Frequently Asked Questions

How much does a granite countertop cost?

This is one of the most frequently asked questions. And, the answer varies. Stone is usually quoted by the square foot and the cost depends on a number of things:

  • Actual stone you choose to use.
  • Special edges, full backsplashes, and other modifications add to the cost.
  • Using an under mount sink rather than a drop in sink entails more polishing; therefore, this also adds to the cost.

How will I know if my old cabinets can support a new countertop?

Stone countertops can weigh up to 30 pounds per square foot. At the time of template, we will make sure your cabinets are structurally sound to handle the weight of your new countertops.


Does granite countertop have a completely smooth surface?

No! Many types of granite contain pits and fissures that are natural characteristics of granite. Some granites exhibit these characteristics more than others, and the lighting of the room can make these marks more or less visible. These characteristics should be pointed out to the client prior to deciding on a particular material and pre-approval of the actual slab is recommended.


How is the seam placement determined?

Seams are determined by NJ GRANITE technician depending on countertop layout, slab sizes, support needed, and material usage. We try extremely hard to avoid seams if possible.


How often do I need to seal my granite countertops?

This depends on the sealer you choose. Some sealers need to be applied every 6 months to 1 year. Others last for 1-10 years.


Can I use my regular cleaning products?

It's not recommended. Chemicals contained in these cleaners can react negatively to your stone. They may etch some stones or even make them look dull and lifeless. It's best to use care products made specifically for stone.


Does granite chip or scratch?

Granite is a very dense material and under normal conditions it is chip and scratch resistant. However, pots, pans and other heavy objects may chip the square edge especially around a sink area. Several other edge profiles are available that will look beautiful and reduce the chances of chipping.


Can granite be repaired?

While it is difficult to permanently repair granite, it is also very difficult to damage it. However, if some damage does occur, granite usually can be repaired by a mix of epoxy and ground up chips of granite.


Why does the texture and color vary from stone to stone?

Natural stone is a product of nature and subject to variations. Characteristics such as veining and mineral deposits will affect each piece. Stone will not only vary from quarry to quarry but from stone to stone. All Natural stone is unique... no two stones are alike. This is one of the most desirable characteristics of natural stone.

Apply a sealer if needed and clean your stone regularly. Don't use acidic or abrasive cleaners.


How do I know if I need to seal my granite?

One method you can use to check if your granite needs to be resealed is to sprinkle some water on your countertop. If the water soaks into the stone and does not bead up, then we would recommend resealing your granite.


How long are the slabs, and can seams be avoided?

The average slab size is typically 98" to 115" long by 55" to 68" tall. NJ GRANITE team will work with each customer to place a few seams as possible in a kitchen. Seams are required based on slab size and may be needed to maintain the structural integrity of the countertop.


What do seams look like?

It all depends on type of material used for countertop: from 1/32” to 1/8" width filled with epoxy and color matched.


Does natural stone harbor bacteria?

If sealed and maintained properly, stone is extraordinarily resistant to bacteria. Many reports and studies are available online.


How much overhang can I have without supports?

For 1 ¼” <3CM> stone, we recommend supports with overhangs that are 12" or greater if minimum of 24” is already supported.


My marble and granite contractor is recommending that I choose a different stone. What should I do?

Usually your contractor will only recommend a different stone if the one you choose is unsuitable for your project ... too delicate or hard to work with.


Do I have to buy a whole slab?

No! We will determine how much material is needed for your countertops. NJ GRANITE do not charge you the price of full slabs. You pay for what is required to fabricate your tops.


What is kitchen backsplash?

The stones come from many countries all over the world. The primary countries are Italy, Brazil, India, China, Canada, Argentina, Madagascar, Greece and Norway.


What makes up the different colors?

There are a variety of factors that make up the color, pattern, and density of any given stone. The types of minerals and other impurities in the stone are big factors in the color hue of a material. The method of formation is a determining factor in the pattern and density, which ranges from igneous, meaning it was once molten and formed as it cooled, to sedimentary. Customers are welcome to visit one of our warehouses when making their color selection.


What is the difference between natural stone and quartz-based countertop material?

The difference between the two is that the quartz-based material is a man-made product. It is made from natural stone with a petroleum-based resin mixed in to hold it all together. Many manufacturers of these man-made products down sell the durability of natural stone and claim high maintenance being the cause. In fact, granite is primarily composed of feldspar and quartz, which is what these products are made from, but granite doesn’t have the resin in the mix. People generally select man-made products for colors that aren’t available in granite. The installed price between the two products is different, quartz being generally more expensive.


Why are some natural stones more expensive than others?

There are several factors which determine the price of each stone.

  • Costs of mining, some stones are located in hard to reach areas which increases the costs of it.
  • The cost of shipping, depending on where the stone is sent from, and also:
  • 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.
