Internal Systems Drywall and Plaster Contractor

Internal Systems at P O BOX 1056, Grover City, CA 93433, held a Drywall and Plaster Contractor license (#379141) with the California contractors license board with an expiration date of 08-31-1981. We last verified the license was expired on 05-21-2026.

Their BuildZoom score is 0 because we haven’t been able to verify an active license. As a result, they’re not ranked in the top 50% of 336,931 California contractors.

If you’re thinking about hiring them, we recommend double-checking their license status with your local licensing authority. Alternatively, use our project planner to be easily matched to qualified, licensed professionals in your area.
