Hello,
After completing our new build, there is one remaining issue that nobody seems to take responsibility for. Next to the screed angles of the staircase, there are ugly gaps of about 1 x 10 cm (0.4 x 4 inches). These appear on all three floors, sometimes on one side and sometimes on both sides.

The architect had arranged for a company to apply PU (polyurethane) joints, but they never showed up. Now that we have a bit of time, we want to fix it ourselves.
What would you recommend? PU joint or something else?
Regards, Nicola

Exactly!
The idea with the steel piece or sheet metal would actually be the nicest. I just lack the tools to make it. I was hoping for an idea that might not be perfect, but at least nicer than the current gap and something I can manage with reasonable effort as a non-skilled person.

You can also order sheet metal cut to size online for a low price, or maybe there is a metalworker or roofer nearby.
Flat steel is also available at hardware stores; if the width suits your needs, you can simply cut it to length yourself with a saw. Or you could ask your neighbors—I recently cut something for a neighbor using an angle grinder...
Alternatively, you could try smooth wood painted to match, which might be acceptable since the paint is quite thick.

A proper wall connection is necessary here. A 3 cm (1.2 inch) gap is poor workmanship. The steel profile also doesn’t need an expansion joint. Nothing should move there.
A photo from above would also help to better understand the situation. In my opinion, the baseboard tile is also too short.
