In the case of home repairs and renovations, get professional help with screening your home for hazards and making repairs. If you hire someone to conduct renovation, repairs, or painting in a home built before 1978, make sure that they are certified by the Environmental Protection Agency to perform lead work.
A lead risk assessment will tell you if you have hard-to-find hazards such as lead dust, lead in bare soil, or lead in your water to prioritize any repairs you can have done. A lead-based paint inspection will tell you where the lead-based paint is in your home so you know the places (such as windows, doors, trim, porches, and other locations) to maintain and avoid disturbing. An abatement contractor knows how to eliminate hazards identified by either type of evaluation.
If you rent your home, report it to your landlord so that repairs can get made (and call code enforcement or a legal aid society if there is no response). If you own your home, keep your child away from renovation or maintenance work that disturbs paint, and make sure no paint chips or dust remain in the work area before your child enters.
