Sessler Environmental Services

What Sessler Environmental Services does

Sessler Environmental Services (SES) is a privately held, multi-disciplinary specialty environmental contractor operating across New York State and the broader Northeast, Mid-Atlantic, and Great Lakes regions. The company delivers seven core service lines: asbestos abatement, environmental remediation, industrial cleaning, interior and select demolition, environmental investigation, decommissioning/decontamination/demolition, and concrete saw cutting and removal. Its technical capability is anchored in specialized physical equipment, including GPS-guided excavation systems, 110,000 CFM HEPA-filtered negative air machines, mobile personnel decontamination units, slide rail shoring systems for excavations up to 15 feet below grade, temporary water treatment systems, and odor suppression equipment. Project scale is substantial for a specialty contractor, evidenced by completed abatement of 1,150 tons of friable and 3,700 tons of non-friable asbestos on a single power plant project and segregation of 17,000+ tons of impacted soils on a petroleum facility cleanup.

SES generates revenue through project-based, lump-sum and competitively bid contracts across four primary customer segments: government entities (federal, state, and municipal), industrial and manufacturing facilities, educational institutions, and commercial/real estate developers. The go-to-market model relies on enterprise field sales pursuing public procurement (RFPs) and direct private-sector engagement, supported by an extensive safety track record (450,000+ man-hours across 28 consecutive months without lost workday cases) and certifications including NYS Asbestos License, EPA Lead Certified, HAZWOPER, and ISNET World membership. The company maintains four offices (Macedon HQ, Oriskany, Owego, East Syracuse), expanded its geographic reach through the June 2024 acquisition of O'Rourke Incorporated's construction division, and is consistently ranked in the Engineering News-Record Top 200 Environmental Firms and Top Specialty Contractors lists. SES operates as part of Sessler Companies, a generational family-owned enterprise established in 1958.

Broad incumbents

• Clean Harbors: Publicly traded (CLH) environmental and industrial services giant offering hazardous waste management, remediation, and industrial cleaning across North America. A scaled incumbent in SES's end markets, though SES operates as a regionally focused specialty contractor rather than full-service waste disposal operator.
• Republic Services: Large publicly traded (RSG) environmental services company focused on solid waste and recycling. Provides environmental remediation and industrial services as part of its broader portfolio, serving as an incumbent with deeper capital and geographic reach.
• Stericycle: Publicly traded regulated waste and compliance services provider. Overlaps with SES on hazardous waste handling and remediation, though Stericycle's core franchise is medical waste and regulated waste pickup rather than abatement/demolition.
• Veolia North America: Global environmental services giant operating hazardous waste treatment, industrial services, and remediation in the US. Operates as a broad incumbent with significant remediation capabilities overlapping SES's core work.
• GHD (Environmental & Remediation Practice): Global engineering and environmental consulting firm with remediation, compliance, and site investigation practices. Comparable on the environmental investigation and compliance consulting side, though primarily a consultancy rather than a contractor.
