We know Claremont’s housing stock because we work in it every week. These aren’t tract homes built to a spec sheet. They’re 1920s bungalows in the Village, mid-century ranches near Memorial Park, and Spanish Colonials tucked under mature oak canopies. Each one has its own history, its own quirks, and its own set of problems waiting behind the drywall. Brent Calloway and our whole team approach every Claremont job with that understanding. You’re not getting a generic remodel crew. You’re getting a contractor who knows what a 100-year-old foundation looks like in this city, and what it costs to fix it right.
Why Square One Builders Is Claremont’s Preferred Home Remodeling Company
Brent Calloway founded Square One Builders on a simple idea: one contractor should be accountable for the whole job. Not three subs pointing fingers at each other. Not a general contractor who disappears after demo. One team, one contract, every system from the roof down to the pavers. That’s why Claremont homeowners keep calling us back when they’re ready for the next phase.
Our Home Remodeling team has managed full-scope projects throughout Claremont, from kitchen remodels off Foothill Boulevard to whole-house renovations in the neighborhoods around the Claremont Colleges. We’ve learned what this city’s older homes hide, and we’ve built our process around catching it early. Homeowners working with us get honest line-item allowances for the unknown, written change orders for anything we find, and approval before a single unexpected repair starts. That’s the difference between a quote that holds and one that balloons.
When you call us about a remodel anywhere in Claremont, you’re not getting a sales rep reading from a script. You’re getting a general contractor who knows the city’s design review process, understands the tree protection ordinances near the foothills, and has pulled permits here long enough to know which ones slow a job down and which ones don’t. We’ve done the work. We know what it takes.

Whole House Remodel in Claremont
A whole house remodel in Claremont runs $45,000 – $130,000, and it’s the right move when a home’s layout no longer fits how you live and the systems behind the walls need updating anyway. In Claremont, this usually means opening up a 1920s Craftsman or a post-WWII ranch and dealing with what’s inside: outdated wiring, plumbing that’s past its useful life, framing that was never sized for modern loads, and waterproofing that failed years ago. We scope the project from the ground up, write the allowances for known unknowns, and price the finish work off real material selections, not guesses.
Structural and Systems Scope
Most whole house remodels in Claremont include some level of structural work. We handle foundation retrofits, beam replacements, wall removals, and full re-wiring and re-plumbing as part of the same contract. No separate electrician to call. No framing sub who answers to someone else. It’s all Square One, and it’s all coordinated so inspections don’t stall the job.
Finishes and Material Selection
Once the walls are open and the systems are updated, we move into finishes. Our Claremont clients typically choose cabinetry by KraftMaid or Wellborn, countertops by Cambria or Silestone, and plumbing fixtures by Kohler, Moen, or Grohe depending on budget. We spec the right material for your project, whether that’s James Hardie siding on the exterior or a full kitchen with quartz counters and soft-close drawers on the interior. You’re getting brand options at multiple price tiers without switching contractors.
Luxury Home Remodeling in Claremont
Luxury home remodeling in Claremont is a different animal from a mid-range refresh. These projects, often in the historic district homes around the Claremont Colleges or the larger foothill properties, demand higher-end materials, more detailed millwork, and a contractor who can coordinate custom cabinetry, premium stone, and specialty windows without dropping the ball. Budgets for these projects typically start around $45,000 for a single high-end space and climb from there; a full luxury renovation can exceed $130,000 depending on material decisions.
High-End Kitchens and Primary Suites
We’ve built luxury kitchens in Claremont with KraftMaid custom cabinets, Cambria quartz, and statement islands with waterfall edges. These jobs require precise templating, careful sequencing with the stone fabricator, and a GC who can keep plumbing, electrical, and cabinetry moving in the right order. That coordination is where Square One earns its keep on high-end work.
Historic District Sensitivity
Luxury work in Claremont’s historic core often intersects with the city’s design review process. You may need approvals for exterior changes, window replacement, or additions that alter the street-facing character of the home. We’ve worked through those reviews and know how to prep a submittal that moves. More important, we know how to design a luxury remodel that respects the original architecture while giving you modern systems and finishes. A 1928 Spanish Colonial can have a modern kitchen and a master bath with a walk-in shower. It just has to be done thoughtfully.
Trusted Brands We Service in Claremont
Square One Builders works with 50+ material brands across every major home system, and we stock or can quickly source parts for Claremont jobs from manufacturers including CertainTeed and Owens Corning for roofing, plus Atlas for steep-slope and specialty applications. Whether you’re replacing a roof as part of a whole-house remodel or re-siding an addition off Indian Hill Boulevard, we’ve got the brand access to match your budget and the install experience to get it done properly. No settling for whatever the supply house has in stock that week. We plan material selections with you in advance and order what the job actually needs.

AfterCommon Home Remodeling Problems We See in Claremont Homes
- Knob-and-tube wiring in 1920s Craftsman homes. We routinely find live knob-and-tube behind walls that were never opened. Once exposed, Claremont code requires it to be decommissioned and replaced, and that’s a line item you want written into your contract as an allowance, not a surprise change order.
- Failed waterproofing in mid-century bathrooms. Many post-WWII homes in Claremont were built with tile set directly on drywall or mud beds with no waterproofing membrane behind them. By the time we open the wall, the shower pan has usually been leaking for years and the subfloor needs replacement.
- Undersized framing in older additions. We’ve seen Claremont additions built decades ago with 2×4 rafters spanning distances they were never rated for. When we open the ceiling for a remodel, the fix often means sistering joists or adding a beam, and that changes the scope in writing before we proceed.
- Heritage tree complications on foothill lots. Homes below the San Gabriels often have Coast Live Oaks that Claremont protects. A remodel that grades near one can trigger an arborist report and a tree protection plan before the city issues permits. We’ve learned to flag this on day one, not at permit time.
Pricing for Home Remodeling in Claremont, CA
Here are the market ranges we see for common scopes in Claremont, based on current material and labor costs across 91711. These are honest numbers, not lowball teasers. Where a range is wide, it’s because the existing conditions drive it. A kitchen in a 1920s bungalow with knob-and-tube wiring will land higher than the same kitchen in a 1990s house with modern electrical.

|---|---|
| Kitchen Remodel | $14,000 – $45,000 |
| Bathroom Remodel | $9,000 – $28,000 |
| Home Addition | $45,000 – $130,000 |
| Cabinet Installation | $4,000 – $13,000 |
| Countertop Installation | $2,000 – $6,500 |
What moves the number in Claremont specifically: the age of the wiring, the condition of the subfloor once the old tile comes up, whether a heritage oak sits inside the work zone, and whether you’re in the historic district with design review requirements. We write allowances for these known unknowns into the contract up front. Then we price any surprises in writing and get your signature before we touch the work. Call (877) 688-9930 to schedule a free estimate.

FAQs About Home Remodeling in Claremont
Because homes built in the 1920s through the 1960s often hide outdated wiring, failed waterproofing, or undersized framing that only becomes visible once demolition starts. In Claremont specifically, knob-and-tube wiring is common in the Craftsman bungalows around the Village, and it must be replaced when exposed. A contractor who quotes off surface finishes gives you a number that can’t survive demo. We build allowances into the contract for these known unknowns, then write change orders with exact labor and material costs for anything found before we proceed. Call (877) 688-9930 for a quote that accounts for what your Claremont home actually has inside it.
Yes, frequently. Claremont protects Coast Live Oaks and other heritage trees, and any remodel that involves grading, trenching, or construction inside the tree’s protected zone can trigger an arborist report and a city tree protection plan before permits are issued. This is not a standard step in most Southern California cities, but it’s routine here. We’ve pulled these permits on foothill lots and near the Colleges, and we flag the requirement at the first site walk, not at the permit counter.
Once walls come open, Claremont code requires permits for any electrical, plumbing, structural, or mechanical work that gets exposed or altered. That typically includes re-wiring to replace knob-and-tube, re-piping supply and drain lines, structural repairs to framing or foundation, and waterproofing changes in wet areas. We pull all permits, schedule inspections, and keep the job moving so inspections don’t stack up and stall the schedule. You get one accountable contractor for the whole permit process.
We write the budget around line-item allowances and fixed brand selections before we start. For a high-end kitchen in a historic Claremont home, that means selecting KraftMaid cabinetry and Cambria or Silestone countertops at specific price points, not open-ended categories. Then we put the structural and system unknowns into allowances with defined ranges. When we open a wall and find something, the change order shows you the exact labor and material cost before we spend a dollar. No drift, no vague “unforeseen conditions” charges. Call (877) 688-9930 for a budget that’s built to hold.
Yes, and that’s the smart way to do it. A small Claremont kitchen typically runs $9,000 – $20,000, and a small bathroom $5,000 – $12,000. Joint pricing can reduce mobilization and overhead because the crew is already on site, and we’re coordinating cabinet, countertop, and plumbing fixtures across both spaces under the same contract. We’ll give you separate line items for each space so you know exactly what you’re spending on the kitchen versus the bath.
