La Mirada is one of Southern California’s classic planned suburbs — most of it built out in the 1950s and 60s, with tidy tract homes on good-sized lots. Sixty-plus years later, those homes are hitting the age where the systems behind the walls matter as much as the finishes: original galvanized plumbing, cast-iron sewer lines, and HVAC equipment on its second or third replacement cycle.
That’s the sweet spot for a multi-trade general contractor. A La Mirada kitchen remodel usually uncovers plumbing that should have been replaced a decade ago, and a bathroom addition needs HVAC extended at the same time. Mars Construction Industries Corp holds four CSLB classifications in-house — A (General Engineering), B (General Building), C-36 (Plumbing), and C-20 (HVAC) — so the remodel and the mechanical renewal happen as one project, managed by one team.
Construction & Remodeling Services in La Mirada, CA
Our core work in La Mirada is the mid-century tract renovation: kitchen and bath remodels, whole-home updates, and room additions that give a 1950s floor plan modern flow. Because we self-perform plumbing and HVAC, we routinely pair the cosmetic work with what’s needed behind the walls — full repipes replacing galvanized lines, new water heaters, and right-sized HVAC systems.
Sewer lines are a recurring issue in neighborhoods of this era. Our 911 Drain Lines division camera-inspects laterals, shows you the footage, and repairs with hydro jetting or trenchless methods where the line qualifies — our sewer lining carries a 20-year warranty. It’s the kind of work that’s invisible when done right and miserable when ignored.
La Mirada’s lots also suit ADUs well. Through our sister brand ADU Cities, we’ve delivered more than 100 accessory dwelling units in four years — garage conversions and detached backyard units that add housing for family or rental income, built start to finish by one team.

Why La Mirada Property Owners Choose Mars
La Mirada homes are at the age where the walls need to come open anyway. Here’s why owners do it all with one team:
Mars Construction Industries Corp is a general contractor backed by 30+ years of hands-on experience, based in Orange, California. We are licensed, bonded, and insured, holding four CSLB classifications in-house under license #1138550: A (General Engineering), B (General Building), C-36 (Plumbing), and C-20 (HVAC). We are also SB-PW and SB(Micro) certified.
That means one accountable team. Most projects cross trades, and that is where jobs stall — the plumber blames the framer, and you are left managing people who do not work for you. With Mars, the general contractor, the plumbing crew, and the HVAC crew are the same company: one estimate, one schedule, one phone number, and no gaps between trades.

Frequently Asked Questions
Is Mars Construction Industries Corp licensed for this work?
Yes. We operate under CSLB license #1138550 with four classifications in-house: A (General Engineering), B (General Building), C-36 (Plumbing), and C-20 (HVAC). We are licensed, bonded, and insured, and we hold SB-PW and SB(Micro) small-business certifications. You can verify any contractor’s license status through the Contractors State License Board before you sign anything — and you should.
My home still has its original 1950s plumbing. Do you repipe?
Yes — whole-house repipes are one of our core services. We replace aging galvanized and cast-iron systems with modern piping, usually coordinated with a kitchen or bath remodel so walls are opened once. Our C-36 plumbing crews do the work in-house.
How do I know if my sewer line is failing?
Slow drains throughout the house, recurring backups, gurgling fixtures, or lush patches in the yard are all worth a camera inspection. We run a camera through the line and show you exactly what we see — then recommend repair only if the footage justifies it. Trenchless lining, where it applies, carries a 20-year warranty.
Do you subcontract everything out?
No. We self-perform across our four licensed classifications — general construction, plumbing, drain and sewer, and HVAC — which covers the bulk of most residential and commercial projects. For work outside our classifications, such as electrical, we coordinate properly licensed subcontractors and stay accountable for their work as your general contractor. You still deal with one team.
