Lead Paint in Older Homes: What Every Homeowner Needs to Know
If your home was built before 1978, there's a strong chance it contains lead-based paint. Lead paint was used in millions of homes across the United States before it was banned by the federal government. Today, it remains one of the most common — and most preventable — sources of lead poisoning, especially in children.
Why Lead Paint Is Dangerous
Lead is a toxic metal that can cause serious health problems, especially in children under 6. Even low levels of lead exposure can cause:
- Developmental delays and learning difficulties in children
- Behavioral problems and reduced IQ
- Kidney damage and nervous system damage in adults
- Reproductive problems
- High blood pressure and cardiovascular issues
The danger comes when lead paint deteriorates (chips, peels, or creates dust) or is disturbed during renovation. Lead dust is invisible and can be ingested or inhaled without knowing it.
Where Lead Paint Is Found
Lead paint can be on virtually any painted surface in a pre-1978 home:
- Windows and window frames — The #1 source of lead dust due to friction when opening/closing
- Doors and door frames — Similar friction creates lead dust
- Trim, baseboards, and molding — Often have many layers of old paint
- Walls and ceilings — Especially in older rooms that haven't been renovated
- Exterior siding and porches — Deteriorating exterior paint contaminates soil
- Stairs and railings — High-wear areas where paint chips easily
When Testing Is Required
Lead testing is recommended or required in several situations:
- Before renovation: The EPA's RRP (Renovation, Repair, and Painting) Rule requires certified lead-safe practices when disturbing painted surfaces in pre-1978 homes
- Before buying or selling: Federal law requires sellers to disclose known lead paint. Buyers should test before purchasing
- If you have young children: Children are most vulnerable to lead exposure. If your home is pre-1978, testing gives you peace of mind
- If paint is deteriorating: Chipping, peeling, or chalking paint in an older home should be tested
What to Do If Lead Is Found
If testing reveals lead paint in your home, don't panic — but do take it seriously:
- Don't disturb it. Intact lead paint that's in good condition is generally not an immediate hazard.
- Get a professional assessment. Our Industrial Hygienist can evaluate the risk level and recommend next steps.
- Consider abatement. For deteriorating paint or areas that will be renovated, professional lead abatement permanently eliminates the hazard.
- Never sand or scrape lead paint yourself. This creates dangerous lead dust. Always use certified professionals.
The Bottom Line
Lead paint is a manageable hazard — but only if you know it's there. Professional testing is quick, affordable, and gives you the information you need to protect your family.
