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).

Mayfield is ready to help consult with all your complex HAZMAT issues, lawsuits, insurance claims, compliance concerns, case studies, environmental impact assessments, and more. Give Mayfield’s HAZMAT engineers, Industrial Hygienists, Biohazard professionals, and scientists a call so we can help keep your business compliant and keep your neighborhood safe.

We have a wider range of licenses than any contractor in the state, giving us experience over all scopes of work related to HAZMAT, Biohazard, 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.

For two generations, we have provided expertise and solutions to the impacts of HAZMAT related to wildfire disasters (Camp Fire, Lahaina, Palisades), contamination from Superfund/CRCLA sites and Brownfields, assessing community health impacts from chemical leaks and HAZMAT spills (GKN Aerospace Garden Grove, Exide Superfund), community respiratory hazards from warehouse fires (Lineage Warehouse), demolition of 100s of toxic structures in the Palisades/Eaton Fire and decontaminating over 3,000 properties, remediating and demolishing entire city blocks (Arcata, CA 2026), protecting sensitive waterways and oak groves and estuaries from pesticide and toxic runoff, and so much more.

Aside from our wider range of licenses, we outmuscle out competitors because they tend to be *environmental companies* or Industrial Hygienists with very little training; 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.

We are also unique in our ability to provide expert consultation and remediation guidance for obscure and dangerous chemicals and hazardous substances, including creosote, pesticides, organophosphates, beryllium, hexavalent chromium, and more.
