ADU Company in Brea, CA
Kitchen remodeling in Brea usually means working inside a mid-century ranch or a newer Carbon Canyon hillside home, and the difference between those two jobs is everything. Flat-lot ranches in 92821 and 92823 often need walls opened to fix old galvanized plumbing and undersized electrical panels, while hillside kitchens demand structural care when exterior walls come down. We handle both paths under one contract, from demo through cabinet install and finish trim. Call (833) 589-8273 to schedule a free estimate.
Why Brea Homes Are Different
Brea sits at the meeting point of flat Orange County tract housing and the steep foothills of the Chino Hills. The central and southern parts of town, largely in ZIP 92821, were built out in the 1950s and 1960s with ranch-style homes on narrow lots. Many of those kitchens still run on the original 100-amp electrical service, which limits appliance choices until the panel gets upgraded. The northern 92823 hills are another world entirely: custom homes on sloped pads, some dating to the 1980s and 1990s but many built in the last two decades. When we open walls in those houses, we’re often working with engineered shear walls and post-tension slab foundations that require different tooling and more careful anchor work than a flat-lot ranch.
Santa Ana winds and foothill heat shape material choices here. Exterior walls and window openings need proper flashing and air sealing, because a Brea kitchen with a south-facing wall can see indoor temperatures spike fast. Winter rains on hillside lots make drainage outside the kitchen wall a real concern, especially where a remodel bumps out an exterior wall. And Brea’s oil-field history adds a layer most cities don’t deal with: some properties sit over old well casings or methane zones, which must be checked before we pull permits for any foundation-touching work.
Our Main Brea Services
Brea homeowners call us most often for two projects: building an ADU in a backyard or converted garage, and remodeling an outdated bathroom. Both require permits, both reward careful planning, and both benefit from a contractor who knows this city’s specific lot configurations and inspection expectations.
ADU Builders in Brea
Garage conversions and backyard ADUs are common across Brea because so many older lots have detached garages and skinny side yards. The job looks different in the flats than in the hills: a garage conversion in 92821 is often a straightforward remodel inside an existing footprint, while a backyard ADU in the 92823 hills may need retaining walls, stepped footings, and an engineered foundation. We compare prefab brands like Boxabl and Plant Prefab against site-built framing, then handle utilities, interior finishes, and the final inspection. ADU Builders in Brea
Bathroom Remodeling in Brea
Brea bathrooms in older ranch homes tend to be compact, often 40 to 60 square feet, with tile set on mortar beds and cast-iron tubs that test a two-person crew’s patience on demo day. Hillside homes may have bigger bathrooms but more complications: sloped slab floors, window placement on sheer walls, and waterproofing demands that matter when winter rains come. We gut to the studs, correct framing and plumbing issues, waterproof properly, and finish with tile, glass, and fixtures under one contract. Bathroom Remodeling in Brea

Kitchen Remodeling in Brea
Kitchen remodeling in Brea is the highest-impact upgrade we do, and the city’s housing stock makes every job a little different. A 1960s ranch kitchen in 92821 typically needs panel upgrades, plumbing replacement, and layout rethinking inside a tight footprint, while a hillside kitchen in 92823 often means working around structural walls and sloped floors. Both benefit from the same approach: open walls once, fix what’s behind them, then rebuild with materials that handle Brea’s heat and occasional wind-driven rain. Our in-house team handles the entire job so you’re not coordinating a general contractor and a cabinet installer separately. You can also explore our full service detail on our Kitchen Remodeling page.
Cabinet and Countertop Replacement
Signs you need it
Face frames pulling from the wall, drawer slides that skip, and laminate counters peeling at the seams mean the kitchen has outlived its original cabinetry.
What it costs in Brea
Cabinet and countertop replacement in Brea typically runs $18,000 to $35,000 depending on cabinet grade, counter material, and whether we’re keeping the existing layout.
How we do it
We remove old cabinets and countertops after shutting off water and disconnecting fixtures, inspect and repair the wall framing behind them, install new cabinets level and anchored to studs, template and set countertops, then reconnect plumbing and mount hardware.
Full Kitchen Gut and Rebuild
Signs you need it
A floorplan that does not work for how you cook, water damage under the sink, or the desire to move plumbing and appliances to a new wall means a full gut, not a facelift.
What it costs in Brea
A full kitchen gut and rebuild in Brea falls between $35,000 and $65,000, with hillside homes in 92823 sometimes pushing higher when structural changes and panel work are involved.
How we do it
We strip the room to the studs, relocate plumbing and electrical to match the new floorplan, reframe any openings that need structural work, insulate and drywall, then install flooring, cabinets, counters, tile, and fixtures in sequence.

Figures above represent typical completed-project pricing in Brea, including materials, labor, and standard finish levels. Hillside access, seismic anchoring, and panel upgrades add cost on specific lots.
How long does a kitchen remodel take in Brea?
A cabinet-and-countertop replacement takes 2 to 3 weeks, while a full gut with layout changes runs 6 to 10 weeks depending on inspections. Permits in Brea add about a week at the start, and hillside jobs can stretch timelines when excavation or structural retrofits appear.
Call (833) 589-8273 for an exact quote. Estimates are free.
Will the price change once work starts?
The price changes only if we open a wall and find something no one could have predicted, and in Brea that most often means old termite damage, undersized plumbing, or electrical panel deficiencies in ranch homes. We walk through a written change order before any additional cost.
