General Contractor in Los Alamitos, CA | Mars Construction Industries

Los Alamitos is small-town Orange County — a compact suburb of 1960s tract homes, good schools, and neighbors who know each other. The housing here is remarkably consistent: single-story ranches built in the 60s, now fifty-plus years old and due for their second major update cycle. Original bathrooms, aging supply lines, tired kitchens, and HVAC systems well past their prime — Los Alamitos homes need a contractor who can do the whole job. Mars Construction Industries Corp is a multi-trade GC with construction, plumbing, drain/sewer, and HVAC licenses in-house, headquartered minutes away in Orange. One team, one schedule, one company accountable.

Construction & Remodeling Services in Los Alamitos, CA

The classic Los Alamitos project is the ranch-house refresh: kitchen opened to the living areas, bathrooms rebuilt, flooring and paint throughout, and the systems brought current — all in one coordinated project. Doing it together instead of piecemeal saves real money, because the walls are opened once for plumbing and mechanical rough-in. Our C-36 plumbers handle repipes, water heaters, and fixture work in-house; our C-20 team handles HVAC replacement; our B-licensed crews handle everything structural and finish.

Kitchen remodels in these ranches transform how the house lives. A wall between kitchen and dining room comes down, an island goes in, and a closed-off 1960s floor plan becomes an open family space. Bathrooms trade original tub-shower combos for walk-in showers and modern vanities, built on proper waterproofing — essential in homes where slow leaks have had decades to work. We also build additions — a second bathroom, a primary suite, a home office — and ADUs through our sister brand ADU Cities, with more than 100 completed in four years.

Drain and sewer work comes through 911 Drain Lines: camera inspections, hydro jetting, and trenchless repair with a 20-year lining warranty — important in neighborhoods where original clay or cast-iron laterals are reaching end of life. Emergency service runs 24/7 at 714.746.7611.

Frequently Asked Questions

Are you a licensed contractor?

Yes. Mars Construction Industries Corp is CSLB #1138550 with 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 do my whole house at once or room by room?

For 1960s ranches where kitchen, baths, and systems all need attention, combining the work is usually more efficient — one demolition phase, one rough-in phase, one disruption. We’ll walk your home and recommend the smartest sequence 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, is performed by licensed specialty subcontractors we manage.

Do you handle sewer line problems in older neighborhoods?

Yes. Camera inspections diagnose the lateral, hydro jetting clears buildup, and trenchless repair replaces failed lines without major digging — with a 20-year warranty on lining. 24/7 emergency service at 714.746.7611.

Can you build an ADU on my lot?

In many cases, yes. Through ADU Cities we’ve built more than 100 ADUs in four years, and we evaluate each Los Alamitos property individually.

How do your estimates work?

We walk the project with you, scope it fully, and deliver a written estimate with combined labor-and-material pricing — the complete picture before work begins.
