Should I use granite or marble for my countertops?
Although both are stones and both are quarried from the earth. Marble's relatives (limestone, onyx and travertine) are very different from each other. The marble
family starts out as sediment – animal skeletons and shells, plant matter, silt – at the bottom of bodies of water. After millions of years this solidifies (lithifies) into stone. Because its main component is
calcium, it can be affected by acids such as vinegar and citrus beverages. Granite is formed deep in the earth's mantle at extremely high temperatures, and is a very hard stone made of crystallized minerals.
What do I need to consider when purchasing marble or granite?
Granite is one of the hardest materials on earth. Granite is composed primarily of quartz, feldspar and mica. Other minerals may be present in
the stone creating its unique colors, textures and patterns. Used as a countertop material, it is resistant to scratches, acids, stains and heat. It is enduring, hard-wearing and obtainable in a wide selection of
colors, textures and unique crystal patterns that create a warm and inviting atmosphere for you kitchen or bath. Marble works beautifully especially in
the bath where the veining patterns and colors that appear can be used to create superb designs. Marbles are made up of mostly of calcite. Marble is receptive to acidic foods such as vinegar, lemon, tomatoes, wine,
as well as some tile cleaners, mildew removers and other materials commonly found in the kitchen or bath and will dull a polished finish.
Should I use marble or granite for my kitchen countertops?
Although typical application of marble is for the bathroom vanity tops, Jacuzzi tops and fireplaces, it is possible to use it in the kitchen. However, due to the fact that
it is easy to scratch and is affected by acidic substances, such as vinegar's, ketchup's etc., we don't usually recommend it. Moreover the high-gloss of the marble countertop can be partially lost as many chemicals
etch its surface. Granite in turn is considered the second hardest stone, its polish is not subject to etching by household acids, or scratching by knives and pots and pans under normal use. It is also not affected
by typical kitchen heat such as hot pans.
Is it necessary to seal stone?
Since mineral surfaces are quite porous they absorb liquids, which may result in discoloring and staining. Although there are many commercial grade products available on
the market which may bring the stone to its to its original luster, taking simple precautions and regular maintenance can save a lot of trouble and cost. All marble an granite tops are sealed immediately after they
are installed. The impregnating substance penetrates the stone clogging most of its pores making its quite impervious to alcohol, juices, soft drinks, cosmetics, cleaners, coffee, food and even oil. With course of
time, depending on how heavily the tops are used, the sealer gets washed out. The clear indication of this happening would be the fact that the liquids are easily absorbed into the stone leaving temporary (if
promptly wiped off) stains.
Do I have to buy the whole sheet/slab?
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 he 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.
What is the best way to clean marble and other stones?
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" type cleaners contain pumice, which is powdered volcanic stone, and might damage your stone countertops or floors. Never use any product which 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.
How do I deal with sink and stove cutouts?
With our water jet technology we have the ability to cut any sink or surface unit cutout with computer aided design files. Under mount sinks (sinks that are mounted under
that countertop so as not to show any rim) are fully cut out, then the inside of the hole is polished. The countertop is then flipped over and fitted with special grommets for your plumber to fasten the sink. Self
rimming cutouts are cut 6" into each corner leaving some of the straight section to be cut in the field to facilitate safe shipping.
Can I cut on my granite countertop?
Can my granite top be damaged?
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.
My little sample of granite has pits on the surface – will I have these on my kitchen counters?
Granite, which is crystalline in structure, always has tiny pits – 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 as well, which may look like cracks, but are not structural defects and are a naturally occurring result of the immense heat and
pressure which 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 manmade
How do I clean my granite tops?
POLISHED GRANITE is a very durable stone. Much harder than marble. Granite has been used in the past in the commercial industry. Some of the obvious applications have been
panels on the outside of buildings, walls, and floors of "high-traffic" areas. Granite will withstand almost any element it comes up against including heat and cold. Granite itself is approximately 95-98%
stain resistant but, we use a silicone impregnator on all our natural stone products. This will insure lasting life and beauty. Polished Granite should receive the same cleaning care as polished marble, using a mild
phosphate-free, biodegradable liquid dish-soap, soap flakes or powder which contain no aromatics. Followed by a through rinsing and drying with cotton-flannel or chamois.
Will my granite look like the sample?
The samples you see on the computer have been scanned and saved as digital images. The color tones may not be absolutely correct due to variations in computer systems,
monitors and compression algorithms. Also, granite is a natural material with naturally occurring variations in color, tone, granularity, pattern, etc. These variations are expected and are the source of its natural
beauty.
Can I set hot pot on my granite countertop?
Can granite chip?
Can granite seams show?
Because granite is a natural material and is mined from the quarry in blocks usually no more than 10' long, you will end up with seams. Also, because granite is sold in
rectangular pieces, you may want to use seams to reduce your costs, such as in an 'L' shaped corner. The visibility of seams will depend on the granularity, color and pattern. A small, uniform grain (such as Regal
Grey) will not be as apparent as a larger varied grain (such as Deer Island). A dark color (Spring Green) will be less apparent than a light color (Pine Green). A dramatic pattern with swaths of color (Kinawa,
Paradiso) will show more seams than a uniform pattern (Dakota Mahogany). Most customers have found that the beauty of natural granite outweighs the concern of seams.
How are seams made?
Seams are done where the granite joins with a smooth, straight cut During installation, a small bead of silicone is placed along the seam to seal it. Occasionally, in
areas of stress or without sufficient support, the seams will be joined with epoxy, which must be supported temporarily until the epoxy cures.
Does Granite stain?
For the most part, granite does not stain. While it is true that stone is a porous material, of all the stones, Granite is the least porous. A sealer is
also applied to the stone when it is installed to further protect it from this possibility. Water left on a Granite countertop for a long period of time will show evidence of moisture. It will however evaporate
and the "dark spot" will disappear. Oil left on a Granite surface will slowly be absorbed into the stone. It is recommended that any spills be wiped up when they occur. If the spill is not caught in time
and a stain does occur, a poultice may be applied to draw the oil back out of the stone. Over time the oil will naturally redistribute itself in the stone until it becomes virtually undetectable.
Can granite crack?
Can granite cantilever?
Can I use marble on my kitchen counters?
Yes. In fact, marbles that have a honed finish will not etch because its surface starts out with a matte finish. Because marbles (and limestone and travertine) are calcium
carbonate, the polished surface is more vulnerable to household acids including vinegar, mustard, catsup, citrus and a host of other food-related products. These acidic substances cause a chemical reaction which
will remove the polish.
I want to know how heavy my countertops will be. How do I calculate the weight of a piece of granite?
Granite has a density of .097 pounds per cubic inch, with some variation depending on the stone. So for example, a countertop piece measuring
60" x 25" x 1.2" (thick) = 1800 cubic inches x .097 = 174.6 lbs.
How often should I seal my Granite countertops?
Why doesn't my Granite look exactly like the sample?
The samples we've selected for our showroom are generally indicative of the coloring and pattern (also known as veining) of each stone. As the Granite is
quarried, differences in the stone's shading and pattern will appear. While we try to remain aware of the current tendencies of each stone, sometimes even we are caught by surprise. Since Granite is a natural
material and subject to such changes, we recommend that a customer view the slab prior to fabrication to ensure complete satisfaction.
How scratch-resistant is Granite?
With normal daily use, even cutting directly upon it, you will not mar it's finish.. Unlike any other surface, Granite will not lose its shine.
How do I care for my Granite countertop?
Are there other finishes for Granite besides the high polished surface?
What is the difference between an under mount sink and a drop-in sink?
A drop-in sink sits on top of the cutout and adds no additional cost to your project. Those that are cost conscious usually opt for this choice. An under
mount sink sits beneath the polished rim of the cutout. The benefit to this option is that it provides a smooth surface from counter to sink. Because there is additional polishing involved, there is an up-charge per
sink cutout.
What is a "high-movement" stone?
Different Granites have different patterns or veining. Some stones rarely change in their tight quartz-like appearance, while others have veins that swirl
and change irregularly. Since samples cannot give a good overall picture of a high-movement stone, it is wise to see the slab prior to fabrication. For some, the unique pattern is intriguing and adds to the beauty
of the stone. For others the effect can seem somewhat chaotic.
Are Granite countertops expensive?
Can I really do this myself?
You don't need to be an expert, but you should have some good experience with general carpentry, renovation, etc. Read the Templating and
Installation sections to get a handle on what's involved. In most instances, the job can go smoothly, but sometimes you may find some difficulty when an expert or some experience is necessary. (For instance, you may
have to adjust a seam with a diamond saw if your walls aren't square and your template didn't reflect the angle). You can always hire an expert to do the templating and installation - a countertop person, tile
person or kitchen person can usually handle this assignment.
How do you take care of Granite?
How are sinks done?
Sinks are either drop-in mount or under mount. Sinks come in a variety of materials, including stainless steel, ceramic and enameled cast iron
as well as some synthetics. A cutout needs to be made in the granite to accommodate the sink. The sink will have directions and a template for the cutout. If you are doing your own templates, the sink must be
precisely located and the cutout indicated exactly. You must also send the sink template with your plastic templates.
You must have a minimum of 3" and preferably 3 1/2" of granite between the sink and
edge for structural integrity.
Do Granite counters overhang the cabinets?
Can I use the granite that remains from a cutout for a sink or cooktop?
What are the advantages of having granite?
Isn't granite porous? What about sealers?
Granite is the next hardest material to a diamond. There are some granites that are more porous than others however, all of our granite
countertops are sealed during the fabrication process and again upon installation. The rule of thumb is that when the water no longer beads up, it's time to re-seal. For some folks that's two years, for some it's
4-5. It depends upon usage.
I've heard that granite breeds bacteria, is that true?
How do I clean my granite countertops?
Are the seams very noticeable?
First of all, we try to give you the least number of seams possible. This varies depending on the size of the slabs and your particular counter
top or island design. Seams are approximately 1/16" in width. They are done with epoxy and mixed with stone dust along with a color pigment to match your stone.
Aren't all granites dark-colored?
No. There is a wide range of colors to choose from to match any decor and compliment any cabinetry. You can find granites with green, blue,
yellow, beige, taupe, mauve, pink, peach, gold, red, black, gray and brown.
Where do I go to view and select a granite?
How long a process is it to get granite installed?
A deposit is required to order your slab material. Installation is approximately 6-8 weeks from time of deposit. If you are having new cabinetry
installed, all of the new cabinets must be in place in order for us to template. Delivery of your finished tops is approximately 7-14 business days from time of template.
Where do you obtain the stone?
Our stone is quarried all over the world. Most of the blocks are shipped to Italy for cutting and polishing and then port on the east coast before being
shipped to our suppliers. Prescott Stone only uses suppliers who provide select granite. We never purchase "seconds" or go through disreputable suppliers. Mostly, we purchase from suppliers in Atlanta and
Washington, D.C. but we have suppliers as far away as New York and Florida.
How long does it take once we sign a contract?
Our schedule is usually booked eight to 12 weeks in advance. From time to time, jobs become delayed. When this happens, we can start your job earlier by slipping you in.
For remodels, from the time we make templates until we return with your stone, is usually seven to ten business days. For new construction, it is usually a minimum of 14 business days.
What do you do with the leftover stone?
Prescott Stone only charges you for the material that is actually used. Therefore, any remaining material is the property of Prescott Stone. Because you are charged for
the material in sink and cooktop cut-outs, these pieces technically belong to the customer. If the customer wishes, we can deliver them or, for additional cost, re-cut and polish them into bread boards.
How can I know what my stone will look like if it is special ordered?
Our suppliers will provide us with a sample from the acutual slab(s) to be used on your job. This allows you to see the quality of polish, the color and the composition.
We often request Poloroids and digital images to go with the samples. Also, customers are directed to suppliers in the area so they may hand-pick their selections.
How much do granite countertops cost?
The least expensive granites are comparable to the more expensive solid surface materials. Many factors are considered when we price a prospective job: price of the
stone, size of the slabs, the type of edge, the number of holes to be cut, and other details, too. This is why we have a strong preference for meeting with you before any pricing is provided.
What is the thickness of the stone?
How do I maintain my granite?
Soap and water! We will provide you with detailed instructions but the bottom line is just soap and water. Prescott Stone seals all of the slabs before cutting even
begins and this protects your stone from staining. You should re-seal after the first year and then every three to five years as needed. Oil spills can be problematic so, if you spill oil on your
counters, clean it up as you go and do not allow it to sit on the stone for any length of time.
Where is my stone from and how does that affect the price?
Granites come from all over the world: India, Egypt, Spain, Brazil, Norway and Africa to name but a few. Canada and the United States also have some very lovely
granite as well. Where the stone originates has no impact on the cost of the stone. It is more a matter of supply and the demand placed upon the quarry. The red Granites and blue Granites tend to be
priced a bit higher than other colors. We recommend that you simply pick a color range you like, and then find the stone that fits your budget from there.
How durable is marble?
Marble has been used for thousands of years. In many cases, the statues and buildings made of marble far outlasted the ancient cultures that built them. A simple,
regular maintenance program will keep marble looking beautiful for the life of your home or commercial building.
Can marble be used in kitchens and bathrooms?
Yes. Marble is a durable material that adds elegance to any room, including bathrooms and kitchens. Since marble is more porous (and therefore softer) than granite,
it is more prone to staining, etching and scratching. We recommend that a penetrating sealant be applied on a twice-yearly basis to help protect the marble from damage. Marble can even be used for kitchen
countertops, although our policy at Global Granite is to recommend granite as a first choice for countertops. Green marble is the most durable and least susceptible to staining and scratching. With any marble,
care should be made to wipe up spills immediately and we also recommend using a cutting board to protect against scratching. Marble is an excellent choice for bathrooms and powder rooms giving a luxurious quality
to vanities, floors, tubs and showers.
Can natural stone be used on the exteriors of commercial buildings and houses in the Midwest?
What are the differences between 3/4" (2 cm) and 1 1/4" (3 cm) material for countertops?
Slabs, large pieces of stone, come in 3/4" (2 cm) and 1 1/4" (3 cm) . For the most part there is no difference in durability or usage. The choice depends on the type of
edging you want. You can see a variety of edge samples in our showroom.
Can I get tiles to match my countertop or vanity top?
Many, though not all, of our stones are available in both tiles and slabs. We offer tiles in standard 12" and 16" sizes, as well as mosaic borders and some tumbled
materials in 6", 4", 2", and 1" sizes. Keep in mind that tile and slab materials vary, so we recommend that you view both in our showroom before making your final decision.
What type of stone is best for my project?
Marble, travertine, limestone and soapstone are recommended for areas that have light to normal use. These materials are excellent choices for fireplace surrounds,
furniture, tub tops, shower enclosures and bathroom vanity tops. Granite slabs are much harder and more durable. Granite is recommended for areas that receive heavy use such as kitchen counter tops and kitchen
floors.
What's a fabricator?
Fabricators are the people who actually cut and shape the slabs you've selected into countertops, vanity tops, fireplace surrounds, furniture or other items you've
designed.
Why do I need to send in a drawing of my project?
Sterner Marble & Granite, Inc. will give you a price estimate based on the dimensions and details of your particular project. The estimate will include materials,
fabrication and installation. Estimates could change based on actual "on site" measurements. Please include information on your sinks, (under mount or top mount) faucets, stove (slide in range or cook top)
and back splash choice.
What's an edge detail?
Edge detail refers to the edge size and shape of your finished project. In terms of size, most slabs are cut to a 3/4" thickness. The exposed edge of your finished
project can remain at 3/4" or be "laminated" which results in an 11/2" finished edge. Laminated edges are often chosen to provide an attractive overhang between counter tops and cabinetry. The
second component of edge detail is the shape. There are many different shapes to choose from. Popular shapes are eased, bullnose and ogee. Most qualified fabricators have the equipment to create whatever edge shape
you request. Our website has several examples of edge details.
How long will it take to fabricate my project?
What is demolition?
What's templating?
What do I need to do to prepare for templates?
Why can't Sterner Marble & Granite do the demolition and preparation work for my project?
Stone fabrication and installation is a specialized trade. It requires several years of training and experience to be adequately qualified to turn a slab of stone into the
finished piece you've dreamed of. Most fabricators are not involved in other trades. Our expertise is not in the construction or adjustment of cabinetry, sub-tops and framework. We also are not qualified to perform
the removal and installation of appliances and plumbing fixtures. We can however, refer you to several qualified contractors we have worked with.
I've asked for proposals from other fabricators also. Why are the quotes so different?
In order to make a true comparison make sure that all factors are equal. For example, do all the bids use the same stone slab material? Compare edge details? Does each bid
have a laminated edge or are you comparing the price of an 11/2" laminated edge to a 3/4" non-laminated edge? Do all bids include installation? Are all chargeable items included in the quote? Ask if back
splashes, sink holes, faucets and cook top cut outs have been taken into consideration. These specific items need to be addressed before you make your final decision.
What is honed granite?
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. Cold Spring uses a special process called "Velvet" which 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.
I'm using granite in my entryway and I want to continue it outside, but I'm afraid it's too slippery.
Flamed granite, which has a very textured, non-slippery surface, when treated with a color-enhancing product, can be used to carry out your design.
