Quartz vs. Granite Countertops

Quartz and granite are the two materials most Vancouver homeowners end up choosing between, and they are closer in performance than the showroom arguments suggest. Both are hard, both last, and both sit in the middle to upper part of the countertop price range. The real differences are heat, sunlight, sealing and how much the finished counter will look like the sample. The countertop overview covers the whole field; this page is the head-to-head.

What each one is

Quartz is a manufactured slab, also called engineered stone. Ground quartz and other minerals are mixed with pigments and a resin binder, pressed and cured. The mineral gives it hardness. The resin makes it non-porous and is also the source of its two weaknesses, heat and sunlight.

Granite is quarried rock, cut into slabs and polished. In the trade the word covers more than a geologist would allow. The Natural Stone Institute notes that most igneous rocks, including gabbro and basalt, are grouped commercially with granite because they perform similarly, and that some stones sold as granite are really gneiss or gabbro. That is not a trick. It does mean two "granites" can differ in density and porosity, so judge the slab, not the label.

Side by side

Heat

This is the clearest difference. Granite formed under heat and is not bothered by a pan off the burner. Quartz is held together with resin, and resin does not like sudden high heat. A hot pot can leave a dull or yellowed ring, and a slow cooker or air fryer run for hours in one spot can do the same. The damage is in the binder and cannot be polished out the way a mark on stone sometimes can.

The Natural Stone Institute recommends trivets or mats even on natural stone, so the habit is the same for both. The difference is what happens the one time you forget.

Stains and sealing

Quartz does not absorb liquids, so it never needs a sealer. It is not stain-proof. Dyes, permanent marker and some cleaners can mark the resin, which our article does quartz stain covers in detail.

Granite is where most of the confusion sits. The Natural Stone Institute states that most granite countertops do not need to be sealed, and that in many cases it still makes sense to apply a quality sealer for added resistance to everyday spills. It also explains what a sealer is: stone sealers are impregnators that act as a repellent, and they make the stone more stain resistant, not stain proof. Many slabs are treated with resin at the factory, which fills small pores before the slab is ever sold.

A simple check on a sample: leave a few drops of water and a few drops of cooking oil on the surface for ten to fifteen minutes and wipe them off. If the stone darkens where the drops sat, it is absorbing and should be sealed. If nothing changes, it is dense enough that sealer adds little.

Scratches and chips

Hardness is close to a tie. On the Mohs scale as published by the National Park Service, quartz is 7, feldspar is 6 and a knife blade is about 5.5. Granite is made largely of feldspar and quartz, and engineered quartz is mostly ground quartz, so a kitchen knife will not readily scratch either one. It will dull the knife, so use a cutting board.

Chips are a different matter from scratches. Both materials chip at edges and around undermount sinks when hit by a heavy pot. The edge profile has more influence on chipping than the material does, which is covered in countertop finishes, edges and thickness.

Pattern, seams and choosing a slab

With quartz you choose from a sample and the slab that arrives matches it. That makes it easy to plan a kitchen on paper and easy to add a matching piece later if the color is still made. Plain whites and fine-grained colors hide seams well. Quartz with bold printed veining is harder: the veins will not line up across a seam unless the fabricator plans for it.

With granite you choose the actual slabs at a stone yard, and they are tagged for your job. Two slabs from the same block can be laid out so the pattern flows across a seam. Ask the fabricator for a layout showing where each counter section will be cut from the slab. This is the step that separates a good granite kitchen from a disappointing one.

Sunlight and outdoor use

Resin can shift color with long exposure to ultraviolet light. Indoors, that matters where a counter sits under a south-facing or west-facing window or beside a large patio door: the exposed section can drift from the shaded section over the years. Granite does not have this problem and is the usual choice for an outdoor kitchen or a covered patio counter.

Cost and resale

The two overlap. Common granites and plain quartz colors sit in the mid tier. Rare granites and quartz with large-scale veining sit higher. The slab is only part of the bill: cutouts, edge profile, the number of seams and whether the backsplash is slab all move the total. In JDI Construction's published planning ranges, a quartz or stone slab backsplash is a $3,000-$8,000 add-on, and the whole-kitchen ranges are on the kitchen remodel cost page.

For resale, both read as a quality stone counter to buyers. A neutral color that suits the cabinets matters more than which of the two it is. A loud granite chosen to your taste can date a kitchen faster than a quiet one, and the same is true of a quartz pattern that follows a passing fashion.

What to check before you buy

• Granite: view and tag the actual slabs, in daylight if the yard allows it.
• Granite: ask whether the slab was resin-treated and what sealer the fabricator applies.
• Granite: run a fingernail over the surface for pits and fissures, and ask which are natural and which were filled.
• Quartz: read the care and warranty document for the heat and sunlight exclusions before you commit.
• Quartz: ask for the slab size, and whether your island can be cut from one slab.
• Both: ask for a seam layout drawing and approve it.
• Both: take a sample home and look at it beside your cabinet door in your own light.

Who should choose which

Choose quartz if you want a clean, uniform look, especially a white or soft gray; you will not think about sealing; you are planning the kitchen from samples; or the counter must match across several separate sections.

Choose granite if you cook hard and set pans down without thinking; the counter gets strong direct sun; you want natural variation no one else has; or the project includes an outdoor counter.

Look further if you want the veined look of marble. Then the comparison to read is quartz versus quartzite, or porcelain and sintered stone if heat and sun both matter. Our longer article on the types of countertops covers the remaining materials.

JDI Construction handles countertop selection during design, alongside the cabinets and backsplash, so the three are chosen together. To talk through options for your own layout, start at our Vancouver kitchen remodeling page.
