Lead Testing and Removal FAQs, answered by experts

Lead removal is crucial in older homes to eliminate risks of lead poisoning, which can severely affect health, particularly in children, by impacting development and cognitive functions.

The average cost of a lead paint inspection is about $600, but it can cost as low as $150 or as much as $800, depending on the size of the area, geographic location, and the inspection methods. Some of the most common lead paint inspection methods include:

  • Visual inspection: $150–$400

  • Paint sampling: $200–$600

  • X-ray fluorescence (XRF): $250–$700

  • Risk assessment: $300–$800

Several different measurements may be used to determine the amount of lead in water. The most common unit of measurement is micrograms per liter (µg/L), which is the same as parts per billion. Another measurement is milligrams per liter (mg/L), which is the same as parts per million.

If lead is detected in a property, steps should include arranging for professional removal or containment, notifying all occupants, and implementing interim safety measures to reduce exposure.

Mold, VOCs, radon, carbon monoxide, and particulate matter are typically measured.
