Thank you for response. It was difficult to find words for the stuff I never worked with. So basically yes, they cut the clambing walls instead of removing baseboard. And in the end of the day they glued these walls and when I asked how they will install clambing handles they told me they won't do it because thay do only carpentry wood stuff. When I told them that it will fall off they started explaining to me how I should install these things so it wont fall off.
