Temple City is a San Gabriel Valley suburb built largely in the mid-century — tract homes from the 1950s through the 1970s on quiet residential streets, home to families who value the neighborhood feel and the central location. Those mid-century homes are now at the age where systems need attention: original or once-replaced plumbing nearing the end of its life, sewer laterals from the tract era, water heaters and furnaces due for replacement, and kitchens and baths that haven’t been touched in decades. It’s the classic Southern California renovation market — and it’s exactly where a multi-trade contractor earns its keep, because the remodel and the repipe almost always belong in the same project.
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.
Construction & Remodeling Services in Temple City, CA
Kitchen and bathroom remodels lead our Temple City work. Mid-century kitchens get full renovations — new layouts, modern plumbing, gas lines for new ranges — and bathrooms get updated fixtures, tile, and supply lines. With our C-36 plumbing license in-house, fixture relocations and pipe renewal are part of the same job, not a separate contractor’s visit. Homeowners who pair a remodel with a full repipe open their walls once and get both new infrastructure and new finishes.
Additions and ADUs serve Temple City’s growing households. We build room additions — bedrooms, expanded living areas — and ADUs through our sister brand ADU Cities, which has built more than 100 ADUs in four years. An ADU on a mid-century lot gives extended family independent space without changing the neighborhood character of the street.
Our drain and sewer services address the tract-era laterals: camera inspection, hydro jetting, and trenchless sewer repair, with a 20-year warranty on sewer lining. Trenchless methods rehabilitate a failing line without tearing up the driveway or front yard. We also install, replace, and repair HVAC systems — many mid-century homes still run aging or undersized equipment — and we handle commercial tenant improvement for the small businesses along the city’s corridors.

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 any license on the CSLB website before hiring. Ours is CSLB #1138550 — A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC.
How does your estimate process work?
We visit the home, walk through the project with you, and provide a written estimate. In mid-century homes, we check plumbing, sewer, and HVAC conditions so the estimate covers the real scope — not just the finishes.
Should I repipe if I’m already remodeling?
In many mid-century homes, yes — it’s the most cost-effective time. Walls are already open, so renewing supply lines adds relatively little disruption compared to doing it as a separate project later. We’ll assess your pipes and give you a straight recommendation.
Can you build an ADU on my lot?
Often, yes. We’ve built more than 100 ADUs in four years through our sister brand ADU Cities. We’ll evaluate your lot and discuss the options that fit.
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.
