You cannot confirm or rule out lead paint by its color, texture, or a photograph. If your home was built before 1978, consider lead before disturbing old painted surfaces. A certified lead-based paint inspection or risk assessment can answer different questions that a consumer swab alone cannot.
Start with the question you need answered: does a surface contain lead-based paint, is there a current exposure hazard, or how should a planned renovation be handled? Tell the professional which decision you are trying to make.
Why an older home deserves attention
EPA’s exposure guidance identifies pre-1978 homes as more likely to contain lead-based paint. Dust and chips can come from deteriorating paint, friction at windows and doors, or renovation. Paint that looks intact does not prove there is no lead underneath it.
Before sanding, drilling, scraping, or replacing old painted trim, pause and arrange appropriate assessment. Keep children away from peeling paint and work debris. Do not begin a project by cutting into layers simply to see what is there.
What home test kits can and cannot tell you
A surface test can offer limited information when used for its intended purpose. It is not a whole-house clearance, a dust assessment, or a blood test. Results depend on the kit, material, procedure, and interpretation.
EPA’s recognized-kit guidance describes specific substrates and trained professional use under the Renovation, Repair and Painting rule. A marketplace claim that a swab detects lead is not the same as recognition for a particular regulatory use.
There is also a product-name update: after 3M stopped making LeadCheck, the formulation and trademarks transferred to Luxfer Magtech in 2024. EPA describes its continued recognition under the specified professional-use conditions. Check current packaging, shelf life, and instructions rather than relying on an old product roundup or an unfamiliar replacement listing.
Inspection and risk assessment answer different questions
A lead-based paint inspection identifies lead-based paint. A risk assessment evaluates lead hazards and recommends ways to address them. Depending on the situation, the assessment can involve more than a painted wall.
EPA explains the certification framework for these services and for abatement. Ask what the proposed service includes, what methods will be used, and what written results you will receive. Do not assume a standard home inspection includes this specialized work.
Renovation credentials are not the same as abatement credentials
Lead-safe renovation practices address paint disturbance during covered renovation work. Abatement is work intended to permanently eliminate lead-based paint hazards. A firm’s renovation credential should not be treated as proof it is qualified for every abatement or assessment task.
Ask the state lead program or qualified professional which certification applies to your project. Describe whether you are maintaining a home, renovating, renting it out, or arranging hazard removal. Those circumstances can affect the requirements.
What changed in 2026?
EPA’s revised dust-lead rule includes provisions with a January 12, 2026 compliance date in EPA-administered jurisdictions. EPA’s date guidance makes that jurisdiction distinction explicit. These standards concern professional dust reporting and abatement processes; they do not turn a paint swab into a dust-clearance test.
If you are comparing reports or planning work, ask which current standards and program apply locally. For concerns about a person’s exposure, contact a healthcare professional or local health department. A paint-test result cannot diagnose lead poisoning.
