Signal Hill is a city unlike any other in the region — a hilltop enclave completely surrounded by Long Beach, with oil-town roots, panoramic views, and a housing mix that runs from mid-century homes to newer hillside builds. The hilltop setting shapes the work: homes positioned for views, lots with real grade, and a blend of older houses needing infrastructure renewal and newer homes focused on improvement. Commercial corridors at the base of the hill add tenant improvement work to the mix. It’s a small city where projects still cross trade lines constantly — a remodel that needs a repipe, a hillside home that needs drainage and sewer attention, a business space that needs a full build-out.
Mars Construction Industries Corp is a multi-trade general contractor based in Orange, CA, operating with 30+ years of hands-on experience. We hold four CSLB licenses in-house — A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC (CSLB #1138550). One accountable team handles your construction, plumbing, drain and sewer work, and HVAC under a single contract.
Construction & Remodeling Services in Signal Hill, CA
Our Signal Hill residential work covers the city’s full housing range. In older homes, we perform repipes, water heater replacements, and gas line work — in-house under our C-36 license — paired with kitchen and bathroom remodels so infrastructure and finishes move as one project. On the hill’s newer homes, we focus on kitchen and bath upgrades, room additions, and whole-home renovations that take advantage of the views and the lots.
Hilltop lots make drain and sewer work especially worth doing right. We provide camera inspection, hydro jetting, and trenchless sewer repair, with a 20-year warranty on our sewer lining — rehabilitating failing laterals without the excavation that hillside properties make so disruptive. Trenchless methods protect landscaping and hardscaping while delivering a renewed line.
We install, replace, and repair HVAC systems for the hill’s microclimate — where exposure and elevation change the comfort equation. And for the commercial base of the hill, we handle tenant improvement: office, retail, and restaurant build-outs that combine construction with plumbing and HVAC under one contract. ADUs are also a fit here; through our sister brand ADU Cities, we’ve built more than 100 in four years.

Frequently Asked Questions
Do I need a licensed contractor for my project?
In California, any construction project totaling $1,000 or more in labor and materials must be performed by a licensed contractor. Verify any license on the CSLB website before hiring. Ours is CSLB #1138550 — A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC.
How does your estimate process work?
We visit the property, walk through the project with you, and provide a written estimate. For multi-trade projects, we scope the whole job at once so you’re dealing with one number and one team.
Can you handle a remodel and a repipe together?
Yes. Our B license covers the construction and our C-36 covers the plumbing — one coordinated project, one contract, walls opened once.
