Founded in 1914 and operating under CSLB #877814, Powers Plumbing works out of its 1923 Mission Hills headquarters at 1705 West Lewis Street, a building on the Fort Stockton Trolley Line Historic District register. Trenchless cured-in-place pipe lining is the signature service, replacing Orangeburg and clay laterals under driveways without open excavation — a technique routinely applied to the century-old Mission Hills bungalows where CET Electric gets pulled under NEC 250.104 to re-establish the equipment grounding path after a copper water main is cut and replaced and the main bonding jumper has to be re-landed. Whole-house repipes on galvanized-to-copper conversions dominate the bungalow stock, exposing cast-iron DWV that needs replacement inside the same wall openings before drywall closeout. Tankless water heater conversions, gas-line reroutes, and whole-home water filtration round out the residential menu. Historic-review renovation work on Mission Hills single-family properties opens plumbing rough-in scopes where the single-contract architecture-interiors-construction delivery model at Keith Roberti Design, Build, Project Management keeps Powers on one unified schedule rather than chasing separate architect, GC, and sub timelines through the Uptown historic approval track. The most demanding job on the calendar is a full trenchless sewer lateral replacement under the concrete driveways and heritage hardscape of a Mission Hills historic-review property, completed with city lateral tie-in and no driveway demolition.
