You can paint over lead paint, or “encapsulate” it with a special paint that includes an ingredient called an encapsulant. The EPA approves encapsulation as a lead paint removal method as long as the paint remains undisturbed. Standard types of paint without an “encapsulant” from the big box stores or hardware stores do not meet EPA standards for remediation of lead-based paint.

If your home was built before 1978, there’s a chance that any paint on your hardwood floors could be lead paint—especially if it was already there when you moved in. Because lead is toxic, hiring a licensed pro to remove it is mandatory. The average price for professional lead paint removal ranges from $1,500 to $5,300 and depends on the scope of the project.

Exterior paint contains a higher level of VOCs, which can be dangerous if you’re exposed to it for a long period of time. The good news is that paint’s toxicity reduces significantly once fully dried and cured. Do not keep open exterior paint cans in your home, basement, or garage, exposing your household to harmful chemicals over time.

Unfortunately, lead dust does not look different from any other type of dust. You cannot detect it with the naked eye. To determine if you have lead dust in your home, you will need to hire a local company to take a sample from the paint and test it for you in a lab.
