La Habra sits at Orange County’s northern doorstep — an older, established suburb of 1950s through 70s homes where families stay for decades. These are the neighborhoods where the original owners raised their kids and the second owners are now raising theirs, which means the houses are entering their second major lifecycle: not just cosmetic updates, but systems renewal.
Second-lifecycle homes are the strongest case for a multi-license GC. The repipe, the sewer lateral, the HVAC replacement, and the kitchen remodel are all due in the same five-year window — doing them as disconnected jobs means paying for demolition, drywall, and scheduling four separate times. With A, B, C-36, and C-20 in-house, we plan the whole renewal as one coordinated project and open each wall exactly once.
Construction & Remodeling Services in La Habra, CA
Plumbing renewal leads the work in La Habra’s older tracts: whole-home repipes that replace corroded galvanized lines, water heater replacements, and gas line upgrades by our in-house C-36 plumbers. Our 911 Drain Lines division cameras sewer laterals to find root intrusion and separations common in mature neighborhoods, then clears them with hydro jetting or rehabilitates them trenchlessly with a 20-year lining warranty.
With systems sound, we remodel the kitchens and bathrooms that date these homes — layouts opened for modern family life, proper ventilation and waterproofing, finishes built to last. Our C-20 team replaces aging furnaces and air conditioners with correctly sized equipment. Growing families get room additions and ADUs designed to match the existing home, all planned, permitted-scope coordinated, and built by one accountable crew.

Why La Habra 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.

Can you build an ADU on my property?
