popping. Each points somewhere different.

    Grinding noise
  • It is heavier than it used to be

    Usually spring tension, and it is worth catching before the spring goes rather than after.

    Spring repair
  • It opens by itself

    Never random. Five causes, checked cheapest and most likely first.

    Opens on its own
  • Nothing is wrong yet

    The point of a tune-up. Seventeen checkpoints, run in sequence.

Repair

When something has already gone wrong

Every repair call starts with a diagnostic. We find the cause before quoting the fix, because the loudest symptom is often not the failure.

A door part-way through its travel with the three moments a fault shows itself marked: at startup, mid-travel and at the closing point At startup Mid-travel At the close Where it happens narrows what it is.

Fault by cycle position

Springs, cables and track

The parts that carry the weight

Springs store the energy that lifts the door, cables transfer it, and the track guides it. These are the components that make a door heavy or dangerous when they go.

Torsion assembly

Openers and entry

Everything electronic

Openers, remotes, sensors and access control. Most opener faults are read off the control board in about ninety seconds rather than guessed at.

Doors and upkeep

New doors, and keeping them right

Installation, replacement, insulation and the scheduled work that stops the rest of this list becoming necessary.

Commercial

Bays, not garages

Cycle volume rather than the calendar sets the maintenance interval, and downtime is the cost that matters.
