Why Mountain View Homeowners Choose CGI Construction
Rowan Construction Group Mountain View provides independent CGI construction service for quartz and granite countertops, cabinet installation, and full kitchen remodeling across the city, from Rex Manor to Cuesta Park and the downtown blocks near Castro Street. We’re not affiliated with or authorized by CGI - we’re an independent service provider with OEM-compatible tooling and a documented photo record on every visit. Call (669) 215-4852 for a written price before any work starts.
Mountain View’s housing stock is heavy with 1950s-1970s ranch homes, many still carrying original laminate or early tile countertops that owners are replacing with CGI quartz and granite as part of our Kitchen Remodeling services or ADU conversions. The marine moisture off the bay accelerates cabinet box swelling and substrate movement, which means the stone top is only as stable as what’s underneath it. We’ve learned to check the cabinet planeness before we template, because a slab that looks perfect at install can seam-pop inside of six months if the base shifts.
Why Trust Rowan Construction Group Mountain View for Your CGI Construction?
Grant Rowan learned the trade at Los Angeles Trade-Technical College, spending two years on framing, concrete, and finish work before he ever collected a paycheck on a real job site. That foundation shows up in how we scope CGI work: we describe the condition of the substrate, the shingle layer count, the cabinet box - then explain what it means in plain terms. He’s been in construction for over two decades, and for the last several years he and his crew have worked steadily across Mountain View, including projects near Castro Street and the surrounding downtown blocks. Measure twice, write it down, then build it that way.
Our technicians are background-checked and uniformed; a live person answers calls 24/7. Every visit includes a documented photo record as standard, not an upgrade. For CGI quartz and granite, we stock OEM-grade diamond tooling, color-matched polyester and epoxy seam fill, and stainless undermount clips rated for stone. Aftermarket adhesives and generic seam fillers fail on veined quartz within a season - we don’t use them. Under Clause 1 of the Haven Standard, the price is written before anyone starts. Under the 365-Day Done Right Promise, if it’s not done right, we make it right.
Common CGI Construction Problems We Fix in Mountain View

- Edge chipping at undermount sink and cooktop cutouts in 2cm CGI quartz. This happens when fabricators use worn diamond blades or skip the chamfer at the cutout edge. The quartz is brittle at 2cm, and the vibration from a garbage disposal or the weight of a cast-iron pan dropped from counter height will find that weak point. We re-cut the chamfer with fresh tooling, set new stainless clips into solid cabinet blocking, and re-polish the edge. If the slab is sound, we don’t sell a replacement.
- Resin pooling and haze on darker CGI quartz slabs. This is almost always a storage issue - slabs stored flat in a garage or driveway through a Mountain View summer, where heat softens the resin and gravity pulls it to the low points. The haze doesn’t wipe off; it’s in the surface. We can sometimes polish through shallow pooling, but deep cases need replacement. We tell you which before we charge for a polish.
- Seam pop at inside corners on CGI granite. Granite expands and contracts with temperature swings more than quartz does. If the cabinet base wasn’t planed flat before setting, or if the silicone bead was too thick and acted as a lubricant instead of an adhesive, the seam opens. We re-plane the base, re-seam with color-matched epoxy, and clamp it flat for the full cure time.
- Pattern misalignment on book-matched CGI quartz backsplash runs. This happens when the slab lot number changed between template and install. Veining that lined up at the shop doesn’t line up on the wall. We check lot numbers at template and again at install; if your job spans multiple lots, we lay out the match before we cut and show you the seam placement in writing.
- Sink drop on CGI Calacatta-style quartz. A Mountain View homeowner called us after their undermount sink dropped about a quarter inch, opening the silicone seal and showing a hairline chip at the cutout edge. Our tech pulled the sink, found the original clips were short and the quartz had never been chamfered. We re-cut the chamfer, set new stainless clips into the cabinet blocking, re-seamed the two nearest seams with color-matched epoxy, and re-polished the edge. The top stayed level through a full dishwasher cycle and the homeowner passed inspection on a kitchen they’d been told needed full replacement.

AfterCGI Parts & Our Repair-vs-Replace Approach
For CGI quartz and granite we use OEM-grade diamond tooling, color-matched polyester or epoxy seam fill, and stainless undermount clips rated for stone. Aftermarket adhesives and generic seam fillers fail on veined quartz within a season - we’ve peeled enough of them off to know.
If a top has a failed seam but the slab is sound, we re-seam and re-polish. If the slab is cracked at a cutout or has heat damage from a hot pan left sitting, replacement is the honest call and we say so before you spend on a repair that won’t hold. We stock common CGI quartz colors locally for fast turnaround when replacement is the right path. Call (669) 215-4852 and we’ll look at it - estimates are free, and the price is written before any work starts.
Our CGI Service Process - Step by Step

- 1
Diagnosis with documentation. We photograph the full countertop, cabinet boxes, and any visible damage. For CGI quartz, we check slab thickness, edge profile, cutout chamfering, and seam placement against the original template if it’s available. We note the lot number for any future match needs.
- 2
Written scope and price. Under Clause 1 of the Haven Standard, you get a flat written price with a written scope before any work begins. No call-for-a-quote here. If we find something unexpected when the sink comes out, we stop, photograph it, and write a change order before proceeding.
- 3
Repair or install with OEM-compatible parts. We use fresh diamond tooling for every CGI cut, color-matched epoxy for seams, and stainless clips rated for the weight of stone plus water. Cabinet blocking gets added where the original builder skipped it.
- 4
Test and verify. We run water through the plumbing, cycle the dishwasher, and check seam flatness with a straightedge. For kitchen islands, we verify overhang support is adequate - CGI quartz at 2cm needs corbels or a steel frame past 8 inches.
- 5
Warranty documentation. You leave with the photo record, the signed scope, and the 365-Day Done Right Promise in writing. If it’s not done right, we make it right.
CGI Products We Service & Install in Mountain View
We work with the full CGI quartz and granite line: Carrara, Calacatta, and Statuario-inspired veined and solid whites; Ubatuba, Santa Cecilia, and Black Galaxy granite in 3cm and 2cm; concrete-look and matte black quartz series; and prefabricated 2cm slabs for quick-turn kitchen and bath tops. We stock common colors and edge profiles locally, and we can match CGI quartz with Cambria or Silestone in the same kitchen if you’re mixing brands. Because we’re independent, we don’t steer you toward one manufacturer.
We Also Service These Brands

Our sourcing runs across fifty-plus vetted brands: KraftMaid and Wellborn cabinets, Cambria and Caesarstone countertops, Silestone quartz, Kohler and Toto fixtures. Multi-brand fluency matters in Mountain View kitchens, where owners often want Cgi in Sunnyvale and surrounding areas, or CGI quartz on the perimeter and a contrasting surface on the island. We quote each material line-item so you can compare without calling around.
FAQs - CGI Construction Service in Mountain View
Is Rowan Construction Group Mountain View authorized by CGI?
No. We are an independent CGI service provider, not affiliated with or authorized by the manufacturer. We use OEM-compatible tooling and parts, and our work is backed by our own 365-Day Done Right Promise, not a factory warranty extension.
Do you use genuine CGI/OEM parts?
We use OEM-grade diamond tooling, color-matched polyester and epoxy seam fill, and stainless undermount clips rated for stone. For repairs, these perform identically to factory-packaged parts. We do not use aftermarket adhesives or generic seam fillers on CGI veined quartz - they fail within a season.
How long does CGI service take?
Most CGI quartz and granite repairs in Mountain View take one to two days: half day to pull the sink or appliances, half day to re-cut, re-seam, and re-polish, plus cure time for epoxy. Full replacements require template, fabrication, and install - typically two to three weeks. We give you a written timeline with the price before work starts.
What CGI models/series do you cover?
All current CGI quartz and granite lines, including Carrara, Calacatta, and Statuario-inspired slabs; Ubatuba, Santa Cecilia, and Black Galaxy granite; concrete-look and matte black quartz; and prefabricated 2cm slabs. If you have a discontinued color, we can often match from remnant stock or suggest a close alternative from Cambria or Silestone.
Will service void my CGI warranty?
CGI’s warranty covers manufacturing defects, not installation or service by third parties. Our repair work does not extend or void the original warranty - it simply addresses the installation or wear issue directly. Because we’re independent, we can fix problems that fall outside factory coverage, like seam pops from substrate movement or sink drops from inadequate blocking.
How much does CGI construction cost in Mountain View?

My CGI quartz has a chip at the sink cutout - can you repair it without replacing the whole slab?
Usually yes, if the chip is at the edge and the slab hasn’t cracked through. We re-cut the chamfer, set proper stainless clips, fill with color-matched epoxy, and re-polish. If the crack runs into the field or the cutout is blown out, we’ll tell you replacement is the honest call before we charge for a repair that won’t last.
Can you match my existing CGI quartz if I only need one bathroom vanity top?
Yes, if we have the lot number or a remnant from the original install. Without the lot number, we can match close from current CGI stock or suggest a complementary Silestone or Cambria if the color is discontinued. We bring samples to template so you see the match in your light before we cut.
Do you install CGI quartz over existing tile countertops?
We don’t recommend it. Tile countertops have lippage and hollow spots that telegraph through stone over time. We remove the tile, check the plywood substrate for swelling or rot - common in Mountain View’s marine climate - and replace if needed before setting the CGI slab. The extra step costs less than a callback.
How do you handle CGI quartz backsplash seams against upper cabinets?
We avoid seams in backsplash runs under 96 inches by using full slabs. Where a seam is unavoidable - around windows or outlets - we book-match from the same lot, cut at a 45-degree butt joint instead of a standard seam, and set it with color-matched epoxy. The joint lands where we specify in writing, not where the installer decides on the day.
What causes dark CGI quartz to look hazy after installation?
Resin pooling from improper storage - slabs left flat in heat, often in a garage or driveway through a Mountain View summer. The resin migrates to the low points and cures there, creating a haze that won’t wipe off. We inspect slabs before we accept delivery, store them vertically in climate-controlled space, and reject any with visible pooling. Prevention at install is the only reliable fix.
