Fast, Reliable Home Remodeling Across Sunnyvale
Home remodeling in Sunnyvale usually runs $14,000 – $45,000 for a kitchen, $9,000 – $28,000 for a bathroom, and $45,000 – $130,000 for a full addition, with permits and material spec driving the final number. We work the tract grids of 94086 and 94087, the bay-side lots of 94085 and 94089, and everything between. If you’re planning a ranch remodel, a second-story addition, or an ADU on a tight mid-century lot, call (855) 473-5620 for a free estimate. Ruben Castillo runs our Sunnyvale projects personally, and he knows which Sunnyvale overlay zones change what actually gets permitted.
Sunnyvale isn’t San Jose. The housing stock is older, the lots are smaller, and the bay air near Moffett Field chews through cheap exterior hardware faster than most homeowners expect. We plan for that from day one.
Why San Bernardino Contractors Is Sunnyvale’s Preferred Home Remodeling Company
We’ve remodeled enough 1950s and 60s ranches across Sunnyvale to know what’s behind the drywall before we open it. Galvanized supply lines patched with early copper. Knob-and-tube wiring still live in the attic. Single-story overlay zones that turn a simple second-story addition into a variance conversation with the city. None of it surprises us anymore, and none of it gets buried in a change order you didn’t see coming.
Homeowners in Sunnyvale call us because we carry the whole job. One contractor handles the kitchen, the roof, the windows, the ADU, and the hardscape. No subcontractor shuffle, no finger-pointing between a cabinet shop and a tile sub when something goes wrong. Ruben Castillo has built our Sunnyvale reputation on that single point of accountability.
We respond to Sunnyvale estimate requests within one business day. When you call (855) 473-5620, you talk to someone who has actually pulled permits in Sunnyvale, not a call center reading a script.
Styles & brands we work with
Luxury Home Remodeling in Sunnyvale
Luxury Home Remodeling in Sunnyvale means something specific here. It’s not just premium finishes. It’s the material spec that holds up against bay air on 94085 and 94089, the shear-wall work the Hayward and San Andreas faults make standard, and the finish-level choices that match what a $2.5M ranch lot in 94087 actually deserves. A luxury kitchen here runs $30,000 – $45,000 when you factor in Cambria or Silestone quartz, KraftMaid or Wellborn cabinetry, and Kohler or Grohe fixtures. A luxury bath with a walk-in shower typically lands at $18,000 – $28,000.
Sunnyvale homeowners doing luxury work tend to know their brands. They’ve researched. They ask about Caesarstone versus Cambria, GAF versus CertainTeed, PGT versus CGI. We speak that language fluently because we’re authorized to work with over 50 named manufacturers across every trade.
High-End Kitchen and Bath Packages
A Sunnyvale luxury kitchen often includes a kitchen island ($3,000 – $10,000), quartz or natural stone counters ($2,000 – $6,500), and custom cabinetry ($4,000 – $13,000). We can spec builder-grade or ultra-premium in the same conversation. You pick the brand, we handle the build.
Whole-Home Finish Coordination
When the interior and exterior both need work, luxury means consistency. Therma-Tru doors, James Hardie siding, Belgard or Techo-Bloc pavers on the patio. One contractor, every phase. The finish level stays coherent from the front door to the back fence.
Full Home Remodel in Sunnyvale
A Full Home Remodel in Sunnyvale usually means taking a 1,100-square-foot 1959 ranch and turning it into what the lot is actually worth. That’s a $45,000 – $130,000 scope when it includes a second-story addition or a full interior gut. On a 94087 lot, the permitting conversation starts with Sunnyvale’s own ADU ordinance and single-story overlay zones, not with San Jose or Mountain View rules. We know the difference, and we price accordingly.
Full home work here almost always uncovers something. Old galvanized supply lines. Undersized electrical panels. Lack of shear wall on a post-and-beam Eichler-era structure. We budget for those discoveries up front and put every allowance in writing so the draw schedule stays honest.
Second-Story Additions on Tight Lots
Sunnyvale’s small mid-century lots make second-story additions the default move for growing families. Setback and floor-area-ratio review is standard, and neighbor privacy triggers extra scrutiny. We handle the drawings, the permits, and the structural work together.
ADU and Garage Conversion Scope
An ADU in Sunnyvale runs $90,000 – $220,000, and a garage conversion lands at $30,000 – $80,000. We partner with Abodu, Dvele, Mighty Buildings, and Plant Prefab for prefab options, which is rare for a general remodeling contractor. Same single point of accountability, faster build path when the lot allows it.
Trusted Brands We Service in Sunnyvale
We stock and install parts for the brands Sunnyvale homeowners actually ask for. Roofing from GAF, CertainTeed, Owens Corning, IKO, Atlas, and Tamko. Countertops from Cambria, Silestone, and Caesarstone. Plumbing fixtures from Kohler, Moen, Grohe, Delta, American Standard, Toto, and Blanco. Hardscaping from Belgard, Unilock, Techo-Bloc, Cambridge Pavers, Tremron, and Oldcastle. That matters when you need a matching paver for a Sunnyvale patio repair or a warranty-backed shingle replacement near Moffett Field. We keep turnaround fast because we’re already on the ground here.

AfterCommon Home Remodeling Problems We See in Sunnyvale Homes
- Bay-air oxidation on exterior hardware. On 94085 and 94089 homes near tidal marsh, painted-steel window frames, gate hinges, and railing fasteners pit and corrode years ahead of the inland-spec version. We spec stainless and hot-dip galvanized hardware there, and the cost difference is small compared to replacing everything in a decade.
- Galvanized plumbing patched with early copper. In 1950s and 60s ranches across 94086 and 94087, original galvanized supply lines often have copper patches from past repairs. Mid-remodel, that turns into a repipe. We flag it before the walls open, not after.
- Missing shear wall and old wiring. Seismic exposure near the San Andreas and Hayward faults makes shear-wall upgrades and knob-and-tube-era rewiring standard scope on older Sunnyvale homes. Skipping them is a change order nobody budgeted for.
- Permit surprises on small lots. A detached ADU or second-story addition on a tight 94087 lot trips setback, floor-area-ratio, and neighbor-privacy review under Sunnyvale’s own ordinance. Contractors assuming San Jose rules get denied. We don’t.

FAQs About Home Remodeling in Sunnyvale
A bay-side remodel in 94085 or 94089 costs 5 – 12% more than the inland-spec version because exterior hardware, window frames, and railings need stainless or hot-dip galvanized finishes to survive tidal-marsh air. Skipping that spec saves money day one and costs a full hardware replacement within a decade. Call (855) 473-5620 and we’ll show you the two line items side by side.
Yes, any Sunnyvale kitchen or bath remodel that touches plumbing, electrical, or structural walls requires a city permit, and Sunnyvale enforces it. We pull all permits and pass inspections ourselves. Free estimate: (855) 473-5620.
We budget for them before we open the walls. On a 1960s ranch in the 94087 tract grid, we opened up a kitchen rough-in and found galvanized supply lines patched with early copper, so scope grew a repipe before inspection sign-off. We put the repipe change order and every allowance in writing so the draw schedule stayed honest through the surprise.
Often yes, but Sunnyvale’s own ADU ordinance and single-story overlay zones, not San Jose or Mountain View rules, decide the setbacks, floor-area-ratio, and neighbor-privacy review. We handle the drawings and the permits together. Call (855) 473-5620 to check your specific lot.
It includes interior gut, seismic shear-wall upgrades, rewiring from knob-and-tube era systems, window and door replacement, roofing, and often a second-story addition or ADU. A 94086 or 94087 Eichler-era tract home typically lands between $100,000 and $130,000 for full scope. Estimates are free: (855) 473-5620.
