4. Consider Hiring a Certified Lead Abatement Contractor or Inspector
Anytime you cut into surfaces painted with lead paint, even if the paint is covered by layers of newer paint, you risk creating hazardous lead dust. You can reduce the risk of lead exposure in your home by hiring a certified lead inspector to check to see if there is lead paint in the area of your work.
If there is lead, then you may want to have a trained and certified lead abatement contractor perform an abatement to remove the lead from the area before you begin work.
