Fast, Reliable General Contractor Across Brea
Hiring a general contractor in Brea means finding a team that understands this city isn’t one thing. The 92823 hills demand one kind of engineering, while the 92821 and 92822 flats on the old Brea-Olinda basin floor demand another. We’ve worked both. San Mateo Construction brings a single accountable crew to every system in your home, from roofline to foundation, so you aren’t juggling five separate vendors during a kitchen tear-out or a hillside addition. If you’re planning a remodel, an ADU, or exterior work in Brea, call (855) 901-7266 to have us walk the site and price it honestly.
Why San Mateo Construction Is Brea’s Preferred General Contractor Company
We built our reputation in Brea by knowing the difference between a flatland lot and a slope. A contractor who only works the flats will underestimate the brush-clearance sign-off above Carbon Canyon. One who only works the hills will overbuild on Imperial Highway. Our crew lives in both realities. On 92823 hillside homes we sequence fire-department inspections weeks before framing on a deck rebuild. On a 1960s tract home in 92821 we see the same adobe clay heaving driveways every summer and we plan subgrade for it from day one.
Noel Carrington, who leads San Mateo Construction, set the standard for us here: quote the soil, quote the access, quote the permit path. Brea homeowners call us because they’ve watched neighbors get stuck with cracked slabs six months after a cheap driveway pour, or lose two months to a stop-work order because nobody told the neighbors about shared-wall work. We don’t win every bid, and that’s fine. We win the jobs where the homeowner wants the site left clean, the permits pulled correctly, and the trade schedule kept under one accountable roof.
Styles & brands we work with







General Contractor Services in Brea
General Contractor Services in Brea often start with a simple question: what’s holding this house together, and what’s failing? For us that question splits by elevation. A whole-home remodel in 92822 on a slab foundation means checking for hairline cracks that trace the clay’s swell cycle. A home addition below the Puente Hills in 92823 means engineering for slope stability and drainage before a single footing is poured. We price both accurately because we’ve done both repeatedly.
Whole-Home Remodel on the Flats
Older tract housing in 92821 and 92822 carries original 1960s-70s framing, outdated plumbing stacks, and undersized electrical panels. We sequence kitchens, baths, and flooring so your family can stay in the house as long as possible. Kitchen remodels in Brea typically run $14,000 – $45,000 depending on structural work, cabinet brand, and whether we’re moving walls.

Hillside Addition and Hardscape
On 92823 slopes, retaining walls and drainage aren’t afterthoughts; they’re the budget. A home addition in Brea’s hills routinely lands between $45,000 and $130,000 because of the engineered foundation and WUI-compliant materials. We handle the fire department sign-off and brush-clearance paperwork so you aren’t doing it piecemeal.

Construction Company in Brea
Calling a Construction Company in Brea usually means the job is too big for a handyman and too complicated for a trade-by-trade scramble. That’s where we fit. Roof replacement, window replacement, driveway replacement, and room additions all trigger Brea’s permit review. We pull the permits, call the inspections, and keep the schedule moving. Roof replacement with GAF or Owens Corning materials in Brea generally falls between $8,000 and $20,000.
ADU and Garage Conversion
Brea’s garage conversion and ADU rules have tightened as the city pushes for more housing stock. An ADU here runs $90,000 – $220,000. A garage conversion is $30,000 – $80,000. We won’t promise a number without walking your lot, because access and the existing slab condition swing the price more than any line item in a brochure.
Driveway and Hardscape Replacement
Flatland driveways in Brea fail early because nobody engineered the base for expansive adobe clay. We’re not the cheapest driveway crew in north Orange County. We’re the one that reuses the job with a deeper aggregate lift and control joints so the concrete doesn’t crack the first summer. Paver driveway installation in Brea is $7,000 – $18,000; concrete runs $4,500 – $12,000.
Trusted Brands We Service in Brea
We stock and install James Hardie siding for Brea homes because it handles Santa Ana heat and ember exposure far better than wood lap. For ADU and prefab work we work directly with modern manufacturers like Boxabl and Plant Prefab, which most traditional remodelers in Orange County can’t even quote. On kitchen and bath work you’ll choose from Cambria or Caesarstone countertops, not whatever the cabinet shop happened to have on the loading dock. We help you choose across premium and value tiers so the math works for your street, whether you’re near Brea Mall or up Birch Street toward the hills.

AfterCommon General Contractor Problems We See in Brea Homes
Brea’s mix of hillside and flatland homes creates a very specific set of failure modes. Here’s what we see most often on 92821, 92822, and 92823 properties:
- Expansive clay heave on flatland slabs. Winter rain swells the adobe soil; summer dry-out shrinks it. A slab poured without a compaction plan and moisture barrier cracks within one season. We fix the subgrade before we ever discuss a finish surface.
- WUI brush-clearance delays on hillside remodels. In 92823 above Carbon Canyon, we coordinate brush-clearance inspection with the fire department before final sign-off. Miss this and the final inspection fails, adding weeks to your schedule.
- Shared-wall and party-wall disputes on tight lots. Brea’s older tract streets run lot line to lot line. If your foundation or driveway work touches the neighbor’s property line, Brea requires written notice. We prepare that. Ignoring it gets a stop-work order.
- Stormwater drainage that damages hillside foundations. Concentrated winter storms running down the Puente Hills scoured foundations and undercut decks on homes built before modern drainage codes. We grade and divert first, then build.
Pricing for General Contractor in Brea, CA
Every Brea quote starts with a site walk, because square footage alone tells you nothing about clay content, street access, or the fire department’s brush rules. That said, you deserve real starting numbers before you spend a weekend calling around. In Brea, expect the following ranges for our most common scopes:
| Project | Typical Brea Range |
|---|---|
| Kitchen Remodel | $14,000 – $45,000 |
| Bathroom Remodel | $9,000 – $28,000 |
| Home Addition | $45,000 – $130,000 |
| ADU Construction | $90,000 – $220,000 |
| Roof Replacement | $8,000 – $20,000 |
What shifts the number? Access. A steep 92823 driveway that can’t fit a concrete truck costs more in labor. A flat 92821 lot with alley access costs less. We quote written line items, no change orders unless you approve the extra in writing, and fixed pricing on the approved scope. Call (855) 901-7266 to schedule your free estimate.

FAQs About General Contractor in Brea
It raises it, and if you ignore it, it raises it again next year. Brea’s flatland properties in 92821 and 92822 sit on expansive adobe clay that swells with winter rain and shrinks in summer heat. We engineer every slab and driveway with a deeper aggregate base and control joints. A concrete driveway replacement here runs $5,000 – $14,000 because that subgrade work is non-negotiable. Call (855) 901-7266 for an exact number on your lot.
A hillside addition in Brea’s 92823 typically requires building permits, a soils report, slope-stability review, WUI brush-clearance inspection signed off by the fire department before framing, and final building inspection. We sequence the fire department visit early so it doesn’t block your schedule. If you move dirt on a steep lot, a grading permit may also apply. We manage the entire permit chain under our General Contractor license.
We park our own vehicles off-site when the street is narrow, and we stage materials in a neighbor-approved location before demolition starts. For shared-wall or lot-line work, Brea requires written notice to the adjacent owner. We draft that notice and deliver it ourselves. If a driveway is shared, we schedule concrete pours on a day the neighbor agreed to keep the access clear. That’s how we keep a constrained site clean and the neighbors onside.
Yes, every time. Once we’re inside a wall in a 1960s Brea tract home, we might find old galvanized plumbing or asbestos tape no one could see during the estimate. You’ll get a written change order for the added scope before we do the work. If a contractor won’t put a change in writing, that’s a red flag. We operate on fixed pricing for the approved scope and written approval for everything else.
Six to ten weeks, assuming no structural surprises. Brea’s 1950s-70s kitchens often hide undersized studs, cheap original plumbing, and 100-amp panels that need upgrading before the new appliances can pass inspection. We front-load the permit and rough-in schedule to avoid stop-and-start pacing. If you want a hard timeline for your specific address, call (855) 901-7266 and we’ll walk the house and give you a week-by-week plan.
