Rolling Hills Estates pairs an equestrian heritage with an upscale suburban feel — larger lots, mid-century ranch homes, and custom properties in a community that values privacy and open space. Many homes here were built in the ranch-house era and have good bones but dated systems: original plumbing, aging water heaters, HVAC equipment long past its prime, and kitchens and baths designed for a different generation. A renovation here often means updating the infrastructure and the living spaces together, and that only works smoothly when the same team controls both.
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, your plumbing, your drain and sewer work, and your HVAC — so a Rolling Hills Estates remodel doesn’t stall in the gaps between separate trades.
Construction & Remodeling Services in Rolling Hills Estates, CA
Kitchen and bathroom remodels are our most common work in Rolling Hills Estates, and they’re exactly where multi-trade capability pays off. A kitchen remodel here often involves moving the sink or range, extending a gas line, and upgrading ventilation and cooling — with our C-36 plumbing and C-20 HVAC licenses in-house, all of that stays inside one contract and one schedule. The same goes for bathroom remodels and additions, where drain layouts, water lines, and exhaust all have to be right before tile goes up.
Ranch-era homes also reward attention to what’s behind the walls. We perform full repipes, water heater replacements, and gas line work, and our drain and sewer services include camera inspection, hydro jetting, and trenchless sewer repair. Our sewer lining carries a 20-year warranty — a meaningful protection on larger lots where a failed lateral can run a long distance under landscaping. Trenchless repair lets us rehabilitate the line without tearing up the yard.
Because lots here are generous, additions and ADUs make sense for many families. We build room additions — primary suites, expanded kitchens, great rooms — and ADUs for multigenerational living or guest housing. Through our sister brand ADU Cities, we’ve built more than 100 ADUs in four years. We also install and replace HVAC systems, including multi-zone setups for larger homes.

Frequently Asked Questions
Do I need a licensed contractor for my project?
In California, any construction project totaling $1,000 or more in labor and materials must be performed by a licensed contractor. Verify licensing on the CSLB website before hiring anyone. Our license is CSLB #1138550 — A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC.
How does your estimate process work?
We come to the property, walk through the project with you, and provide a written estimate. For remodels in ranch-era homes, we look closely at plumbing, gas, and HVAC conditions so the estimate reflects the real scope — not just the finishes.
Can you handle the plumbing and HVAC inside a remodel?
Yes. Our C-36 plumbing and C-20 HVAC licenses are held in-house, so relocations, repipes, gas lines, and climate system upgrades are part of the same contract. Electrical work is performed by qualified licensed electricians we bring in, since we do not hold the C-10 electrical classification.
Do you build ADUs?
Yes — more than 100 in four years through our sister brand ADU Cities. ADUs work well on Rolling Hills Estates’ larger lots for multigenerational family or guest housing.
Do you offer emergency plumbing service?
Yes. Our sister brand 911 Drain Lines provides 24/7 drain and plumbing emergency service at 714.746.7611.
