Fast, Reliable General Contractor Across Claremont
Finding a General Contractor who understands Claremont’s older homes is the difference between a remodel that stays on schedule and one that stalls for months. We work throughout the 91711 zip code, from Craftsman bungalows near the Village to mid-century post-and-beam homes south of Foothill Boulevard. Most Claremont homeowners who call us are trying to solve the same problem: they want one accountable team for the whole job, not four vendors pointing fingers at each other. Call (866) 472-1908 and we’ll talk through what your project actually involves, including the parts other contractors gloss over until the walls are open.
Why San Bruno Construction Is Claremont’s Preferred General Contractor Company
Homeowners in Claremont hire us because we don’t treat a remodel like a paint job. When a home near the colleges has original 1920s framing or a south Claremont tract house has post-and-beam construction from the 1960s, the work requires someone who has seen what’s behind those walls before. Our team has walked enough Claremont job sites to know that a kitchen wall in the Village may hide cloth-wrapped wiring, while an exterior wall on a mid-century modern may have clear-heart redwood siding that the historic review board will not let you swap for fiber cement. That local knowledge changes how we price, how we schedule, and how we communicate.
Noel Carvalho leads every Claremont project with a simple rule: no surprise change order, ever. If we open a wall and find something the original scope didn’t cover, we stop, document it, price the fix in writing, and get your approval before we touch it. Claremont customers consistently tell us the same thing: they chose us because we answered the phone, showed up when we said we would, and explained the permit process in plain English.
Styles & brands we work with







Licensed General Contractor in Claremont
A Licensed General Contractor in Claremont runs the entire job, from first permit submittal to final inspection. On a typical Claremont remodel, that means scheduling the demo crew, coordinating the plumber and electrician, ordering cabinetry and countertops ahead of lead times, managing the framing and drywall, and making sure the inspection sign-off happens before any wall closes. We act as the single point of accountability, which matters more in Claremont than in most cities because the local review process adds a layer most contractors don’t plan for. Kitchen remodels in Claremont run $14,000 – $45,000. Bathroom remodels run $9,000 – $28,000. A home addition runs $45,000 – $130,000, and an ADU runs $90,000 – $220,000. A garage conversion runs $30,000 – $80,000.
Historic Review and Permit Coordination
If your Claremont home sits in the Village or near the colleges, your plans may need to go through historic preservation review before the building department will accept the permit application. We prepare the drawings with the materials the review board expects, whether that’s matching clear-heart redwood siding, preserving original rooflines, or keeping window proportions intact. We handle the submittal, the revision cycles, and the follow-up so you’re not sitting on a stalled project for months.
Written Change Orders, Priced Before Work Begins
Any general contractor who quotes an open-up remodel in Claremont without allowances for what’s behind the walls is guessing. We write allowances into the contract for framing corrections, outdated wiring, and dry rot, then price every change order in writing before we proceed. You approve the number first. That’s the entire point.
Residential General Contractor in Claremont
A Residential General Contractor in Claremont manages the trades, the materials, and the schedule for work on your home, whether it’s a kitchen remodel, a full roof replacement, or a prefab ADU install. Because Claremont’s housing stock is unusually diverse, from 1920s Spanish Colonial Revival near the colleges to 1950s Eichler-style post-and-beam tract homes on the south and east sides, the job looks different on every street. A home addition on a pre-war bungalow means matching foundation lines and rooflines under design review. A roof replacement on a foothill-edge home means accounting for Santa Ana wind uplift and wildfire-related detailing. We coordinate all of it under one contract.
Post-and-Beam Open-Up Work
Mid-century post-and-beam homes in Claremont are beautiful, and they’re also deceptive. The beams carry the load, but the infill framing between posts was often built to an older standard, and the wiring in those walls is frequently original. When we open a wall for a kitchen or bathroom remodel, we inspect the framing and rough-in before we close anything. If we find undersized framing or cloth-wrapped wire, we price the correction as a written change order and get inspection sign-off before the drywall goes back on.
Prefab ADU and Addition Coordination
We offer ADU and prefab construction through brands like Dvele, Mighty Buildings, Boxabl, and Plant Prefab, a scope most residential remodelers in Claremont cannot touch. If you want a backyard ADU on a Village-adjacent lot, the design review process still applies, and we handle that coordination from factory drawings to final inspection. A prefab structure still needs a foundation, utility connections, and a general contractor who knows Claremont’s permit path. That’s us.
Trusted Brands We Service in Claremont
We’re not tied to one cabinet line or one countertop supplier. Claremont customers choose from brands like KraftMaid and Wellborn for cabinetry, Cambria, Silestone, and Caesarstone for countertops, and Kohler, Grohe, and Toto for plumbing fixtures. On the exterior, we source GAF, CertainTeed, and Owens Corning roofing; James Hardie siding; Therma-Tru doors; and Belgard pavers. For ADUs and prefab builds, we work with Dvele, Mighty Buildings, Boxabl, and Plant Prefab. That access to 50+ established brands means budget decisions are never forced on you. You pick what fits your home and your budget, and we install it.

AfterCommon General Contractor Problems We See in Claremont Homes
- Cloth-wrapped wiring behind post-and-beam walls. Homes built in the 1950s and 60s across south Claremont often still have original cloth-insulated wiring. Once the wall is open and the inspector sees it, the electrical rough-in must come up to current code before we can close.
- Undersized or damaged framing under exposed beam lines. Post-and-beam construction carries the roof load differently than standard stud framing. When infill framing has been notched, water-damaged, or built undersized, the framing correction has to happen before insulation and drywall.
- Historic review stalls on Village-area homes. If a contractor pulls a permit without clearing Claremont’s historic-preservation review first, the entire scope stops. We sequence the review before the permit so the work doesn’t sit dead for months.
- Failed waterproofing at the foothill edge. Claremont’s intense inland sun and occasional Santa Ana wind events put real stress on roof edges, flashing, and exterior penetrations. We inspect waterproofing details during any exterior or roof-related work, because a leak found after the fact costs more than one caught during construction.
Pricing for General Contractor in Claremont, CA
Here’s what Claremont homeowners can expect to pay for major residential work, based on the scope we typically see in this market:
| Project Type | Typical Claremont 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 |
| Garage Conversion | $30,000 – $80,000 |
The biggest variable in Claremont is what’s behind the walls. An open-up remodel on a post-and-beam home that needs framing corrections and electrical updates will land at the higher end of these ranges. A project with clean rough-in and no historic review will land lower. We give you a written, line-item estimate before you sign anything, and we write allowances into the contract so you know what the surprises will cost before they happen. Call (866) 472-1908 to schedule a free estimate.

FAQs About General Contractor in Claremont
We stop work, document what we found, price the fix as a written change order, and get your approval before we proceed. In Claremont, this usually means cloth-wrapped wiring or undersized framing behind post-and-beam walls, both of which need to come up to current code before an inspector will sign off and the wall can close. The cost gets added to the contract as an approved change order, never as a surprise. Call (866) 472-1908 if you want a contractor who prices surprises before they happen.
Yes. Homes in the Village and near the colleges often fall under the Claremont Historic District or historic preservation review, which means materials and rooflines must match the original character before the building department will issue a permit. We prepare the drawings with that review in mind, including clear-heart redwood siding matches and window proportion details, so the submittal moves on the first or second cycle. Call (866) 472-1908 to talk through your specific property.
We schedule inspection sign-off before any wall closes, every time. On a Claremont remodel, the critical inspections are the framing inspection and the rough-in inspection for electrical, plumbing, and mechanical. If we close a wall without sign-off, the inspector can require us to tear it back open, which costs time and money. Our sequencing puts inspections on the calendar before the drywall crew shows up. Call (866) 472-1908 for a contractor who treats inspections as a milestone, not an afterthought.
Because the walls hide old wiring and undersized framing, and the review process can add scope before work starts. A 1960s post-and-beam home south of Foothill often has cloth-wrapped electrical and infill framing that was built to an older standard. Fixing those issues is necessary work, but it’s work a generic quote won’t include. We write allowances for it into the contract from day one. Call (866) 472-1908 for a quote that accounts for what Claremont homes actually contain.
Yes. Every Claremont project runs on a written draw schedule tied to completed milestones, not calendar dates, and we close with a punch list walkthrough before final payment. That means you pay as the work is verified complete, and the last check doesn’t clear until the punch list is done. Call (866) 472-1908 and ask us to walk you through a sample contract.
