General Contractor in Westlake Village, CA | Mars Construction Industries

Westlake Village is an upscale planned community built around its namesake lake — a city of custom homes, lakefront properties, and quiet neighborhoods where homeowners invest seriously in how they live. The housing here trends toward substantial single-family homes: properties with outdoor living spaces, larger floor plans, and owners who expect high-end finishes and disciplined project management. Renovations here are often whole-home in scale — kitchens opened to great rooms, primary suites expanded, outdoor kitchens and living areas plumbed and built as part of the plan. Projects at this level cross trade lines as a matter of course, and they deserve one accountable team holding all the licenses.

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 team, one contract, and one point of responsibility for your construction, plumbing, drain and sewer work, and HVAC.

Construction & Remodeling Services in Westlake Village, CA

Our Westlake Village work centers on whole-home remodels and high-end renovations: kitchens expanded and opened to living areas, primary suites reconfigured, bathrooms finished to a luxury standard. Because we hold C-36 plumbing and C-20 HVAC licenses in-house, these projects include fixture relocations, gas line extensions, and climate system upgrades as part of the same coordinated plan — the infrastructure and the finishes designed together, not bolted on by separate contractors.

Outdoor living is a defining feature of Westlake Village homes, and we build it as part of the whole: outdoor kitchens with gas and water lines, covered living areas, and the plumbing and drainage that make them work year-round. Room additions — great rooms, expanded kitchens, guest suites — are engineered to integrate with the existing home inside and out.

We also handle the infrastructure side: repipes, water heater replacements, and gas line work; drain and sewer services including camera inspection, hydro jetting, and trenchless sewer repair, with a 20-year warranty on our sewer lining. Lake-adjacent and larger lots are exactly where trenchless methods earn their keep — renewing a lateral without disturbing established grounds. And we install, replace, and repair HVAC systems, including multi-zone setups for larger homes. ADUs and guest houses fit many properties here; through our sister brand ADU Cities, we’ve built more than 100 ADUs in four years.

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 for large renovations?

We walk the property with you, assess the full scope — including infrastructure and outdoor living — and provide a written estimate. For whole-home work, we lay out the sequence of trades so you can see how the project flows from rough work to finishes.

Can you include an outdoor kitchen in my remodel?

Yes. Outdoor kitchens with gas and water lines, covered living areas, and associated drainage are projects we design and build as part of the whole — our in-house plumbing license covers the utility work.

Which trades do you handle in-house?

General construction and remodeling, plumbing, drain and sewer, and HVAC, all under our own licenses. Electrical work is performed by qualified licensed electricians we bring in, since we do not hold the C-10 electrical classification.

Do you handle plumbing or sewer emergencies?

Yes. Our sister brand 911 Drain Lines provides 24/7 drain and plumbing emergency service at 714.746.7611.
