San Jacinto is one of Riverside County’s oldest cities, and its housing stock shows it — generations of homes that have sheltered families well but are ready for serious systems work. Where every dollar has to count, the worst outcome is paying three contractors to trip over each other on the same house. A repipe, a sewer lateral, and a new HVAC system are three projects or one project depending on who you hire.
Mars Construction Industries Corp makes it one project. With 30+ years of hands-on experience we’ve been a true multi-trade contractor with four CSLB licenses in-house — A General Engineering, B General Building, C-36 Plumbing, C-20 HVAC (Lic. #1138550). Honest diagnostics, one detailed written estimate, our own licensed crews on the plumbing, building, and HVAC. Licensed, bonded, and insured — and practical about budgets.
Construction & Remodeling Services in San Jacinto, CA
The valley’s summer heat is the first thing our HVAC crews talk about. Aging air conditioners that can’t handle triple-digit stretches are our most common emergency call, and our C-20 crews replace them with properly sized systems — sizing matters enormously here. We also repair honestly when equipment has life left. Underground, older San Jacinto homes often need the unglamorous work: cast-iron drains, corroded supply lines, laterals never inspected. Our camera inspections give you video evidence, and trenchless lining with a 20-year warranty fixes failing lines without the excavation bill.
When the bones are good, we do the visible work: budget-honest kitchen and bath remodels, room additions, and ADUs — 100+ built in four years through ADU Cities — a strong fit for the valley’s multigenerational households. Repipes, water heaters, and gas lines come from our own C-36 crews, coordinated under one schedule.

Why San Jacinto Property Owners Choose Mars
The classic remodeling horror story goes like this: three contractors, three schedules, and nobody responsible when something goes wrong. We’re the opposite of that. Mars Construction Industries Corp is licensed, bonded, and insured (CSLB #1138550), backed by 30+ years of hands-on experience, and we hold four trade licenses in-house — A General Engineering, B General Building, C-36 Plumbing, C-20 HVAC — so most of your project never leaves our own crews.
That changes the experience: the company that bids your kitchen remodel also moves the gas line, sizes the HVAC for the new floor plan, and handles the structural work. No finger-pointing between subs, no stacked mystery markups, no waiting weeks for a trade contractor to fit you in.
We’re based in Orange, California, and carry SB-PW and SB(Micro) certifications. Through 911 Drain Lines, ADU Cities, Get Your Roof Certified, and Universal Inspect, we serve a property end to end — from the sewer lateral (our trenchless lining has a 20-year warranty) to the roof. San Jacinto hires us because one accountable team is simply easier, and the work turns out better.

Frequently Asked Questions
What areas do you serve?
We’re based in Orange, California, working within roughly a 50-mile radius across Orange County, LA County, and the Inland Empire. San Jacinto is squarely in our service area — our crews are in Riverside County regularly.
Do you handle every trade in-house?
The trades that matter most — building, plumbing, HVAC — are our own licensed crews under CSLB #1138550. For specialty scopes outside our four licenses, we bring in vetted specialists and manage them. Either way, you deal with one accountable team and one point of contact.
Can you build an ADU on my property?
Yes — through ADU Cities we’ve built 100+ ADUs in four years. Design, permitting support, and construction in one design-build package: garage conversions, detached units, and attached additions.
Our AC can’t keep up in summer. Repair or full replacement?
We’ll tell you straight. Our C-20 technicians diagnose the actual condition — refrigerant, compressor, airflow, ducts — and give you both options with honest math. In valley heat, sizing the replacement correctly matters as much as the equipment itself, and we’ll show you the reasoning, not just a tonnage number.
