DIY aluminium cladding installation guide

The DIYers guide to installing aluminium cladding.

These steps are designed to help an installer of aluminium cladding typically follows, from measuring up to order and then installation:

Measuring Up:

  • Measure the exterior walls of the building where the aluminium cladding will be installed.
  • Note any architectural features affecting the cladding layout, such as windows, doors, corners, and other protrusions.
  • Take accurate measurements of these features and areas to ensure precise fitting of the cladding panels.

Material Selection:

  • You should choose the type of aluminium cladding based on factors such as the desired finish, colour, texture, and thickness.
  • We’ll advise on any additional components needed for the installation, such as corner pieces, trim, fasteners, and adhesive.


  • Based on the measurements and material selection, calculate the quantity of aluminium cladding panels needed for the project.
  • Place an order, ensuring the required specifications are met.
  • Confirm the lead time for delivery is in line with your schedule and contact us to ensure the timely arrival of the materials.


  • Prepare the exterior walls for installation by cleaning and inspecting the surface for defects or imperfections.
  • Repair damaged areas and ensure the substrate is smooth, clean, and debris-free.
  • If necessary, apply a moisture barrier or insulation layer to the substrate to improve energy efficiency and protect against moisture intrusion.


  • Start by installing the ‘top hat’ rails and any necessary corner pieces or trim to frame the edges of the cladding panels.
  • Begin attaching the aluminium cladding panels to the exterior walls, starting from one corner and working horizontally or vertically, depending on the preferred layout.
  • Secure the panels using the appropriate fastening method; we recommend screws, ensuring that they are spaced evenly and aligned correctly.
  • Use a level to check the alignment of the panels periodically and make any necessary adjustments to ensure a straight and uniform installation.
  • Cut the panels to size as needed to fit around windows, doors, and other architectural features.
