Fast, Reliable General Contractor Across Claremont
Finding a General Contractor in Claremont who understands what older homes actually hold behind the walls changes everything about how a remodel goes. We do. A full-scope remodel or addition in Claremont typically runs $45,000 – $130,000 depending on scope, and the condition of what we find once walls are open drives more of that number than most homeowners expect. That’s exactly why we inspect first, write allowances into the contract, and get every change order signed before we touch the work.
We’re Moreno Valley Builders, and our General Contractor team works throughout Claremont, from the Village to the south-side ranch tracts. We manage the trades so you don’t have to. Call (877) 752-3154 for a free estimate on your project.
Why Moreno Valley Builders Is Claremont’s Preferred General Contractor Company
Claremont homeowners tend to ask sharper questions than most. Living among the Claremont Colleges means a lot of people here work in or around institutions that value documentation, clear process, and accountability. We match that. Our crews know the difference between a 1920s Craftsman near Memorial Park and a 1960s ranch off Mills Avenue, because each one fails differently and each one needs a different approach when we open it up.
We’re a licensed general contractor, and we carry the full project from permits through final inspection. One contractor. Every phase. When you call, you get a straight answer on whether your scope makes sense, what the discovery phase will likely turn up given your home’s era, and what we’d write as allowances before a single wall comes down. Call (877) 752-3154 and tell us what you’re planning.
Styles & brands we work with







Construction Company in Claremont
As a Construction Company in Claremont, we take on the structural work other contractors refer out: additions, load-bearing wall removals, garage conversions, and full interior re-framing on homes that were never built to modern code. A home addition in Claremont runs $45,000 – $130,000, and a garage conversion lands between $30,000 and $80,000. The condition of your existing framing, foundation, and electrical service drives the final number, and we’ll tell you that before we start, not after.
Additions and structural scope
Claremont’s older stock means additions usually tie into framing that predates current seismic and shear standards. We plan for that. Our scope letters spell out exactly where new structure meets old, and we bring in the structural engineer early so the permit set doesn’t bounce back from the city with corrections.
Garage conversions and ADUs
An ADU in Claremont runs $90,000 – $220,000. The city’s lot sizes and setback rules make detached units more common here than in nearby Montclair or Upland, and we handle the site work, utility runs, and foundation pour as one accountable team. We also work with prefab ADU systems from companies like Abodu and Dvele, including the Claremont Abodu service, when a faster off-site build makes sense for your lot.
Remodeling Contractor in Claremont
As a Remodeling Contractor in Claremont, we focus on kitchens and baths in homes where nothing is square and nothing was built to the dimensions of modern cabinetry. A kitchen remodel in Claremont runs $14,000 – $45,000; a bathroom remodel runs $9,000 – $28,000. Those numbers reflect what we consistently see here: plaster repair, electrical corrections, subfloor flattening, and waterproofing done the way it should have been the first time.
Kitchen remodels in older Claremont homes
We specify KraftMaid and Wellborn cabinetry because their semi-custom lines let us build around the odd wall depths and ceiling heights common in Craftsman homes off Indian Hill Boulevard. Countertops from Cambria and Caesarstone give you surface options that hold up to Claremont’s intense summer sun through south-facing kitchen windows.
Bathroom remodels with real waterproofing
On the south-side ranch tracts, we regularly find shower pans that never got a proper waterproofing membrane. We strip those to the studs, install Schluter or similar bonded waterproofing systems, and tie the plumbing fixture selection into brands like Kohler, Toto, and American Standard so you’re choosing from proven products, not contractor convenience picks.
Trusted Brands We Service in Claremont
Your project. Your material choices. We work with over 50 name-brand manufacturers across cabinetry, countertops, plumbing, roofing, windows, hardscaping, and prefab/ADU systems. In Claremont, we regularly specify Toto and American Standard for period-appropriate bath fixtures on Village-area remodels, and Sterling for budget-tier options on rental and ADU work. Because we stock common parts locally and maintain direct distributor relationships, product lead times on Claremont jobs tend to run shorter than they do for contractors working through retail channels.

AfterCommon General Contractor Problems We See in Claremont Homes
- Knob-and-tube wiring hiding behind plaster walls. Homes built before 1930 near the Claremont Village often still carry it, spliced into newer runs in ways that violate current electrical code. Once a wall is open, the permit requires us to address it, so we write an electrical allowance into every pre-1940 remodel contract.
- Undersized framing under load-bearing headers. We see it on both Craftsman-era homes and 1950s ranch builds where a previous owner “opened up” a wall without an engineer. We stop, size the member properly, and get the structural repair into a signed change order before proceeding.
- Failed waterproofing on south-side ranch homes. Shower pans built without membranes, window flashings that leaked for a decade, and subfloor rot under bathrooms. Claremont’s dry climate masks these failures longer than coastal fog would, so they’re often worse by the time we find them.
- Preservation review on Village-area exteriors. Exterior remodels and additions near the Colleges get scrutinized for period-appropriate detailing. Our scope of work on a Craftsman near the Village often includes trim profiles and porch detailing matched to the original, not just structural work, because the review process demands it.

What moves these numbers in Claremont is what we find during discovery. A 1910s Craftsman near the Village with original electrical and plaster will cost more than a 1960s ranch with a clean crawlspace, because the permit triggers code upgrades on the older home. We write allowances into the contract up front, and every surprise gets priced and approved in writing before we touch it. Call (877) 752-3154 for a line-item estimate on your specific project.

FAQs About General Contractor in Claremont
Because Claremont’s housing stock is old enough that what’s behind the walls rarely matches the visible finishes. Knob-and-tube wiring, undersized framing, and failed waterproofing are common on both the Craftsman homes near the Village and the 1950s ranch tracts on the south and east sides. We handle this by inspecting first, writing specific allowances into the contract, and getting every discovery priced and approved in writing before work proceeds. Call (877) 752-3154 and ask us what we’d expect to find in your home’s era.
Yes, and in Claremont it matters more than in most nearby cities because Village-area and college-adjacent exterior work goes through preservation-minded review. That review scrutinizes period-appropriate detailing: trim profiles, porch details, window proportions. Skipping the permit risks a stop-work order and a retrofit correction that costs more than doing it right the first time. We pull permits on every job, and we manage the review process so you don’t have to.
A kitchen remodel in Claremont runs $14,000 – $45,000, a bathroom remodel $9,000 – $28,000, and a garage conversion $30,000 – $80,000. A full home addition lands between $45,000 and $130,000, while an ADU runs $90,000 – $220,000. What moves your number within those ranges is what we find during discovery, so call (877) 752-3154 and we’ll walk you through a realistic budget for your specific home.
We stop and size it properly with an engineer before we proceed. On a 1910s Craftsman near the Claremont Village, our crew opened a wall for a kitchen addition and found knob-and-tube wiring spliced into newer runs plus undersized framing under a load-bearing header. We wrote the electrical rough-in and framing repair into a signed change order with an inspection sign-off before closing anything back up, and the homeowner knew the number before we touched it.
You can’t eliminate surprises in a 60-to-70-year-old home, but you can price them before they happen. On Claremont’s south-side ranch tracts, we regularly find plaster walls over failing subfloor and shower pans that never got a proper waterproofing membrane. We write allowances for exactly these failure modes into every ranch-era contract, so when we find them, the number’s already on the table. Call (877) 752-3154 for a free estimate.
