AfterConstruction in Sunnyvale, CA
Kitchen remodeling in Sunnyvale typically runs $14,000-$45,000 for a full job, while bathroom remodels land between $9,000-$28,000. What makes Sunnyvale different is the housing stock: thousands of 1950s-1970s single-story ranch homes on slab foundations, many with original galvanized plumbing and aluminum wiring, now sitting on lots worth $1.5M-$3M. Replacing systems and opening walls in these homes is standard work here, and the written price should reflect that reality before anyone swings a hammer. Call (470) 298-9650 for a flat written quote on any of the five trades below.
Why Sunnyvale Homes Are Different
The dominant Sunnyvale home is a 1950s-1970s ranch, single story, low-pitch roof, slab or cripple-wall foundation. In neighborhoods like Birdland, Finch Avenue and Wren Avenue hold block after block of these original homes, many with corroded galvanized supply lines from decades of the Bay Area’s moderately hard water. The dry season is long here, so exterior work like roofing and siding can run nearly year-round, but the northern edges of Sunnyvale near the Bay sit over bay mud and hydraulic fill. That soil condition means any addition or second-story project in those pockets needs a geotechnical report and an engineered foundation, which adds cost and schedule compared to a hillside city to the west.
What drives most Sunnyvale construction decisions is the land-to-structure ratio. A 1,000-square-foot original ranch on a lot worth $2M changes the math on a kitchen remodel or an ADU. Homeowners here aren’t fixing up a house they might sell in five years; they’re upgrading a structure that sits on land worth several times what the house itself is worth. That makes mid-range and high-end remodels the default, not the exception.
Our Main Sunnyvale Services
Two jobs Sunnyvale homeowners call about most are fence installation and driveway work, and each has its own dedicated page with full pricing and local detail.
Fence Installation in Sunnyvale
Fencing in Sunnyvale means working with slab foundations and long, flat lots where property lines are often marked by aging redwood fences from the original build era. Rot at the post base is common, especially in the irrigated clay soils of the older ranch neighborhoods. We quote vinyl fence installation at $3,500-$9,000 and aluminum at $4,000-$10,000, both written before work starts. Full local detail is on the Fence Installation in Sunnyvale page.
Driveway & Pavers in Sunnyvale
Driveways in Sunnyvale run the range from cracked concrete slabs poured in the 1960s to paver jobs on new ADU-adjacent properties. Concrete replacement runs $4,500-$12,000, paver driveways $7,000-$18,000, and paver patios $3,500-$11,000. The long dry season means paver work schedules reliably here. See the Driveway & Pavers in Sunnyvale page for line-item pricing and local permitting notes.

BeforeAfterKitchen Remodeling in Sunnyvale
A full kitchen remodel in Sunnyvale runs $14,000-$45,000, with smaller partial jobs starting around $9,000. Most of the kitchens we open up in Birdland and other 1950s-1970s ranch neighborhoods have original galvanized supply lines that have corroded inward, plus aluminum branch wiring that needs replacement when walls come down. That’s why a Sunnyvale kitchen quote often includes plumbing and electrical scope a newer home wouldn’t. Our written price covers the full scope before work starts: Under Clause 1 of The Haven Standard, you get a flat number, a written scope, and a written warranty. This work sits inside our broader Kitchen Remodeling practice.
Full Kitchen Remodeling
Signs you need it
Original 1960s cabinets with failing drawer slides, a layout that closes off the living room, or galvanized supply lines that have reduced flow to a trickle.
What it costs in Sunnyvale
A full kitchen remodel in Sunnyvale runs $14,000-$45,000 depending on cabinet line, countertop material, and whether plumbing and electrical need full replacement.
How we do it
We demo to the studs, replace or reroute supply lines and wiring as needed, then install cabinets, countertops, tile, fixtures, and trim in sequence with a documented photo record at each inspection point.
Cabinets & Countertops
Signs you need it
Water-damaged particleboard boxes, delaminating thermofoil doors, or laminate counters that have worn through at the sink.
What it costs in Sunnyvale
Cabinet installation runs $4,000-$13,000 and countertop installation $2,000-$6,500 in Sunnyvale.
How we do it
We remove existing cabinets and counters, verify the wall framing, install new boxes level and anchored to studs, then template and set the new countertop with a written seam plan.
What Kitchen Remodeling Costs in Sunnyvale
| Item | Typical range in Sunnyvale |
|---|---|
| Full kitchen remodel | $14,000 - $45,000 |
| Small kitchen remodel | $9,000 - $20,000 |
| Cabinet installation | $4,000 - $13,000 |
How long does a kitchen remodel take in Sunnyvale?
Most Sunnyvale kitchen remodels run 4 to 8 weeks, but homes in northern Sunnyvale with bay-mud soil issues don’t affect kitchen work unless we’re cutting into the slab for plumbing moves. Call (470) 298-9650 for a schedule tied to your written scope.
Will a kitchen remodel trigger rewiring in Sunnyvale?
Frequently, yes. Many 1950s-1970s Sunnyvale ranches have original aluminum branch wiring, and any wall we open must be brought to current code. We include that in the written quote before demolition starts. Call (470) 298-9650 for an exact figure.
Bathroom Remodeling in Sunnyvale
A bathroom remodel in Sunnyvale runs $9,000-$28,000, with small bathrooms at $5,000-$12,000. The typical job is a 5-foot by 8-foot hall bath in a 1960s ranch with original cast-iron drain lines and a tub that has been reglazed twice. Our Bathroom Remodeling practice starts every Sunnyvale project with a written price and a written scope, including the plumbing repairs these homes usually need.
Walk-In Showers & Shower Remodeling
Signs you need it
Crumbling grout around a 50-year-old tub surround, a shower pan that has leaked onto the subfloor, or a homeowner who wants a curbless entry for aging in place.
What it costs in Sunnyvale
Walk-in shower installation runs $4,500-$12,000 and shower replacement $3,000-$8,500 in Sunnyvale.
How we do it
We demo to the studs, inspect and replace the drain assembly and subfloor as needed, install a waterproof membrane, then set tile, glass, and fixtures with a written waterproofing record.
Tub-to-Shower Conversion
Signs you need it
A cast-iron tub that has chipped enamel, a showerhead stuck at tub height, or mobility concerns that make stepping over a tub wall unsafe.
What it costs in Sunnyvale
Tub-to-shower conversion runs $3,500-$10,000 in Sunnyvale depending on tile selection and whether the drain line needs reconfiguration.
How we do it
We remove the tub, reset the drain for a shower, rebuild the valve wall, then waterproof and tile the new shower with a documented photo record of the membrane before tile goes up.
What Bathroom Remodeling Costs in Sunnyvale
| Item | Typical range in Sunnyvale |
|---|---|
| Full bathroom remodel | $9,000 - $28,000 |
| Small bathroom remodel | $5,000 - $12,000 |
| Walk-in shower installation | $4,500 - $12,000 |
Do Sunnyvale bathrooms need cast-iron drain replacement?
Often yes. Original cast-iron drains in 1950s-1970s ranches have typically rusted through at the hub joints by now, and we inspect before quoting. Call (470) 298-9650 for a written estimate that includes whatever the drain camera shows.
Can a small Sunnyvale bathroom get an accessible shower?
Yes, and it’s one of the most common requests in older ranch homes where the original 5-by-8 footprint is the only bathroom on the hall. The number is in the written quote before we start. Call (470) 298-9650.
Roofing in Sunnyvale
A roof replacement in Sunnyvale runs $8,000-$20,000, and a roof repair $400-$1,800. Most homes here have low-pitch roofs with composition shingles laid over a single layer, but many have a second layer added in the 1980s, which means a tear-off is the standard scope, not an upgrade. The long dry season gives Sunnyvale a wide working window for exterior work. Our Roofing practice quotes a flat number with the tear-off, underlayment, flashing, and warranty in writing.
Roof Replacement & Installation
Signs you need it
Granule loss in the gutters, curling shingle edges, or a roof that has reached its twentieth year on a low-pitch Sunnyvale ranch.
What it costs in Sunnyvale
Roof replacement runs $8,000-$20,000 in Sunnyvale depending on square footage, layer count, and whether sheathing needs replacement.
How we do it
We tear off to the deck, replace damaged sheathing, install underlayment and flashing, then lay the new shingle system with a written layer count and a photo record of the deck before it’s covered.
Roof Repair
Signs you need it
A leak stain on the ceiling, lifted flashing around a chimney or vent, or missing shingles after a winter wind event.
What it costs in Sunnyvale
Roof repair runs $400-$1,800 in Sunnyvale depending on the leak source and how much flashing or shingle work is involved.
How we do it
We locate the leak, replace the damaged flashing or shingles, and seal the repair with a written description of what was found and what was done, plus photos.
What Roofing Costs in Sunnyvale
| Item | Typical range in Sunnyvale |
|---|---|
| Roof replacement | $8,000 - $20,000 |
| Roof repair | $400 - $1,800 |
| Metal roof installation | $15,000 - $40,000 |
Do Sunnyvale ranch roofs need a tear-off or can you roof over?
Most need a tear-off. A high share of Sunnyvale’s 1950s-1970s ranches have two shingle layers already, so building a third is not code-compliant. We write the tear-off into the flat price. Call (470) 298-9650 for a roof assessment.
How long does a Sunnyvale roof replacement take?
Most roof replacements run 2 to 5 days depending on size and weather, and Sunnyvale’s dry season keeps schedules reliable from spring through fall. Call (470) 298-9650 for a written timeline with your quote.
Windows & Doors in Sunnyvale
Window replacement in Sunnyvale runs $4,500-$15,000 for a typical ranch home, and impact window installation $8,000-$25,000. The original aluminum-framed single-pane windows on most 1960s Sunnyvale homes have thermally failed, and the dry, sunny climate has baked the seals. Our Windows & Doors practice writes the full job, including stucco repair around the new frames, into the flat price.
Window Replacement
Signs you need it
Single-pane aluminum frames that sweat in winter, sashes that no longer open, or rising PG&E bills in a house with original 1960s glazing.
What it costs in Sunnyvale
Window replacement runs $4,500-$15,000 in Sunnyvale depending on window count, frame material, and whether stucco or trim repair is needed.
How we do it
We remove the old frames, inspect the rough opening, install the new windows with proper flashing at the stucco line, and finish the interior and exterior trim.
Door Installation
Signs you need it
A front door that has warped from decades of direct sun, an original hollow-core interior door set that transmits every sound, or a slider that no longer rolls.
What it costs in Sunnyvale
Door installation in Sunnyvale typically falls within the $4,500-$15,000 overall window-and-door range depending on how many doors and whether the rough opening needs reframing.
How we do it
We set the new door in the existing opening, shim and level it, install new hardware, and weatherstrip with a written note on any framing corrections made.
What Windows & Doors Costs in Sunnyvale
| Item | Typical range in Sunnyvale |
|---|---|
| Window replacement | $4,500 - $15,000 |
| Impact window installation | $8,000 - $25,000 |
| Door installation | $4,500 - $15,000 |
Do Sunnyvale stucco homes need special window flashing?
Yes. Most Sunnyvale ranches are stucco over framing, and the old window flanges were often papered in without proper pan flashing. We detail the flashing in the written scope. Call (470) 298-9650 for a full window assessment.
Can I replace windows one room at a time in Sunnyvale?
Yes, and it’s a common approach in older homes where the budget is staged. The price per window is written and fixed, and each phase gets its own signed change order. Call (470) 298-9650 for a phased plan.
Home Additions & ADU in Sunnyvale
A home addition in Sunnyvale runs $45,000-$130,000, and a detached ADU $90,000-$220,000. Sunnyvale has one of the faster ADU approval processes in Santa Clara County, with pre-approved plans available, but the trigger thresholds for fire sprinklers and the 4-foot minimum rear and side setbacks in R-0/R-1 zones still catch out-of-area crews. Our Home Additions & ADU practice starts with the geotechnical and permit path written into the quote.
New Detached ADU
Signs you need it
A Sunnyvale lot large enough for a rear-yard unit, a homeowner who wants rental income or an aging parent close by, and a lot value that justifies the build.
What it costs in Sunnyvale
ADU construction runs $90,000-$220,000 in Sunnyvale depending on size, foundation type, and whether the site requires bay-mud geotechnical work.
How we do it
We run the geotech report if the site is north of Highway 101, handle the permit submittal and fire-sprinkler design, then build the unit with a signed change order process throughout.
Garage Conversion ADU
Signs you need it
An attached or detached garage that no longer holds cars, and a homeowner who wants a rental unit without building a new foundation.
What it costs in Sunnyvale
Garage conversion runs $30,000-$80,000 in Sunnyvale depending on whether the slab needs raising, the electrical service needs upsizing, and if sewer lines need extension.
How we do it
We assess the slab and framing, design the conversion, handle the permit set, then build out the unit with a written photo record and a fixed price.
What Home Additions & ADU Costs in Sunnyvale
| Item | Typical range in Sunnyvale |
|---|---|
| Home addition | $45,000 - $130,000 |
| ADU construction | $90,000 - $220,000 |
| Garage conversion | $30,000 - $80,000 |
Does Sunnyvale require fire sprinklers in ADUs?
It depends on the trigger thresholds, which hinge on the main house and the ADU’s size and separation. We confirm the specific requirement for your lot before the quote is written. Call (470) 298-9650 for a permit-path review.
Will a detached ADU in Sunnyvale need a geotechnical report?
Often yes, especially north of Highway 101 where bay mud and hydraulic fill create liquefaction concerns. The report gets ordered during the written-quote phase so the price is honest. Call (470) 298-9650.
