Costa Mesa sits between the beach and the freeway — older beach-adjacent homes with coastal wear, mid-century tracts, and sharp new builds all sharing the same zip codes. Salt air ages exteriors and HVAC equipment faster, and the older housing stock hides original plumbing and tired sewer laterals. Mars Construction Industries (CSLB #1138550), based minutes away in Orange, holds four licenses in-house so Costa Mesa owners get one team for the remodel, the repipe, the sewer line, and the AC.
Construction & Remodeling Services in Costa Mesa, CA
Coastal proximity shows up in the work: HVAC systems corrode faster near the ocean, and exterior and structural elements take more abuse. Our C-20 crew installs and replaces systems selected for coastal conditions, and our builders handle the remodels and additions where salt-air wear meets 1960s construction — kitchens, baths, whole-home updates, and second-story additions.
Underground, Costa Mesa’s older neighborhoods tell the usual story: cast-iron drains, aging supply lines, laterals with decades of root intrusion. We camera-inspect before quoting, repipe where warranted, and offer trenchless sewer repair and lining backed by our 20-year warranty — often saving mature landscaping and hardscaping.

Why Costa Mesa 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
Does being near the coast really affect my HVAC system?
Yes — salt air accelerates corrosion on outdoor equipment, shortening lifespans compared to inland units. We factor that into replacement recommendations: proper equipment selection, protective measures, and realistic maintenance expectations. Our C-20 crew will assess your current system honestly and quote replacement or repair in writing.
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.
