While watching the episode where Kevin and Tom are installing some of the new windows, I noticed that Tom cut away the existing plaster from two of the new window openings as well as a section next to the stairs which opened up the view from the foyer.

They took no precautions before removing these sections of plaster like they did before removing the other walls and plaster on prior episodes. There was no plastic on the floors, they didn't wrap the removed plaster in plastic for disposal, and neither Kevin nor Tom was wearing any protective suits, masks or gloves.

What happened? Seems unlikely that those three areas of the house had no lead paint.

I am also an EPA certified contractor and what they did there doesn't jive with the training I received.

Anybody have an answer? Maybe someone from the show or a moderator from this site?

Very curious.
