Should you test for lead paint before painting an older house?

Updated November 10, 2026 · KeystoneProGuide editorial team

Do you have to test before painting?

No. The Environmental Protection Agency says paint testing is not required under its rule for renovation and painting. But the rule works the other way round: unless there is documentation that the paint is not lead-based, a painter working for pay in a pre-1978 home must treat it as lead paint and follow the lead-safe requirements. So the real question is whether a test would tell you something worth knowing before the work starts.

What can a test tell you?

That depends on which kind you buy. The EPA and the Centers for Disease Control and Prevention describe three levels.

• A lead paint inspection tells you whether the building has lead paint and where it is. It does not tell you whether that paint is a hazard now, or what to do about it. The Pennsylvania Department of Health says an inspector can find lead paint even under other layers of paint.
• A risk assessment tells you whether there are lead hazards from paint, dust or soil, and what actions to take. The CDC describes it as the test that finds serious hazards such as peeling paint and lead dust.
• A renovator's test is narrower: a certified renovator can check specific components that a job will affect, with an EPA-recognized test kit or by sending paint chips to an EPA-recognized laboratory. A result showing a component is lead-free takes that component out of the rule.

The EPA says the only way to know for certain whether a building has lead paint or lead hazards is to have it tested.

Who is allowed to test?

The EPA's table for renovations is short: test kits are used by certified renovators; X-ray fluorescence instruments by certified lead inspectors or risk assessors; paint chip samples by a certified renovator, inspector or risk assessor. Whatever method is chosen, it must cover every surface the work will affect.

In Pennsylvania, inspectors and risk assessors are certified by the state. The Department of Health says the only way to know for sure is to hire a Pennsylvania-certified inspector, that the Department of Labor and Industry publishes lists of certified firms, inspectors and risk assessors updated daily, and that these are private businesses whose fees the owner pays.

Can you ask the painter to test?

Yes. When the person paying for the job requests it, the EPA says the certified renovator must test with an EPA-recognized kit or collect paint chip samples for a recognized laboratory. If the painter does test, the federal recordkeeping rule requires a record of the kit's manufacturer and model, the components tested and their locations, and each result, and the firm must give you that information after the job, with the final invoice or within 30 days.

What about testing after the work?

That is a separate option, and one you can write into the contract. Normally a certified renovator checks the cleanup by wiping sills and floors and comparing the cloths with a card. The federal rule allows dust clearance testing instead, by a certified inspector, risk assessor or dust sampling technician, when the contract requires it, with the firm re-cleaning until the samples fall below the dust-lead action levels. For do-it-yourself work, the EPA says you can hire a certified dust sampling technician, inspector or risk assessor to do post-renovation dust-lead testing.

When is testing most worth it?

The sources point to a few situations.

• Young children or a pregnant woman in the home. The CDC advises asking your state or local health department about testing paint and dust in a pre-1978 home, and keeping children away from peeling paint.
• Peeling or chipping paint. The EPA says deteriorating lead paint may need immediate attention from a certified lead professional.
• Buying a house. Under federal disclosure rules, buyers of most pre-1978 homes get a 10-day period to have an inspection or risk assessment done, which they may waive.
• A large job. If testing shows that the components a job will touch are lead-free, those components fall outside the rule.

Can testing be free?

For some families. If a child's blood lead level is 3.5 micrograms per deciliter or higher, Delaware County says the home can now get a free lead inspection under a statewide program. In Philadelphia, the Lead and Healthy Homes Program sends a licensed inspector to test every painted surface in such a home at no charge. Montgomery County's Lead Hazard Control Program tests and repairs eligible pre-1978 homes where a child under 6 lives or visits or a pregnant woman lives, within income limits. For children themselves, the CDC says a blood lead test is the best way to tell whether they have been exposed.

None of the cost surveys used for these guides publishes a price for a lead inspection, so ask for a written quote. The lead rule for older homes explains what a painter must do when no test is done, and what Pennsylvania requires covers state certification. Painters are on the painters directory page.
