Azusa sits against the San Gabriel foothills — an older foothill city where homes have history and the housing stock shows it. Original plumbing, aging sewer laterals, and HVAC systems that have worked hard for decades are the norm, not the exception. Mars Construction Industries (CSLB #1138550) is built for foothill-city homes like these: one licensed company holding the building, plumbing, and HVAC licenses, so Azusa owners get honest diagnostics and one team to fix what’s found.
Construction & Remodeling Services in Azusa, CA
We start old-home projects with evidence, not assumptions. Sewer camera inspections show the lateral’s real condition; plumbing assessments check pressure, visible piping, and fixtures; HVAC evaluations tell you whether repair or replacement is the smart money. Then one written estimate lays out the options — repipe, trenchless sewer lining with our 20-year warranty, water heater, system replacement.
Kitchen and bath remodels in Azusa’s older homes almost always touch systems: moving a drain, upgrading a water heater, reworking HVAC for an opened floor plan. Our in-house plumbers and HVAC techs do that work as part of the remodel — same company, same schedule, no subcontractor roulette.

Why Azusa 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
Our home is older and we’re worried a remodel will uncover expensive surprises. How do you handle that?
Honestly and up front. We inspect before we quote — camera the sewer, check the plumbing, look at the structure we can see — so the estimate reflects reality, not hope. If we open a wall and find something unexpected, you hear about it immediately with options and pricing before we proceed. No surprises buried in a final invoice.
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.
