La Puente is a working-class San Gabriel Valley suburb where homes are lived in hard and held onto — multigenerational households, long-time owners, and a practical attitude toward improvement. People here don’t remodel for show; they remodel because the family needs another bedroom, the kitchen finally gave out, or the plumbing can’t wait any longer.
Practical projects still cross trades, and that’s where homeowners get burned: hiring a handyman for the bath, a separate plumber, and hoping it all lines up. Mars Construction Industries Corp holds four CSLB classifications in-house — A (General Engineering), B (General Building), C-36 (Plumbing), and C-20 (HVAC) — so a La Puente family gets one licensed, bonded, and insured contractor handling the whole job, with a written proposal and a single point of accountability.
Construction & Remodeling Services in La Puente, CA
Our residential work in La Puente focuses on what families actually need: kitchen and bathroom remodels, bedroom and bathroom additions for growing households, and whole-home updates that make an older house work for modern life. We price in clear, combined labor-and-material terms in a written proposal — no vague allowances, no surprise add-ons mid-project.
Behind the walls, we handle the unglamorous work that keeps a house running: repipes for aging galvanized systems, water heater replacement, gas lines, and HVAC install and repair. Our 911 Drain Lines division covers sewer camera inspection, hydro jetting, and trenchless repair — with a 20-year warranty on sewer lining — so a main-line problem gets fixed properly, not patched.
ADUs make strong sense for La Puente’s multigenerational households. Through our sister brand ADU Cities, we’ve delivered more than 100 accessory dwelling units in four years — garage conversions and detached units that give family members their own space, built start to finish by one team.

Why La Puente Property Owners Choose Mars
La Puente homeowners want straight talk and solid work. That’s the whole business 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.
We need more space for family. Is an addition or an ADU better?
It depends on your lot, your budget, and how the family wants to live — and we’ll walk the property with you and lay out both options honestly. Additions tie directly into the house; ADUs give more independence. Either way, one team handles the construction, plumbing, and HVAC.
How does your estimate process work?
We start with a walkthrough of the property, listen to what you want to accomplish, and then put together a written proposal with clear, combined labor-and-material pricing. You get one document from one company covering the construction, plumbing, and HVAC scope — not three separate bids you have to reconcile yourself. There’s no obligation, and we’ll tell you straight if a project doesn’t make sense.
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.
