Alhambra is one of the San Gabriel Valley’s classic older suburbs — mid-century homes, many with original plumbing and electrical-era infrastructure, sitting on lots where families stay for generations. These homes reward a contractor who understands old houses: cast-iron drains, aging water lines, and remodels that have to work around what’s already in the walls. Mars Construction Industries (CSLB #1138550) holds the general building, plumbing, and HVAC licenses in-house, so Alhambra homeowners get one team that can open a wall, fix what’s behind it, and finish the room.
Construction & Remodeling Services in Alhambra, CA
Mid-century homes in Alhambra tend to need systems work before cosmetic work. We do full repipes for homes still running original supply lines, sewer camera inspections that show exactly what decades have done to the lateral, and trenchless sewer repair or lining — backed by our 20-year warranty — when digging up the yard isn’t the answer. Our 911 Drain Lines brand also runs 24/7 emergency service at 714.746.7611.
Kitchen and bath remodels are where the multi-license model pays off most in older homes. Moving a sink means moving drain and supply; adding a shower means rethinking the water heater; opening a floor plan means the HVAC layout changes. One company, one estimate, one schedule — no waiting on a plumber your GC doesn’t control.

Why Alhambra 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 still has its original plumbing. How do we know if it needs a full repipe?
Start with an inspection. We’ll check water pressure, look at accessible piping, test fixtures, and camera the sewer lateral so you’re deciding based on evidence, not guesswork. If a repipe makes sense, our in-house plumbers do the whole job.
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.
