Bradbury is one of Southern California’s most exclusive addresses — a tiny city of large equestrian estates behind gates, where properties are measured in acres and privacy is part of the purchase price. Construction here is estate work: guest houses, barns and outbuildings, and main residences where every trade has to meet an uncompromising standard.
Estate projects punish fragmented contracting more than anywhere else. A guest house needs structure, plumbing, and HVAC; the main residence repipe has to be sequenced around the family’s life; site work has to respect the property. With A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC in-house, one team plans the estate’s work as a whole — and one principal answers for all of it.
Construction & Remodeling Services in Bradbury, CA
We build and renovate at estate scale: guest houses and ADUs, additions to main residences, and outbuildings including barns and shops — all engineered and built by our in-house teams. Our A General Engineering license covers the structural and site work that large properties demand, from grading-adjacent improvements to drainage that protects the grounds.
Inside the main residence, we handle luxury kitchen and bath renovations, complete repipes, and HVAC designed for large, multi-zone homes where our C-20 team sizes and installs the system as one integrated design. Our 911 Drain Lines division cameras long estate sewer laterals, hydro jets them clear, and rehabilitates failing lines trenchlessly with a 20-year warranty — critical on properties where open trenching would destroy mature landscaping. Discretion, clean jobsites, and direct principal-level communication come standard.

Why Bradbury Property Owners Choose Mars
Most construction projects fall apart in the gaps between trades. The general contractor blames the plumber, the plumber blames the HVAC tech, and the homeowner is left playing referee. Mars Construction Industries Corp was built to eliminate that problem. We have been a licensed general contractor in Southern California backed by 30+ years of hands-on experience, and we hold four CSLB licenses in-house: A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC — CSLB #1138550.
That means one accountable team from the first walkthrough to the final punch list. When your project needs a repipe, a new sewer lateral, and an HVAC changeout in the same week, you make one call and we sequence all of it. No finger-pointing, no scheduling gaps, no “that’s not my trade.”
We are licensed, bonded, and insured, and we carry SB-PW and SB(Micro) small business certifications. Our family of brands — 911 Drain Lines for drain and sewer work, ADU Cities for accessory dwelling units, Get Your Roof Certified, and Universal Inspect for property inspections — means the same company you trust with your remodel can also camera your sewer line, build your ADU, or inspect a property before you buy it.

It starts with a conversation about what you need. We walk the project, put together a clear written scope, and give you straightforward combined pricing — no buried markups, no vague allowances. Call 310.880.9718 or email brett@marsx.construction and we will set up a time to look at your project.
Which trades do you handle in-house?
General construction and remodeling, plumbing, drain and sewer, and HVAC — all under our own CSLB licenses, so one team is accountable for the whole job.

Do you offer emergency service?
For drain and plumbing emergencies, our 911 Drain Lines team is available 24/7 at 714.746.7611 — camera inspections, hydro jetting, and sewer repairs, day or night.
Can you build an ADU on my property?
In many cases, yes. Through our sister brand ADU Cities, we have built more than 100 ADUs in the last four years, so we know how to evaluate a lot, design to the space, and build it right.
Do you take on commercial work?
Yes. We handle commercial and tenant improvement projects — office and retail buildouts, restaurant plumbing, and multi-trade renovations — with the same single-point accountability we bring to residential work.
