Environmental consulting across Westchester County.
From Yonkers row-houses to Bronxville colonials and Bedford estates, Westchester's housing stock spans the full age range. Envirex schedules field crews into Westchester weekly.
Why owners in Westchester County call us.
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.
Envirex is a New York-licensed environmental firm — not a national franchise. Field crews are dispatched from our Manhattan office, and a senior project manager owns every Westchester County engagement from first call to certificate of correction.
