Lead testing in Brooklyn.

What lead testing looks like in Brooklyn.

Brooklyn's brownstone belt — Bed-Stuy, Crown Heights, Park Slope, Fort Greene — is HPD lead violation territory. Envirex closes Class C violations end-to-end, from dispatch through certification of correction.

For an Envirex engagement in Brooklyn, our scope of work typically includes:

• XRF Inspections. Non-destructive, surface-by-surface identification of lead in paint. The industry standard for Local Law 1, Local Law 31 and pre-abatement scoping. See XRF Inspections.
• Paint-Chip Sampling. Lab-confirmed lead in paint, where XRF is inconclusive or where a court / lender requires destructive verification. AIHA-LAP analysis. See Paint Chip Sampling.
• Dust-Wipe Clearance. Standardized wipe sampling to verify a renovated or abated space is lead-safe — to current EPA thresholds. See Dust Wipe Clearance.
• Lead in Water. First-draw and flushed sampling at the tap, fixture-by-fixture, for schools, child-care, co-ops and condos. See Lead in Water.
• Lead in Soil. Discrete or composite soil sampling for properties with exterior-paint, gasoline-era or industrial lead exposure history. See Lead in Soil.

Building stock and project patterns in Brooklyn.

Brooklyn's lead-testing engagements split between three categories: pre-1900 brownstones (Park Slope, Brooklyn Heights, Bed-Stuy, Crown Heights, Fort Greene), 4–6 story walk-up multifamily (Bay Ridge, Bensonhurst, Sunset Park, Flatbush), and post-2000 loft and condo conversions in DUMBO, Williamsburg and Long Island City–adjacent neighborhoods. Brownstone work is component-rich and time-intensive; walk-up multifamily work is volume-driven, often portfolio-wide.

What we typically find in Brooklyn.

The signature Brooklyn finding is original brownstone interior trim — door surrounds, baseboards, plaster ceiling medallions — bearing multiple paint generations, the deepest of which is lead-positive. In walk-ups, window jambs and door frames in common-area hallways are consistently positive. Where one party-wall side has been renovated and the other hasn't, the paint-layer transition is a frequent XRF inconclusive that we resolve with chip sampling.

Where demand concentrates in Brooklyn.

HPD-driven testing is heaviest in Bed-Stuy, Crown Heights, Bushwick and East New York. Owner-initiated pre-renovation and pre-purchase surveys cluster in Park Slope, Brooklyn Heights, Fort Greene, Carroll Gardens and Cobble Hill. Multifamily portfolio testing runs heaviest across Sunset Park, Flatbush and Bensonhurst.
