Installation of a sectional garage door

The installation of a sectional garage door involves the professional fitting of a multi-panel, vertically opening door system within a garage opening. The door is guided upwards via side guide rails and positioned beneath the ceiling. For the door to function reliably over the long term, all components must be precisely matched – particularly the door panel, guide rails, spring system and garage structure.

Installation requirements

Structural requirements

  • Precisely measured garage opening
  • Load-bearing, level foundation
  • Sufficient headroom and side clearance for guide rails
  • Sturdy wall construction (e.g. precast concrete garage)

Technical requirements

  • Precisely fitting door system (made to measure or standardised)
  • Suitable spring system (tension or torsion spring)
  • Optional: Power connection for electric drive

Installation procedure (step-by-step)

  1. Preparing the garage opening
  2. Cleaning, checking dimensions and ensuring the surface is level.
  3. Fitting the guide rails
  4. Side and horizontal rails are precisely aligned and secured.
  5. Inserting the door sections
  6. The individual panels are inserted one after the other and connected to one another.
  7. Installation of the spring system
  8. Tensioning the springs to compensate for the weight of the door leaf.
  9. Integration of the drive (optional)
  10. Installation and connection of an electric door drive including control unit.
  11. Adjustment and functional test
  12. Checking smooth operation, safety functions and end positions.

Common mistakes when installing yourself

  • Inaccurate alignment of the rails
  • Incorrect spring tension
  • Inadequate fixing to the garage structure
  • Lack of safety checks

These errors can lead to malfunctions or safety risks. We therefore recommend that installation is carried out by qualified personnel.

Solution: Professional installation from a single source

With coordinated system solutions (e.g. precast concrete garages with integrated doors), installation is usually completed within a single day. All components are designed to work together, minimising the need for readjustments.

FAQ

How long does installation take?

Installation is usually completed within one working day.

Is retrofitting possible?

Yes, existing garages can be retrofitted with a modern door.

Can the installation be carried out by the customer?

Technically possible, but not recommended due to the complexity and safety requirements.
