Montebello carries a long history — from its oil-field past to its present as a diverse southeast suburb of mid-century homes, commercial corridors, and quiet residential streets. Much of the housing stock dates to the postwar boom, which means a lot of homes are now at the age where original systems need serious attention.
Postwar neighborhoods are the natural habitat of the multi-trade contractor. A Montebello kitchen remodel opens walls with 60-year-old galvanized pipe; a bathroom addition needs the sewer lateral and the HVAC touched 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 renovation and the mechanical renewal happen as one coordinated project, not three separate headaches.
Construction & Remodeling Services in Montebello, CA
Our residential work in Montebello centers on the mid-century home renewal: kitchen and bath remodels, whole-home updates, and room additions — each paired with the behind-the-walls work these houses need. Our own C-36 crews perform full repipes, water heater and gas line replacement, and fixture upgrades, usually coordinated with the remodel so walls open once.
Sewer laterals are a common concern in neighborhoods of this era. Our 911 Drain Lines division camera-inspects the line and shows you the footage, clears roots and buildup with hydro jetting, and repairs trenchlessly where the pipe qualifies — our sewer lining carries a 20-year warranty. It’s straightforward, documented work: you see what we see before any decision.
We also serve Montebello’s commercial corridors with tenant improvements — retail, office, and restaurant buildouts with in-house plumbing and HVAC, phased for operating businesses. And through our sister brand ADU Cities (100+ units delivered in four years), we build ADUs and garage conversions on Montebello’s lots.

Why Montebello Property Owners Choose Mars
Montebello’s homes are at the age where systems and finishes need each other. Here’s the one-team approach:
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.
Should we repipe when we remodel, or can the old plumbing stay?
If the walls are opening for a remodel and the home still has galvanized or corroded lines, doing the repipe at the same time is almost always the smarter move — one demolition, one patch, one project. We’ll show you the condition of your lines during the walkthrough so the decision is based on evidence.
How do I know if my sewer line needs work?
Recurring backups, slow drains across the house, gurgling fixtures, or soggy spots in the yard all warrant a camera inspection. We show you the footage and recommend repair only if what we see justifies it — trenchless lining where applicable 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.
