What Environmental Testing & Technology, Inc. does

Environmental Testing & Technology, Inc. (ET&T) is a privately held environmental testing and indoor air quality consulting firm founded in 1986 and headquartered in Encinitas, California, with a secondary office in Vista. The company provides professional inspection and testing services for residential and commercial properties, with core offerings spanning mold testing and post-remediation verification, comprehensive indoor air quality surveys, EMF/RF surveys, asbestos and lead testing, moisture mapping, building diagnostics and construction defect investigations, infection prevention consulting, and litigation support/expert witness services. ET&T differentiates on third-party independence (it does not perform remediation), state-level certifications (California Certified Asbestos Consultant, Lead Inspector/Assessor, CMC, CMI), and state-of-the-art on-site instrumentation including the Narda SRM 3006 spectrum analyzer for RF measurements and sensitive hydrogen sulfide monitoring devices, supplemented by access to accredited analytical laboratories for specialized testing.

The company serves a horizontal mix of customers — homeowners, residential property owners, hotels, biotech firms, restaurants, hospitals, schools, prisons, museums, water districts, and law firms — with a heavy concentration in Southern California (San Diego County and surrounding areas) and project reach extending through an affiliated-expert network across the United States, Canada, and Europe. The business model is project-based professional services with free initial phone consultations; most engagements are quote-based per project, with select services such as remote 24-hour EMF data logging priced on a usage basis (an introductory $350 rate). Customer acquisition relies on local SEO, location-specific service pages, blog content authored by principals, and referrals from legal, insurance, real estate, and government channels.

ET&T is a small, founder-led operation (reported headcount of 5) with Peter Sierck serving as President and Felix Neumann as Mold Consultant and IICRC-approved AMRT instructor. The firm has no disclosed institutional investors, no funding rounds, no subsidiaries, and no parent company. Strategic activity over the past decade has centered on incremental service-line extensions (infection prevention, training courses) and selective partnerships (Cuprotect for RF shielding) rather than on scaling, geographic expansion beyond Southern California, or technology platform development.
