Gardena is south bay living without the pretense — diverse, hardworking neighborhoods of postwar homes, busy commercial corridors along Rosecrans and Western, a community where contractors earn reputations one honest job at a time. The housing stock is older and the commercial strips are active, so Gardena needs a contractor comfortable in both worlds: the 1950s home needing a repipe and the retail space needing a build-out.
Mars Construction Industries Corp brings 30+ years of hands-on experience to both sides of that line. Four CSLB licenses in-house — A General Engineering, B General Building, C-36 Plumbing, C-20 HVAC (Lic. #1138550) — so the residential repipe, the restaurant TI, the sewer lateral, and the HVAC replacement all come from one licensed, bonded, and insured team. One detailed written estimate, one project manager, straight dealing.
Construction & Remodeling Services in Gardena, CA
Gardena’s postwar homes tell the familiar infrastructure story: galvanized supply lines past their prime, cast-iron drains, sewer laterals never camera-inspected. We lead with diagnostics — video inspection of the lateral, honest assessment of the supply plumbing — because recommendations should have evidence. Our C-36 crews handle whole-home repipes, water heaters, and gas lines in-house, and trenchless lining with our 20-year warranty renews failing laterals without tearing up the property. The commercial corridors are the other half of our Gardena work: retail build-outs, restaurant interiors, and office TI where our in-house plumbing and HVAC keep restroom rough-in, kitchen plumbing, and mechanical work on schedule.
Residential remodeling rounds it out: budget-honest kitchen and bath renovations, room additions under our A and B licenses, and ADUs — 100+ built in four years through ADU Cities — for multigenerational households. Our C-20 crews keep HVAC honest: repair when there’s life left, right-sized replacement when there isn’t. And 911 Drain Lines answers 24/7 at 714.746.7611.

Frequently Asked Questions
Do you take on commercial work?
Absolutely — offices, retail, restaurants, and light industrial/warehouse interiors. We’re licensed, bonded, and insured for commercial work with SB-PW and SB(Micro) certifications, and in-house plumbing and HVAC keep TI schedules tight.
Are you licensed to do this work?
Yes. Mars Construction Industries Corp holds CSLB #1138550 — A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC. We’re licensed, bonded, and insured, with SB-PW and SB(Micro) certifications. Verify any California contractor at cslb.ca.gov — we encourage it.
Do you handle every trade in-house?
The trades that matter most — building, plumbing, HVAC — are our own licensed crews under CSLB #1138550. For specialty scopes outside our four licenses, we bring in vetted specialists and manage them. Either way, you deal with one accountable team and one point of contact.
We need a restaurant build-out on a commercial corridor. Can you handle the kitchen mechanical work?
Yes — restaurant TI is core work for us. Our C-36 crews handle kitchen plumbing, drainage, and gas lines for cooking equipment in-house, and our C-20 crews handle HVAC and ventilation. Both trades ours means the kitchen mechanical scope stays on our schedule. We’ll walk the space and give you a detailed written estimate with a realistic sequence to your opening.
