Lead Testing and Removal questions, answered by experts

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

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.

Testing typically costs between $200 and $600, depending on the number of samples and laboratory analysis.

A professional indoor air quality inspection takes anywhere from one to three hours, depending on the size of your home and the number of necessary samples. After the test, the specialist will discuss the findings, but you won’t get a full written report for 2 to 10 days, though you can ask your pro to expedite the process, if needed. 

DIY lead testing kits are available, but they often lack the accuracy and reliability of professional services. Professional testing is recommended for more accurate results, as properly certified testers can provide a thorough analysis, clear recommendations, and the necessary legal documentation if remediation is required.
