General Questions

Where do you operate?
All Granite and Marble Corp. operates within the greater TRI STATE area - NJ, NY, CT and PA. We are a direct fabricator and installer of kitchen countertops, vanities, Jacuzzi surrounds, fireplace surrounds, and custom designs.
Do I have to buy a whole slab?
No. We will determine how much material is needed for your countertops. We do not charge you the price of full slabs. You pay for what is required to fabricate your tops.
Can I take my child to your yard/warehouse?
Children under 16 years of age cannot enter the stoneyard/warehouse areas of our facilities because of safety and insurance regulations. These are potentially dangerous areas, with motorized heavy equipment (forklifts, trucks, cranes, vans, boom trucks) transporting heavy and unstable loads, such as individual slabs, and bundles of slabs.
I need a Certificate of Insurance from you. How can I obtain one?
Requests for a Certificate of Insurance must be made in writing and presented to the Location Manager.
What is your relationship with Mr. Stone?
All Granite & Marble and MrStone.com are two separate companies.We have partnered with MrStone.com to provide sinks and accessories to our customers. MrStone does not have a store front, and does not accept walk-in or pick up orders.
Can I do my final slab selection on Saturday?
Saturdays are the busiest days of the week for our company. With the majority of our customers browsing our stone selection for the first time on Saturday, removing slabs from A-Frames in order to lay out templates becomes dangerous. Certain exceptions can be made, however, with the approval of the Sales Manager.
Can I take my car to the yard?
No customer vehicles are allowed in the stoneyard for safety reasons. If you are in need of mobility assistance to browse our selection, we can accommodate you with our courtesy cart or wheelchair.

Product and Maintenance Questions

What's the difference between Granite and Marble?
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, limestone, travertine, marble, onyx, starts out as sediment, animal skeletons, shells, plant matter and silt at the bottom of bodies of water. After millions of years this solidifies into stone (lithifies). Because its main component is calcium, it can be affected by acids such as vinegar and citrus beverages.
Should I use Granite or Marble for my kitchen counter tops?
Although typical application of marble is for bathroom vanity tops, Jacuzzi tops and fireplaces, it is possible to use it in the kitchen. However, we don't recommend it due to the fact that it is easy to scratch and can be etched by acidic substances, such as vinegars, ketchups etc. 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, 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 most mineral surfaces are 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 original luster, taking simple precautions and regular maintenance can save a lot of trouble and cost. All of our marble and granite tops are sealed immediately after they are installed. The impregnating substance penetrates the stone clogging most of its pores making it quite impervious to alcohol, juices, soft drinks, cosmetics, cleaners, coffee, food and even oil. With the course of time, depending on how heavily the tops are used, the sealer gets worn 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. You should re-seal your marble every six months and your granite every 12 to 24 months. For best results, it is recommended to use the same sealer which was used initially. You can obtain it from www.mrstone.com.
What is the best way to clean natural stone surfaces?
The best way to clean stone countertops is to use our AGM daily granite cleaner. It's a safe and effective way of removing stubborn dirt and grime while revitalizing and sealing the surface. This cleaner can be purchased from MrStone.com. An old and inexpensive method of cleaning granite tops is to use warm water mixed with dish detergent. It is important though, to make sure that the surface is thoroughly rinsed afterwards, to prevent soap scum buildup.
What is the appropriate thickness for a kitchen counter top?
A kitchen countertop should be an inch and a quarter thick for structural reasons. Bathroom vanity tops can be thinner.
Can I cut on my countertop?
If your countertop is made of granite, you can. Granite is extremely hard and can withstand even the sharpest knives. It's not a good thing for your knives though. They can get dull in as little as one use. We recommend using a wooden or plastic cutting board. Other stones are not as resistant to scratching and so we do not recomment cuting on them.
Can stone cantilever? What is the maximum overhang size?
You can cantilever granite up to 14" 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. Other types of stone are not as strong and cannot be cantilevered as much.
Can damaged piece of stone be repaired?
If any damage occurs it can usually be fixed with a mixture of epoxy and ground up chips of stone. In most cases the repair is hard to spot.
Do seams show?
Because granite is a natural material and is mined from the quarry in blocks usually no more than 10ft long, you will most likely end up with seams. Also, you may want to use seams to reduce your costs, such as in jacuzzi surround fabricated with seams, as opposed to a single piece. The visibility of seams will depend on the granularity, color and pattern. A small, uniform grain (such as Uba Tuba) will not be as apparent as a larger varied grain (such as Peacock Green). A dark color (Platinum) will be less apparent than a light color (Imperial White). 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.
Will my chosen color look like the picture on your website?
The samples you see on our website have been photographed 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 order kitchen countertops for pick-up?
The average homeowner typically doesn't have the capability to safely transport and install large pieces of stone. The homeowner would need a pickup truck with an A-frame, as well as a crew capable of safely lifting and carrying all of the pieces, using proper techniques for lifting and transporting of stone. Additionally, we do not offer any warranty on pickup orders, and once the stone is lifted from the cart, it becomes the property and responsibility of the customer. All of these factors outweigh the potential savings to the customer. Smaller orders, like vanity tops, coffee table tops, saddles, etc., are generally small enough to fit in a regular car or van, and are simpler to install.
Are some edge profiles better than others?
Although most edge profiles have similar general characteristics, there are differences which can have an effect on daily usage. One concern is durability. Edges with smooth, rounded profiles tend to be more resistant to chipping. Another aspect of edge performance is ease of cleaning. Edge profiles which feature sharp creases, such as the Cove Dupont or Waterfall edges, tend to collect dust and grime and are tedious to keep clean. The Full Bullnose edge, because of its roundess, tends to carry spills over to the cabinet surfaces which may, over time, lead to damage to the cabinets, especially around the sink area. Also, because the bottom edge is rounded, it is not visible when viewed from above, and makes the countertop appear thinner, which is usually not a desirable effect. On the other hand, parents of small children may consider the rounded bottom edge to be safer.
Can you polish a material that is honed, like limestone?
Certain materials, like marble, limestone, slate, and travertine, have honed finishes because they are not dense enough to create a fully polished surface. Stones like this cannot be polished. Additionally, granites that come in Honed surfaces usually are also available polished, so you can avoid the costly polishing process.
Do you sell stone sinks?
We carry a small selection of Onyx, Marble, and Granite vessel sinks, and can custom fabricate undermount and farm sinks. However, it should be noted that our custom fabricated sinks are assembled from 1 1/4" slabs, rather than carved from a block of stone.
Can you hone CaesarStone™?
We do not hone CaesarStone™, but it can be specially ordered with a honed finish directly from the manufacturer.
What edge profiles can be used with CaesarStone™?
All of our popular, premium, and laminated edges are available for use on CaesarStone™.
What is the standard overhang for kitchen and bathroom counter tops?
For kitchen countertops, the average overhang is 1.5" on the front, and 1" along the sides. Bathrooms will usually have even overhangs at either 1" or 1.5". These sizes are not mandatory, and you're welcome to choose any size of overhang.

Granite Specific Questions

What should I know about Granite?
Granite is a natural stone. It is very hard and durable, heat and scratch resistant as well as easy to maintain. Aside from the practical aspect, granite is very versatile in the design field. It comes in various colors and patterns. We stock more than 1000 colors to choose from on site. All stones are not exactly the same, each lot will have unique characteristics attributed to the specific granite. Because it is a natural stone, it has been blessed with a remarkable natural beauty that has captivated humans throughout the ages. Inherent in such natural products is a certain lack of predictability that architects and designers celebrate. Consumers who are less acquainted with the material often expect the stone to be identical to the picture or sample they were shown. Although sample stones are intended to be representative of the quarry's product, the material quarried at one time may differ slightly in color and veining from the sample. Moreover, even a single marble or granite slab will possess a certain amount of color variation from one end to the other. Interior designers and architects have come to view this tendency of natural stone as an advantage. Slight irregularities can be pleasing, introducing an element of the natural into human-designed spaces, whether residential or commercial.
Can granite surfaces be damaged?
Like any solid surface, high impact blows can harm granite. Because of its crystalline structure, it can chip if subjected to sharp tipped hard objects. Unsealed, granite can absorb stains such as oil, which can ultimately cause dark spots or discoloration. Fortunately, under typical household use, granite is not subjected to such events. Also, heat from pots and pans or burning liquids will not affect granite under normal circumstances.
My granite sample has pits on the surface. Will those be present on my finished countertops?
Granite, which is crystalline in its structure, often has tiny pits or spaces between the various mineral crystals. It's hard to 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 should not be expected to look manmade.
Can I set a hot pot on my granite counter top?
Granite is formed by extreme heat combined with pressure occurring beneath the earths crust. It is extremely unlikely that a granite countertop would crack or discolor when subjected to a hot pan.
Can granite chip?
Only in cases of severe abuse with a hammer or impact tool. A chip can be filled with a granite dust and epoxy mixture. If a chip occurs on your countertop, do not throw out the chipped pieces. We can use them to fix the countertop, so that no one will be able to tell it was ever chipped.
Does granite crack?
No, not with regular use. Granite is most susceptible to cracks during shipping and installation. Normal use will not overstress this durable material.
Does granite stain?
Most natural stones are porous to some degree. Granite has very little porosity. Most colors will never show any moisture. A few colors may show some moisture if exposed for a period of time. For example, a puddle of water left on the counter for 30 minutes for some colors, may show a dark spot when the water is wiped away. This spot will then dry up and no evidence will show. Only a few colors demonstrate this trait. Our installers will seal the countertops after they are installed. Also if AGM daily granite cleaner is used there will be no need to reseal the countertops because cleaner contains some sealer and every time the countertops are cleaned they are also being sealed at the same time.
How is granite formed?
Granite is an igneous rock of visible crystalline formation and texture. It is composed primarily of feldspar, quartz, and mica. It starts off as liquid magma deep within the earth's core where it is cooled and compressed over millions of years under tons of pressure. It is then quarried, cut and polished. After that process it can be applied in various ways like kitchen countertops, vanity tops, fireplace surrounds as well as Jacuzzi surrounds and other custom designs.
Is granite expensive?
The cost of granite counters can vary a lot depending on the color, edge profile and custom shapes used in the layout. Our pricing is very competitive and hard to surpass when you consider the total value of our services. Use our Instant Online Estimate tool to get your price right now. It's absolutely free and takes just minutes to complete.
How much does granite weigh?
One square foot of 1 1/4" thick granite usually weighs 16-18 lbs.

Marble Specific Questions

Can marble be used as a kitchen countertop?
Most marbles are too soft and porous to be safely used in the kitchen. Even the more resilient marbles are susceptible to staining and should be avoided if you intend to cook or serve food often. None of our marbles are covered by any type of warranty when installed in kitchens.
Where can I use marble?
Marble can be used for a number of applications such as fireplace surrounds, tabletops, saddles, and shelves. It can also be applied in the bath area as Jacuzzi surrounds, vanities, floor, and shower paneling. Generally you can safely use marble in low traffic areas.

Order Process Questions

What is the ordering process?
The whole process is designed for quality and speed. First, get an estimate by giving us your layout and dimensions (online, fax or in person). Come visit our yards to select the stone of your choice. After that an order can be placed and we will schedule a templating appointment. From the time the template is made you can expect a turnaround time of 2 to 3 business days. You can see the full Order Process here.
Can you level my cabinets?
All Granite & Marble does not engage in ANY carpentry work, so all cabinets must be fully installed and leveled, prior to templating.
Do you install stairs?
Although we install stair treads and risers for indoor and outdoor applications, we do not build the structure of the stairs. Due to the significant amount of weight added by the stone, the structure should be designed by a structural engineer, in order to support the added weight.
Do you install door saddles?
We do not offer such service. Installing Door Saddles is the final step when installing floor tiles. This can only be done by the tile installer.
Can I choose a stone from any of your warehouses or do I have to pick from the one closest to me?
The stone selection in each of our facilities is similar for the most popular colors, so clients should visit the location closest to them. Additionally, the color selection in each of our yards is vastly superior to that of our competitors. If your local All Granite stoneyard does not have a color that suits your tastes, you're welcome to visit our other yards, however, take note of the fact that factors such as turnaround time, and pricing may change due to the increased distance between the jobsite and facility that the stone was chosen from.
Do you make and install sink supports?
Sink supports should be made and installed by a carpenter or contractor. Sinks requiring supports should be fully installed prior to countertop templating. Supports should be made to uphold the weight of very heavy cast-iron sinks, and to securely mount sinks with a front apron.
Can I buy a slab somewhere else and have you fabricate it?
With approval from the production manager, we can fabricate slabs from outside sources, however since we have no information on the soundness of the stone, we take NO responsibility for any problems arising during Fabrication.
Will you help me with color selection?
Our staff is always happy to help you select a stone color for your project. Our sales reps have been trained in design principles, and have worked with many homeowners just like you. Our website is also an extremely valuable resource, with plenty of photos and videos of completed projects, and advice from our experienced moderators and affiliated professional interior designers in our forums and online chat.
Can your templating technician give me advice on design, shapes, etc.?
While our Templating technicians can offer suggestions as to the technical aspects of your project, including the size and shape of overhangs at seating areas, placement and sizing of sinks and faucets, custom bumpouts, corner designs, and support for stone pieces, they are not trained to offer advice on color selection, and other elements of interior design. Again, our website is a terriffic resource for design ideas and solutions.
Do I need the faucet at the time of the templates? When do you drill the holes?
While the holes for the faucet are not drilled until the countertops are installed, we require the homeowner to have the faucets available during templating so we can make sure there is enough room for the faucet and sink in the base cabinet. For example, a faucet with a tilting handle would require more space in the back, especially if there will be a stone backsplash installed.
How many slabs can I see when finalizing my slab selection?
The number of slabs shown to you depends on the size of your project. We normally show you the amount of slabs needed to fabricate your countertops plus the next available slab. Each bundle of stone imported from the quarry consists of consecutive slabs, cut from the same block, which is sliced in the same way as a loaf of bread. There is very little difference in color and pattern between consecutive slabs, so the whole slab will be virtually identical from slab to slab. Although Granite is a very durable and scratch reisistant material, it can be scratched by diamonds or other granites. Therefore, we try to minimize the number of times the slab is moved to assure that each customer gets a scratch free slab. When the stone is unloaded from the container, the whole bundle is placed onto the A-Frame and the slabs remain untouched until they are needed for fabrication. This strict company policy allows us to minimize the number of damaged slabs, and assure each customer that their chosen slab will be impeccable.
How long do I have to wait until I can use my countertops after they are installed?
The countertops can be used immediately upon the completion of the installation process. The sink however, should not be used for 6 hours after the installation, to allow the epoxy which holds it to cure.
Can granite be used as a vertical support (for example a table base)?
Granite on its own cannot be used as a weight bearing support for any application. However, if a wooden structure is created to bear the weight of the table top, granite panels can be used as decorative cladding on the sides of the wooden box. A box for such a purpose must be prepared by the customer, using a structure made from 2x4's and covered with plywood sheets. This structure must be brought to our facility in order for us to install the granite. Additionally, jobs of this nature are usually considered a pick up order, however we can arrange to deliver the finished base.
I chose a cast iron or farm sink for my project. How should I prepare for templating?
Apron sinks and cast iron sinks must be installed on a specially built support, as they will not be secured to the counter top. In order for our installers to properly cut the opening for the sink, it must already be installed on its support cabinet at the time of templating.

Price and Estimate Questions

What is your payment policy?
The payment procedure is very simple. For projects measured and installed by AGM, we collect a 50% deposit at the time of templating. The remaining balance is required at the time of installation. With pick-up orders, a 100% full payment is required upon placing the order. In either case, the payments should be in the form of a certified check or money order, in order to guarantee the fastest possible turnaround time. Personal and business checks are accepted for deposit only, but require a 5 business day waiting period, which delays the project's completion. For jobs installed by AGM, the final payment MUST be certified.
What information is required for a quote?
We require our potential clients to provide a top view layout of the project, including dimensions along with personal information such as name, town, state, zip code, a phone contact, and if known, the name of the stone and the desired edge finish. We can then process the specific measurements and respond with an estimate for the job. This information can either be faxed to us or brought to our showroom when the client comes in for a walk in our yard. You can also use our Instant Online Estimate tool, which allows you to create a digital drawing of your project and get a price in just minutes.
Is installation included in the quote?
Yes. If you would like to get a quote without installation, please indicate "pick-up" on your request.
If I fax my drawing with dimensions to you, how long will I have to wait for a quote?
Proposals for free quotes that are faxed over are given a 24 hour time frame. We will either call or fax over the estimate assuming that the contact information is provided to us in the original fax. You can always use our Instant Online Estimate and get your quote in minutes.
How close does the estimate come to the final price?
The quote on the estimate is based on the measurements provided to us by you. So the more accurate your drawings are, the more accurate the price.
What do the five columns on the estimate mean?
The five columns on the estimate represent the different price groups of granite. Each column contains stones that correspond with the given price. The five categories are single blue, double blue, single silver, double silver and gold. The single blue and double blue category is our super sale materials. The single silver and double silver is our promotional materials, gold represents our premium stock. In addition to the five columns, some material falls into double gold and super gold categories. These groups require a detailed estimate that can only be processed by a manager of the sales department.
Why are some stones more expensive than others?
There are several factors which determine the price of each stone. First there are costs of mining. Some stones are located in hard to reach areas which increases the costs of mining. Then, depending on where the stone is sent from, the cost of shipping comes into play. Finally, the stone market follows the supply and demand economics, so rare and sought after stones will be significantly more expensive than common and popular stones.
