How to Use This Calculator

Enter Affected area (sq ft) and Paint layers — pre-1978 buildings typically have 5–20 layers of lead-containing paint.
Select Method (0=Encapsulation, 1=Chemical strip, 2=Mechanical removal, 3=Full abatement) based on substrate condition and preservation goals.
Toggle Interior (1=yes) to add containment costs; exterior work typically requires less containment equipment.
Review Total cost and Treatment cost to plan the lead abatement budget and select a licensed contractor.
Check Preservation impact (0=None to 3=Severe) — encapsulation has no impact while full abatement may damage historic fabric.
Use Cost per sq ft to compare lead management strategies and discuss the best approach with your preservation architect.
