Buena Park is central Orange County — 1960s and 70s tract neighborhoods plus the entertainment corridor’s commercial energy. The homes are at the age where everything original is ready at once: plumbing, sewer laterals, HVAC, kitchens, baths. Mars Construction Industries sits just down the road in Orange (CSLB #1138550), holding four licenses in-house so Buena Park homeowners get one contractor for the repipe, the remodel, and the new air conditioner — and commercial owners get a TI contractor with plumbing and HVAC under the same roof.
Construction & Remodeling Services in Buena Park, CA
In 60s and 70s tracts, we lead with diagnostics: sewer camera inspections that show the lateral’s real condition, plumbing assessments, and HVAC evaluations. Then one written estimate covers the options — from trenchless sewer lining (20-year warranty) to full repipes to kitchen and bath remodels where our in-house plumbers do every rough-in. Doing systems and finishes together saves a second round of opened walls.
Additions and ADUs are common as families grow into these lots. Through ADU Cities we’ve built 100+ accessory dwelling units in four years, and our builders coordinate every utility tie-in with our own plumbing and HVAC crews — no outside subs to chase.
- Kitchen, bath, and whole-home remodels in 1960s-70s tract homes.
- Repipes, water heaters, and gas lines by licensed in-house C-36 plumbers.
- Sewer and drain services — camera inspection, hydro jetting, trenchless repair, 20-year lining warranty.
- HVAC install, replacement, and repair by our own C-20 crew.
- Room additions and ADUs — 100+ ADUs built in four years via ADU Cities.
- Commercial construction and tenant improvement for the entertainment and retail corridor.
- 24/7 drain & plumbing emergency service via 911 Drain Lines: 714.746.7611.
The entertainment and retail corridor brings commercial work: tenant improvement, restaurant build-outs, and office renovations where holding the C-36 and C-20 licenses in-house keeps multi-trade schedules from slipping.
Why Buena Park 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
Can you do our repipe and our kitchen remodel as one project?
That’s exactly how we prefer to work. Combining the repipe with the remodel means the walls get opened once, the plumbing rough-in serves the new kitchen layout, and you deal with one schedule and one crew sequence. We’ll walk both scopes together and give you one written estimate.
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.
