Big Bear Lake is mountain resort country — cabins, A-frames, and second homes that sit empty in shoulder seasons and work hard in winter. Mountain properties punish deferred maintenance: freeze-thaw cycles, snow loads, and plumbing that fails when nobody’s watching. Mars Construction Industries (CSLB #1138550) serves Big Bear Lake with four licenses in-house, so one accountable team handles the remodel, the repipe, the sewer line, and the heating system. Inland Empire: 909.325.0020.
Construction & Remodeling Services in Big Bear Lake, CA
Winter is the defining test for mountain homes. Our C-20 HVAC crew installs and services heating systems built for real cold, and we repair the ones worth saving. Because our builders and HVAC techs work for the same company, a furnace replacement that needs venting or ductwork changes doesn’t stall waiting on another trade.
Plumbing in the mountains is about freeze protection and age. We repipe cabins with modern materials, replace water heaters, run gas lines, and winterize systems for seasonal homes. Our 911 Drain Lines crews handle drain and sewer work too — camera inspection, hydro jetting, and trenchless repair backed by a 20-year lining warranty.

Why Big Bear Lake Property Owners Choose Mars
Most remodeling projects fail in the gaps between trades. The plumber roughs in before the framer is done, the HVAC sub never shows, and the homeowner ends up project-managing three companies that blame each other. We built Mars Construction Industries to eliminate that problem. We hold four CSLB classifications in-house — A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC — so the crew doing your addition is the same company doing your repipe and your HVAC changeout.
We’ve been at it with 30+ years of hands-on experience, working from our Orange County home base across Southern California. We’re licensed, bonded, and insured (CSLB #1138550), and our SB-PW and SB(Micro) certifications reflect a company built to do right by the communities we serve. When you hire Mars, you get one accountable team, one phone number, and one company standing behind the finished work.
Our sister brands extend that accountability: 911 Drain Lines for drain and sewer emergencies, ADU Cities for accessory dwelling units, Get Your Roof Certified for roof certifications, and Universal Inspect for inspection services. Whatever your property needs, there’s a Mars team for it.

Frequently Asked Questions
Our cabin sits empty part of the year. What should we worry about?
Freeze damage and slow leaks are the big two — a burst pipe or failed water heater can run for weeks unnoticed. We recommend winterization for seasonal shutdowns, modern freeze-resistant plumbing where it counts, and water heater replacement before failure rather than after. Walk us through the property and we’ll prioritize honestly in a written estimate.
Are you a licensed contractor?
Yes. Mars Construction Industries Corp holds CSLB license #1138550 with four classifications: A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC. We are licensed, bonded, and insured, and we hold SB-PW and SB(Micro) small-business certifications. You can verify any California contractor’s license status at cslb.ca.gov.
How does your estimate process work?
It starts with a conversation and a walkthrough of the project. We look at the full scope, identify what each trade will need to touch, and give you a written estimate with clear, combined pricing. Because our plumbers, HVAC techs, and builders all work for the same company, we price the whole job once instead of stacking separate subcontractor bids with separate markups.
Which trades do you keep in-house?
General construction and remodeling, plumbing, drain and sewer, and HVAC are all in-house under our four license classifications. When a project also needs electrical work, we coordinate with licensed electrical subcontractors so the work stays on one schedule under one accountable team.
Do you offer emergency service?
Yes. Our 911 Drain Lines brand runs 24/7 drain and plumbing emergency service at 714.746.7611. For sewer line emergencies, we can camera-inspect the line, clear it, and talk through repair options including trenchless repair and sewer lining backed by a 20-year warranty.
Do you build ADUs?
Yes. Through our sister brand ADU Cities, we’ve built more than 100 accessory dwelling units in the last four years. From detached backyard units to garage conversions, we handle the full build with the same in-house plumbing, HVAC, and general construction crews.
