Long Beach is a major port city with some of the most distinctive historic neighborhoods in Southern California — Craftsman bungalows, Spanish Revival homes, and early-20th-century districts — alongside downtown towers, beach-adjacent condos, and working commercial corridors. That combination makes it one of the most varied construction markets in the county: vintage homes needing repipes, sewer laterals, and careful renovation; beach-area properties dealing with salt air on HVAC and exteriors; and a downtown that generates constant commercial tenant improvement. A contractor working Long Beach needs range — and the licenses to back it up.
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 — from a bungalow repipe to a downtown build-out.
Construction & Remodeling Services in Long Beach, CA
Our Long Beach residential work starts with the historic neighborhoods. We renovate Craftsman and vintage homes with respect for their character — renewing infrastructure while preserving original detail — and we perform the repipes, water heater replacements, and gas line work these homes need, in-house under our C-36 license. Kitchen and bathroom remodels in older homes get the same treatment: new finishes over new plumbing, planned as one project so walls open once.
Sewer and drain work is a defining need in a city with this much early-20th-century housing. We provide camera inspection for accurate diagnosis, hydro jetting to clear lines, and trenchless sewer repair that rehabilitates failing laterals without tearing up established landscaping or historic hardscaping. Our sewer lining carries a 20-year warranty. For homeowners facing a sewer problem under a 1920s bungalow, trenchless is often the difference between a manageable project and a major excavation.
Near the coast, salt air wears on HVAC equipment and exteriors — we install, replace, and repair air conditioning and heating systems, including units damaged by marine exposure. We build room additions and ADUs for the city’s growing and multigenerational households; through our sister brand ADU Cities, we’ve built more than 100 ADUs in four years. And downtown and the commercial corridors keep us busy with tenant improvement: office, retail, and restaurant build-outs with plumbing and HVAC in-house under one contract.

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. In historic homes, we assess infrastructure — plumbing, sewer, HVAC — alongside the visible scope so the estimate reflects the home’s real condition.
Can you renovate my historic home without damaging its character?
Yes. Infrastructure renewal happens behind walls and in mechanical spaces; visible finishes are handled with the home’s character in mind. One team doing both keeps the result coherent.
Do you handle both residential and commercial work?
Yes — from bungalow remodels and repipes to downtown tenant improvements, with plumbing, drain, and HVAC in-house for both.
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.
