When is it necessary to conduct additional lead testing?

Conducting additional lead testing is particularly important when major renovations occur or when there is a suspicion of lead hazards. This is primarily due to the potential for lead dust and chips to be disturbed during construction activities, which can significantly increase the risk of exposure to lead, especially in homes built before 1978 when lead-based paints were commonly used. It is essential to assess the environment before and after renovations to ensure that any lead hazards are identified and mitigated appropriately. Therefore, being proactive in lead testing during these times helps to protect the health and safety of occupants, particularly children and other vulnerable groups.

While selling a property may trigger certain obligations regarding lead disclosure, it does not inherently necessitate additional testing unless renovations or changes have occurred that could disturb lead-containing surfaces. Similarly, a complaint may prompt investigation but is not a definite indicator that testing is needed. The notion that there is no need for retesting overlooks the importance of actively managing potential lead risks in various situations, particularly after significant alterations to a property.
