Masek Consulting Services

What Masek Consulting Services does

Masek Consulting Services, Inc. is a privately held environmental consulting firm founded in 1992 by Stephen Masek and headquartered in Mission Viejo, California. The firm provides project-based professional consulting services for hazardous materials assessment and abatement oversight — specifically asbestos surveys, lead-based paint inspections using Thermo Niton X-Ray Fluorescence (XRF) analyzers, mold and indoor air quality investigations using battery-powered air pumps, PCB surveys, Phase I and II Environmental Site Assessments, property and building condition assessments performed to the ASTM E2018 standard, universal waste surveys, and LEED accreditation consulting. Fieldwork is delivered by senior experienced consultants (rather than delegated to junior staff), and reports are written by the consultants who performed the inspections — a quality-control model the firm uses as its primary differentiator against larger consultancies.

The firm's revenue model is professional-services fees billed on a per-project basis, with multi-year contracts and competitive-bid wins (including 11 contracts with Caltrans covering 716 buildings). Pricing is not publicly disclosed; the firm positions itself as 'high quality at a low price' relative to larger environmental consultancies, claiming to keep overhead low while investing in top-quality testing instruments. Customers span federal/state/municipal government (California DOT, Navy installations, school districts, cities of Ontario and Oceanside), healthcare (Pacifica Hospital, Queen of Angels/Hollywood Presbyterian), banking (Wells Fargo, 29 branches across five states), telecommunications carriers (AT&T, T-Mobile, Sprint, Nextel), retail, defense redevelopment (former Norton AFB, MCAS El Toro), and other consulting firms subcontracting for specialized expertise.

Distribution is direct, relationship-driven, and geography-centered on California with multi-state reach for specific enterprise engagements. The firm maintains a content-marketing website with detailed project case studies, plus minimal social presences on Facebook and LinkedIn via the founder's profile. Stephen Masek, the founder, drafted portions of the original ASTM E2018 Property Condition Assessment standard (1999), representing standards-level technical authority in the firm's core service line.
