Installing stairs - these points are important

Of course, stairs always differ in terms of their design, construction and processing. However, there are some basic rules that are always in place for installing stairs, and some things that should be considered. Which are these, read here.

Bulk goods and individual production

Stairs can either be DIY stairs or made to measure individual pieces. Self-built stairs are assembled by the homeowner from a modular system and usually self-installed, while custom-made usually the staircase builder takes over the installation of the stairs.

This also has an effect on the liability: When self-installation, there is hardly any liability on the part of the manufacturer, because virtually everything can be pushed to assembly errors. If the stair builder takes over the installation, he is also liable for a professional execution of all installation work.

If the staircase builder takes over the installation of the stairs, you usually do not have to worry about much. If you do that yourself, things look different.

First rule: check dimensions

The most important thing to do before you even start to build a staircase yourself is to check that all the dimensions you have taken are in fact correct, if all the walls in the assembly area are even, and if so, the dimensions of the stairs vote. Even in wooden staircases it can sometimes come to mistakes.

Even professional staircase builders always follow this rule.

Second rule: check the stairs

Before mounting, the staircase should be carefully checked for faults, defects or deviations. Complaints are usually only possible before installation. Everything that is overlooked here can later become problematic.

Only when the stairs have been found to be okay, you should start with the installation.

Third rule: strictly follow the manufacturer's instructions

For all prefabricated stairs, an installation instruction is usually included. The information and sequence on the assembly instructions must always be strictly followed, otherwise the stability of the stairs may suffer. This is especially true for pedestal steps, where it is particularly important which stages are already mounted during installation and when fitting, and which are not.


The following points are important when setting up a staircase:

  • Check dimensions
  • Check staircase for dimensions and damage
  • Follow manufacturer's instructions and order strictly
  • If possible, adapt the fixings to the conditions in your own home

Tips & Tricks

When attaching the stairs, always pay attention to where you attach them. Concrete is not the same as brick wall, screeds are not a sufficiently stable layer for the lower edge of the staircase (stairs should always be fastened to the raw concrete, observe shrinkage).
