ADU Company in Claremont, CA
Kitchen remodeling in Claremont means working with homes built anywhere from 1923 to 2024, and we approach each one according to what’s actually behind the walls. The Spanish Colonial bungalows near the Village tend to have plaster over wood lath, narrow door openings, and foundation settling that shifts cabinet lines. The mid-century ranches east of Towne Avenue have different problems: aging electrical panels, galvanized plumbing, and layouts designed for closed-off cooking. Add hot inland summers that punish cheap finishes and you get projects where the right prep work matters more than the cabinet style. Call us at (877) 265-5587 to talk through what your Claremont kitchen needs.
Why Claremont Homes Are Different
Claremont’s housing stock doesn’t follow a single pattern, and that shows up in every kitchen we open up. The 1920s and 1930s homes around the Claremont Colleges and the Village are among the oldest in the eastern San Gabriel Valley, built with balloon framing, true dimension lumber, and often settled foundations on the clay-heavy soils near the foothills. Those homes usually need structural reinforcement before new cabinetry goes in, or the countertops will never sit level. The ranch tracts built in the 1950s and 1960s toward the east side have slab foundations and more uniform framing, but they carry decades of DIY electrical work and original cast-iron drain lines that are at the end of their service life.
Climate shapes finish choices here more than people expect. Summer temperatures regularly pass 100 degrees in Claremont, and the UV load fades laminate, warps low-grade veneer, and breaks down cheap caulk lines around sinks and backsplashes. We spec cabinet finishes and countertop materials accordingly, and we pay close attention to ventilation, because a kitchen that can’t move hot air in August is miserable to work in. The occasional Santa Ana wind event also means we anchor range hood ducting and vent terminations to handle gusts that can reach 50 mph in the foothill canyons north of Baseline.
Our Main Claremont Services
Most Claremont homeowners reach out about two things: adding an ADU to a lot where the mature tree canopy and setback rules control the design, and remodeling a bathroom in an older home where the plumbing and waterproofing need serious attention before any tile goes up. Here’s what each involves here.
ADU Builders in Claremont
Detached ADUs in Claremont run into a challenge that’s specific to this city: the protected tree canopy. In the neighborhoods around the colleges, mature oaks and olives often dictate exactly where a unit can sit, sometimes with more authority than the zoning code. We work with arborists early, before foundation lines are set, so the ADU footprint fits around root zones and heritage tree rules instead of forcing a redesign later. The older Village-adjacent lots are also tight, which makes prefab systems from manufacturers like Abodu worth considering, they’re designed for narrow side yards and quick set days. ADU Builders in Claremont covers the full process from tree review through final inspection.
Bathroom Remodeling in Claremont
Bathroom remodels in Claremont’s 1920s and 1930s homes often start with what’s hiding under the tile: original cast-iron waste lines, failing mud-set floors, and shower pans that have been leaking into the subfloor for years. In the mid-century tracts, we see galvanized supply pipes that restrict flow and old shower valves that are no longer code-compliant. Because the housing stock is so mixed, we never assume a bathroom has modern framing or waterproofing until we open it up. We handle the full scope, demo, plumbing replacement, waterproofing, tile, glass, and finish carpentry, so the project doesn’t stall between trades. Bathroom Remodeling in Claremont explains the process and what to expect in an older Claremont home.

Kitchen Remodeling in Claremont
Kitchen remodeling in Claremont is shaped by three local realities: homes built across a 100-year span, summer heat that tests every material choice, and neighborhoods where mature trees and tight lots limit exterior work. The oldest kitchens near the Village were built for a different era, small, closed off, and wired for appliances that drew a fraction of today’s load. The mid-century and later homes have more space but often carry deferred maintenance that has to be addressed before new cabinets and counters go in. We approach every job by opening the walls first, because what we find determines the right sequence and budget. For the broader picture on how we handle kitchen work, see our Kitchen Remodeling service overview.
Full Kitchen Renovation
Signs you need it
The layout no longer works for how you cook, the cabinets are delaminating or the drawer slides are failing, and the electrical system can’t support modern appliances without tripping breakers.
What it costs in Claremont
A full kitchen renovation in Claremont typically runs $45,000 to $95,000 depending on scope, with structural work on older homes pushing the number toward the upper end.
How we do it
We open the walls to inspect framing, plumbing, and electrical, then rebuild in sequence: structural and rough-in work first, drywall and flooring next, then cabinetry, counters, backsplash, and finish plumbing and electrical.
Cabinet Replacement and Refacing
Signs you need it
Cabinet boxes are still solid but doors and drawer fronts are worn, warped, or outdated, and the layout itself works fine.
What it costs in Claremont
Cabinet replacement in Claremont generally runs $12,000 to $30,000, while refacing existing boxes with new doors and veneer typically falls between $8,000 and $18,000.
How we do it
We measure every opening precisely, order or build the new faces, then install doors, drawers, hinges, and hardware while keeping the kitchen functional throughout.
What Kitchen Remodeling Costs in Claremont
| Item | Typical range in Claremont |
|---|---|
| Full kitchen renovation | $45,000 – $95,000 |
| Cabinet replacement | $12,000 – $30,000 |
| Cabinet refacing | $8,000 – $18,000 |
Homes built before 1940 tend to land on the higher end because we’re rebuilding framing, leveling floors, and replacing old drain and supply lines before finish work starts. We give you a written line-item quote before we start, and that number does not change unless you change the scope.
Can you remodel a Claremont kitchen without moving load-bearing walls?
Yes, and most of our Claremont remodels keep the original footprint and work within it. We can move non-load-bearing partitions, relocate appliances, and reconfigure storage without structural changes.
How long does a full kitchen remodel take in Claremont?
A full kitchen remodel here typically takes 6 to 10 weeks from demo to final cleanup. Older homes with structural work or plumbing replacement run longer, and permit review in Claremont adds roughly two to four weeks before we start.
Brands We Service in Claremont
We work across the systems Claremont homeowners ask about most: Plant Prefab and Abodu for modular ADUs, Tuff Shed for the most cost-efficient permitted conversion path, and James Hardie fiber cement for exterior finishes that hold up through Inland Empire summers. Our brands page explains the trade-offs between each system, and we’re glad to walk you through which one fits your lot and timeline.

Prices in Claremont climb when the home is pre-1940, when protected trees force foundation design changes, or when the lot slopes enough to need retaining walls and custom grading. Every project gets a fixed written quote before work begins, and we don’t issue change orders for things we should have caught in the estimate.
Neighborhoods We Serve in Claremont
We work throughout Claremont, and the neighborhoods each bring their own conditions. The Village and the streets around the Claremont Colleges have the oldest homes and the tightest tree constraints. The ranch tracts east of Towne Avenue are more uniform but often carry deferred electrical and plumbing work. The foothill lots north of Baseline run into slope and drainage challenges. Wherever you are in Claremont, we schedule estimates within a few business days and start work on a written timeline.

What Claremont Customers Say
"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
— Steve Mercer"Unit came out great and the tenant is happy. The timeline ran long, largely because of how slow the city was on plan check, though a couple of the delays were scheduling on their end."
— Marcy Miller"Garage conversion to a one bedroom unit. He handled the plans, the city submittal, and every round of corrections. Took six months from first meeting to final inspection and he never once made the permit process my problem."
— Beatriz Morales
