One Negative Swab and a Whole-House Claim
A 1965 single-family home will get six interior doors and one bay window replaced. Before work, a certified renovator uses an EPA-recognized test kit on one door jamb and one window sill. Both tests are negative. The owner tells the renovator to skip lead-safe practices for the rest of the house because 'the kit proved there is no lead paint.' One of the doors has peeling paint, and the bay window has chalky paint that the renovator says cannot be tested reliably. The renovator tested only the top layer of paint on the sill. No paint-chip laboratory analysis or XRF inspection was performed. The renovator plans to note 'no LBP' on the file and proceed. The owner also wants a letter stating the entire house is lead-free for a future sale.
1. Can the two negative kit results support the owner's conclusion that the whole house is free of lead-based paint? Explain the scope and limits of EPA-recognized test kits under the RRP Rule.

No. The results are component-specific, and two negative swabs do not establish that the house is free of lead-based paint.
An EPA-recognized test kit may be used by a certified renovator to determine whether a specific component that will be disturbed contains lead-based paint. The kit must be on EPA's recognized list and must be used according to the manufacturer's instructions. A negative result for one door jamb says nothing about the other five doors, the bay window, the walls, or the trim. The renovator also tested only the top layer of paint; if lower layers contain lead, a top-layer-only negative can be misleading. Test kits are not reliable on deteriorated, peeling, or chalky paint, and the instructions may prohibit their use on such surfaces. The correct response is to test each component that will be disturbed, presume lead-based paint where testing is unreliable, or use laboratory analysis or a certified inspector.
2. What should the renovator do about the peeling door and the chalky bay window before deciding whether RRP work practices apply?
Read the worked answer
The renovator should not use the test kit on the peeling door or the chalky bay window as if the result were reliable.
For those surfaces, the renovator should either presume that lead-based paint is present and use lead-safe work practices, or have the paint tested by a laboratory or by a certified inspector or risk assessor using acceptable methods. If a paint chip is collected, it must be analyzed by an accredited laboratory. The renovator should also follow the test kit instructions for the other components; if the instructions require exposing all paint layers or prohibit testing certain substrates, those limits must be respected. The file should record which components were tested, the kit used, the results, and which components were presumed to contain lead-based paint. A blanket 'no LBP' note is not supported.
3. If the owner insists on a whole-house 'lead-free' letter, who is authorized to make that determination and what does it require?
Read the worked answer
A certified renovator cannot issue a whole-house lead-free determination. That requires a lead-based paint inspection performed by a certified lead-based paint inspector, using XRF and/or laboratory analysis of paint samples, following the applicable inspection protocol. An inspection determines the presence or absence of lead-based paint on the components tested; it is not the same as a risk assessment, which evaluates lead hazards such as deteriorated paint, dust, and soil.
The owner should be told that a renovator's test kit results are not a substitute for an inspection. If the state has an authorized program, the inspector must hold the state credential, and the report must meet state requirements. Even a proper inspection report should be described accurately: it addresses lead-based paint on tested components, not a guarantee that the entire property has no lead in any form.
