What Are the Health Risks of Lead Paint Exposure?
Last updated October 26, 2026
The short answer
How Lead Paint Harms the Body
Lead is a toxic metal that the body absorbs like calcium. Once inside, it interferes with enzyme function and nerve signaling. The effects build up over time, so even low-level exposure adds risk. No amount of lead is considered safe for children or adults.
The most serious damage happens to the brain and nervous system. In children, this can slow development and cause learning problems. In adults, lead can raise blood pressure and harm the kidneys. Pregnant women face added risk because lead can pass to the fetus.
Who Faces the Highest Risk
Young children are the most vulnerable because their bodies are still growing. They often put hands and toys in their mouths, which can pick up lead dust from floors or windowsills. Their brains absorb lead more easily than adult brains do.
Pregnant women also face higher risk because lead can cross the placenta. Older homes with peeling paint or recent renovations can create dust that spreads through the house. If your home was built before 1978, lead paint may be present under newer layers.
- Children under six years old
- Pregnant women and fetuses
- People doing DIY renovations
- Anyone with high blood pressure
- Workers in older buildings
Symptoms of Lead Exposure
Symptoms often appear slowly and can be easy to miss. In children, look for irritability, fatigue, and trouble concentrating. You might also notice a loss of appetite or slowed growth. These signs do not mean your child has lead poisoning, but they are a reason to see a doctor.
Adults may experience headaches, muscle pain, or memory issues. Long-term exposure can lead to mood changes and digestive problems. If you feel unwell and suspect lead exposure, see a doctor for a blood test. Only a medical professional can confirm whether lead is the cause.
How to Limit Exposure at Home
The first step is to keep painted surfaces in good condition. Peeling or chipping paint creates dust and chips that are easy to swallow. Clean floors, windowsills, and toys with a damp cloth often to reduce dust buildup. Use a HEPA vacuum for carpets and upholstery.
Wash children's hands before meals and after playing outside. Do not dry-scrape or sand old paint, as that spreads dangerous dust. If you plan to renovate, test for lead first. For help with water-damaged walls that may contain lead paint, local water damage pros can assess the situation safely.
- Damp mop floors and sills weekly
- Wash toys and pacifiers often
- Use cold water for drinking and cooking
- Keep play areas away from painted walls
- Wipe shoes at the door
When to Call for Professional Help
If you find peeling paint in a home built before 1978, do not handle it yourself. Disturbing the paint can release toxic dust into the air. A mold professional or a lead abatement specialist can test surfaces and safely remove hazards. For water damage that has caused paint to bubble or flake, the pros can help identify the source first.
Your insurance company may or may not cover lead abatement costs. Policies vary, and your insurer decides what is covered. Check your policy and ask about testing options. Do not delay if you see damaged paint, because the risk grows with every chip that falls.

Can lead paint affect adults differently than children?
Yes. Adults may face high blood pressure, joint pain, and memory issues. Children are more at risk for brain damage and developmental delays. Symptoms vary by age and exposure level, so a blood test is the only way to know for sure.
How do I know if my home has lead paint?
Homes built before 1978 likely have lead paint under newer layers. You can buy a home test kit from a hardware store, but results are not always reliable. A professional inspection gives a clearer answer, especially if you plan to renovate.
Is it safe to stay in the house during lead paint removal?
Staying during removal is risky because dust spreads easily. If possible, leave during the work and for a few days after. If you cannot leave, seal off the work area and clean thoroughly afterward. Ask the pros about their containment methods before they start.
