Laguna Hills grew up as one of south Orange County’s original planned communities, and its 1970s- and 1980s-era neighborhoods are hitting a familiar milestone: everything original is wearing out at once. The tract kitchens with oak cabinets, the bathrooms with cultured-marble vanities, the original HVAC systems, the water heaters, the supply lines — after forty-plus years, a house needs a real refresh, not a patch. That’s the moment to hire a general contractor who can do all of it. Mars Construction Industries Corp is a multi-trade GC with four licenses in-house, so your Laguna Hills remodel, repipe, or HVAC replacement is handled by one accountable team instead of a parade of subcontractors.
Construction & Remodeling Services in Laguna Hills, CA
The most common project we see in Laguna Hills is the whole-home update: kitchen, primary bath, flooring, paint, and fixtures, modernized in one coordinated push. Doing it as a single project instead of five separate ones saves real money and disruption, because the walls are already open for the plumbing and electrical rough-in. Our B license covers the construction, our C-36 covers every water and gas line we touch, and our C-20 covers the HVAC — which, in a 40-year-old home, often needs upsizing or re-ducting to heat and cool evenly.
Kitchens and bathrooms are where Laguna Hills homeowners see the biggest return on both daily life and resale. We open closed kitchens to the family room, install proper island seating and storage, and rebuild bathrooms with walk-in showers, quality tile, and fixtures that will last another forty years. We also build room additions for growing families and ADUs for multigenerational households — detached units and garage conversions, with more than 100 ADUs completed in four years through our sister brand ADU Cities.
Behind the finishes, we keep the systems current: whole-house repipes for aging copper and galvanized lines, water heater replacement (including tankless where it makes sense), gas lines for outdoor living, and drain and sewer service through 911 Drain Lines — camera inspections, hydro jetting, and trenchless repair backed by a 20-year lining warranty. If your air conditioning struggles through September, our HVAC team installs and services full systems sized for your home’s actual load.

Why Laguna Hills Property Owners Choose Mars
A planned-community home is a system: the plumbing, the ductwork, the structure, and the finishes were all designed together, and a remodel has to respect that. Mars holds A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC licenses in-house under CSLB #1138550 — so when your project crosses trades, which it will, the same company owns every part of it. No coordination gaps, no blame-shifting between the plumber and the framer.
We’ve been at this with 30+ years of hands-on experience. Mars Construction Industries Corp is licensed, bonded, and insured, and holds SB-PW and SB(Micro) small-business certifications. One call, one crew, one company accountable for the result — that’s the whole pitch, and three decades of work backs it up.

Frequently Asked Questions
Are you a licensed contractor?
Yes. Mars Construction Industries Corp is CSLB #1138550, holding A (General Engineering), B (General Building), C-36 (Plumbing), and C-20 (HVAC). Licensed, bonded, and insured, with SB-PW and SB(Micro) certifications.
Should I remodel everything at once or phase it?
It depends on budget and disruption tolerance, but combining kitchen, baths, and systems work into one project is usually more efficient — walls are opened once, trades sequence once, and you live through construction once. We’ll walk the house and give you an honest recommendation either way.
Which trades do you keep in-house?
General construction, plumbing, drain and sewer, and HVAC — all under our own licenses. Work outside those classifications, such as electrical contracting, goes to licensed specialty subcontractors we manage directly.
Do you replace old HVAC systems?
Yes. We install, replace, and repair full HVAC systems, including re-ducting and load calculations so the new system actually matches your home.
Do you handle sewer and drain issues?
Yes, through 911 Drain Lines: camera inspections, hydro jetting, and trenchless repair with a 20-year warranty on lining. 24/7 emergency service at 714.746.7611.
Can you build an ADU on my property?
In most cases, yes. Through ADU Cities we’ve built more than 100 ADUs in four years — detached, garage conversion, and attached — from design through final inspection.
