Fontana is a city of two eras: the historic neighborhoods near downtown, where mid-century homes sit on mature lots, and the newer tracts pushing north and west toward the foothills. That mix is exactly where a single-trade contractor falls short. An older Fontana home might need a repipe and a sewer lateral; a newer one might need a kitchen remodel or a room addition. Hiring a separate plumber, remodeler, and HVAC contractor for work on the same house is how budgets bleed.
Mars Construction Industries Corp is built for this kind of property. We hold four CSLB licenses in-house — A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC (Lic. #1138550) — so whether your project is a 1960s ranch needing its galvanized plumbing retired or a 2000s two-story needing a master-suite addition, one accountable team handles it all. In business with 30+ years of hands-on experience, with Inland Empire crews in San Bernardino County every week.
Construction & Remodeling Services in Fontana, CA
In Fontana’s older neighborhoods, the work we see most is the kind you can’t see: corroded supply lines, aging cast-iron drains, and sewer laterals that have spent decades underground. Our camera inspections show you exactly what’s happening before you spend a dollar, and when a line is failing, trenchless sewer lining — backed by a 20-year warranty — renews it without tearing up the yard. Repipes, water heaters, and gas lines all run through our own C-36 plumbing crews. In the newer tracts, the calls shift to kitchens, additions, and ADUs — and through ADU Cities (100+ built in four years) we design and build those as one package.
Fontana’s summer heat makes HVAC a headline service: our C-20 crews install and replace systems sized for real Inland Empire loads, not catalog guesses. And the logistics and warehouse corridor along the I-10/I-15 keeps our commercial division busy with office, retail, and light industrial build-outs — where having plumbing and HVAC in-house keeps the mechanical rough-in from becoming the schedule bottleneck.
- Kitchen and bathroom remodels — from builder-grade updates to full gut renovations, older ranches and newer tracts alike.
- Room additions and ADUs — growing-family additions and detached or attached ADUs via our ADU Cities team.
- Whole-home repipes — retiring aging galvanized and corroded supply lines in mid-century homes.
- Drain and sewer services — camera inspection, hydro jetting, and trenchless lining with a 20-year warranty.
- HVAC install, replacement, and repair — systems sized for Fontana’s extreme summer heat by our C-20 crews.
- Water heaters and gas lines — replacement, upgrades, and new runs by licensed C-36 plumbers.
- Commercial and tenant improvement — office, retail, and warehouse build-outs, licensed, bonded, and insured.
