to : Saws with water would of course be optimal. But how can the parquet floor in a room be protected?
to : I want to know the exact pros and cons myself before awarding the contract and avoid trouble, since subsequent scheduled work depends on it. Because even with professional companies, there has unfortunately already been botch work, and liability afterwards is of no use to me.
You do not cut all the way through, but leave about 2cm, and build a dust wall/box on the parquet side. The rest that is still left is quickly snapped off.
