Colepepper Plumbing in downtown San Diego's Middletown district carries CSLB license #999813 in C-36 Plumbing and C-20 Warm-Air Heating, Ventilating and Air Conditioning classifications, operating from State Street as a third-generation plumbing practice since 2003. Wall-cavity pipe access during slab-leak detection and re-piping frequently reveals termite damage behind drywall, triggering coordinated inspections with pest control operators including Kilter Termite and Pest Control in Middletown. Services span drain cleaning, hydro-jetting, sewer camera inspection, tankless and tank water heater installation, whole-house copper and PEX re-piping, water filtration systems, mini-split HVAC installation, and slab-leak repair. Electrical coordination on tankless water heater upgrades and mini-split installations brings the crew alongside All City Electric, Inc. in Bankers Hill for panel upgrades and dedicated circuit runs. The most involved projects are whole-house re-pipes of pre-1970 galvanized systems, requiring sequential room-by-room pipe replacement, drywall patching, and pressure testing across every fixture in the building.
