Natural Stone
Considering Quartz Countertops?
But a few things trip people up. Let's clear them up.
"Do I ever have to seal it?"
✓ Never.
Quartz is non-porous, so there's nothing to seal and most spills wipe right off. It's stain-resistant, not stain-proof, so wipe up wine, coffee, and turmeric before they sit, and skip bleach and harsh cleaners that can dull the finish.
"Can I set a hot pan on it?"
✓ Yes, With a Trivet.
Warm dishes are fine. But a pan straight off a screaming burner, or an air fryer venting onto the slab, can scorch the resin or crack the slab outright. Keep a trivet close for anything hot off the stove. Cooking on high heat all day? Ask us about granite or quartzite.
"Will the seams look obvious?"
✓ You Approve the Layout First.
Pronounced patterns can jump at a badly placed seam. So we lay your counters onto a digital copy of the actual slab you picked. You see exactly what you'll get, seams and all, before we cut a thing.

What Our Customers Say
Quartz Installations We're Proud Of
"One particularly useful and fun tool Granite Guy offers is the ability for the homeowner to view the design and layout of the counter on computer software and to be part of the esthetic decisions as to which part of the slab would look the best in our space, and where any seams (if needed) should be placed."
Alissa JarvisVerified Google Review
"We were able to visit without appointments to see their selections and even got a remnant for our bathroom that saved us some money. They were able to provide samples for us to take home to check color schemes in our lighting and with other decor."
Kerry BellefontaineVerified Google Review
"We were never left wondering when our quartz was going to come and they even special ordered a piece for us they didn't have in stock. This is a vendor who will give a damn about you and isn't there to just take money and leave."

Pricing
How Much Do Quartz Countertops Cost?
Pricing matters. It's the first question everybody asks, and we get it.
But there's no price list in this business. The same color can cost very different money from two different brands, and the work you want done changes the rest of it.
Quartz is priced by the square foot, like any counter. About 95% of materials fall between $55 and $150 per square foot installed, and quartz sits inside that range. Solid colors are typically the least expensive, and the bold, realistic marble looks usually cost the most.
But it's not just about material. Here's what else affects your price:
-
Sourcing: From in-stock inventory, you pay a set price per square foot for what you use. Special orders come by the whole slab, the only way the industry sells them. We keep remnants for small projects too.
-
Project size: Bigger projects cost more than smaller ones, but often get better per-square-foot pricing.
-
Complexity: A waterfall means a mitered corner and more fabrication. A long overhang may need support underneath. An integrated sink adds work. Each one adds cost.
-
Waste: Intricate shapes and matching the veining piece to piece mean more of the slab goes unused. We lay out every cut digitally to get the most usable countertop from each slab, but on a heavily veined color, the pattern still decides how much we can save.
-
Supply and demand: The most realistic marble looks carry a premium because demand is high, and the brands know it.
So How Do You Budget?
Somebody asks what Calacatta quartz costs and there's no honest answer. One brand alone can have half a dozen Calacattas, and every brand has its own. Ask exactly which brand and which color, because what you pay for the name usually buys better quality and a better warranty.

How Does Quartz Compare?
Weighing quartz against the alternatives? Here's the honest rundown on each.
| Material | The honest read | Full comparison |

| Granite | Quartz for a consistent marble look and no sealing; granite for heat tolerance and outdoor use. | Quartz vs Granite → |
| Marble | Quartz for the marble look that won't etch or stain; marble for the real thing, if you'll baby it. | Quartz vs Quartz → |
| Soapstone | Quartz for bright whites and a huge color range; soapstone for a warm, matte look that takes heat. | Quartz vs Soapstone → |
| Porcelain | Quartz for depth and pattern in a thicker slab; porcelain for UV-proof outdoor use and heat resistance. | Quartz vs Porcelain → |
Maintenance
Living With Quartz
It's stain-resistant, not stain-proof, so wipe up wine, coffee, and turmeric before they sit. And keep a trivet handy: high heat can scorch the resin or crack the slab.
Honest Assessment

Cons
-
!
Extreme heat is the weak spot: it takes a lot, but a pan straight off the burner can scorch the resin or crack the slab, so keep a trivet close
-
!
Indoors only: UV will yellow and fade it, so outdoor kitchens need granite or porcelain
-
!
Too many options: dozens of brands and hundreds of colors, with near-identical looks and names priced very differently from one brand to the next
