Prefabricated means prefabricated granite. It is mass produced in China and India mostly. The sections are cut while the edge detail is already finished, which cuts back fabrication time and cost for the shop. It is shipped here in containers ready to to be installed.
Prefabricated granite is good for multi-unit projects, apartments, condos, hotels rooms, small bathrooms, and tiny kitchens, although you could get a higher-quality piece of granite from our scrap yard at a price as good as prefabricated. Your project must be straight and square because prefabricated cannot be used on splays and curves. If you have a large island, prefabricated cannot be used on that either.

No. Here are some of the pros and cons of prefabricated granite tops:

Prefabricated comes in standard widths. It also comes in one standard edge choice.

Does not seam up as well as custom fit to order slab countertops.

Prefabricated has limited color choices (usually plain ones, in lower group granites), and in most cases, does not increase the value of the property.

It offers a wide variety of edge choices and endless colors.

Custom slab granite, on the other hand, offers fewer seams, comes in non-standard widths, and can be shaped in almost any dimension.

Professionals can. The consumer may not notice the difference, as many companies install prefabricated without the customer’s knowledge. When a bid is incredibly low from another fabricator’s bid, it is usually being estimated as prefabricated. It’s always good to ask the company you are dealing with if you are getting custom slab countertops.

Simply call us, and we will send a representative from our company out to your home or wherever the project is located. They will have a good selection of colors and samples for you to choose from. They will give you a written estimate on a form breaking down every detail, including the labor cost and the material cost separately, so you can see where your money is being spent.
If you decide to hire us, a deposit is required. After the deposit is turned in, we will send someone else out within a week to perform what’s called templating. Templating is the exact cutting measurements that will be performed on your counters. We will need your new sink at the point of templating. If you did not purchase your sink through us, you will need to have it on site at time of template. Once the template is turned in, your granite should be installed within two to three weeks, depending on the work pace of the shop.

Certainly. Please make all the measurements as accurate as possible and allow for an 1.5 inch overhang on all the cabinets. Mark special areas (curves etc.), indicate your preferred edge(s), colors, and details of your sink (undermount or drop-in). Also indicate whether we will need to remove your old countertop and backsplash. While estimates done this way can be quite close to the final numbers, we cannot finalize the costs until we visit your project, measure ourselves, and discuss all the aspects of your job.

Here is the normal sequence of events:

Call to schedule an estimate.

Get the estimate and select your granite color. We will bring samples to your home.

Finalize choices (granite, sinks, faucet, cooktop etc.), schedule a templating date, and reserve an installation date.

Make sure your faucet choice goes with your sink choice.

Consider the layout for the holes that may need to be drilled into the granite.

Templates are made (remember to clear off your existing countertops).

The granite is purchased by the fabricator and cut to size, edged, and polished.

On installation day, the old counters are removed, new ones installed, and the sink is mounted.

For undermount sinks, the plumber should connect the faucets/drains on the next day, giving time for the adhesives to fully cure.

The party is scheduled to show off your new (515 million years old) natural stone countertops!

The average kitchen two-slab job takes approximately four hours to install.

We are not licensed electricians or plumbers, so we can’t make electrical or plumbing reconnections. We can, in some instances, recommend reputable and licensed individuals or companies to complete these tasks for you. This keeps us focused on the natural stone business to provide the best product for the lowest cost. When we leave your home, the sink is fully installed on (or under) the countertop, but a plumber or the homeowner will have to reconnect faucets and drain lines the next day after all the adhesives and caulks have fully cured.
Please note: The critical part for most jobs is choosing a color and locking in an installation date. As soon as you are ready to go ahead with the project, even if you haven’t fully settled on a color choice, call to set the schedule. Depending on the time of year, we have a two to four week lead time (i.e. when you decide to go ahead, our first available installation dates will be two to four weeks out).
Unlike many other fabricators, we will be able to set your installation date at the very beginning of your project and stick to it. There are always special considerations that can mix up the normal scheduling sequence, so be sure to discuss them with us during the estimating process.

Once upon a time, there was a report circulating that granite countertops were unsafe, harbor bacteria, and can produce disease. This is absolutely false. NIOSH and the CDC have no reports of granite or any other stone used as a countertop as being unsanitary. These rumors are circulated by the solid surface industry in an attempt to compete with the stone industry.

Next to diamond, sapphire, and ruby, granite is the hardest natural product on earth. Once polished, natural granite will maintain its high gloss virtually forever. Normal use of kitchen knives, cutlery, and cookware leaves no scratches. Heat has almost no effect on natural granite, making it much safer than synthetic surfaces with polyesters and resins. Pots and pans heated to 900 degrees Fahrenheit will not dull natural granite’s lustrous finish, but the use of trivets is recommended to keep your granite counter clean.
Other benefits include:

An unlimited number of colors and patterns to choose from, so matching your custom project will not be a problem

Scratch-resistant (second in hardness only to diamonds)


Cleaning and maintenance is a breeze

Not only adds distinct beauty but also adds resale value to your home

Granite is a highly dense material and relatively porous, so it can get stained if a spill is not cleaned quickly. Sealing the surface with a water-based sealant is therefore recommended to protect the granite from water patches and stains. Sealing can be done once a year or once every two years, depending on the usage of the surface.

An edge detail is the shape of the outer edge of the granite. There are many different types of edges and cost is one factor to consider when choosing a premium edge.

Slabs are always sold intact. Buying random slabs is similar to buying fabric. Like a seamstress or tailor, your fabricator buys the raw material and sells you a completed installation. In the price is included the cost of transporting the material, making field measurements and templates, cutting, polishing, bringing the pieces to your job site, and fitting them into place.
How much material the installer needs is determined by the layout and the amount of waste. The fabricator will lay out your job in a way that will minimize the amount of waste material while maximizing the natural beauty of veining and pattern. Slabs range from 45 square feet up to 63 square feet. The average slabs is figured at 55 square feet. There is normally a 20% to 25% waste factor when cutting stone.

The term granite is used to cover a group of related stones, all of which have their origin deep in the earth’s molten mantle. As this extremely hot liquid material rises and cools, it forms a crystalline, granular structure, hence the term granite. Granite and other granite-like stones are formed of hard minerals such as quartz, feldspar, and mica, which are fused together into a very hard stone ideal for kitchen counters because its polish is resistant to household acids, such as citrus and vinegar, and is hard enough to resist scratching from knives and pots and pans.

Daily and weekly maintenance is the most important factor to keep your natural stone looking its best. A good rule of thumb is never use anything that you wouldn’t use on your hands. Simply follow the instructions below:
Blot spills immediately and clean with a pH-balanced cleaner and clean cloth. The term pH refers to the potential of hydrogen and is used to measure the acidity or alkalinity of a solution. A pH-balanced cleaner will be a neutral solution, meaning that it will measure a seven on the pH scale of zero to 14.
You may also use a stone cleaner (available at most hardware stores) or a small amount of ordinary dish soap (white or clear) and water to wipe down your surface. Diluted window cleaner (50% water, 50% cleaner) also works well. Do not use old kitchen sponges because they may contain oil from your dishes and leave a film on your surface.
Squeegee shower walls daily and wipe down shower walls weekly with your pH-balanced cleaning solution.

Honed and polished refer to the finish of the granite. The finish of honed granite will range from flat to a low sheen gloss, which gives the stone a softer look. Polished granite refers to the glossy, highly reflective appearance, giving it a smooth, sleek look.

Granite is flamed by applying blowtorch-strength heat to the surface of the stone. This causes the surface to melt and some of the crystals to shatter, leaving a highly textured surface that is ideal for exterior paving or wet areas where optimum non-slipperiness is required.

Strictly speaking, granite is called honed when the polishing process is halted just before a reflective shiny surface is achieved. This gives a softer, matte appearance to the stone. Coldspring uses a special process called “velvet” that enhances and deepens the colors as well. Some fabricators can hone polished granite if they have special equipment to remove the polished surface, but this can sometimes result in wheel marks from the polishing head.

Only if you want to ruin your good knives. Granite is harder than your knife blades and will dull them very quickly if you use the countertop as a cutting surface. Always cut and chop on a wooden or plastic cutting board. Hardness is measured on a MOH scale of one to 10, with 10 being the hardest. Granite is a seven, while a stainless steel knife blade is around a six, so you cannot scratch granite with it.

Although both are stones and both are quarried from the earth, granite and marble (and marble’s relatives, limestone, onyx, and travertine) are very different from each other. Granite is formed deep in the earth’s mantle at extremely high temperatures and is a very hard, resistant stone made of crystallized minerals.
The marble family (which includes limestone, travertine, marble, and onyx) starts out as sediment—animal skeletons and shells, plant matter, and silt—at the bottom of bodies of water. After millions of years, this sediment solidifies into stone. Because its main component is calcium, acids like vinegar and citrus beverages can affect it.

Granite adds elegance and style to kitchens, baths, and other areas of the home with a richness that cannot be duplicated in synthetic materials. Granite is highly resistant to scratching, cracking, and staining. Impervious to heat, daily kitchen activities pose no problem, and it can take a hot pot without the use of a trivet. Because granite is a very hard stone that’s formed at very high temperatures deep in the earth, its polish is not subject to etching by household acids or scratching by knives and pots and pans. This makes granite an ideal choice for countertops.

Like any solid surface, high-impact blows can harm granite. Because of its crystalline structure, it can chip if subjected to sharp, hard objects. Unsealed granite can absorb stains, such as oil, which can ultimately cause dark spots or discoloration. Heat from pots and pans or burning liquids will not affect granite under normal circumstances. A chip can be filled with a granite dust and epoxy mixture.

Granite, which is crystalline in structure, always has tiny pits and spaces between the various mineral crystals. You don’t see them on a larger piece because the overall appearance is polished and mirror-like. Granite sometimes has natural fissures, which may look like cracks. However, these are not structural defects and are a naturally occurring result of the immense heat and pressure that formed the granite eons ago. These characteristics are part of the natural beauty of stone and will not impair the function or durability of the material. A product of nature cannot be expected to look man-made.

Not with ordinary use. Granite is most susceptible to cracks during shipping and installation. Normal use will not overstress this durable material. Normal use does not include standing on the countertops.

Granite is one of the hardest stones in the world. It is highly resistant to scratching in ordinary use. A knife blade will not scratch granite. It can only be scratched by another piece of granite or with specially sharpened tools designed to work with granite like tungsten and diamond blades.

In general, no. All stone, however, is porous to some extent, but granite has very little porosity. A few colors may absorb some moisture with prolonged contact compared to others. For example, a puddle of water left on the counter, for some colors, may show a dark spot when the water is wiped away. Usually, no evidence remains once the liquid is removed and the granite dries. A stone sealer is highly recommended for all granite after installation.

No. You can’t burn granite with ordinary use. It is perfectly okay to set hot pots or pans directly from the stove or oven onto granite.

Warm soapy water will do the trick. Or, use cleaners specifically formulated to help clean and protect stone surfaces.

The samples you see on the computer may not be absolutely correct due to variations in computer systems, monitors, and software compression. Marble and granite are natural stones created by the forces of nature. They are composed of various minerals and are susceptible to wide variations in color, texture, spotting, veining, and cracking. These variations are expected and are the source of its natural beauty.

Most counters overhang by 1 1/2 inches, which is standard. This may be changed for whatever reason due to cabinet configuration, cabinet installation, and/or personal tastes.

You can cantilever granite up to 12 inches with sufficient support on the fixed end and with a large enough piece. Never cantilever unsupported granite where it might receive excessive stress like someone sitting on a counter or stepping on a counter to change a light bulb. You must have support underneath for these situations.

No! It is simply supply and demand and rarity of color. More attractive stones are in higher demand, and if they come from a distant land in small quantities, the price will be higher. Some of the toughest stones are also quite cheap, and some of the most expensive can be very fragile. Also note that all natural stone contains small pits in their surface to varying degrees. These are simply small voids between grain boundaries, and some of the most expensive stones can be full of them.

Granite tiles and slabs come in different thickness. The weight per square foot for each thickness is as follows:
  • 3/4 inches (20mm) thick slab: 12.8 pounds square feet
  • 1/4 inches (30mm) thick slab: 18 pounds square feet

Most granite installations will require at least one or more joints called seams. During layout and design, we will try to minimize the number of seams required. Additionally, our care in manufacturing ensures that edges fit together very tightly to help lessen the appearance of visible seams.

Our preferred method of payment is personal check. However, we do accept Visa and MasterCard as well.


True geological marble is limestone that has been subjected to great pressure and heat, which has changed its structure to a crystalline, sugary texture. It is generally white or whitish, sometimes translucent, with some veining or color provided by other minerals present at its formation. White Cararra, Thassos, Colorado Yule, and Bianco Rosa are true marbles.
Commercially, the term marble applies to any compact limestone that will take a polish, which includes most of the colored marbles, except some of the greens.

We do not recommend the use of marble as kitchen counters because marbles (and limestone and travertine) are calcium carbonate, and their polished surface is more vulnerable to household acids, including vinegar, mustard, ketchup, citrus, and a host of other food-related products. These acidic substances cause a chemical reaction, which will remove the polish.

Additionally, marble and limestone can be scratched more easily than harder stones, such as granite. Marble is, however, sometimes used in the kitchen as a pastry slab because its perfectly smooth, cool surface is ideal for rolling out dough and pie crusts.

Some green stones, such as the jades from Taiwan, are not truly marble but a different material called serpentine. Serenities, or serpentines, as they are sometimes called, do not etch or react to acids the way limestone and marble do and are somewhat harder.

Green tiles of this family must always be installed with an epoxy adhesive to prevent the curling that can take place if a water-based setting material is used.

Marble, travertine, or limestone that is honed has a matte or satin finish, rather than a highly reflective polish. This is achieved at the factory by stopping just short of the last stage of polishing.

Some fabricators have special equipment and can hone marble in their shops by removing the factory polish. One feature of honed marble is that it doesn’t show etching as readily or wear patterns on floors. It is preferred by some because it has a less formal, softer appearance than polished stone.

Etching happens when acid in some form comes in contact with a polished marble or limestone surface. This causes a chemical reaction that removes the polish or roughens the surface of honed marble or limestone. Green marbles, such as the jades from Taiwan, are resistant to etching, and granite is impervious to any common household acids.

The old rule of thumb is never to use anything you wouldn’t use on your hands. Never use powdered cleansers or abrasive pads to clean your stone. Even “soft scrub” cleaners contain pumice, which is powdered volcanic stone that might damage your stone countertops or floors. Never use any product that is acidic; this includes substances like ammonia or many common liquid cleaners such as Windex™.

You should always use sealers and cleaning products designed specifically for natural stone.

Daily and weekly maintenance is the most important factor to keep your natural stone looking its best. Simply follow the instructions below:
Blot spills immediately.
Clean with a pH-balanced cleaner and clean cloth. The term pH refers to the potential of hydrogen and is used to measure the acidity or alkalinity of a solution. A pH-balanced cleaner will be a neutral solution, meaning that it will measure a seven on the pH scale of zero to 14.
Use a stone cleaner (available at most hardware stores) or a small amount of ordinary dish soap (white or clear) and water to wipe down your surface.
Squeegee shower walls daily.
Wipe down shower walls weekly with pH-balanced cleaning solution.
Never use cleaning products containing harsh chemicals, such as ammonia, bleach, or vinegar.
Marble is very sensitive to acidic chemicals. The acid will etch the stone, leaving it dull. Some common acidic materials are tomatoes, citrus fruits, coffee, wine, fruit juice, and vinegar.


The average two-slab kitchen installation usually takes about four hours from start to finish.
Recommendations to prepare for installations:
  • Access: Granite countertops are extremely heavy, and installers need clear access to entryways. Please have your walkways and driveways as clear as possible.
  • Cabinets: We recommend that you empty all cabinets and drawers.
  • Safety: Please remove any breakable items and cover items to protect them from dust. Granite installation can create a lot of dust. Our installers do try to control the mess the best they can. But, please remember that this is construction and it is, by definition, a messy business.
  • Faucets: Please have ready any faucets, soap dispensers, hot water taps, dishwasher air gaps, reverse osmosis filters, and any other items that need to be drilled into the countertops.
  • Sinks: Top-mount sinks will be cut on site and, whenever possible, will be done outside in a garage or in a shop. Undermount sinks are cut and polished at our shop and attached at the job site.
  • Cooktops and ranges: These will be cut on site whenever possible and done outside in a garage or in a shop, if available.
  • Dishwashers: These need to be in their final position so that we can attach them to the countertop. All other appliances need to be out of the area.


Countertop Rock LLC in Tempe, AZ backs up its work with a lifetime warranty on the seams of our countertops. This warranty covers seam separation for one year from the date of installation. In the over 1,000 kitchens that have been installed over the years, this has never been an issue.

The warranty will not cover fissures and pits in granite. Because it is a natural stone, granite may have fissures that look like cracks; these pose no actual structural problems. When selecting your granite, please look for these carefully in your slabs if you wish to avoid them.

Granite is one of the hardest substances on earth because it is heat resistant to a hot frying pan and you can cut on it. That said, it is still a natural stone, so hitting it with a hammer or a meat clever is not recommended. Countertop Rock LLC will not warranty against breakage after installation.
