Allegiance General Contractor & Plumbing, Inc. on El Cajon Boulevard in La Mesa holds dual CSLB licensing—a Class B General Building credential and a C-36 Plumbing classification—allowing a single-contractor scope that eliminates subcontractor coordination on combined remodel-and-plumbing projects. The company was founded in 2019 and carries a BBB A+ accreditation, with project scope spanning water heater replacements, whole-house repiping, kitchen and bathroom remodels, and the interior finish work that follows the wall-texture and coating application by High-Point Painting. The dual-license structure means a single permit holder manages both the rough plumbing and the general construction framing, drywall, and finish phases, reducing inspection scheduling conflicts that delay La Mesa remodeling timelines. Gas-line repair and new gas-line installation fall under the C-36 scope, and the company's general-building authority extends to structural modifications like load-bearing wall removal, a demolition phase that often exposes the supply-line routing reconfigured alongside fixture upgrades sourced through Damman's Plumbing. Full-scope bathroom remodels require coordinated rough plumbing relocation, structural framing modification, waterproof membrane installation, and finish-tile setting under a single general-building permit.
