What to check before ordering a staircase

Ordering a staircase doesn’t start with choosing materials or design, but with checking the construction conditions on-site. One of the most important factors affecting the final result of the staircase is the straightness of the walls in the stairwell. If this aspect is overlooked before measuring and ordering, a visual problem may appear after installation that cannot be corrected by the staircase itself.

The staircase always follows the existing construction. It does not alter the geometry of the walls or correct previous construction deviations – rather, it clearly highlights them if the walls are uneven.

Wall straightness determines the relationship between the staircase and the walls

The staircase is designed and produced on-site according to fixed, smaller measurements and 90° angles. This means that the distance between the staircase and the wall is determined by the actual shape of the walls. If the wall is not straight, the gap between the staircase and the wall will not be uniform along the entire height of the staircase.

In such cases, it may happen that:

• the staircase is correctly measured and installed,
• the structure complies with the standards,
• yet there is an irregular gap between the staircase and the wall.

This is not a defect of the staircase, but a visible result of construction inaccuracy.

The staircase does not hide construction errors; it reveals them

A staircase is a long, linear structure that spans multiple levels. For this reason, it is one of the elements that most clearly shows whether the building has been constructed straight and correctly.

If the walls are:

• wavy,
• slanted,
• of uneven thickness,

this becomes particularly noticeable alongside the staircase. A staircase is not meant to hide construction errors or compensate for them visually – on the contrary, it highlights the quality of the construction.

Why you need to check wall straightness before ordering a staircase

Once the staircase is produced and installed, it is no longer possible to:

• alter the shape of the walls,
• redesign the staircase structure,
• correct visual irregularities technically.

Therefore, it is crucial that before measuring and ordering a staircase:

• wall straightness is checked,
• angles are verified,
• surfaces are plumb and final.

This simple inspection helps prevent situations where a staircase reveals construction errors, even if the staircase itself is of high quality and correctly manufactured.

Correct construction is a prerequisite for staircase quality

The staircase is always measured and produced according to the smaller dimensions of the stairwell, provided that:

• the walls are in their final dimensions,
• at least the base floor is finished,
• surfaces are plumb and corners are 90°.

A 5 mm installation tolerance is added to deviations, meaning that if a wall is 5 mm out of alignment, the gap between the staircase and the wall can be up to 10 mm. If these conditions are not met, construction inaccuracies are inevitably transferred to the staircase solution.

How to prevent problems between the staircase and the wall

The best way to avoid issues is to follow the correct order:

• construction check (wall straightness, angles, heights),
• correct walls if necessary,
• measure the staircase by a professional,
• order and produce the staircase.

This approach ensures that the staircase does not highlight construction flaws but fits as a clean and precise element in the space.

The staircase is a natural part of the construction and always follows the actual shape of the space. If the walls are not straight, this becomes inevitably visible alongside the staircase, even if the staircase itself is correctly measured and installed. Therefore, it is important to pay attention to wall straightness before measuring and ordering the staircase. Timely inspection and correction, if necessary, help avoid situations where the staircase reveals construction inaccuracies. When the construction conditions are correct, the staircase can fulfill its role as a natural, balanced, and space-fitting element.
