Fast, Reliable General Contractor Across Sunnyvale
A full-scope general contractor in Sunnyvale handles everything from a 94087 kitchen expansion to a ground-up ADU in the 94085 corridor, and the job typically runs anywhere from $14,000 for a modest kitchen remodel to $220,000 for a complete prefab or stick-built accessory dwelling unit. Call Nate Calloway and the Spruce Contractors team at (877) 265-5771 for a free, line-item estimate before you commit to anything. We know the difference between a 1962 Eichler-style post-and-beam and a 2015 infill townhome, because we work on both every month.

Why Spruce Contractors Is Sunnyvale’s Preferred General Contractor Company
Sunnyvale homeowners keep calling us back because we run the whole property under one contract. That means the same foreman who opens your kitchen wall for a Cambria countertop install is the one coordinating the roofer on your Owens Corning re-shingle. No finger-pointing between subs. No “that’s the other guy’s trade.” We’re state-licensed, insured and bonded, and Nate Calloway signs off on every scope before materials get ordered.
Our Sunnyvale customers tend to be research-driven. They’ve already looked up cabinet lead times. They know what Silestone costs per slab. They want a contractor who can talk KraftMaid box construction and Schluter waterproofing in the same sentence as a load calculation for a heat pump. That’s exactly the conversation we’d rather have.
We respond to Sunnyvale neighborhoods including the 94086 and 94087 ranch tracts, the north 94085 townhome corridor, and the older pockets around El Camino Real and Wolfe Road. Most estimates are scheduled within a few business days. We’re not the cheapest bid you’ll get, and we’re comfortable with that. We quote a fixed price in writing and we hold it.

Residential General Contractor in Sunnyvale
Residential general contractor work in Sunnyvale is different from anywhere else because the city’s all-electric reach code collides with 1950s and 60s housing stock in specific, expensive ways. When a homeowner in the 94086 or 94087 tract swaps a gas range for induction, that single appliance change can trigger a panel upgrade, permit-level electrification review, and re-wiring scope that a less experienced contractor might not flag until the walls are open. Here, the schedule is set by millwork and glass lead times, not labor. We fix the price and allowances in writing before any long-lead item gets ordered.
What you can expect to pay in Sunnyvale depends on which sub-service you’re actually buying. A kitchen remodel runs $14,000 – $45,000. Cabinet installation alone is $4,000 – $13,000. Countertop installation sits between $2,000 and $6,500. If you’re expanding the footprint, a home addition in Sunnyvale runs $45,000 – $130,000, and an ADU starts at $90,000 and tops out around $220,000 depending on whether you go stick-built or a prefab system from Mighty Buildings, Boxabl, or Plant Prefab.
Custom Millwork and Cabinetry
On a high-end Sunnyvale kitchen, KraftMaid and Wellborn cabinets don’t come off a shelf. They’re ordered to spec after we confirm panel-ready appliance dimensions, the exact reveal on your flush-inset doors, and the finish sample you signed off on. That order locks a 12 – 20 week lead time. So we order before demolition, not after.
Architectural Glass and Specialty Finishes
If your remodel calls for a steel-and-glass partition, a custom shower enclosure, or a floor-to-ceiling window wall, the glass is the longest lead item on the job. We coordinate with the fabricator early and hold the draw schedule to the delivery date, not to rough-in completion. That’s how you avoid idle crews and a blown timeline.
Hire a General Contractor in Sunnyvale
Homeowners hire a general contractor in Sunnyvale when the job crosses trade lines and they don’t want to manage five separate specialists. A remodel that touches plumbing, electrical, framing, drywall, and finishes needs one accountable party. We quote a fixed price with written allowances for every finish category before we order anything. Change orders are documented and priced before work proceeds. That discipline is what keeps a $45,000 kitchen from becoming a $70,000 dispute.
Here’s the pricing structure we use on Sunnyvale jobs. A bathroom remodel runs $9,000 – $28,000. A kitchen remodel spans $14,000 – $45,000. A home addition runs $45,000 – $130,000, and an ADU starts at $90,000 and tops out around $220,000. Those numbers include labor and materials from our vetted brand network. They don’t include surprise change orders, because we don’t work that way.
Fixed Price Before Ordering
We won’t start demolition on a Sunnyvale remodel until the long-lead items are priced, selected, and ordered. That means your Cambria slab is reserved, your KraftMaid order is in the queue, and your Moen fixtures are on the PO. The price you sign is the price you pay, barring a change you initiate.

Allowance Schedule in Writing
Every finish category gets a written allowance: tile, plumbing fixtures, lighting, hardware, countertops, paint. You pick within the allowance, or you upgrade and sign a change order before we spend your money. No ambiguity. No end-of-job surprises.
Trusted Brands We Service in Sunnyvale
Spruce Contractors works with more than 50 name-brand manufacturers, and we stock common replacement parts and hardware locally so Sunnyvale customers aren’t waiting on a cross-country shipment for a drawer slide or a window sash. On the prefab side, we’re one of the few general contractors offering ADU systems from Mighty Buildings, Boxabl, Plant Prefab, and Tuff Shed. Each carries different lead times and build specs. We’ll walk you through the trade-offs, including which brands fit Sunnyvale’s permitting path and which don’t.

AfterCommon General Contractor Problems We See in Sunnyvale Homes
- Gas-to-electric swaps triggering full panel upgrades. In the 94086 and 94087 Eichler-style tracts, swapping a gas range for induction can pull a permit-level electrification review and a 200-amp panel replacement. We flag it in the estimate, not after drywall is up.
- Custom millwork lead times blowing the schedule. KraftMaid and Wellborn orders run 12 – 20 weeks. We order at contract signing and hold the draw schedule to delivery. A contractor who orders after demo is already late.
- Radiant slab heating under remodeled floors. In 1950s-60s ranch homes, concrete slabs often carry hydronic heating lines exactly where you want to cut a footing or move a drain. We locate and map those lines before saw-cutting.
- Sketchy allowances creating end-of-job disputes. Without a written finish schedule, a homeowner can approve one price and get billed another. Every allowance is on paper and signed before we order anything.

FAQs About General Contractor in Sunnyvale
We treat it as an electrical project first. When you swap gas for induction in a 94086 or 94087 ranch, we evaluate your panel capacity, the run from panel to kitchen, and whether the city’s permit-level electrification review will require additional upgrades. That work goes into the estimate before you sign, not as a change order after demo. Call (877) 265-5771 and we’ll walk your specific home’s panel situation on the first visit.
The cabinet order. KraftMaid and Wellborn custom lines run 12 – 20 weeks from the day we release the order. We order at contract signing and hold the draw schedule to millwork delivery. If your kitchen is designed around a specific Cambria slab or architectural glass partition, those lead times stack. We sequence all of it before the first hammer swings. Call (877) 265-5771 to get your schedule mapped.
Yes. Every Sunnyvale job gets a finish schedule with written allowances for tile, plumbing fixtures, lighting, hardware, countertops, and paint. You choose within the allowance. If you upgrade, we price the change order and you sign before we spend. It’s how we avoid end-of-project disputes. Call (877) 265-5771 for a sample allowance schedule.
It can move your layout. In 1950s-60s ranch homes, hydronic heating lines run through the concrete slab exactly where you might want a new footing, a drain relocation, or an island. Before we cut, we map the loop layout. On a 1962 Eichler-style home in the 94087 tract, our crew opened a load-bearing wall for a kitchen expansion and found radiant loops directly under the planned island footing. We shifted the island 18 inches east, re-routed the slab sensor wiring, and held the draw schedule to the KraftMaid and Cambria delivery. Call (877) 265-5771 if your slab needs that kind of attention.
Expect a longer, more detailed review than a neighboring city. Sunnyvale’s One-Stop Permit Center and the city’s climate-action goals mean ADUs and additions get scrutinized for all-electric compliance, solar readiness, and EV-capable wiring. We pull the permits, attend the inspections, and build to the city’s current reach code requirements. Call (877) 265-5771 to find out what your specific lot will trigger.
