Lead testing in Westchester County.

What lead testing looks like in Westchester County.

Westchester's pre-1960 housing concentrates in Yonkers, Mount Vernon, New Rochelle and White Plains — Envirex's heaviest lead testing volume north of NYC. Estate-class properties in Bedford, Scarsdale and Chappaqua draw mold, IAQ and Phase I work.

For an Envirex engagement in Westchester County, 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 Westchester County.

Westchester County lead-testing engagements split between three markets: pre-1960 multifamily and row-house stock in Yonkers, Mount Vernon, New Rochelle and Port Chester (functionally similar to Bronx multifamily); estate-class single-family homes in Bedford, Scarsdale, Chappaqua and Larchmont (deep paint history, ornate trim); and pre-purchase diligence work across the county. Each market calls for a different scope cadence.

What we typically find in Westchester County.

Yonkers and Mount Vernon walk-ups follow the dense pre-1960 NYC pattern. Bedford and Scarsdale estates often have 6–10 paint layers on original wood trim, requiring chip sampling on most inconclusive XRF readings. Mid-county properties in Tarrytown, Sleepy Hollow and Ossining show a mix — original pre-war stock plus mid-century additions, with mixed lead patterns by component.

Where demand concentrates in Westchester County.

Yonkers, Mount Vernon, New Rochelle and Port Chester drive the multifamily and HPD-equivalent lead work. Bedford, Scarsdale, Chappaqua, Larchmont, Bronxville and Pelham draw estate-class engagements. Pre-purchase diligence comes from across the county but concentrates in Greenwich-adjacent Rye, Harrison and Mamaroneck.
