Remodeling Company in Claremont, CA
Home renovation in Claremont usually means working on a house built between 1920 and 1970, often in a historic district, sometimes under a protected oak canopy. That changes how a remodel gets planned, permitted, and priced. Square One Builders has served Claremont since 2014 as a full-scope general contractor, which means we handle the structural work, the finishes, and the coordination with the city’s design review process under one contract. Call (877) 688-9930 to talk through your project.
Why Claremont Homes Are Different
Claremont sits at the base of the San Gabriel Mountains, and the housing stock reflects a century of building styles you will not find in newer Pomona Valley tracts. Craftsman bungalows from the 1920s, Spanish Colonial Revival homes near the Village, and post-war ranch houses in the flats north of Foothill Boulevard all carry their own construction quirks. We regularly open walls in Claremont and find balloon framing, knob-and-tube remnants, or foundation conditions that a newer home simply would not have. Add in the mature Coast Live Oaks throughout neighborhoods like Claraboya and the area around Memorial Park, and a simple addition can trigger arborist reports, tree protection plans, and design review conditions before a shovel touches dirt.
The climate matters too. Hot, dry summers with Santa Ana wind events mean exterior materials and roofing underlayments need to be selected for heat and ember exposure, especially on the foothill side of town. Winter storms, while infrequent, can drop enough rain in a short window to expose drainage and erosion problems on sloped lots. None of this is unmanageable. It just means the planning phase in Claremont carries more weight than it does in a 2005 tract development in Eastvale.
Styles & brands we work with
Our Main Claremont Services
Most Claremont homeowners reach out to us for one of two reasons: they need a general contractor to manage a whole-home or multi-system project, or they are focused on a specific remodel and want one team accountable for the entire scope.
General Contractor in Claremont
When a Claremont project touches more than one trade, the general contractor question stops being a formality and becomes the whole job. A second-story addition on a 1940s home in the Village might involve foundation retrofit, framing, electrical service, roofing, and windows, all while coordinating with the city’s design review board. Trying to sequence five separate contractors through that process is where Claremont remodels stall or go sideways. We run the entire project under one contract, one schedule, and one point of accountability. That is the entire point. Read more about how we operate as a General Contractor in Claremont.
Home Remodeling in Claremont
A kitchen remodel in a 1924 Craftsman is not the same job as a kitchen remodel in a 1998 stucco box. The footprint is often tighter, the walls are rarely square, and the existing plumbing and electrical might date back decades. Homeowners in Claremont typically want the modern function without erasing the character, which is a planning and material-selection challenge, not just a demolition decision. We source cabinetry, countertops, plumbing fixtures, and windows that fit both the house and the budget. See how we approach full-scope Home Remodeling in Claremont.

Home Renovation in Claremont
Home renovation in Claremont runs a wider range than people expect because the city’s older housing stock hides real variability behind the walls. A kitchen remodel in a 1960s ranch near the Claremont Colleges might start at $14,000 and stay clean, while the same footprint in a 1925 Spanish Colonial with foundation settling and outdated electrical can push toward $45,000 once structural and systems work are included. We have been managing that variability since 2014, and the value of a Home Renovation contractor who has seen hundreds of these homes is that the surprises get found during planning, not during demolition.
Home Renovation Contractors
Signs you need it
Multiple trades are involved, the home predates current building codes, or you want one accountable team rather than coordinating electricians, plumbers, and carpenters yourself.
What it costs in Claremont
A full home renovation in Claremont typically ranges from $45,000 to $130,000 depending on square footage, systems age, and finish level.
How we do it
We start with a site assessment and existing-conditions review, scope the full renovation with written line-item pricing, then manage demolition, rough-in, finish work, inspections, and closeout under one contract.
Renovation Contractors
Signs you need it
You have a defined scope across several rooms or systems, and you want a contractor who will spec the right material for each surface rather than defaulting to builder-grade.
What it costs in Claremont
Renovation projects in Claremont that span multiple rooms generally fall between $14,000 and $45,000 when focused on kitchens, or $9,000 to $28,000 for bathrooms.
How we do it
We define the scope room by room, order materials from our brand portfolio, and run the renovation with one crew schedule so drywall, paint, tile, and fixtures land in sequence.
Home Improvement Contractors
Signs you need it
You are making targeted upgrades, not gutting the house, and you want them done to a standard that matches the rest of the home.
What it costs in Claremont
Cabinet installation runs $4,000 to $13,000, countertop installation $2,000 to $6,500, and bathroom vanity installation $800 to $3,000 in Claremont.

Home Renovation Companies
Signs you need it
You want a company with real depth across roofing, cabinetry, plumbing fixtures, siding, and hardscaping, not a kitchen-only shop trying to subcontract the rest.
What it costs in Claremont

Will a Claremont renovation require design review?
Many Claremont homes fall within historic or conservation districts, which means exterior changes and some interior structural work need design review board approval before permits are issued. We handle that paperwork and attend hearings as part of the project. Call (877) 688-9930 to discuss your property.
How long does a full home renovation take in Claremont?
Most full renovations in Claremont run three to six months once permits are issued, with design review, arborist reports, and material lead times adding weeks on the front end. We sequence the work so you are never waiting on a trade. Call (877) 688-9930 for a realistic timeline on your project.

We install and service prefabricated and panelized structures from Abodu, Dvele, and Mighty Buildings, which matters for Claremont homeowners weighing an ADU against a traditional ground-up addition.

Claremont pricing pushes upward when a project touches historic review, protected tree mitigation, or older home systems like original plumbing and electrical. The biggest single variable is usually what we find behind the walls. We give written line-item quotes before work starts, and we do not change the price on you mid-project without a signed change order.

Yes. When a Claremont project involves excavation near protected oaks or other heritage trees, we coordinate the arborist report, tree protection plan, and any city conditions attached to the permit. This has been a standard part of our work in Claremont for years.

— Christine Yang"He caught an error in the engineer's drawings before it got framed, which would have been an expensive thing to discover later."
— Lucia Martinez"Allowances in the contract were realistic rather than artificially low to make the bid look good."
