South Pasadena calls itself the City of Trees, and the nickname fits — a historic small city of vintage homes, Craftsman and Victorian-era houses, and streets where the architecture is part of the community’s identity. Renovating here is a particular discipline: homeowners want modern kitchens, baths, and systems, but they want the home’s character intact. Beneath those vintage finishes, the infrastructure is often original — old supply lines, aging sewer laterals, furnaces and water heaters from another era. The right contractor renews all of it while respecting what makes the house worth keeping — and does it as one team, so the repipe and the restoration don’t work against each other.
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 South Pasadena, CA
Our South Pasadena work centers on vintage-home renovation: renewing the infrastructure while preserving character. We perform full repipes, water heater replacements, and gas line work — in-house under our C-36 license — and pair that work with kitchen and bathroom remodels designed to suit the home’s era. Because the same team handles the pipes and the finishes, the new plumbing disappears behind walls restored to match the home’s original detail.
Sewer and drain work is a frequent need in a city of older homes. We provide camera inspection for accurate diagnosis, hydro jetting to clear lines, and trenchless sewer repair that rehabilitates a failing lateral without tearing up established gardens or mature trees — a genuine concern in the City of Trees. Our sewer lining carries a 20-year warranty.
HVAC upgrades round out the infrastructure picture: we install, replace, and repair air conditioning and heating systems in homes where the existing equipment is undersized, inefficient, or simply worn out. We also build room additions that respect the home’s architecture — primary suites, expanded kitchens — and ADUs through our sister brand ADU Cities (100+ built in four years) for multigenerational family or guest housing.

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 home, walk through the project with you, and provide a written estimate. In vintage homes, we assess plumbing, sewer, and HVAC conditions alongside the visible scope so the estimate reflects the home’s real needs.
Will a renovation damage my home’s historic character?
No — that’s the opposite of our approach. Infrastructure work happens behind walls and in mechanical spaces; visible finishes are restored to suit the home’s character. One team handling both sides keeps the result coherent.
Do you handle plumbing or sewer emergencies?
Yes. Our sister brand 911 Drain Lines provides 24/7 drain and plumbing emergency service at 714.746.7611.
Which trades do you handle in-house?
General construction and remodeling, plumbing, drain and sewer, and HVAC, all under our own licenses. Electrical work is performed by qualified licensed electricians we bring in, since we do not hold the C-10 electrical classification.
