They charge about 60-80€ per hour. He billed 1.5 hours for a simple clarification of the matter with us. At an hourly rate of 62€. By wood installation do you mean OSB board as a carrier for the floor? Or floorboards? I can't imagine what you mean by that.

Thanks, that's actually less than I feared!

Exactly, we were told that these are basically chipboards made of wood, which are screwed or nailed. That's why the floor squeaks when you walk on it.

Ah yes, we also got that nonsense like this from the previous owner. But for your year of construction, it is somehow a strange construction (we have wooden beam ceilings and this was often retrofitted later). Are you sure there is no screed? Somehow I just can't imagine that.

I looked it up and apparently this is not uncommon, especially on the upper floors of prefabricated houses. If the structural engineer does have concerns, I would probably install underfloor heating and then pour screed on top. That way, you don’t have to mill the concrete ceiling. And maybe someone else will chime in here and provide input.

Hm, so far we only have the statement from a specialist company that would retrofit the underfloor heating. And relatives who think they remember (the house is from the family). Unfortunately, we don't really know what is under the PVC. Maybe we need to open a spot and see what layers the substrate has.

You should do that, yes. What you really have is often only known in older houses when you actually open it up. And then think about it. You also have to make sure that the new height still fits the doors, stairs, etc. You have to consider all of that. And for that, you first need to know exactly what is there and how thick each layer is. Then you can think about how to rebuild.
