ᐅ Is it still acceptable if the floor is uneven at the edges?

Hello forum,

We have the following situation. The floor rises slightly towards the room wall, so every shelf placed there ends up leaning and needs significant shimming at the front to stand straight.

The construction company says something about 6 mm (0.24 inches) per 1 m (3.3 feet) being acceptable. But the problem occurs over much less than 1 m (3.3 feet). Over about 60 cm (24 inches), there is already 8 mm (0.31 inches) or 10 mm (0.39 inches) of deviation. Starting from the first tile, everything is level again.

Furthermore, the construction company says the screed will be ground down at the edges to eliminate this effect. I’m afraid they didn’t grind anything in my case.

Or maybe the tiler laid the first row of tiles unevenly, not level. That would surprise me anyway, since he should have checked the tiles with a spirit level, so he shouldn’t have been able to finish with them out of level.

Diagram: Shelf leaning against wall on tiles, instructions for alignment with 5–10 mm (0.2–0.4 inches) gap.


What should I do now? Any suggestions? The construction company is kind of brushing off the issue. In my opinion, I shouldn’t have to prove that they are wrong; rather, they should prove to me that everything was done correctly when I raise such complaints.

I know the relevant DIN standard and the table. According to that, only about 3 mm (0.12 inches) would be allowed over the short distance, not 8 mm (0.31 inches).

Table with limit values in mm and measurement point distances in m (DIN 18202).

Report the defect and have it repaired.

Is this a defect?
Due to scheduling reasons, we have already moved in. The final payment has not been made yet.

Fixing it would be a major undertaking. All floor coverings would need to be removed, the floor leveled, and the coverings reinstalled.

The construction partner is not at fault for this.
First, have a discussion. Then find a solution.

Doing it correctly from the start would have been easier. But that’s not your problem.

That would be interesting.
