Core Resource Services LLC is a licensed California contractor based in Corona, Riverside County, holding CSLB license #1122300 under classification A — General Engineering, C31 Construction Zone Traffic Control, C49 Tree and Palm. The license was active and clear when this listing was compiled.
Tree work covers removal, trimming and crown reduction, stump grinding, deadwooding, storm damage response, and clearance pruning away from structures, lines and driveways.
Working in the Inland Empire: Expansive clay soils are common across the inland valleys, and they move enough with the seasons to matter for foundations, flatwork and anything tied to them.
Before you hire any tree service: Ask what is included: haul-away of the wood and chips, stump grinding, and how deep. Stump grinding depth and debris removal are the two items most often left out of a low quote.
License status can change at any time. Confirm license #1122300 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
