Placentia keeps a small-town feel in north Orange County — the historic Bradford district’s early-1900s homes, then mile after mile of family tracts from the postwar boom through the 1980s. That layered housing stock is a perfect argument for a multi-trade contractor: the Bradford-district cottage needs a careful repipe and maybe a sewer lateral; the 1970s tract needs a kitchen remodel, new HVAC, and possibly an ADU for aging parents.
Mars Construction Industries Corp serves Orange County, backed by 30+ years of hands-on experience from our office in the city of Orange, minutes from Placentia. Four CSLB licenses in-house — A General Engineering, B General Building, C-36 Plumbing, C-20 HVAC (Lic. #1138550) — so historic-home plumbing or full tract-home renovation, one licensed, bonded, and insured team handles every trade under one estimate and one project manager.
Construction & Remodeling Services in Placentia, CA
In the Bradford district and Placentia’s oldest streets, our work centers on infrastructure renewal with respect for the architecture: whole-home repipes routed to protect original finishes, sewer camera inspections showing the lateral’s condition on video, and trenchless lining with a 20-year warranty that avoids excavating established landscaping. Through the tract neighborhoods, the pattern is familiar — original kitchens and baths ready for renovation, aging supply lines due for replacement, HVAC systems in their second decade. Our plumbing and HVAC crews are in-house, so a whole-home refresh becomes one coordinated project with one schedule instead of three contractor hunts.
Placentia’s family demographics drive steady ADU demand — 100+ built in four years through ADU Cities — giving multigenerational households real breathing room as a single design-build package. And our C-20 crews replace tired HVAC before the next heat wave, while 911 Drain Lines answers drain emergencies 24/7 at 714.746.7611.

Frequently Asked Questions
Will I deal with several contractors?
No — that’s the point of hiring us. One project manager, one schedule, one company accountable for the finished work. Most projects never need an outside trade; when they do, we coordinate them.
How does your estimate process work?
Call 310.880.9718 or email brett@marsx.construction. We’ll walk the property, look at actual conditions, and give you a detailed written estimate spelling out scope, materials, and expectations. No pressure, no vague allowances — you know exactly what you’re buying before work starts.
Do you offer emergency service?
Yes. 911 Drain Lines runs 24/7 for drain and plumbing emergencies at 714.746.7611. For urgent construction issues, call 310.880.9718 and we’ll get the right crew moving.
Our tract home still has its original 1970s plumbing. Should we repipe before remodeling the kitchen?
Usually yes — and the order saves real money. If the remodel opens walls anyway, that’s the ideal moment to replace aging supply lines: our C-36 crew repipes while our building crew has the walls open, under one schedule. We’ll camera your drains and assess the plumbing during the estimate and give you an honest sequencing recommendation.
