Which method is commonly used to remediate lead hazards in homes?

Encapsulation of lead-based paint surfaces is a widely accepted method for remediating lead hazards in homes. This technique involves covering lead-containing surfaces with a protective barrier that prevents the lead from deteriorating and becoming airborne dust or chips. Encapsulation can effectively contain lead dust and prevent exposure, making it a practical choice for homes where the complete removal of lead paint may not be feasible or necessary.

In contrast, replacing windows may be effective in reducing lead exposure if old, lead-painted windows are part of the hazard. However, this approach can be costly and requires extensive labor. Applying sealants over surfaces is similar to encapsulation, but it generally does not provide the same long-term protection required for lead paint hazards and may not be suitable for all types of surfaces. Patching with drywall may address some issues related to surface integrity but does not eliminate the lead hazard itself and can leave lead in the underlying layers if not properly managed.

Therefore, encapsulation is a recognized best practice for mitigating lead exposure risks effectively while offering a manageable solution in many residential scenarios.
