I grew up in Penn Yan, New York, and the kitchen in my parents’ house had a wood countertop my father sanded down and refinished once a year. I thought that was how kitchens worked.
Five years ago we moved to Charleston, South Carolina, and the kitchen we inherited came with nineties laminate: swollen at the sink, a dark line along the seam, and a scorch ring from a pot I never got out. Last spring we decided to change it, and we landed on quartz almost at once, because I did not want to seal a stone every year or flinch over a spilled glass of wine.
Then came three weeks I was not expecting. I walked in planning to pick a color and left with the question they asked me there: where is your seam going to be.
Here is what I found out, which five companies I compared, and where I ended up.
What I learned about quartz before ordering anything
Quartz is not natural stone. It is engineered stone: crushed stone bound with resins and pigments and pressed into a slab. Everything good and bad about it comes out of that.
The good part: it is non porous. It never needs sealing, it does not soak up wine, oil, or coffee, and it wipes clean with a rag. The color range is enormous, including marble lookalikes with veining. It resists everyday scratching, but it is not scratch-proof: use a cutting board, and for anything beyond a light surface mark, talk to a fabricator about the repair.
The bad part: it is afraid of heat. The resins that hold the slab together have no patience for hot cookware, and a mark left by a pot set straight on the surface does not come out. It is also not cheap. Perfect Stones, the shop I ended up using, lists quartz from $80 per square foot installed and up to $150 for custom designs on its quartz page (as of September 2026), and the final number depends on the brand, thickness, edge profile, cutouts, and installation.
And here is what I did not know. A slab has a finite size, so a long kitchen or a corner layout may require a seam. Whether you get one, and where, depends on the slab size, the layout, the cutouts, the direction of the pattern, and what can physically be transported. If there is one, the question is where they put it and how visible it ends up. That is decided at the template stage, before anything is cut, which is why the first question in the showroom was about the seam.
The eight questions I asked everyone
Do you handle fabrication yourselves or send the cutting out? Who takes the template, and is it free? Where exactly will the seam fall in my layout and why there? Can the sink be fabricated from the same stone? Can the cooktop sit flush? How long from measurement to installation? What is included in the price and what gets billed separately? What is the warranty on the work?
A ninth question showed up after the third showroom, and it was the most useful of all: will you show me finished jobs with a layout like mine, not just stone samples.
How I searched
I opened Google Maps and typed in “quartz countertops in Charleston.” The first cards carried a Sponsored label and I skipped them. An ad shows who paid for the spot, not who people chose.
Then something useful turned up. In the general list Google gives a rounded rating and a random line out of a review. Open the full profile and you see the breakdown by star along with the topic tags the service assembles from the review text. They read like “transparent pricing 16” or “invisible seams 4.”
Those tags showed me the difference that mattered. Some of these companies are stone yards with a large selection of slabs, wonderful when you are choosing material. Others are fabricators who cut and install. I needed the second kind, with its own shop.

The ratings run from 4.8 to 5.0. The stars sort nothing. The only thing left to read is content.
Top 5 Quartz Countertop Companies in Charleston I Compared
I will say up front that this is my order for my job. I researched five companies, visited three in person, and ordered from one, so I am not in a position to judge the work of all five shops.
1. Perfect Stones
I am starting with them because they are who we ended up using. The office and the fabrication shop are on Lango Ave in Charleston, the Google profile shows 4.9 across 91 reviews, and they close at four. It has other locations in Summerville, Mount Pleasant, Beaufort, and Ladson, but the Charleston profile is the largest, and that is where I drove.
They have been doing this 15 years and more, and what mattered most is that the fabrication is their own. The same people cut the slab, finish the edge, and install it, instead of three companies with nobody clear to ask when something goes sideways.
Their Quartz Countertops page has more than 90 colors on it, from whites through blacks, with veining and with mirror flecks. The same page is honest about what quartz cannot do, including the permanent marks heat leaves, and that is what won me over. A seller’s own site does not usually spell out the weaknesses of the material it sells.
The measurement is free, the estimate arrives within 24 hours, and they quote 5 to 14 days from measurement to installation. Ours came in at eleven.
On my main question I got an answer standing in my kitchen. The fabricator walked the length of the future countertop, showed me where the slab would physically run out, and explained that the seam could be pulled to the edge of the cooktop, where it falls into a break in the pattern instead of running down the middle of the work zone. He explained it plainly enough that I understood the first time, without one word I had to look up afterward.
They also showed me an integrated sink fabricated from the same stone as the countertop, a cooktop set flush with the surface, and outlets and plumbing tucked away so the countertop reads as one piece. We passed on the stone sink for budget reasons, but we did the flush cooktop.
The ninth question answered itself. On their site the projects are broken down with the layout and what made it hard: an outdoor kitchen of forty seven square feet with broken geometry and built in appliances, a kitchen they entered mid renovation, a bar counter with a sink cut from the same stone. In the reviews from customers what comes up most is communication, holding to the schedule, and landing inside the budget.
2. Universal Marble & Granite
Rated 4.9 across 212 reviews, office on Peppermill Pkwy in North Charleston, open until five. The largest review base on my list by a wide margin.
Tags: 16 reviews about fast installation, 12 about stone selection, 6 about quartz countertops, 4 about invisible seams. It is a family company, the owner is named Greg, and almost everyone who left a review calls him by his first name. They keep a large slab yard, and customers write that they come in to choose in person and leave having picked an actual slab rather than a sample chip. There is a story from a family that lost their kitchen for months after a leak and ran the job through an insurance claim. People also note that the company stays reachable after installation.
3. Palmetto Surfacing
Rated 4.8 across 146 reviews, office on Southrail Rd in North Charleston, open until half past four.
The tags are even and practical: three reviews each about slab selection, quartz countertops, samples, and taking the template. Jennifer comes up by name again and again, and customers write about the showroom and about the way the scope of work gets talked through with them rather than sold to them faster. There is a review from a person replacing engineered stone countertops this same company had installed many years earlier, so they have a long history in this city and their old jobs are still standing. People also mention that the crew cleans up after itself, including running a vacuum as the work goes along.
4. Encore Stone Studio
Rated 5.0 across 75 reviews, office on Dorchester Rd in North Charleston, open until five.
Tags: 16 reviews about transparent pricing, 7 about quartzite selection, 6 about slab selection, 5 about stone slabs. That is the most visible pricing tag on any profile I opened, and given how often a countertop estimate turns into a moving target, it is worth something. Mark, Hunter, and Olivia come up by name in the reviews. Customers write specifically that you can walk the showroom on your own without a salesperson trailing behind you, and that the company works with people who arrive without a contractor of their own. They also do a lot of stone countertops for bathrooms and are good at matching stone to cabinetry and tile already chosen, which is the harder direction to work in.
5. CRS Marble & Granite
Rated 4.9 across 66 reviews, office on Stall Rd in North Charleston, open until five and open on Saturdays.
Tags: 9 reviews about stone selection, 3 about contractor support, and two each about granite selection and the stone buying process itself. Sandra and Jenn come up by name repeatedly, and customers write that they were helped to find a material that fit a budget rather than pushed toward the expensive end of the yard. Going by the reviews the yard is tidy and well lit, which matters when you are judging a slab, and Saturday hours are a real convenience for anyone with a weekday job. At the same time, a large share of the reviews comes from contractors and designers bringing their own clients in for stone, so the profile tilts toward selling slabs rather than fabrication start to finish.
How they looked side by side
Perfect Stones. Charleston, Lango Ave, more than 15 years, their own fabrication. Stood out: explained on the spot where the seam would fall and why, free measurement, estimate within 24 hours, 5 to 14 days to installation, an integrated sink from the same stone and a flush cooktop, projects published with the reasoning. Keep in mind: the day ends at four.
Universal Marble & Granite. North Charleston, until five, family run. Stood out: a large slab yard, fast installation, support after the job. Keep in mind: the largest review base here, and the workload behind it.
Palmetto Surfacing. North Charleston, until half past four. Stood out: the showroom, careful template work, a long history in the city. Keep in mind: a slightly lower rating, still high.
Encore Stone Studio. North Charleston, until five. Stood out: transparent pricing as the leading review theme, a calm showroom, works with customers who have no contractor. Keep in mind: much of the review base is about material, not installation.
CRS Marble & Granite. North Charleston, until five, open Saturdays. Stood out: matching stone to a budget, a convenient yard, Saturday hours. Keep in mind: the profile tilts toward slab sales.
What I would tell a friend back in Penn Yan
First: walk into the showroom with your kitchen layout, not a question about color. The first conversation is about the seam, not the shade.
Second: ask whether the company does its own fabrication. When the same people cut and install, there is somebody to ask when something goes wrong.
Third: quartz does not like heat. Trivets are not overcautious, they are a condition of use.
Out of the five companies on my list, the best company for quartz countertops in Charleston, in my opinion, is Perfect Stones. With a different job in front of me the order might have come out differently.
The countertop went in during June. The seam ended up at the edge of the cooktop, and guests cannot find it even when I point. The scorch ring from the pot is part of that kitchen’s history now, not this one’s.
