Lead testing in Manhattan.

What lead testing looks like in Manhattan.

Manhattan's pre-war housing carries the highest concentration of lead-painted surfaces in the city. Envirex runs XRF surveys, dust-wipe clearance and HPD lead violation work across every Manhattan neighborhood — from Inwood to the Financial District.

For an Envirex engagement in Manhattan, 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 Manhattan.

Manhattan's lead-testing volume is concentrated in three building types: pre-war co-ops and condos with original window assemblies (the Upper East Side, Upper West Side, Park Avenue corridor), brownstones with multiple paint generations, and institutional buildings — schools, hospitals, religious — that require HUD-protocol inspections. Each calls for a different XRF survey approach. Co-op friction-surface work is component-heavy; brownstone work involves layer-by-layer analysis; institutional work requires HUD-grade documentation.

What we typically find in Manhattan.

In our Manhattan field work, friction surfaces — window stools, troughs, sashes and jambs — are the most consistently lead-positive components, with detection rates above 85% in pre-1960 stock. Decorative trim with multiple paint layers (crown molding, baseboards, plinth blocks) is a close second. We routinely find inconclusive XRF readings on layered trim that require paint-chip confirmation. Same-day field summaries help co-op boards and managing agents scope follow-on remediation quickly.

Where demand concentrates in Manhattan.

Demand concentrates in Upper East Side and Upper West Side pre-war buildings (annual LL1 cycle plus pre-renovation surveys), Harlem brownstones (often under HPD oversight), and Financial District residential conversions of pre-1960 commercial buildings. Midtown commercial conversions and West Village townhouses round out the bulk of our Manhattan lead-testing schedule.
