I am getting replacement windows becuz my current windows have lead paint on them. After getting the windows replaced should I stay out of the house for a while due to the lead dust. I have a newborn and a six year old?
A good vacuuming should get the rest (if they didn't sand the existing windows - and there really isn't a reason they should have). There will probably be more sawdust than anything, and the filter on the vac should keep that from being exhausted out of the vacuum.
Also, you may want to wipe down any flat surfaces with a tack-cloth, instead of just dusting afterward.
There shouldn't be any lead dust, only a little saw dust.
Yes, it is real, however to relieve your fear, have a new higher rated air filter placed on your furnace right after the new windows are installed. The lead paint is usually not a problem unless a child would chew on the painted surface,lick it,etc.
Parts per million of lead in the air are minimal unless you are sanding a lead painted surface.
