Fast, Reliable General Contractor Across Brea
A general contractor in Brea handles the full scope of a residential project: permits, demolition, framing, plumbing, electrical, finishes, and final inspection, all under one accountable team. At Gold Star Contractors, we work across every Brea ZIP code, 92821, 92822, and 92823, and we know this city’s permit counter better than most. Whether you’re adding a room in the historic flats near downtown or building an ADU off Carbon Canyon Road, call (833) 382-8544 and we’ll walk the site with you before anyone picks up a hammer.
Why Gold Star Contractors Is Brea’s Preferred General Contractor Company
Brea homeowners keep calling us back for one simple reason: we coordinate the trades so you don’t have to. Our General Contractor team is built to run kitchens, baths, roofing, windows, fencing, and ADUs through a single project team, not five separate phone numbers. Noel Carranza, our owner, sets the standard himself: when the plan says Cambria on the island, the island gets Cambria, and the cabinet boxes get ordered to match. No handoff gaps between the guy who framed the wall and the crew that tiles it.
We’re no stranger to Brea project sites. We’ve pulled permits at the Civic Center, coordinated with the county on oil-well clearance, and scheduled inspections across the hills. Local knowledge like that saves you weeks, and it shows up in every quote we write. When a Brea homeowner asks about a remodel timeline, we answer with dates, not shrugs.
Styles & brands we work with
Construction Company in Brea
A Construction Company in Brea builds everything from a rear addition on a 1950s ranch to a detached shop on a half-acre lot in the hills. The work starts with a site walk, a scope document, and a permit path that matches your property’s actual conditions, not a generic checklist. In Brea, those conditions can include abandoned oil-well casings in the flats and Brownfield remediation reviews in the newer eastern villages. We handle both.
Home additions in Brea typically run $45,000 – $130,000. Garage conversions run $30,000 – $80,000. Full ADU construction lands between $90,000 – $220,000, depending on site work, utility runs, and whether you need county septic or well sign-off. Every quote we write includes those line items up front.
Permits and Site Work
Before we price a job, we pull the parcel history. That means checking for Union Oil-era infrastructure near downtown and confirming Title 24 seismic and energy requirements on hillside lots. It also means verifying setbacks for septic, wells, and outbuildings before we promise a foundation date.
Outbuildings, Shops, and Detached ADUs
On Brea acreage lots, we regularly scope detached structures that city-lot contractors never see: shops with concrete aprons, equipment storage, guest houses, and ADUs with separate utility services. The plan set needs grading and drainage details, not just a pretty elevation. We bring that from day one.
Remodeling Contractor in Brea
A Remodeling Contractor in Brea handles whole-home renovations, kitchen and bath overhauls, and structural repairs inside an existing footprint. That’s different from new construction: the house has history, the walls have surprises, and the permit office wants to know what you’re changing before you change it. We map all of that out first.
Kitchen remodels in Brea run $14,000 – $45,000, with cabinet installation at $4,000 – $13,000 and countertops at $2,000 – $6,500. Bathroom remodels land at $9,000 – $28,000, with tub-to-shower conversions at $3,500 – $10,000. If you’re breathing new life into a mid-century ranch near downtown, those numbers hold, but we account for old wiring and galvanized plumbing during the estimate, not after demolition.
Historic Flats and Mid-Century Ranches
Older Brea homes often hide original knob-and-tube wiring, cast-iron drain lines, and foundations that have shifted over 70 years. We scope those before quoting so the remodel doesn’t stall at rough-in. It’s not about surprise costs; it’s about honest numbers.
Hillside and Tract-Home Renovations
Newer Brea homes built in the 1990s and 2000s have their own quirks: stucco-and-tile assemblies that need proper flashing, attic ventilation that was undersized at original build, and HOA review on exterior changes. We manage those approvals as part of the job.
Trusted Brands We Service in Brea
Gold Star Contractors is authorized to specify and install materials from more than 50 vetted manufacturer brands. For Brea kitchen and bath projects, that includes Cambria, Caesarstone, and Silestone countertops; KraftMaid and Wellborn cabinetry; Kohler, Grohe, Toto, and Moen fixtures; and Schluter waterproofing systems. For exterior work, we install GAF, CertainTeed, and Owens Corning roofing; James Hardie siding; and PGT, CGI, and Therma-Tru windows and doors. When a Brea homeowner asks about an ADU, we can bring Abodu and Dvele prefab structures into the conversation. Premium materials, professionally installed, from one accountable contractor.
Common General Contractor Problems We See in Brea Homes
- Abandoned oil-well casings and sumps. In the older blocks near downtown, excavation for additions or pools regularly hits Union Oil-era infrastructure. We trigger the mandatory city and county review before concrete is poured, because skipping it gets you a stop-work order and a removal bill.
- Undersized attic ventilation and hot roofs. Brea summers exceed 95°F, and Santa Ana winds push heat into attic spaces fast. We spec radiant barriers, cool-roof retrofits, and fire-resistant exterior assemblies on hillside homes.
- Brownfield review complexity on hillside lots. Many eastern Brea communities sit on remediated Union Oil land. That means environmental clearance letters, Title 24 seismic checks, and specific grading rules before permits are issued.
- Septic and well setback surprises on acreage. On open lots, the county health department reviews septic and well placement before we can even finalize an ADU or shop foundation. We verify those early, because a rejection at plan check costs you months, not days.

AfterPricing for General Contractor in Brea, CA
Brea has two very different cost structures. In the flats, older homes carry hidden conditions that push remodel numbers up. In the hills, brownfield and grading requirements add site-work cost that city-lot contractors never see. Here’s what we quote, honestly, in this market:
| Project | Brea Price Range |
|---|---|
| ADU Construction | $90,000 – $220,000 |
| Home Addition | $45,000 – $130,000 |
| Garage Conversion | $30,000 – $80,000 |
What changes the number on acreage: haul distance for equipment, soil compaction, septic and well setbacks, and whether the parcel has oil-well clearance already documented. We scope all of that before quoting, and our estimates are free.

FAQs About General Contractor in Brea
Yes. Any ADU on unincorporated county land near Brea goes through county planning and the county health department, not just the city. Septic and well setbacks get reviewed before permits are issued, and a rejection at plan check can delay you 6 to 10 weeks. We pull the parcel history and flag every county requirement before we quote. Call (833) 382-8544 for a free estimate that accounts for all of it.
We stop work, notify the city and county, and wait for clearance before any concrete is poured. On a half-acre lot off Carbon Canyon Road, our crew was building a detached ADU when the septic excavation hit an abandoned oil-well sump from the Union Oil days. We triggered the review, redesigned the leach field setbacks, and adjusted the foundation. It added three weeks and a change order, but the final inspection passed clean. Skipping that review gets you a stop-work order.
An ADU in Brea typically runs $90,000 – $220,000. The spread reflects site conditions: flat city lots with utility access cost less than hillside acreage with soft soils, long hauls, and septic or well sign-off. We break out every site-work line item in the estimate so you can see exactly where the money goes. Call (833) 382-8544 for a written, line-item quote.
Yes. We regularly build detached shops, equipment storage, and guest structures on Brea acreage. The plan set has to address grading, drainage, access, and setbacks for any existing septic or well system. We handle the full permit package, including county review when the parcel requires it.
Projects in the historic downtown core face additional review for oil-era infrastructure, original wiring, galvanized plumbing, and foundation conditions. The city often wants a structural review before issuing permits, especially on pre-1960 bungalows and ranch homes. We know what that review requires and we build it into the schedule before you sign anything.
