Torrance is one of the South Bay’s largest and most varied cities — historic Old Torrance homes, postwar tract neighborhoods, condo communities, and major commercial and industrial corridors. That diversity means the construction work here spans the full range: vintage homes needing repipes and sewer work, tract houses ready for kitchen and bath remodels, and businesses needing tenant improvements in office, retail, and industrial buildings. It’s a city where a contractor’s range matters — the same company should be able to handle a historic home’s plumbing, a family’s addition, and a commercial build-out, because Torrance property owners need all three.
Mars Construction Industries Corp is a multi-trade general contractor based in Orange, CA, operating with 30+ years of hands-on experience. We hold four CSLB licenses in-house — A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC (CSLB #1138550). One accountable team handles your construction, plumbing, drain and sewer work, and HVAC under a single contract — residential or commercial.
Construction & Remodeling Services in Torrance, CA
Our Torrance residential work covers the city’s housing range. In Old Torrance and the older neighborhoods, we perform repipes, water heater replacements, and gas line work — in-house under our C-36 license — paired with kitchen and bathroom remodels so infrastructure and finishes move as one project. In the tract neighborhoods, we focus on kitchen and bath renovations, room additions, and whole-home updates. Our drain and sewer services — camera inspection, hydro jetting, trenchless repair — come with a 20-year warranty on sewer lining, protecting homeowners from the disruption of digging up a failed lateral.
HVAC is a steady need across the city: we install, replace, and repair air conditioning and heating systems for homes of every era. And ADUs are a strong fit for Torrance lots — through our sister brand ADU Cities, we’ve built more than 100 ADUs in four years, giving families flexible space for relatives or long-term use.
On the commercial side, Torrance’s business corridors keep us busy with tenant improvement: office build-outs, retail and restaurant TI, and industrial building improvements. Because we hold plumbing and HVAC licenses in-house, a commercial project that needs restroom build-outs, process plumbing, or rooftop HVAC stays under one contract with one team accountable for the schedule.
