How to identify lead paint<br>Determine if the paint is from 1970 or earlier. Most homes built before 1970 often have lead-based paint on the walls, doorways, stairwells, and baseboards. If your home is old and you know it was built in the early or mid 1900s, it may have lead-based paint.
If a house was built in the early 1940's, it's unlikely that it never had any lead-based paint in it.
