Construction in San Jose, CA
Kitchen remodeling in San Jose runs $16,520 to $53,100 for a full job, and what drives that range is the house itself: most kitchens sit inside post-WWII ranch and tract homes built between 1948 and 1975, with raised cripple-wall foundations, aging electrical panels, and floor joists that have settled unevenly on Altamont-series clay. We quote a flat written price before any work starts, because a San Jose kitchen rarely opens up without revealing something the original builder hid. Call (470) 298-9650 for a written estimate.
Why San Jose Homes Are Different
San Jose sits on the Santa Clara Valley floor, where expansive Altamont clay shrinks during the dry summer and heaves when winter rain returns. That cycle moves foundations, cracks stucco, and racks door frames more aggressively here than in coastal Santa Cruz or the Los Gatos foothills. Homes built from the late 1940s through the 1970s dominate neighborhoods like Berryessa, Cambrian, and East San Jose, and most sit on cripple-wall foundations that predate modern seismic code. Between the Hayward Fault to the east and the Calaveras system to the south, the structural questions are not optional on any remodel.
Willow Glen and pockets near downtown hold older Victorian and Craftsman houses with lath-and-plaster walls and knob-and-tube wiring, which changes how we open a wall or run a circuit. Almaden Valley and South San Jose push into hillside terrain where cut-and-fill grading complicates drainage and addition footings. The permit desk is backed up more than neighboring cities because San Jose runs one of California’s highest-volume ADU pipelines alongside a mandatory Soft-Story Retrofit Ordinance. Any contractor working here juggles structural retrofits on legacy housing with premium backyard-unit builds for tech-economy homeowners, often on the same block.
Our Main San Jose Services
Two services generate the most calls from San Jose homeowners: fence installation and driveway and pavers work, both shaped by the same clay soil, property-line setbacks, and aging housing stock.
Fence Installation in San Jose
Fence posts in San Jose move with the soil. The Altamont clay that heaves each winter will lean a post set too shallow, so we set posts below the expansion zone and use concrete collars sized for the load. Property lines in older neighborhoods like Cambrian and Berryessa often run at odd angles, and we verify every boundary before digging. Redwood and vinyl dominate locally; vinyl fencing runs $4,130 to $10,620. For a written price on your fence, see Fence Installation in San Jose.

Driveway & Pavers in San Jose
Driveways fail in San Jose when water meets clay. A cracked slab is rarely just cosmetic, it usually means poor drainage under the pour, and the heave cycle will widen it every year. Paver driveways run $8,260 to $21,240; concrete runs $5,310 to $14,160. We compact the base, slope for drainage, and document every layer with a photo record before covering it. For a detailed written quote, see Driveway & Pavers in San Jose.

AfterKitchen Remodeling in San Jose


Kitchen remodeling in San Jose means working inside a house built when kitchens were 80 square feet, panel boxes were 60 amps, and the floor had settled decades before you bought it. Most kitchens in Berryessa, Cambrian, and East San Jose sit on raised foundations where the stove wall has drifted half an inch out of level, and the clay soil under the slab is still moving. That is the real work: opening the room, correcting the framing and subfloor, upgrading the electrical, and then installing cabinetry and counters that will not rack. A full kitchen remodel runs $16,520 to $53,100 in this market; a small kitchen runs $10,620 to $23,600. Under Clause 1 of The Haven Standard, the price is written before anyone starts, and no change proceeds without a signed change order. We use KraftMaid and Wellborn cabinets and Cambria or Caesarstone counters, and the warranty is printed on the quote, not implied. See Kitchen Remodeling for the full scope of our work.
Cabinets & Countertops
Signs you need it
Cabinet faces delaminate, drawers bind, or the counter has a crack running from the sink cutout.
What it costs in San Jose
Cabinet installation runs $4,720 to $15,340 and countertop installation $2,360 to $7,670.
How we do it
We remove the old boxes, shim the base level on the settled floor, set the new cabinets, and template counters only after the cabinets are installed and locked.
Backsplash, Tile & Flooring
Signs you need it
Grout is cracking along the counter line, or the tile was set over drywall that is now soft behind the sink.
What it costs in San Jose
Backsplash installation runs $945 to $2,950; tile flooring work is quoted per square foot at the site visit.
How we do it
We strip to the substrate, check for moisture behind the sink wall, install cement board where needed, and set tile with a waterproofing membrane at wet zones.

| Kitchen island installation | $3,540 - $11,800 |
How long does a kitchen remodel take in San Jose?

Will you pull the permits for a San Jose kitchen remodel?
Yes. We pull all required permits, and the permit record is part of your documentation package. For a written price that includes permitting, call (470) 298-9650.
Bathroom Remodeling in San Jose


Bathroom remodeling in San Jose runs $10,620 to $33,040 for a full job, and the first thing we check is the subfloor because a 1950s or 1960s bathroom in Berryessa or Cambrian usually hides rotted plywood under the tile. Clay soil heave, original cast-iron drain lines, and decades of shower steam have done their work behind the walls. A small bathroom remodel runs $5,900 to $14,160, and we quote a flat price with a written scope before demolition starts. See Bathroom Remodeling for the full service breakdown.
Walk-In Showers & Shower Remodeling
Signs you need it
Tile is pulling away from the curb, or the shower pan flexes when you stand in it.
What it costs in San Jose
Walk-in shower installation runs $5,310 to $14,160; shower replacement runs $3,540 to $10,030.
How we do it
We remove the old pan and tile, inspect the subfloor and joists, replace any water-damaged framing, then install a waterproof membrane, drain, and tile with a documented photo record at each step.
Tub-to-Shower Conversion
Signs you need it
The tub is chipped, the surround is failing, or the household needs a curbless entry for mobility.
What it costs in San Jose
Tub-to-shower conversion runs $4,130 to $11,800.
How we do it
We pull the tub, rebuild the drain to a 2-inch shower line, waterproof the entire wet area, and set a finished floor that meets the slope requirement.
What Bathroom Remodeling Costs in San Jose
| Item | Typical range in San Jose |
|---|---|
| Full bathroom remodel | $10,620 - $33,040 |
| Small bathroom remodel | $5,900 - $14,160 |
| Bathroom vanity installation | $945 - $3,540 |
Do bathroom remodels in San Jose have hidden water damage?
Often, yes. Original cast-iron drains and tile set over drywall were common in 1950s and 1960s tract homes, and the damage is not visible until we open the wall. We document what we find with photos and price any added work through a signed change order.
Can I get a written price before demolition starts?
Yes. Every bathroom remodel receives a flat written price and written scope before any work begins. Call (470) 298-9650 for a quote.
Roofing in San Jose


Roof replacement in San Jose runs $9,440 to $23,600, and the local variable is heat and dry rot more than rain. Comp shingles on a 1960s ranch in Cambrian or East San Jose bake through the dry season at valley-floor temperatures, and the fascia and soffit behind them are often original, unpainted, and quietly rotting. Tile roof repair runs $710 to $2,950, and we see cracked tiles from the heave cycle on nearly every older roof we inspect. See Roofing for our full roofing scope.
Roof Repair
Signs you need it
You see granule loss in the gutter or a water stain on the ceiling after rain.
What it costs in San Jose
Roof repair runs $470 to $2,125.
How we do it
We locate the entry point, remove the affected shingles or tiles, replace the underlayment at the penetration, and seal with a documented photo record of the repair.
Roof Replacement & Installation
Signs you need it
Shingles are curling, or the roof has two layers already and the decking is soft in places.
What it costs in San Jose
Roof replacement runs $9,440 to $23,600; metal roof installation runs $17,700 to $47,200.
How we do it
We strip to the decking, replace rotted sheathing, install new underlayment and flashing, and lay the new system with the manufacturer’s wind and fire ratings intact.
What Roofing Costs in San Jose
| Item | Typical range in San Jose |
|---|---|
| Roof replacement | $9,440 - $23,600 |
| Roof repair | $470 - $2,125 |
| Tile roof repair | $710 - $2,950 |
Do San Jose roofs need special underlayment?
Valley-floor heat and the wet winter cycle make a high-temperature, self-sealing underlayment worth the cost on most San Jose homes. We quote the material by name and put it in the written scope.
How long does a roof replacement take in San Jose?
Most asphalt shingle replacements finish in two to four days. Tile and metal run longer. The schedule is written into your quote. Call (470) 298-9650 for a written price.
Windows & Doors in San Jose


Window replacement in San Jose runs $5,310 to $17,700, and the deciding factor on a 1950s or 1960s house is usually the rough opening, because original wood frames in Berryessa and Willow Glen have settled with the clay and are no longer square. Single-pane aluminum sliders from the tract era lose heat in winter and leak dust through dry summer months. Impact window installation runs $9,440 to $29,500 and makes sense for homes near older tree stock or on exposed hillside lots. See Windows & Doors for the full window and door scope.
Window Replacement
Signs you need it
Frames are racked, glass is single-pane, or you feel a draft even when the sash is closed.
What it costs in San Jose
Window replacement runs $5,310 to $17,700.
How we do it
We measure each opening, square the frame where needed, set the new unit plumb, insulate the perimeter, and trim with a documented photo record.
Impact Windows & Doors
Signs you need it
Your lot is exposed, you hear street noise through closed windows, or your insurance carrier asks about impact ratings.
What it costs in San Jose
Impact window installation runs $9,440 to $29,500.
How we do it
We specify impact-rated units, install with the manufacturer’s anchoring schedule, and verify the gasket and weep system before trim goes on.
What Windows & Doors Costs in San Jose
| Item | Typical range in San Jose |
|---|---|
| Window replacement | $5,310 - $17,700 |
| Impact window installation | $9,440 - $29,500 |
| Door installation | $5,310 - $17,700 |
Will new windows fix the racked frames on my San Jose house?
New windows square up the opening, but they do not fix the settling that caused the racking. We level the frame before setting the unit and flag any foundation movement that needs attention. Call (470) 298-9650 for an assessment and written price.
Do you install windows in older San Jose homes with lath-and-plaster walls?
Yes. The trim detail changes, and we protect the plaster during removal, but the installation is the same: square the opening, set plumb, insulate, and trim.
Home Additions & ADU in San Jose

ADU construction in San Jose runs $106,200 to $259,600 for a detached unit, and this is now one of the highest-volume ADU permit cities in the state, driven by the Silicon Valley housing shortage and state laws that override most local restrictions. A home addition runs $53,100 to $153,400, and the local complication is the soil: hillside lots in Almaden Valley and South San Jose sit on cut-and-fill grading that requires geotechnical review before footings are dug. Garage conversions run $35,400 to $94,400 and usually need structural upgrades to the existing slab and cripple walls. See Home Additions & ADU for the full service scope.
ADU Design & Permitting
Signs you need it
You have a rear yard with access, and you want a legal rental unit rather than an informal in-law setup.
What it costs in San Jose
ADU construction runs $106,200 to $259,600 including design, engineering, and permit fees.
How we do it
We run a site check, handle design and engineering, submit the permit package, and return a flat written price before any site work begins.
Garage Conversion ADU
Signs you need it
Your garage is detached or attached with its own entry, and the existing slab is in decent shape.
What it costs in San Jose
Garage conversion runs $35,400 to $94,400.
How we do it
We evaluate the slab and cripple walls, upgrade the structure to current code, run new utilities, and build out the interior as a permitted dwelling unit.
What Home Additions & ADU Costs in San Jose
| Item | Typical range in San Jose |
|---|---|
| Home addition | $53,100 - $153,400 |
| ADU construction | $106,200 - $259,600 |
| Garage conversion | $35,400 - $94,400 |
Do San Jose ADUs require special foundation work?
Often, yes. The Altamont clay under the valley floor expands and contracts enough to crack a standard slab over time. We specify a foundation design that accounts for the soil movement before we pour.
Can Rowan handle the San Jose permit process for an ADU?
Yes. We handle the permit package from drawings through final inspection, and the permit record is part of your documentation. Call (470) 298-9650 for a written price.

We install and service prefab and panelized ADU systems from Abodu, Cover, Dvele, and Mighty Buildings, and we stock common replacement parts for these systems locally in the Bay Area. Turnaround on branded parts is typically three to five business days. See our brands for the full list.
