Granite is a real igneous stone, not an engineered surface. You pick your slab off our Austin floor, then our crew templates, fabricates and installs it.
Granite countertops are cut from a natural igneous rock that formed when magma cooled slowly underground. That slow cooling is what gives granite its visible grain of interlocking mineral crystals, mostly quartz and feldspar with smaller amounts of mica and amphibole. On a slab floor the variation hits you immediately. No two slabs are the same, even when they come from the same quarry and carry the same trade name. Some are calm with small, even flecks. Others have sweeping movement, veins, or tight clusters of darker minerals that read as bold pattern. Because it is natural stone, expecting perfect consistency across a kitchen is a mistake. A sample chip only shows a tiny piece of a much larger slab, so the full slab is where the real decisions happen.
Hardness and heat tolerance are the two things people bring up first, and they are mostly right. On the Mohs scale granite usually lands around six or seven, which means a steel knife will not scratch it in normal use. You can set a hot pan straight off the cooktop onto granite without scorching or cracking the stone itself. The weak point is not the stone. It is the sealer and any resin fill at fissures. High heat can discolor some sealers over time, so using a trivet is still the safer habit. Granite is porous, though not as porous as marble. Spills left sitting, especially oil, wine, or coffee, can soak in and leave a shadow if the sealer is worn. That brings up the one chore: periodic sealing.
Getting granite in Austin through our setup means you walk our slab floor off Metric Boulevard and tag the exact slab you want. You do not pick from a catalog or a sample and hope for the best. After slab selection we schedule the template, which is a digital measure of your cabinets. Fabrication is done in our shop, and the same crew handles the install including sink cutout and sink set. The slab floor stocks around 299 lots, pulling from a direct importer, so the stone has not bounced through multiple middlemen before it gets to you.
Granite handles hot pans better than quartz. The stone itself does not burn or melt. Practice says use a trivet anyway, because repeated high heat can age the sealer.
Granite is porous. Sealer blocks most staining but wears with use. Water beading tells you it is working. When water stops beading, reseal. It is not hard, but it is not a zero maintenance surface either.
Granite is not uniform. Color, veining, and crystal size shift across the slab and between slabs. Seeing the full slab before fabrication is the only way to know what your counters will actually look like.
Geologically, granite is a plutonic igneous rock. That means it formed from magma that intruded into older rock and cooled slowly enough for visible crystals to grow. The dominant minerals are quartz, which is hard and stable, and feldspar, which gives the stone its base tones of white, gray, pink, or beige depending on the potassium or plagioclase ratio. Smaller amounts of biotite mica, hornblende, or augite speckle the slab with dark grains. The overall look is granular and crystalline, even on slabs that carry dramatic bands or movement. The difference between a busy slab and a quiet one is not a different rock type. It comes from the cooling history and the mineral soup that the magma started with.
In the countertop trade, granite is often stretched as a label. Some stones sold as granite are technically granodiorite, gabbro, or even syenite. They all share enough working properties to be treated the same way. Hard, polishable, and heavier than engineered sheets. A three centimeter slab of granite weighs roughly eighteen to twenty two pounds per square foot. That weight is why cabinet reinforcement or at least a solid substrate matters on a large island. For most American face frame cabinets, standard construction holds the load fine as long as spans are not excessive.
Stone color and porosity both tie back to mineral content and the amount of microfracturing inside the rock. Darker granites, often called black granite even when they are gabbro, tend to be denser and absorb less liquid. Light granites with more feldspar and quartz are typically more absorbent. A lemon juice test on a raw offcut tells you something, but most slabs arrive with a factory seal already applied. That factory seal does not last forever. It buys you time to settle in before you do your own sealing.
Polished granite is the default. The face is ground with fine abrasives until it reflects light and the color deepens. That gloss also closes the surface pores to some degree, giving a polished slab a head start on stain resistance. The tradeoff is that polished granite shows fingerprints, water spots, and smears faster than a matte finish. On a dark slab, polished shows every streak. On a busy slab with active movement, polished can also create glare highlights that compete with the pattern.
Honed or leathered finishes are gaining ground. Honed granite is ground flat but not buffed to a high shine. It has a soft, low luster that hides scratches and etching better, though granite rarely etches the way marble does. The downside is the open pores. Honing exposes more pore space at the surface, so a honed slab often wants sealing more frequently. Leathered granite, also called brushed, is a textured finish that retains some of the stone’s natural cleft. It hides smudges and water marks extremely well and feels warmer to the hand. Leathering is not available on every slab type. It works best on stones with enough hardness to hold the texture without crumbling.
Edge profiles are separate from the face finish but influence how a countertop reads in the room. Eased edge, quarter round, half bullnose, full bullnose, and ogee are common. Eased is the simplest and keeps a modern slab look. Ogee and full bullnose add visual weight and catch light differently, which can shift how thick the stone appears at the front edge. For granite, the edge is cut and polished by the fabricator to match the face finish. It is not an add on piece. It is the same stone, so the vein or grain wraps over the edge continuously when the slab has enough pattern to show it.
Slab selection is the step that separates custom countertops from stock order jobs. You come to our slab floor in Austin. The floor holds roughly 299 lots at a time, organized by material and color family. Granite bundles sit alongside quartzite, marble, and porcelain. Each bundle usually has two to six slabs from the same block, cut sequentially. Sequential slabs share the same overall look but differ in detail. For a long island or a counter run that requires multiple slabs, picking slabs from the same bundle keeps the flow consistent. Bookmatching is possible when the fabricator opens two sequential slabs like pages of a book to mirror the vein. We can arrange that on request.
When you walk the floor, we pull the slabs you want to see upright on the A frame so you can view them in natural and shop light. You look at the overall movement, note any natural fissures or mineral pockets, and decide if the scale of the pattern works for your cabinet layout. A slab with a big bold vein might look incredible on an island but overpower a narrow perimeter run. Measuring the slab ahead of your choice is part of the process. We confirm the slab size against your rough cabinet dimensions before you commit, so you are not buying stone that cannot yield the needed pieces.
Once the slab is tagged and your cabinet run is measured with a digital template, the fabricator nests the parts onto your slab. Nesting is the puzzle of fitting sink cutouts, seams, and edge return pieces into the slab rectangle. A good nest uses the stone efficiently and puts the best figure in the most visible areas. The seam location is decided during templating, not on install day. Seams in granite are filled with color matched epoxy and polished flat. They never vanish completely. They become a tight line that you see when you look for it, which is honest for real stone.
Granite’s strong suits are heat tolerance, scratch resistance, and the fact that no sheet looks like another. The heat tolerance is real. A pan from a five hundred degree oven can land on granite without cracking the stone. The scratch resistance is generally real for kitchen knives, though a diamond ring will mark it. What granite is not is stain proof, acid proof, or chip proof. Dark juices, greasy drips, and cooking oil can penetrate if you let the sealer wear thin. Little chips at the front edge happen when a heavy pot corners the stone just wrong. Those chips can be filled and polished by a stone pro, but it is a repair call, not a wipe down.
Compared to quartz, granite demands the sealer habit. Quartz is non porous and needs no sealing, but quartz resins turn brown or brittle under sustained heat and UV. So granite wins on heat, quartz wins on stain resistance without upkeep. Compared to marble, granite does not etch from lemon juice or vinegar. Marble loses its polish in a dull spot when acid hits it. Granite stays glossy. This is the practical reason kitchens lean granite and bathrooms lean marble. The kitchen sees acid, heat, and dragging pans daily.
Compared to quartzite, the line can blur. Hard quartzite is generally harder than granite, but some slabs labeled quartzite are actually dolomitic marble or a mixed stone. They will etch. Our floor separates the bundles straight. When you ask to see granite, you are looking at igneous stone that will not etch. When you ask quartzite, we walk you through the hardness and acid test so you know exactly what you are buying.
The first move is contacting us to set a time to walk the slabs. We are reachable seven days a week at (512) 297-7493 or info@atxgraniteking.com. You do not need to bring cabinet drawings to the first slab visit, though having approximate measurements helps us guide you toward slabs with enough material. The formal template happens later, after the slab is tagged and your cabinets are installed and level. Cabinets need to be set and leveled to your finished floor before templating. If cabinets are not in yet, we wait.
After the template, the crew gives you a quote in writing with dates. That document spells out the slab you chose, the edge, the finish, the number of seams, sink cutout and set included, and the schedule from fabrication start through install. The sink cutout is done at the shop on the CNC or with a rail saw, and the sink is set and siliconed during install. We install the sink. The plumber hooks up the drain and faucet later. Seam location, overhang, and backsplash height are all locked in the quote.
Service area runs Austin proper and the I 35 corridor: Pflugerville, Round Rock, Cedar Park, Leander, Georgetown, Hutto, Jarrell, Salado, Belton, Temple, Killeen, and Harker Heights. For rental grade or flip grade stone we coordinate with a slab selection and fabrication partner that stocks budget friendly options. That path keeps the same start to finish crew model but pulls from a different slab set so a rental does not carry the cost of a showpiece slab. If you need a number to make a decision, call for a straight quote. We walk you through every line item over the phone or in person, no vague ranges.
$38 per square foot, cut, measure, and install included. Jobs over 1,000 square feet: $30 per square foot.
Sink cutout and sink set are included in the fabrication work. Non standard work is still quoted before work begins. Send the rough square footage and the rooms involved, or call (512) 297-7493 for a straight quote.
Not instantly, but eventually yes. Granite is porous, and the sealer buys time by slowing absorption, not by making the stone plastic. If you cook with oils, red sauces, or coffee daily and never reseal, dark spots can form and become permanent. The test is simple: drip water on the surface and watch. If it beads, the sealer is working. If it wets out and soaks in within a few minutes, it is time to reseal. Resealing is a wipe on, sit, wipe off job that takes an hour of attention every year or two, depending on the slab color and use.
The stone itself generally survives without cracking, and you are unlikely to scorch the granite. The risk sits with the sealer and any resin fill near natural fissures. Sustained high heat can discolor some sealers or soften resin fills, which then collect dirt and look different from the surrounding stone. A simple trivet or folded dry towel removes the risk entirely, so most people just keep that habit even on granite.
That depends completely on the slab you choose and the finish. A polished slab with small, speckled grain in a beige or brown range can read as a two thousand ten builder look. A honed or leathered slab with bold movement in a cooler gray, black, or blue tone reads differently. Granite has not changed. The trends have. Picking the slab in person lets you match the stone to the cabinet color and door style you are actually using, so you do not end up with something that fights the room.
Granite color names are trade labels, not precise color standards. Two bundles with the same name can have completely different levels of veining, background shade, or crystal size. Even within a single bundle, slabs vary. One slab might have a dramatic mineral pocket while the next is clean. If you order by name only, the slab you get might not be the slab you expected. Walking the floor and tagging your lot removes the surprise.
Weight is the practical one. A three centimeter granite island overhang past about ten inches often needs corbels or a steel bracket set into the cabinet. That is extra work and cost, and if it is skipped, the stone can cantilever more stress than the cabinet frame is built to hold over time. The other downside is that seams, while tight, are never invisible. In a long run you will see a line under certain light. Fabricators can minimize it with good epoxy color matching, but it is still a seam, not magic.
