Chino Hills is upscale master-planned living — newer homes, hillside views, and owners who expect their contractor to match the neighborhood’s standards. The work here is high-end remodeling, additions, outdoor-living-adjacent interiors, and keeping premium systems in top shape. Mars Construction Industries (CSLB #1138550) holds four licenses in-house, so Chino Hills owners get one polished, accountable team for the luxury kitchen, the repipe, the new HVAC, and everything between. Inland Empire: 909.325.0020.
Construction & Remodeling Services in Chino Hills, CA
High-end remodels demand coordination, and coordination is what the four-license model is for. Our builders run luxury kitchen and bath renovations, whole-home updates, and additions; our in-house C-36 plumbers handle every rough-in, gas line, and fixture; our C-20 crew sizes and installs HVAC for larger hillside homes. One contract, one schedule, one standard of finish.
Even newer homes need systems attention: builder-grade HVAC aging out, water heaters reaching end of life, the occasional drain issue. We diagnose honestly, quote in writing, and fix it right — and our 911 Drain Lines brand answers drain and plumbing emergencies 24/7 at 714.746.7611, with trenchless repair backed by a 20-year lining warranty.

Why Chino Hills Property Owners Choose Mars
Most remodeling projects fail in the gaps between trades. The plumber roughs in before the framer is done, the HVAC sub never shows, and the homeowner ends up project-managing three companies that blame each other. We built Mars Construction Industries to eliminate that problem. We hold four CSLB classifications in-house — A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC — so the crew doing your addition is the same company doing your repipe and your HVAC changeout.
We’ve been at it with 30+ years of hands-on experience, working from our Orange County home base across Southern California. We’re licensed, bonded, and insured (CSLB #1138550), and our SB-PW and SB(Micro) certifications reflect a company built to do right by the communities we serve. When you hire Mars, you get one accountable team, one phone number, and one company standing behind the finished work.
Our sister brands extend that accountability: 911 Drain Lines for drain and sewer emergencies, ADU Cities for accessory dwelling units, Get Your Roof Certified for roof certifications, and Universal Inspect for inspection services. Whatever your property needs, there’s a Mars team for it.

Frequently Asked Questions
We’re particular about finish quality. How do you protect that during construction?
With process: detailed scopes in writing before work starts, dust and floor protection as standard practice, daily cleanup, and a final walkthrough where we go through the work together. Our crews do high-end work regularly — the estimate stage is where we align on materials, finishes, and exactly what ‘done’ looks like.
Are you a licensed contractor?
Yes. Mars Construction Industries Corp holds CSLB license #1138550 with four classifications: 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 California contractor’s license status at cslb.ca.gov.
How does your estimate process work?
It starts with a conversation and a walkthrough of the project. We look at the full scope, identify what each trade will need to touch, and give you a written estimate with clear, combined pricing. Because our plumbers, HVAC techs, and builders all work for the same company, we price the whole job once instead of stacking separate subcontractor bids with separate markups.
Which trades do you keep in-house?
General construction and remodeling, plumbing, drain and sewer, and HVAC are all in-house under our four license classifications. When a project also needs electrical work, we coordinate with licensed electrical subcontractors so the work stays on one schedule under one accountable team.
Do you offer emergency service?
Yes. Our 911 Drain Lines brand runs 24/7 drain and plumbing emergency service at 714.746.7611. For sewer line emergencies, we can camera-inspect the line, clear it, and talk through repair options including trenchless repair and sewer lining backed by a 20-year warranty.
Do you build ADUs?
Yes. Through our sister brand ADU Cities, we’ve built more than 100 accessory dwelling units in the last four years. From detached backyard units to garage conversions, we handle the full build with the same in-house plumbing, HVAC, and general construction crews.
