San Bernardino is the Inland Empire’s historic anchor — a big, real city with a downtown, older neighborhoods with genuine character, and a housing stock that spans a century. That range is exactly why a multi-trade general contractor matters here. A 1920s bungalow near downtown, a 1960s ranch in the north end, and a newer home on the city’s edges have almost nothing in common except one thing: sooner or later, they all need a contractor who can handle structure, plumbing, and HVAC in one project without disappearing between trades. Mars Construction Industries Corp does that work, backed by 30+ years of hands-on experience, with four licenses in-house and one team accountable for the result.
Construction & Remodeling Services in San Bernardino, CA
In the city’s older neighborhoods, we do a lot of infrastructure-first work. Cast-iron drains, galvanized supply lines, aging water heaters, and HVAC systems held together with hope — we diagnose with camera inspections and honest evaluations, then fix it right: hydro jetting, trenchless sewer repair and lining with a 20-year warranty, whole-house repipes, water heater replacement, and full HVAC changeouts. Cosmetic work on top of failing systems is money wasted, and we’ll tell you so.
Once the bones are sound, San Bernardino homeowners invest in the same upgrades as anywhere else: kitchens with modern cabinetry and counters, bathrooms rebuilt with proper waterproofing and fixtures, and room additions that give growing families breathing room. Our A (General Engineering) license is a real asset on structural work in older homes — foundations, framing corrections, and additions tied into structures that weren’t built to today’s standards. We also build ADUs through our sister brand ADU Cities, with more than 100 completed in four years.
On the commercial side, San Bernardino’s downtown and commercial corridors generate steady tenant improvement, restaurant, and office work. We handle commercial construction, commercial plumbing, and commercial HVAC — and because our trades are in-house, a TI buildout doesn’t stall waiting on a plumber who answers to someone else.
