Cornerstone Construction Service INC

Based in Upland, San Bernardino County, Cornerstone Construction Service INC holds California contractor license #980455, classified B (General Building, C8 Concrete, C29 Masonry). License status at the time of compiling this listing: active, with no suspension recorded.

Concrete and masonry contractors hold C-8 or C-29 classifications, covering flatwork, foundations, retaining walls and block or stone construction.

Working in the Inland Empire: Inland Empire summers are long and hot, and Santa Ana wind events each autumn put real load on anything attached to the outside of a building.

Before you hire any concrete or masonry contractor: Ask how control joints are being placed. Concrete cracks — properly placed joints decide whether it cracks where you want it to.

License status can change at any time. Confirm license #980455 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
