Bluefin Plumbing Inc. in Chula Vista holds CSLB license #1136494 under the C-36 plumbing classification, with a $25,000 contractor's bond through Nationwide Mutual Insurance Company. Founded in 2025, the operation provides residential and commercial plumbing from Fifth Avenue in the 91910 ZIP, and exterior plumbing work on irrigation supply lines and drainage systems coordinates with the hardscape and retaining-wall projects Southwest Boulder & Stone supplies material for across Chula Vista. The service menu covers emergency pipe repair, drain cleaning, water heater installation, bathroom remodel plumbing, fixture replacement, and preventative maintenance contracts for residential and commercial accounts. Interior bathroom-remodel plumbing — including shower-valve rough-in, supply relocation, and drain repositioning — precedes the tile, drywall, and finish work that Repairs and Remodels on Demand completes on the same renovation timelines. Whole-house repiping projects replace corroded galvanized steel or degraded polybutylene supply lines with Type L copper or PEX-A tubing manifolded to individual fixture runs, pressure-tested to 150 PSI per California Plumbing Code before wall closure.
