Lead Testing and Removal FAQs, answered by experts

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.

While not all homes built before 1978 contain lead paint, enough do, so you’ll still want to test to be on the safe side. The federal government banned lead-based paint for homes in 1978, but your state may have banned lead before that time. Around 24% of homes built between 1960 and 1977 contained lead-based paint, while 87% of homes built before 1940 contained lead-based paint.

At-home lead tests can provide accurate results if used correctly, and if the kits are reputable and certified. They vary in sensitivity and methodology, influencing their accuracy. Follow instructions meticulously, ensuring proper sample collection and test execution. While they can detect elevated lead levels, for precise confirmation or if results are concerning, consider professional testing or lab analysis for comprehensive accuracy and guidance on addressing any issues.

According to the EPA, there is no safe level of lead in the blood, and so the maximum contaminant level goal (MCLG) for lead in water is zero. Even at low levels, lead is harmful to human health. It can also remain in the body and build up over time with repeated exposure.

Professional lead removal involves identifying and safely removing or encapsulating lead-based paints and materials, using specialized equipment, and following strict safety procedures to minimize exposure and contamination.
