How do I know if my home has lead paint?

Question

Accepted Answer

Start with the calendar. The EPA says homes built before 1978, when lead-based paints were banned, probably contain lead-based paint, and the older the house, the more layers of it. Lead paint that is intact and undisturbed is low-risk; the danger arrives when it peels, cracks, or gets sanded and turned into dust, because children can be poisoned when they swallow or breathe in lead dust, and dust is invisible. The telltale signs: paint chipping or peeling in a pre-1978 home, chalky dust on windowsills and floors, and chew marks on old woodwork. Testing is definitive: an EPA-certified lead inspector can test paint surface by surface, and home swab kits exist but are less reliable. The rules if you have it: do not dry-sand or scrape old paint yourself, keep painted surfaces intact and clean dust with wet methods, and hire certified renovators for any work that disturbs old paint, which US law requires for pre-1978 homes. If you have young children in an older home, ask your doctor about a simple blood lead test, because lead poisoning often shows no symptoms until damage is done, and kids absorb more than adults.
