Lakewood is the iconic postwar planned suburb — thousands of homes built in the early 1950s, many still carrying their original floor plans and, more importantly, their original plumbing. Seventy-plus years on, those houses are at a turning point: the galvanized water lines and cast-iron sewer laterals they were built with are reaching the end of their service life all at once.
This is precisely the moment a multi-trade general contractor matters. A Lakewood kitchen remodel that opens walls with original galvanized pipe behind them shouldn’t get new cabinets hung over dying plumbing — and the crew doing the remodel should be the crew replacing the pipes. 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 project, under one accountability.
Construction & Remodeling Services in Lakewood, CA
Whole-house repipes are among our most common jobs in Lakewood. Our C-36 plumbing crews replace aging galvanized and cast-iron systems with modern piping — and because we’re also the remodeling contractor, we routinely coordinate repipes with kitchen and bath renovations so walls open once, not twice. New water heaters, gas lines, and fixture upgrades come with the same crew.
Sewer laterals are the other half of the story in a 1950s neighborhood. 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. No guesswork, no scare tactics; you see what we see.
For the living space itself, we do kitchen and bath remodels that respect the Lakewood floor plan while opening it up for modern life, plus room additions and ADUs. Through our sister brand ADU Cities, we’ve delivered more than 100 accessory dwelling units in four years — garage conversions and detached units that fit Lakewood’s lots. And our C-20 crews handle HVAC replacement for systems that have served several decades.

Why Lakewood Property Owners Choose Mars
In a neighborhood where every house is the same age, the smart money fixes systems and finishes together. Here’s our model:
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 Lakewood home still has original plumbing. Do you repipe?
Yes — whole-house repipes are core work for us, especially in postwar neighborhoods like Lakewood. We replace galvanized and cast-iron systems with modern piping, and we strongly recommend coordinating a repipe with any kitchen or bath remodel so walls are opened once. Our C-36 crews do the work in-house.
How do I know if my sewer lateral is failing?
Recurring backups, slow drains throughout the house, gurgling fixtures, or soggy areas in the yard all warrant a camera inspection. We run a camera through the line and show you the footage before recommending anything. Where trenchless lining applies, it 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.
