We're renovating our house, and our contractor has already started painting while demolition of three bathrooms is still ongoing. There's construction dust everywhere.

We also have two doors to install, a fireplace to demolish and rebuild, and old blinds, nails, and wires that still need to be removed.

Is this a normal sequence of work? Shouldn't demolition and other dusty work be completed before painting starts? Am I right to be concerned?
