AfterQuartz & Granite Countertops in Sunnyvale, CA
Quartz and granite countertop installation in Sunnyvale typically runs between $65 and $175 per square foot installed, depending on the material, edge profile, and whether the existing substrate needs reinforcement. Most kitchen countertop projects in Sunnyvale are completed in two visits – one for templating and one for installation – and the full written price is on paper before either visit is scheduled. If you want a number to work with before calling anyone, call Rowan Construction Group Sunnyvale at (650) 405-3637. We give you that number in writing, not over your shoulder at a showroom.
This page covers quartz and granite specifically – two very different materials that often get lumped together – as part of our broader Kitchen Remodeling in Sunnyvale work. Choosing between them isn’t just a style decision. It affects maintenance, resale, structural loading, and what your cabinets need to support underneath. We work through those specifics during templating so the quote reflects the actual job, not a best-case estimate.
Grant Rowan founded Rowan Construction Group in 2007, and since then we’ve completed 4,000-plus projects under one consistent rule: a written price before any work starts, on every trade, every time. That rule applies here the same way it applies to Kitchen Remodeling services, a full kitchen gut, or a roofing replacement.
When You Need Quartz & Granite Countertops
Not every countertop situation is the same, and in Sunnyvale – where home prices reward careful upgrades – the reasons to replace or upgrade countertops vary by neighborhood, home age, and how the kitchen is actually used. Some homeowners start with Small & Partial Kitchen Remodels and expand from there. Here are the scenarios where we see homeowners call most often:
- Laminate that has delaminated or swollen near the sink. This is common in Sunnyvale homes built in the 1970s and 1980s, particularly in the Lakewood Village and Evelyn neighborhood areas, where original post-form laminate counters are still in place. Once water gets under the edge, the substrate – usually particleboard – absorbs moisture and the surface can’t be saved. A full replacement to quartz or granite is the only permanent fix.
- Tile countertops with cracked grout or lifted sections. Many mid-century Sunnyvale kitchens had ceramic tile counters installed over concrete backer. The grout lines crack over time, harbor bacteria, and are genuinely difficult to keep clean. Homeowners replacing these typically move to a quartz slab for the continuous surface.
- Pre-sale preparation in a high-comparison market. Santa Clara County buyers in the $1.5M-$2.5M range compare finishes closely. A quartz or granite upgrade before listing is one of the countertop improvements with a measurable return in this ZIP code range – and a documented photo record of the installation supports the disclosure paperwork.
- An existing slab that is cracked, stained deeply, or has a failed seam. Granite can crack if a heavy object lands on a weak seam, and unsealed granite absorbs oils and dark stains over years of cooking. If the damage is structural or covers more than a few inches, a full replacement is usually more cost-effective than a repair attempt.
- A kitchen remodel where the cabinet layout is changing. When base cabinet positions shift – adding an island, removing a peninsula, or relocating the sink – the existing countertop template is no longer valid. New slabs are templated after cabinet installation, not before.
- Countertops that don’t match a bathroom or laundry upgrade. Sunnyvale homeowners who have updated their bathrooms with quartz vanity tops frequently call us to match the surface in the kitchen. Caesarstone and Cambria both carry coordinating colors across product lines specifically for this reason.
Our Quartz & Granite Countertops Process
The sequence below is what actually happens on a Rowan countertop project – not a marketing summary. Each step produces a deliverable you can see and keep. Under the Haven Standard, no step begins until the previous one is documented and agreed to in writing.
- Written estimate before site visit. Based on your kitchen dimensions and a preliminary material selection, we produce a flat written price and written scope. This is Clause 1 of the Haven Standard: the number is on paper before anyone comes to your home. If you have a competitor’s written estimate, we’ll review it line by line at no charge – that offer stands for any homeowner in Sunnyvale.
- In-home templating visit. A uniformed, background-checked crew member templates the actual countertop footprint using digital templating equipment. We measure the substrate condition, check cabinet levelness (anything off by more than 3/16 of an inch affects the slab seam), and confirm sink cutout dimensions. The templating visit is documented with a photo record – the same standard deliverable on every Rowan visit.
- Material confirmation and slab selection. For granite, we’ll specify which slab lot the stone comes from, because granite varies by quarry run. For quartz – engineered stone made from ground quartz bound with resin – we’ll confirm the exact colorway from the product line you selected, whether that’s Cambria, Caesarstone, or another brand in our network. You know exactly what’s coming before fabrication begins.
- Fabrication and edge profiling. The slab goes to the fabrication shop where the template is cut, sink openings are routed, and edge profiles are finished. Common edge choices in Sunnyvale kitchens right now are eased (flat with a slightly softened corner), mitered waterfall edges for islands, and ogee profiles on more traditional layouts. Edge profiling affects both the look and the per-linear-foot price, and both are in your written quote before fabrication starts. Any change to the edge profile after the quote requires a signed change order – that’s not a formality, it’s how the final bill stays within a few percent of the number you agreed to.
- Installation and substrate prep. The fabricated sections are transported and installed on the cabinets. We level, shim where needed, set seams with color-matched epoxy, and secure the slab according to the manufacturer’s installation spec. For granite over 1.25-inch thickness, we verify cabinet support capacity before setting the stone – granite runs heavier than quartz at comparable thickness, and older Sunnyvale cabinetry occasionally needs a support ledger added. If that’s needed, it’s in the quote, not a surprise on installation day.
- Final documentation and 365-Day Done Right follow-up. After installation, we do a final walkthrough, photograph the finished countertops in place, and deliver the photo record along with the product warranty documentation. The 365-Day Done Right Promise covers workmanship from this point forward. If something isn’t right – a seam that opens, a chip at a cutout edge, grout that fails at a backsplash joint – we make it right. That’s printed on every page of our paperwork, not an asterisk at the bottom.

AfterQuartz & Granite Countertops Pricing in Sunnyvale
Countertop pricing in Sunnyvale reflects Silicon Valley material costs and labor rates, which run higher than national averages. The ranges below are based on current project costs in Sunnyvale and the surrounding Santa Clara County market. Your exact number will be in a written quote after templating – but these ranges give you something honest to work with before you call anyone.
| Material / Configuration | Typical Installed Range (per sq ft) | Notes |
|---|---|---|
| Entry-level quartz (standard colors) | $65 – $90 | Engineered stone, consistent patterning, low maintenance |
| Mid-range quartz (designer series) | $90 – $130 | Cambria, Caesarstone upper tiers; complex vein patterns |
| Premium quartz (large-format / book-matched) | $130 – $175 | Waterfall islands, matched vein continuity across seams |
| Entry-level granite (standard slab) | $60 – $85 | Natural stone, requires periodic sealing |
| Mid-range granite (premium quarry lots) | $85 – $130 | Exotic patterns, higher material variability slab to slab |
| Demolition and substrate repair | $300 – $900 flat | Varies by existing material (tile over concrete vs. laminate) |
| Sink cutout (undermount) | $150 – $250 each | Included in scope; complex farm sinks at higher end |
What Moves the Price Up
- Island size. A large kitchen island can add 30-50 square feet to the total footprint. Sunnyvale open-plan remodels frequently involve islands in the 12-18 square foot range, which is a meaningful cost line.
- Edge profile complexity. An eased edge costs less than a mitered waterfall. The difference is real – waterfall profiles require additional slab material and more fabrication time.
- Substrate condition. If the cabinets need leveling or a support ledger for granite weight, that work is quoted separately and shown as its own line item. You see it before we schedule installation.
- Seam count. Longer runs require more seams. Seams in quartz are more visually forgiving than in granite, where the natural stone pattern makes mismatches more visible.
- Material tier. Within quartz, the jump from a standard Caesarstone colorway to a book-matched Cambria series can be $40-$60 per square foot. Both are good materials. The difference is visual complexity and fabrication demand, not durability.

FAQs – Quartz & Granite Countertops
Is quartz or granite better for a Sunnyvale kitchen?
Quartz is the more practical choice for most Sunnyvale households with active kitchens, because engineered quartz is non-porous and doesn’t require sealing. Granite is a natural stone with unique patterning per slab, but it needs to be sealed every 1-3 years to resist oil and acid staining – olive oil, lemon juice, and wine are common culprits in a kitchen used for serious cooking. If you cook frequently and don’t want a maintenance schedule, quartz from a brand like Caesarstone or Cambria is the lower-effort option, especially when paired with updated Backsplash, Tile & Flooring. If you want the variability and look of natural stone and you’re willing to seal it, granite can be a strong choice, especially in the mid-range price tier. We walk through both options during the estimate so the written quote reflects the material you actually want, not a default. Call (650) 405-3637 to schedule a free estimate.
How long does countertop installation take in Sunnyvale?
Most countertop projects in Sunnyvale run two site visits: the templating visit and the installation visit, typically 7-14 days apart. The gap is fabrication time – after the template is cut, the slab goes to the shop for precision cutting and edge finishing. Installation itself usually takes one day for a standard kitchen. Larger projects with multiple islands, Cabinet Installation & Refacing coordination, or complex edge profiles may require two days. Your written scope will include a timeline, not a vague estimate. We photograph the completed installation before we leave, so you have a dated record of the finished work.
Do I need to remove my old countertops before you arrive?
No – countertop demolition is part of the quoted scope when it’s needed. We handle removal of existing laminate, tile, or slab material and dispose of it. If the substrate under the old counter (typically plywood or particleboard) is water-damaged, we’ll note that condition in the photo record from the templating visit and add any repair work as a written line item. Nothing gets added to the job without a signed change order. If you’re handling demo yourself to reduce cost, we’ll confirm the substrate condition on the templating visit and adjust the quote accordingly.
What warranty covers the countertops after installation?
Two separate warranties apply. The manufacturer warranty covers the material itself – Cambria offers a limited lifetime warranty on their quartz; Caesarstone offers a similar product-level warranty. Those warranty documents are delivered to you as part of the photo record and project documentation package after installation. Rowan’s 365-Day Done Right Promise covers the workmanship separately: seam integrity, cutout finishing, and substrate-to-slab fit. If a seam opens or a cutout edge chips within 365 days due to installation workmanship, we make it right – that’s printed in your paperwork, not a verbal assurance. Call (650) 405-3637 if you have questions about what’s covered before signing anything.
Why Sunnyvale Homeowners Choose Rowan Construction Group
Sunnyvale’s housing stock is dense with homes built between the 1950s and the 1990s, and a meaningful number of those kitchens are still running on original countertops. When a countertop replacement is part of a larger Kitchen Remodeling project, the documentation discipline matters more, not less – more trades involved means more opportunities for scope creep and surprise charges. The Haven Standard’s signed change-order requirement applies to every trade on the job, which is why Rowan’s projects have finished within a few percent of the agreed price across 4,000-plus projects since 2007.
Grant Rowan built that record on one operating principle: put the number in writing before anyone picks up a tool. On a countertop project, that means the written quote includes material tier, edge profile, substrate condition, cutout count, and demolition – not a range you’ll sort out later. If conditions change after templating, you see a written change order before fabrication proceeds.
Background-checked, uniformed crew. A live person answering calls at any hour. A photo record from every visit included as standard. Those aren’t upgrades here; they’re how the job runs.
If you’re ready for a written number, call (650) 405-3637. The estimate is free, the price is flat, and you’ll have it on paper before anything else happens.
