If lead is a real concern and the owner insists it be remediated, then test each area of the home to find out where lead is actually present. As stated below, just because a home is old does not automatically contains lead-based paint. Vice versa: itâ€™s always possible that a newer section of a home was painted with an old can of paint that contained lead.
Test the entire home and remove lead only in those areas where it is actually located. And make sure you use a licensed contractor with a lead removal certification.
