Lake Elsinore has grown from a quiet lakeside town into one of the fastest-growing cities in Riverside County, and its housing tells that story. Most of the homes here are tract construction from the last few decades — built for families, commuters, and anyone who wanted more house for the money near the lake. That growth creates specific construction demand: floor plans that need to stretch as families grow, builder-grade finishes past their prime, and mechanical systems working overtime through long Inland Empire summers. When you need a contractor here, it pays to hire one team that can handle the whole project — the addition, the plumbing inside it, and the air conditioning that has to keep up with the extra square footage.
Construction & Remodeling Services in Lake Elsinore, CA
A lot of Lake Elsinore homes were built fast during boom cycles, and boom-cycle construction has a pattern: kitchens with dated cabinets and tile counters, bathrooms with fiberglass tub-shower combos, and HVAC systems sized to a price point rather than to comfort. Mars Construction Industries Corp helps homeowners bring these houses up to the way they actually live now. Kitchen remodels are our most-requested project in newer suburbs — new cabinetry, stone counters, better lighting, and layouts that open into the family room. Bathroom remodels follow close behind, trading worn builder fixtures for walk-in showers, modern vanities, and plumbing that works the way it should.
Because Lake Elsinore keeps adding families, additions and ADUs are a big part of what we do here. A growing household that needs a fourth bedroom, a home office, or space for an aging parent doesn’t have to give up a lakeside neighborhood they love. We design and build room additions that tie into the existing roofline and structure, and we build detached and garage-conversion ADUs — over 100 in the last four years through our sister brand ADU Cities. Every addition or ADU we build gets the same multi-trade treatment: framing and finish carpentry under our B license, plumbing and gas lines under our C-36, and HVAC extended or upgraded under our C-20, all by one accountable crew.
Heat is the other defining fact of life in Lake Elsinore. Air conditioning isn’t a luxury here; it’s infrastructure, and older tract systems lose efficiency every year they run. We install, replace, and repair full HVAC systems, and we handle the plumbing side of the house too — water heaters, repipes where older pipe sections exist, gas lines for outdoor kitchens and fire features, and drain and sewer service from our 911 Drain Lines division, including camera inspections, hydro jetting, and trenchless sewer repair backed by a 20-year warranty.

Why Lake Elsinore Property Owners Choose Mars
The most common remodeling headache is a contractor who can frame walls but has to hand off the plumbing, then the HVAC, then the sewer line — and nobody owns the schedule. Mars holds four CSLB licenses in-house: A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC. That means the same company that pours your addition’s foundation runs the water and gas lines to it and sizes the air conditioning for the new space. There are no gaps between trades because there are no separate trades to coordinate.
We’ve been doing this with 30+ years of hands-on experience — three decades of residential and commercial work across Southern California. Mars Construction Industries Corp is licensed, bonded, and insured, CSLB #1138550, and carries SB-PW and SB(Micro) small-business certifications. One call gets you a straight answer, one crew, and one company accountable for the finished result.
