What you can hold us to
Carol's remodel sits on a horse-property lot near the Richard Nixon Presidential Library, and her island was the centerpiece of a new open plan. We bookmatched the two drops of Taj Mahal quartzite so the veining mirrors on both ends of an island with 2 waterfall sides, an estimated $2,600 to $3,500 job over an estimated 6 to 8 hours on site. Carol now has a mirrored vein pattern on both waterfall sides that greets anyone walking in from the entry.
Steve's east Yorba Linda custom home had dated granite he wanted replaced with a soft grey stone. Before quoting Sea Pearl quartzite for his 42 sq ft kitchen, we ran an acid test on a sample chip to confirm a true quartzite that will not etch, then cut and sealed the tops, an estimated $4,000 to $4,800 job that typically takes 1 to 2 days to install. Steve's kitchen passed the etch test and is sealed against Orange County's hard water spots.
Most Yorba Linda kitchens we quote are in established homes, not new tracts, and the owners usually ask for natural quartzite. That request carries a risk most buyers never hear about: some slabs sold as quartzite are really dolomite or marble, and those etch when lemon juice or vinegar sits on them. We test a chip from the actual slab lot before you commit, the same check that cleared Steve's Sea Pearl.
True quartzite typically runs $85 to $185 per sq ft installed and is sealed at install, then on a schedule. If a slab fails the test, we show you a quartzite that passes or a marble-look quartz that never needs sealing, instead of letting a soft stone go into a busy kitchen.
An open-plan remodel puts the island in the middle of every view, so its layout matters more than the perimeter runs. We lay out the island on the actual slabs at the yard, decide where the vein breaks, and cut the waterfall drops from the same lot so the stone turns the corner without a jump in pattern. Waterfall islands need a crew of 3 to 4 installers, and each mitered side is typically estimated at an added $800 to $1,800.
Yorba Linda's larger lots and its long network of horse trails mean many patios are big enough for a full outdoor kitchen, and those tops should be granite. Quartz resin can fade in direct sun, and dry Santa Ana wind seasons push grit across every exposed surface, so we set sealed granite that wipes clean. Outdoor kitchen granite tops are typically estimated at $1,400 to $2,800 per outdoor kitchen, with most installs taking an estimated 1 to 2 days once the block or steel island is built.
A Yorba Linda kitchen replacement is estimated at roughly $2,100 to $4,800 for 30 to 45 sq ft of stone, and quartzite, bookmatching and waterfall drops push a job toward the top of that range. The table lists the jobs Yorba Linda homeowners book most.
| Yorba Linda job | Est. investment | Est. time on site |
|---|---|---|
| Kitchen countertop replacement (30 to 45 sq ft) | Est. $2,100 to $4,800 per kitchen | Est. 1 to 2 days |
| Kitchen island top | Est. $1,600 to $3,400 per island top | Est. 3 to 6 hours |
| Waterfall edge drop | Est. $800 to $1,800 added per waterfall side | Est. 4 to 8 hours |
| Full-height slab backsplash | Est. $600 to $3,000 per backsplash | Est. 1 to 2 days |
| Outdoor kitchen granite tops | Est. $1,400 to $2,800 per outdoor kitchen | Est. 1 to 2 days |
Edge profiles move the price too: an eased edge is included, while half-bullnose, ogee and mitered drop edges are priced per linear foot.
Every figure here is an estimate for Yorba Linda and can change with slab availability. Your written quote after the laser template sets the final price and the install date, and it depends on the slab lot, the edge profile and how many waterfall sides you add.
Our shop sits east of Yorba Linda along the 91, so we group Orange County jobs and keep the template visit, the slab approval and install day as three planned trips. The digital laser template happens at the first site visit, before any slab is cut. Lead time is typically 1 to 3 weeks from template to install day for stock slabs, and a specialty quartzite lot can add time, which we tell you before you sign.
Beyond quartzite and exotic stone countertops, many Yorba Linda owners compare marble slab countertop installation, typically $80 to $195 per sq ft installed, with engineered quartz countertops, typically $65 to $145 per sq ft installed and never sealed. Granite still wins outdoors, where quartz resin can fade in direct sun.
Our Yorba Linda location manager covers the Orange County side, Yorba Linda, Villa Park and Chino Hills, where most jobs are quartzite and full-height backsplash work. You deal with one manager from the slab yard to the last seam, and our owner still checks seam layouts before anything is cut. Seams stay under 1/16 in. with color-matched epoxy, undermount sinks go in with clips and epoxy, and the deposit is no more than 10% or $1,000, whichever is less.
From Yorba Linda we work south into Villa Park estate kitchens, north toward Chino Hills State Park for countertops in Chino Hills, and east through the Santa Ana Canyon to Corona countertop installs. See every city on our countertop service areas page.
Remodels here often combine stone work: waterfall edge countertops for the island, a full-height slab backsplash behind the range, and outdoor kitchen BBQ countertops for the patio on larger horse-property lots.
