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.

How the result changes with Affected area (sq ft)

Affected area (sq ft): Total area with lead paint.
Paint layers: Number of paint layers (older buildings have more).
Method (0-3): 0=Encapsulation, 1=Chemical strip, 2=Mechanical removal, 3=Full abatement.
Interior (0 or 1): 1=Interior work (higher containment cost), 0=Exterior.

Total cost ($): Total lead paint management cost including testing.
Treatment cost ($): Paint treatment/removal cost only.
Testing cost ($): XRF testing and clearance testing cost.
Preservation impact (0-3): 0=None (encapsulation), 3=Severe (full abatement).
Cost per sq ft ($): Treatment cost per square foot.

Identify Input Parameters
4 parameters
Affected area (sq ft) = 2000, Paint layers = 8, Method (0-3) = 0, Interior (0 or 1) = 1 = 4 input(s) provided
Calculate Total cost
Total cost = totalCost + testingCost + clearanceCost
10380 = $10,380
Calculate Treatment cost
Treatment cost = round(areaSqFt * costPerSf * interiorFactor)
9880 = $9,880
Calculate Testing cost
Testing cost = testPoints * 25
500 = $500
