Fast, Reliable General Contractor Across Claremont
A general contractor in Claremont manages the entire scope of a remodel, addition, or ADU project so you are not juggling an electrician, plumber, framer, and roofer on your own. In Claremont specifically, that coordination has to run through the city’s architectural review process before work starts on front-facing additions and ADUs near the Village and the Claremont Colleges. We know those steps cold because we work in 91711 regularly. Call (833) 382-8544 to schedule a free estimate and get a written line-item scope before you commit to anything.
Claremont is not Pomona. It is not Montclair. The review culture here is different, the housing stock is older, and what hides behind a 1920s lath-and-plaster wall is different from what a 2005 tract home hides. That local knowledge changes how we quote, how we schedule, and how we protect your budget when the walls come open.
Why Gold Star Contractors Is Claremont’s Preferred General Contractor Company
Homeowners in Claremont call us because we show up with a plan for the city’s design-review process, not a blank look. Streets north of Foothill Boulevard and around the Village have some of the oldest housing stock in the eastern San Gabriel Valley. A remodel on Indian Hill Boulevard does not get quoted the same way as a remodel in North Pomona. Our team has walked enough Claremont interiors to know where knob-and-tube wiring tends to hide, where undersized headers show up, and where failed waterproofing sits behind 1950s ranch home kitchens.
We are a full-scope general contractor led by Noel Carranza, and we carry the brand access that matters on higher-end Claremont remodels: Toto and American Standard fixtures, Schluter waterproofing systems, and Sterling bath products. That means we can specify premium materials and install them to manufacturer standards under one accountable team. Your home is too important to coordinate five different contractors.
Our work in Claremont has been focused on the Village area, the Claremont Colleges neighborhoods, and the 1950s and 60s ranch belt that runs toward the 210. We know what county inspectors in this corridor want to see, and we know what the city’s design reviewers ask about on front-facing additions. That is the difference. One contractor. Every system. No handoff gaps.
Styles & brands we work with







Residential General Contractor in Claremont
Residential General Contractor work in Claremont covers the project from pre-construction planning through final inspection, and in this city it has to account for something most neighboring towns do not require: architectural review on anything visible from the street. A kitchen remodel usually runs $14,000 – $45,000 in Claremont. A bathroom remodel typically lands between $9,000 – $28,000. Those are real market numbers for 91711, not national averages. When you open a wall in a 1920s Craftsman bungalow near the Village, you may find something that changes the number. We handle that with written change orders, not verbal surprises.
Remodel and Renovation Scope
Kitchens. Bathrooms. Whole-home interior renovations. Detached garage conversions. Room additions. Each one starts with a site walk, then a written scope of work, then a fixed price with allowances for the unknowns that Claremont homes hide. We do not give a handshake number and hope. We give a line-item bid and update it in writing when demo reveals something the original drawings did not show.
Claremont’s older homes, especially the Spanish-Revival bungalows and early-1900s Craftsman houses near the Village, often have original rough-in that predates current code. Opening a wall on a job like that is not the same as opening a wall in a 1990s tract home. We budget for it and we tell you before we swing a hammer.
Additions and ADUs Under Claremont Review
A front-facing addition in Claremont is not a routine permit. The city’s architectural review and historic-preservation culture around the Colleges and Village means plans can get sent back for revisions on window proportions, rooflines, and materials before a single footing gets poured. That is a step contractors in Pomona or Montclair do not face the same way. We have done it. We know how long it takes and we build that timeline into the schedule.
Hire a General Contractor in Claremont
When you Hire a General Contractor in Claremont, you are hiring someone to own the permit, the trade coordination, the material procurement, and the inspection sign-offs. A home addition in Claremont runs $45,000 – $130,000. An ADU typically costs $90,000 – $220,000 depending on whether you go site-built or prefab. A garage conversion, which Claremont’s detached-garage housing stock makes especially common, usually lands between $30,000 – $80,000. Those are the numbers we write into our Claremont bids.
Single-Source Accountability
Gold Star Contractors is a single-source general contractor. You are not calling a framer on Monday, a plumber on Wednesday, and a tile setter on Friday. We specify the brand, manage the install, and stand behind the result. From the roofline to the countertop, and the ADU out back. For a Claremont homeowner dealing with design review on one side and an aging house on the other, that accountability is the reason to hire a full-scope GC instead of a trade-by-trade approach.
Noel Carranza runs the project team directly. You get one name to call, one schedule to track, one contract to hold us to. We work with 50+ manufacturer brands across cabinetry, countertops, roofing, windows, doors, fencing, hardscaping, plumbing fixtures, and prefab structures, so your material selections are not limited to whatever the local showroom happens to stock.
Written Change Orders Before Work Proceeds
Claremont homes hide things. That is not a scare tactic, it is a fact of working on housing stock that runs from 1900s Craftsman to 1960s ranch. When our crew finds something behind a wall, we stop, document it, price it, and get your written approval before we proceed. No mystery line items. No drywall going up over an unapproved change. That process is written into our contract, not improvised when a problem appears.
Trusted Brands We Service in Claremont
We install and service premium plumbing and tile systems from American Standard, Toto, Schluter, and Sterling on Claremont remodel projects. These are not entry-level fixtures you grab off a shelf. Toto toilets and American Standard tubs come with specific rough-in requirements. Schluter waterproofing systems have manufacturer-mandated installation standards. We know those specs. For Claremont homeowners, that means a kitchen or bath remodel does not stall because the installer did not understand the product. Premium materials, professionally installed. We keep common replacement parts and rough-in components available so a vanity swap or shower replacement in 91711 does not wait on a backorder.

AfterCommon General Contractor Problems We See in Claremont Homes
- Knob-and-tube wiring hidden inside original walls. It is still live in some Village-area homes, and it is often spliced into newer circuits. A remodel that opens a wall will force it to be addressed, and a permit will not close until the electrical rough-in is corrected.
- Undersized framing that does not match the drawings. We have opened load-bearing walls on 1920s Spanish-Revival bungalows and found headers that were never sized for the span. The city’s inspectors catch it. We catch it first and price the fix before drywall goes up.
- Failed waterproofing behind old showers and window sills. Claremont sits at the base of the San Gabriels with intense summer sun and Santa Ana wind events. Stucco and flashing failures after years of heat and wind exposure are common. A shower tear-out often turns into a subfloor and framing repair once the tile comes off.
- Detached garages with deferred maintenance. Many Claremont homes have detached garages with original slabs, old roofs, and electrical that will not support current code. A garage conversion to an ADU almost always needs structural and electrical upgrades before finish work begins.

FAQs About General Contractor in Claremont
Because Claremont’s older housing stock, especially the 1900s to 1960s homes near the Village and Colleges, frequently hides knob-and-tube wiring, undersized framing, or failed waterproofing that no pre-demo inspection can see. We write allowances into the contract and issue written change orders with documented pricing before any new work proceeds. Call (833) 382-8544 for a quote that explains those risks up front.
Yes. Front-facing additions and ADUs in Claremont must clear the city’s architectural review and historic-preservation process before a building permit is issued, especially near the Village and the Claremont Colleges. That means your plans, rooflines, and exterior materials need approval before we pull the permit. We handle that review as part of our scope.
We lock the scope, write allowances for the unknowns that Claremont homes hide, and issue a written change order with pricing and your signed approval before any extra work starts. No surprise line items at the end. No drywall covered before you have approved the number. That process is why homeowners in 91711 trust us with five-figure remodels.
A permit means the county inspector walks the electrical rough-in, the framing, the waterproofing, and the final build. It forces corrections that protect you and your resale value. In Claremont, a permit also means your front-facing addition or ADU cleared design review. We pull permits on every job and we do not start work until they are issued.
Yes. Claremont’s older homes often have detached garages that convert well into accessory dwelling units, but the original slab, roof structure, and electrical service usually need upgrades to meet current code.
