Sierra Madre is a foothill village in the truest sense — a small city of historic homes, tree-lined streets, and a close-knit downtown, set against the San Gabriel Mountains. Many of its houses date to the early and mid-20th century, and they carry the character homeowners here want to preserve: original woodwork, vintage tile, established gardens. But beneath that character, the infrastructure is often original too — aging supply lines, old sewer laterals, water heaters and furnaces past their prime, and kitchens and baths designed for another era. Renovating here takes a contractor who respects the home’s character and can still renew everything behind the walls — ideally the same team doing both.
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 — so a Sierra Madre renovation renews the infrastructure and the finishes together, under one contract.
Construction & Remodeling Services in Sierra Madre, CA
Our Sierra Madre work is built around historic-home renovation done right: infrastructure first, character preserved. 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 that respect the home’s vintage feel while delivering modern function. Opening walls once to renew plumbing and deliver new finishes together is the efficient way to renovate a historic home, and it avoids the all-too-common sequence of a beautiful remodel followed by emergency pipe work.
Sewer and drain work is a regular need in a city of older homes. We provide camera inspection to diagnose problems accurately, hydro jetting to clear lines, and trenchless sewer repair that rehabilitates a failing lateral without tearing up established landscaping — a real consideration on Sierra Madre’s mature lots. Our sewer lining carries a 20-year warranty.
Foothill weather makes HVAC a genuine concern: hot summers, cold winter nights, and older homes with inadequate or failing systems. We install, replace, and repair air conditioning and heating systems, sized for the home as it exists today. We also build room additions that blend with historic architecture, and ADUs through our sister brand ADU Cities — more than 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 historic homes, we assess infrastructure — plumbing, sewer, HVAC — alongside the visible scope so the estimate reflects the real condition of the house.
Can you preserve my home’s character during a renovation?
Yes. We renovate with the home’s character in mind — matching trim profiles, preserving vintage details where possible — while bringing plumbing, gas, and HVAC fully current behind the scenes. 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.
