Fast, Reliable General Contractor Across Claremont
When you need a general contractor in Claremont, you’re hiring someone to manage the people, the permit paperwork, and the surprise problems that come with opening up an older home. That’s the job. Around here, those surprises are predictable: buildings from the 1920s and 1930s with original wiring, plaster over wood lath, and the city’s design-review and tree-protection rules layered on top. You want a written price before a single wall gets touched, and a contractor who replies when the inspector flags something. That’s what we do.
We’re Penhallow Remodeling Riverside, and our crews work throughout Claremont on kitchen, bath, and whole-home remodels. Trevor Nash runs the work with one rule: every job gets a written scope, a real price, and a 365-day promise to make it right. Call (341) 895-1170 to talk through what you’re planning.
Key Takeaways
- Written price before work starts, on every project. The number you sign is the number you pay, unless a change order is signed by both of us.
- We know Claremont’s permitting and design-review process, and we don’t start exterior work until approvals are in hand.
- Every project carries the 365-Day Done Right Promise, in writing.
- A live person answers the phone 24/7. No answering service, no callback window.
Why Penhallow Remodeling Riverside Is Claremont’s Preferred General Contractor Company
Homeowners in Claremont call us after they’ve been burned once. Maybe a bid came in low, then ballooned after demo. Maybe a crew ghosted for three weeks. That pattern is exactly what we’re built to avoid. The Kingswell standard, in place since 2004 for every independent location in the family, says the price gets put in writing before work starts, the crew arrives in a defined window, and the job site is left clean. We’re held to it by our own guarantee, and we hold the subs to it too.
Our background-checked, uniformed technicians show up on time and in one piece. Materials come from trade brands whose warranties support ours: KraftMaid and Wellborn cabinetry, Cambria, Silestone, and Caesarstone countertops, Kohler and Moen fixtures. When a homeowner off Base Line Road asks what’s behind the tile, we explain “cement board substrate” in plain words and then show them the brand name. It’s the same way we’d talk across a kitchen table, because that’s often where the conversation starts.
Scheduling and dispatch run from our Los Angeles office, but the crews serving Claremont work locally and know the area’s housing stock. We don’t waste the first day getting oriented.
Styles & brands we work with
Licensed General Contractor in Claremont
A licensed general contractor in Claremont is the one who holds the state license, pulls the permits, coordinates the electrician, plumber, and framer, and is accountable to the city when an inspection gets scheduled. That accountability matters more in Claremont than in most cities. If you start exterior work without design-review approval, the city can issue a stop-work order. A licensed contractor knows that and sequences the work so it doesn’t happen. That’s not a formality; it’s the main reason a remodel here can stall for weeks when someone skips the process.
Costs line up with the same rule as anywhere: what you open up and what the city requires. Kitchen Remodeling in Claremont typically runs $14,000 to $45,000. A bathroom lands between $9,000 and $28,000. A home addition is $45,000 to $130,000 depending on foundation, roofline, and how much tree protection is involved. The written quote lays out what’s in that number, including allowances for the unknowns most older Claremont homes hide.
Written scope, no door-price drift
We write the price before work starts, and the contract includes specified allowances for unknowns: wiring replacement, framing repair, rotted subfloor. If we open a wall and find something the allowance doesn’t cover, we stop and get your sign-off on a written change order before touching it. That’s the only way the number on day one survives demo day.
Permits pulled, inspections passed
We pull permits for every remodel in Claremont. Not optional. A kitchen or bath that moves plumbing or electrical requires one, and unpermitted work is a problem when you sell. The inspector sees our work before the walls close, and the sign-off goes in the file. It’s slower. It’s also the only way we’ll do it.
Residential General Contractor in Claremont
A residential general contractor in Claremont pays attention to things a commercial contractor doesn’t: mature oaks close to the foundation line, 100-year-old plaster over wood lath, and homeowners who live in the house while we’re working in it. Most of our projects here are older homes, and the planning phase is where the job is actually won. We walk the site, check the tree inventory against the lot plans, and pull the permit history before we write the bid.
That changes the work. Claremont’s tree preservation ordinance means a protected oak can sit exactly where a driveway or addition would go, and you can’t just pave over the root zone. We design around the tree, adjust foundation placement, and sometimes trim the roofline to keep branches off. A contractor who ignores that ends up with a cracked slab or a denied permit. We don’t.
Older homes, honest scoping
On a 1920s Craftsman near the Village, our crew opened a wall for a kitchen remodel and found original knob-and-tube wiring still live behind the plaster. We stopped work, brought in the city inspector, and rewrote the scope with a written change order before pulling new circuits. The permit’s final sign-off confirmed the old wiring was properly abandoned before the walls closed. That’s how surprise discoveries should go: documented, approved, and finished, not tacked onto the final bill without a conversation.
Additions and ADUs under design review
Room additions and accessory dwelling units in Claremont face the city’s design and landscaping review more strictly than in neighboring cities. The “City of Trees and PhDs” ethos is real, and the preservation culture shows up in the review comments. Roof pitch, window proportion, even exterior paint color can get flagged. We’ve done enough of these to anticipate the comments, and we build the review timeline into the schedule so you’re not left wondering why nothing moved for a month.
Trusted Brands We Service in Claremont
For fence and hardscape components that often ride along with a larger remodel, we source from General Contractor-grade trade brands like Belgard, Bufftech, and Jerith. We don’t stock every SKU, but we keep common Claremont-spec parts available through our local suppliers, which means a Belgian block paver or a matching gate insert doesn’t add a week to the schedule. When the plan calls for a specific product, we verify inventory before we commit to a start date, and the brand name goes into the written quote. No substitutions unless you approve them.

AfterCommon General Contractor Problems We See in Claremont Homes
- Knob-and-tube wiring behind intact plaster. Homes from the 1920s and 1930s often still have original cloth-insulated wiring in the walls. It’s not inherently failing, but once the wall is open for new cabinets or a reconfigured bath, the city will want it addressed. We plan for this with a wiring allowance in the contract.
- Undersized or sagging roof framing. Claremont’s hot, dry summers and intermittent Santa Ana winds cause framing to dry and move. A ceiling that looks flat can hide a ridge beam that has settled. We check the framing before we sign off on the finish work.
- Failed waterproofing in showers and tub surrounds. Older Claremont homes often have tile set directly over drywall or a thin mortar bed with no modern membrane. When we open a shower wall, the substrate is usually compromised. We replace it with a proper cement board and waterproofing system before any tile goes up.
- Mature tree root zones crossing the foundation line. Protected oaks and other mature trees frequently sit close to older homes, and their roots can destabilize slabs and walkways. Claremont’s tree ordinance means you can’t just cut the roots or remove the tree. We work with the city arborist’s guidance to protect both the tree and the structure.

FAQs About General Contractor in Claremont
Claremont protects mature oaks and other significant trees, which means any foundation, driveway, or roofline near a protected tree has to be designed around the root zone and canopy. If the tree sits near your proposed addition or new patio, expect the city to require an arborist report and possibly a revised site plan. We handle that process early, because digging before approval is a stop-work risk and can damage a tree that can’t be replaced. Call (341) 895-1170 and we’ll check your lot against the tree inventory before you commit to a design.
Live knob-and-tube wiring, rotted sill plates, termite damage, and thin or non-existent waterproofing behind old tile are the usual finds. We expect them, which is why the contract includes allowances for these specific categories. When we find something outside the allowance, we stop, document it, and get a written change order signed before continuing. You’re never told about a problem after the invoice arrives.
Yes, if the work moves plumbing, electrical, or load-bearing walls, and in Claremont that covers nearly every kitchen and bath remodel we do. The city will inspect the work before the walls are closed, and the permit record stays with the house. We pull the permit, we schedule the inspections, and we don’t close a wall until the sign-off is in hand. It protects you when you sell, and it protects us from building something that fails later.
We document it, bring in the appropriate inspector or specialist, and write a change order that shows exactly what it costs and why. You approve it in writing before that part of the work proceeds. Our 365-Day Done Right Promise covers the finished work for a full year after completion, and if a repair fails, the follow-up visit is free. No argument about who pays for the return trip.
Because older Claremont homes regularly hide outdated wiring, undersized framing, and failed waterproofing that no amount of pre-bid inspection can fully see. Contractors who write a low fixed bid without allowances will come back to you for more money when the surprises appear. We structure the quote differently: the written price includes line-item allowances for the known unknowns, and anything beyond them is raised before the work happens, in writing, with your signature. The price can still move, but it never moves by surprise. Call (341) 895-1170 for a free estimate and a written quote.
