Holding dual CSLB licenses — #831318 for C-36 plumbing and #1107759 for electrical — Almighty Services operates from Avocado Boulevard in La Mesa's Casa de Oro district, a combined-trade capability uncommon among single-shop plumbing contractors. Water-heater replacements frequently require both gas-line resizing and 240-volt circuit installation for hybrid heat-pump units, a dual-permit workflow that parallels the mechanical-electrical coordination performed by HVAC contractors such as Jackson & Foster Heating and Air Conditioning. Founded in 1995, the firm specializes in tankless water-heater conversions — including gas-line upsizing from 1/2-inch to 3/4-inch supply, Category III stainless-steel venting, and condensate-drain routing per California Plumbing Code Section 510. Whole-house copper-to-PEX repipe projects that expose wall cavities for new manifold runs often require post-completion drywall finishing and exterior touch-up through painting contractors like Advanced Exteriors | Rhino Shield of San Diego. Highest-value installations involve multi-point tankless cascade systems supplying simultaneous domestic hot water and hydronic radiant-floor loops across two-story hillside residences in the Mt Helix area.
