What this license means

Before you hire Environmental Support Technologies
-
Confirm the record on the official site
Our copy is from the state's file dated November 6, 2026. The official record is live and also lists complaints and discipline, which our data doesn't include.
-
Make sure the name on the contract matches
The contract, the permit and the license should all name Environmental Support Technologies or Advanced Environmental Group INC. A different company name on the paperwork usually means someone else is working under this license.
-
Check the license covers your job
This is a general engineering (a), well drilling (c-57) and 1 more license. If your job is a different trade, the contractor needs that license too, or a licensed sub for that part.
Is this your license, or is something wrong?
This status comes from California Contractors State License Board's License Master file, file dated November 6, 2026, and it may have changed since. The official record is the one that counts. If it's wrong, the state has to fix it. If our page is the problem, or you want this record off our site, email us or see our corrections page.
