Construction in Claremont, CA
Kitchen remodeling in Claremont runs $14,000-$45,000 for a full project, with smaller refreshes starting around $9,000. The number that matters most here is the one tied to the age of the house: pre-1920 Craftsman bungalows and late-Victorian homes in the Village core frequently hide knob-and-tube wiring and shallow foundations behind their original plaster, which means the written price we give you accounts for what we’ll actually find, not what a salesperson hopes we’ll find. Call (470) 298-9650 for a flat, written estimate before any tool is lifted.
Why Claremont Homes Are Different
Claremont’s housing stock spans three very different eras, and each one changes the work. The historic Village core holds late-Victorian and Craftsman homes built before 1920, where original knob-and-tube wiring, unreinforced masonry chimneys, and footings that are shallower than anything allowed today routinely surface during even a modest kitchen or bathroom project. The central grid is dominated by mid-century ranch homes, where our crews regularly deal with post-tension slab foundations and aluminum-framed windows that have lost their seals. Northern foothill parcels, above roughly the 1,500-foot line, include newer custom builds subject to California’s Wildland-Urban Interface codes: ignition-resistant wall assemblies, ember-resistant vents, and Class A roofing are mandated, not optional.
Two local realities define construction here more than anything else. First, the city sits at about 1,150 feet at the base of an alluvial fan from the San Gabriel Mountains, so subsoil shifts dramatically within a few blocks: loose gravelly outwash near the foothills, expansive clay further south. Site-specific geotechnical work is not a formality in Claremont; it is the only way to avoid guessing wrong on footing depth. Second, the Heritage Tree ordinance means a protected oak’s drip line overlapping a trench or footing excavation adds an arborist report and a tree-protection plan to the permit file. Contractors who miss that line item miss their schedule.
Our Main Claremont Services
Claremont homeowners call about two exterior projects more than any others: fences that define foothill properties and driveways that hold up under Santa Ana heat and clay movement.
Fence Installation in Claremont
Fence lines in Claremont do more than mark property. In the northern foothills, they sit inside Very High Fire Hazard Severity Zones, where ember-resistant designs and metal post options matter as much as privacy. We write fence quotes with the actual linear footage, gate count, and post depth on paper before we start, so a Heritage Oak root or a clay-heavy stretch of soil doesn’t turn into a surprise. See the full breakdown on our Fence Installation in Claremont page.

Driveway & Pavers in Claremont
Claremont’s variable subsoil, from gravelly outwash near the foothills to expansive clay south of Foothill Boulevard, is the reason driveway base prep matters more than the paver color. We compact in lifts and document what is under the finished surface, because a driveway that looks level during a mild spring can heave by October without proper base work. Our written quotes itemize the base, drainage, and material separately. Details are on the Driveway & Pavers in Claremont page.

Before
AfterKitchen Remodeling in Claremont


Kitchen remodeling in Claremont means working inside homes that were framed before a single building code existed, and that changes the project before the first cabinet is ordered. In the Village core, we frequently open a wall to find original knob-and-tube wiring or a soffit that can’t simply be removed because it is carrying the second floor. The good news is that the job becomes predictable once it is documented; our written scope describes what we will do when we find those conditions, not after. For a deeper look at the full service, visit our Kitchen Remodeling page.
Full Kitchen Remodeling
Signs you need it
Cabinets that no longer close square, a layout that keeps two people from working at once, or a floor that slopes enough to move a dropped marble are all signals the kitchen has outlived its framing era.
What it costs in Claremont
A full kitchen remodel in Claremont typically runs $14,000-$45,000, with the spread driven by whether we are reworking a compact Village galley or a 300-square-foot mid-century room.
How we do it
We open the walls to document what is really there, produce a written scope with a flat price, and only proceed once you have signed the change order for anything the inspection reveals beyond that scope.
Cabinets & Countertops
Signs you need it
Delaminating cabinet boxes, drawers that stick, or a countertop with seams that have widened past a credit card’s thickness means the surfaces have outlived their usefulness.
What it costs in Claremont
Cabinet installation runs $4,000-$13,000 and countertop installation $2,000-$6,500 in Claremont, depending on whether we are hanging stock KraftMaid boxes or fabricating a Cambria slab for a single run.
How we do it
We measure, template, and cut to the wall’s actual condition, shimming and scribing so the stone or cabinet line reads level even when the house has settled out of level.
Kitchen Design & Layout
Signs you need it
If the refrigerator door hits the island, the dishwasher blocks the only walkway when open, or the work triangle crosses itself, the layout is fighting whoever cooks there.
What it costs in Claremont
Design and layout work is built into the flat quote for any kitchen remodel in Claremont, so you are not paying a separate design fee before you ever see a number.
How we do it
We measure the existing room, map the plumbing and electrical locations, and produce a plan drawn to the actual walls, not an idealized rectangle from a stock template.
What Kitchen Remodeling Costs in Claremont
| Item | Typical range in Claremont |
|---|---|
| Full kitchen remodel | $14,000-$45,000 |
| Cabinet installation | $4,000-$13,000 |
| Countertop installation | $2,000-$6,500 |
How long does a kitchen remodel take in Claremont?
A full kitchen remodel in Claremont usually runs four to eight weeks. Homes in the Village core often add a week or two when we have to rewire old circuits or reinforce floor joists before finish work can begin. Call (470) 298-9650 for a written schedule with your estimate.
Will a kitchen remodel in Claremont trigger the Heritage Tree ordinance?
Only if the project involves grading, trenching, or foundation work under a protected tree’s drip line. Interior kitchen work typically does not trigger it. If it does, we include the arborist report and protection plan as line items in your written price.
Bathroom Remodeling in Claremont


Bathroom remodeling in Claremont frequently means opening walls in homes where the original plumbing has been in service since before 1920. In the historic Village core, we find galvanized supply lines and cast-iron waste pipes that look intact on the outside and are nearly closed on the inside, which is exactly why our written price covers the work we document, not the work we assume. See the full scope on our Bathroom Remodeling page.
Walk-In Showers & Shower Remodeling
Signs you need it
Grout lines that stay dark after cleaning, a pan that flexes, or water staining on the ceiling below are all signs the waterproofing has failed, not just the finish.
What it costs in Claremont
Walk-in shower installation runs $4,500-$12,000 and shower replacement $3,000-$8,500 in Claremont, depending on whether we are doing a curbless pan with a linear drain or a standard three-wall swap.
How we do it
We remove the existing finish down to framing, rebuild the waterproof membrane to the wall’s actual condition, and document the substrate with photos before the tile goes back on.
Tub-to-Shower Conversion
Signs you need it
A tub that nobody bathes in but everyone steps over is a solid candidate for conversion, especially in a bathroom where getting in and out of the tub is becoming a balance problem.
What it costs in Claremont
Tub-to-shower conversion runs $3,500-$10,000 in Claremont, with the range set by drain relocation, valve replacement, and whether the existing tile field has to be removed in full.
How we do it
We cap the old tub drain, frame the new shower base, and run the waterproofing up the walls before setting the floor and finish, with a photo record at every layer.
What Bathroom Remodeling Costs in Claremont
| Item | Typical range in Claremont |
|---|---|
| Full bathroom remodel | $9,000-$28,000 |
| Small bathroom remodel | $5,000-$12,000 |
| Walk-in shower installation | $4,500-$12,000 |
Does a bathroom remodel in Claremont require a permit?
Yes, any project that moves plumbing, changes the footprint, or opens load-bearing framing requires a Claremont building permit. We pull the permit, handle the inspections, and the approval is part of the written scope. Call (470) 298-9650 with your project details.
Can you remodel a bathroom in a historic Claremont home without damaging the original character?
Yes. We match trim profiles, preserve original tile where it is sound, and route new plumbing behind walls rather than through them where possible. The written scope specifies what gets protected and how.
Roofing in Claremont


Roofing in Claremont has to answer to two masters: the city’s Wildland-Urban Interface codes for northern foothill parcels, which require Class A roof assemblies and ember-resistant vents, and the Santa Ana winds that funnel out of the Cajon Pass and rip at any fastener with half an inch of play. A roof replacement here is not just a shingle swap; it is a fire and wind load calculation set against the actual condition of the decking underneath. Full details are on our Roofing page.
Roof Replacement & Installation
Signs you need it
Granule loss that fills the gutters, shingles that have lost their bond, or daylight visible through the attic decking all mean the roof has reached the end of its useful life.
What it costs in Claremont
Roof replacement runs $8,000-$20,000 in Claremont, with the final number set by square footage, roof pitch, the number of existing shingle layers being removed, and whether the code requires a Class A assembly.
How we do it
We strip the existing layers, document the decking condition with photos, replace any damaged sheathing, and install the underlayment and roofing to the fastener schedule the product manufacturer specifies for high-wind zones.
Tile Roofing
Signs you need it
Cracked or slipped tiles, broken ridge caps, or a visible sag along the ridge line means water is getting past the tile’s weather surface and into the underlayment.
What it costs in Claremont
Tile roof repair runs $600-$2,500 and full tile roof replacement $8,000-$20,000 in Claremont, depending on whether we are re-bedding a few caps or re-laying the entire field with new underlayment.
How we do it
We remove only the broken tiles, inspect the underlayment beneath, replace what has failed, and re-bed the tiles with a mortar mix matched to the existing color.
What Roofing Costs in Claremont
| Item | Typical range in Claremont |
|---|---|
| Roof replacement | $8,000-$20,000 |
| Roof repair | $400-$1,800 |
| Tile roof repair | $600-$2,500 |
Does Claremont require ember-resistant vents on re-roofs?
On parcels within the Very High Fire Hazard Severity Zones, yes. Any new or replaced vent must meet the state’s ember-resistant standard. On lower-elevation parts of Claremont, the requirement may not apply, but we spec fully ember-resistant assemblies whenever we are re-roofing in or near the foothills. Call (470) 298-9650 to confirm what applies to your parcel.
Are roofing fasteners really different in Claremont because of Santa Ana winds?
Yes. Roofing manufacturers publish separate fastener schedules for high-wind regions, and Claremont sits in the Santa Ana wind corridor from the Cajon Pass area. We install to the high-wind schedule, which usually means more fasteners per shingle and longer nails into the decking.
Windows & Doors in Claremont


Windows and doors in Claremont deal with a specific combination: pre-1920 wood-framed openings that are rarely square, and annual Santa Ana winds that push air and embers through any gap wider than a dime. A replacement project here is as much about the rough opening as it is about the glass package, because a premium window installed in an un-squared opening will leak and bind within two seasons. Full details are on our Windows & Doors page.
Window Replacement
Signs you need it
Condensation between panes, frames that have visible rot at the sill, or windows that rattle during Santa Ana gusts are all signs the seal and the rough opening have both failed.
What it costs in Claremont
Window replacement in Claremont runs $4,500-$15,000 for a typical home, with the spread set by the number of units, whether we are replacing sashes only or doing full-frame tear-outs, and the glass package chosen.
How we do it
We remove the old unit, inspect the rough opening for rot, square it with shims, and flash the opening with a continuous membrane before the new window is set and sealed.
Impact Windows & Doors
Signs you need it
Homes on the northern foothill parcels, or any Claremont house that backs up to open chaparral, should be evaluated for impact-rated glass and frames as part of the Wildland-Urban Interface code package.
What it costs in Claremont
Impact window installation runs $8,000-$25,000 in Claremont, with the range driven by the number of openings, the door count, and whether we are doing full-frame replacement or insert installations.
How we do it
We specify the glass and frame package to the code requirements for your specific fire hazard zone, then install to the manufacturer’s published anchoring schedule, not a best guess.
What Windows & Doors Costs in Claremont
| Item | Typical range in Claremont |
|---|---|
| Window replacement | $4,500-$15,000 |
| Impact window installation | $8,000-$25,000 |
| Door installation | Included with full-frame work; priced per opening |
Will new windows really cut energy costs in a Claremont mid-century ranch?
Yes, if the original windows are single-pane aluminum frames, which is common in Claremont’s mid-century stock. Replacing them with dual-pane low-e glass typically cuts the wall’s conductive heat loss by roughly a third, and the written quote will show the glass package, not just the frame style. Call (470) 298-9650 for a flat estimate.
Do I need impact windows on my Claremont home?
Only if your parcel falls within the Wildland-Urban Interface zone, which covers much of northern Claremont along the San Gabriel foothills. We confirm your zone with the city’s current hazard map and include the impact-rated package only when the code requires it.
Home Additions & ADU in Claremont

Home additions and ADUs in Claremont live or die on two documents: the geotechnical report and the Heritage Tree review. Because the city’s subsoil changes from gravelly outwash to expansive clay within a few blocks, the footing depth on a new addition cannot be borrowed from a neighbor’s project, and any excavation that grazes a protected oak’s drip line adds an arborist report to the permit set. The work is worth it; a properly permitted ADU in Claremont typically adds square footage that rents or houses family for decades. See the full breakdown on our Home Additions & ADU page.
ADU Design & Permitting
Signs you need it
If you have a detached garage, a deep rear yard, or an existing structure that is underused, you likely have a viable ADU site, but only a plan set drawn to your actual lot dimensions will confirm it.
What it costs in Claremont
ADU construction runs $90,000-$220,000 in Claremont, with design and permitting included as line items in the written quote, not billed separately as a surprise.
How we do it
We survey the lot, run the geotechnical investigation, pull the arborist report where required, and submit a permit set that reflects what the city will actually approve.
Garage Conversion ADU
Signs you need it
A detached garage with a sound slab and a roofline that can accept dormers or a raised ridge is a candidate for conversion when the lot’s rear yard is too narrow for a separate ground-up build.
What it costs in Claremont
Garage conversions in Claremont run $30,000-$80,000, with the spread driven by whether the existing slab meets current footing requirements or has to be reinforced or replaced.
How we do it
We document the existing slab and roof structure, bring the foundation up to code where required, and build the living envelope inside the existing footprint with a new electrical service run and separate metering.
What Home Additions & ADU Costs in Claremont
| Item | Typical range in Claremont |
|---|---|
| Home addition | $45,000-$130,000 |
| ADU construction | $90,000-$220,000 |
| Garage conversion | $30,000-$80,000 |
How long does ADU permitting take in Claremont?
ADU permitting in Claremont typically runs three to six months from submission to issued permit, longer if the project triggers Heritage Tree review or geotechnical corrections. We submit the full set at once to avoid resubmittal cycles. Call (470) 298-9650 for a written estimate and schedule.
Will adding an ADU affect my property taxes in Claremont?
Yes. Adding an ADU in Claremont triggers a reassessment of the new square footage under Proposition 13 rules, not a full-property reassessment in most cases. We can’t give tax advice, but we can point you to the right county assessor’s office and schedule the work.

In Claremont, the two biggest price movers are the age of the house and the condition of the subsoil. Pre-1920 homes carry rewire and footing surprises; clay-heavy southern parcels expand and contract with the seasons. Under Clause 1 of the Haven Standard, the written price is delivered before anyone starts, so those variables are priced on paper, not discovered on a job site.
