Lead Testing and Removal questions, answered by experts

You can sell a house with lead paint, but there are several requirements. If you are aware that lead paint exists anywhere in the home, you must disclose that to potential buyers. Required home inspections will often uncover lead paint, especially for older houses where lead paint may still be a problem. If you have taken steps to encapsulate lead, you should provide buyers with full documentation of the project so it won’t cause any problems later on.

DIY kits are available for basic air quality testing, but professional services provide more comprehensive results and recommendations. While a DIY kit may seem cost-effective, a professional assessment is more thorough. Inspectors are better equipped to catch all pollutants and hazards, and you'll still need a professional to verify and act on DIY test results. Furthermore, some kits don't test for certain pollutants or only detect their presence without measuring specific levels (like mold spores). It's generally better to opt for a detailed professional assessment.

Results from professional lead testing are typically available within a few days to a week (2-7 days), depending on factors like laboratory processing times and the volume of samples being analyzed. Expedited services may also be available for urgent situations.

Professional testing for lead paint costs about $300, ranging from about $250 to $700, depending on the square footage, accessibility, and location. However, testing for lead paint with a DIY home-testing kit costs about $25, but doesn’t guarantee accurate results. The U.S. Environmental Protection Agency (EPA) recommends using a lead test kit that complies with the Lead Renovation, Repair, and Painting (RRP) Rule, which has strict criteria for ensuring a more accurate reading.

Common home surfaces to test for lead include:

  • Walls

  • Windows

  • Doors

  • Molding and trim

  • Railings

Costs depend on the number of samples, testing method, lab fees, and whether on-site inspections are required.
