We are California MBE/DBE General Contractors with decades of experience in the management and remediation of HAZMAT, heavy metals, carcinogenic substances, hazardous waste, RCRA, contaminated soils, and VOCs (Volatile Organic Compounds).
We have a wider range of licenses than any contractor in the state, giving us experience over all scopes of work related to HAZMAT, acutely toxic environments, radioactive substances, earthwork and excavation, general engineering and hillside reinforcement, groundwater treatments, and more. This includes the rare AQMD-1166 Various Sites license for contaminated soil management across the state.
We and our partners have decades of experience in the safe removal of USTs, especially during our demolition work and contaminated soil removal work. This includes comprehensive permitting work, PID monitoring and vapor suppression with dry ice, soil testing and hauling of leaked contaminants and soil, and certification by Industrial Hygenists. We have a full HAZWOPER-certified labor force that is respirator fit-tested and prepped for confined space work and tank cleaning, degassing, and more for oxygen-deficient environments or those with acutely toxic gasses. This range of scopes makes us one of the most comprehensive HAZMAT companies in the state.
Aside from our wider range of licenses, we outmuscle out competitors because they tend to be *environmental companies,* not *HAZMAT* engineers. This means your “HAZMAT experts” will be scientists and technicians with only recent science degrees from universities, but little to no field experience in construction projects, little to no direct experience in earthwork or engineering, and little to no knowledge in HAZMAT. Environmental companies are almost never licensed to actually work with HAZMAT!
This makes Mayfield your ideal partners for any hazardous environment: we combine environmental skills with HAZMAT, and engineering with construction and earthwork. We also have the unique status of being MBE (Minority-owned), Disadvantaged (DBE), Small Business, Public Works, Tribal/Native American, and Federal Contractors, which makes us your key ally for bidding and navigating the many agencies involved in any complex demo project, whether it is AQMD, DTSC, EPA, Coastal Commission, tribal governments, and more.
