Hi,
a surcharge of 26.3 euros is really cheeky, but there’s not much you can do about it. For us, it was 16 € for 90*22 cm wood-look porcelain stoneware.
This consisted of a surcharge for laying porcelain stoneware instead of tiles (because it requires a different adhesive during the day, which is about 4-5 euros/sqm more expensive) and the rest was a surcharge for the larger format.
The floor has to be level anyway; with 120*30 it might of course need some smoothing.
Craftsmen are currently charging astronomical prices. The only way to resist that is to make it clear to them that with such prices, you will expect an absolutely 100 percent flawless job. In other words: your tolerance for errors should be absolutely zero!
Those who demand astronomical prices must also deliver absolute perfection!
For us, that meant that for gaps at the edges a 6 mm wide tile had to be cut with a water jet instead of just sealing it with silicone. I simply did not accept that.
Moreover, the tiler has since come back 5 times for corrections, each time traveling 30 km. In hindsight, he probably didn’t earn much from us after all.
Regards,
Andreas
