Haugen Plumbing, Inc. in Carlsbad Village holds CSLB license #870118 with C-36 plumbing and B general building classifications, serving residential and commercial clients from a Carlsbad Village Drive address since 2005. The electronic leak detection program uses acoustic amplification and thermal imaging equipment to pinpoint slab leaks beneath concrete foundations without exploratory demolition — an investigative step that often precedes water damage remediation by Tamarack Restoration on the same property. Core residential services in the 92008 zip code include copper repipes, gas line installation, pressure regulator replacement, and reverse osmosis system installation for the hard-water conditions common west of El Camino Real. Walk-in consultations at the Carlsbad Village Drive office near the Carlsbad Farmers Market allow homeowners to schedule leak inspections and water heater replacements for Village-area properties. Irrigation repair and backflow prevention testing extend the service menu into outdoor plumbing — work that runs parallel to Victory Sprinkler on North County residential irrigation projects. The highest-complexity offering involves full-home manifold repipes with dedicated hot and cold PEX-B home-run lines from a centralized distribution manifold, eliminating daisy-chained trunk-and-branch systems in pre-1990 Carlsbad construction.
