Licensed Environmental Specialists Serving Stockton Since 2009

Certified, fully insured asbestos, lead, mold, bacteria, and indoor air quality testing — with results you can act on. We answer 24/7.

We started Cal-Environmental Testing in 2009 with a simple idea: property owners deserve accurate answers and honest guidance when a hazard is on the line. Sixteen-plus years later, that’s still how we work — we test the material, send it to an accredited lab, and sit down with the results to tell you what they actually mean for your home, your tenants, or your job site.

What drives our work

Our name goes on every report, so accuracy isn’t negotiable. Four things guide the way we operate:

Accuracy and scientific integrity. Every result is defensible. If a sample is inconclusive, we say so.
Exceptional customer service. You'll talk to a real person who explains things in plain language.
Professional expertise, always improving. Regulations and methods change; we keep up so your results hold up.
Timely, dependable results. A suspected hazard stalls a sale, a lease, or a renovation. We move quickly.

Our credentials

These aren’t just numbers on a page. The asbestos credential lets us design and oversee proper surveys and sampling; the CDPH lead license means our inspections and risk assessments meet the state’s requirements for disclosure and renovation work.

Our credentials

Homeowners buying, selling, or remodeling. Landlords and property managers meeting their obligations. General contractors who need clearance before they cut into anything. Schools, facilities, and public agencies with compliance and air-quality concerns. Residential, commercial, industrial — if there’s a question about what’s in the building, we can answer it.
