We stock the following sizes:

  • 96”-118” x 26” standard
  • 96”-118” x 36” peninsula
  • 96”-118” x 42” peninsula

All of our slabs have a 1.5 inch industry standard rounded bullnose on the front (Bullnoses are the rounded edges of counters). Depending on installation location, your slab may have a left, and/or right bullnose.


Quarried natural stone by nature have conditions that cannot be controlled (e.g. color, size, veining, fissures, thickness, etc).

As a consumer/contractor, you may not understand some of the conditions inherent in natural stone. As a result, we must have a signed disclaimer attached to all selections requesting any natural stone products, to avoid future problems or misunderstandings.

Granite, marble, limestone, travertine and any quarried products we carry have been cut from carefully selected stone blocks produced by Mother Earth.

As a natural stone product, please understand that some stones may contain naturally occurring imperfections, which are characteristic to the individual stone. These characteristics include: color and shade variations, geological flaws, irregular markings, voids, veins, fissures, cracks, lines and/or minor separations.

It is a standard practice by the manufacturer or fabricator to repair these separations by one or more of the following methods: waxing, filing. All of these variations and characteristics are common and present to some degree.

When granite or marble is installed, the various sections will be joined together with seams. Seams are small but might be visible, and are typically filled with a color-coordinated polyester adhesive or epoxy to minimize their appearance. The location and quantity of seams are determined by the fabricator according to slab sizes, sink and cook-top cutouts, project design and jobsite access. A typical job will have 2-3 seams. They are commonly located in the center of cutouts like sinks and cooktops, at inside corners running the depth of the countertop, and in backsplashes at any height or elevation change.

To polish or not to polish seams, that is the question. Customers will typically have the option to choose. An unpolished seam will feel rough, but the texture of the seam will be like the rest of the counter. A polished seam is smooth, but when viewed from side angles will most likely be a different color compared to the rest of the surface. Customers must select and acknowledge which option they prefer. If the appearances of seams are a concern, please see our showrooms for a demonstration.

No stone product will be purchased or installed without a signed disclaimer from the homeowner or the builder representative, accompanied by the appropriate color selection.

It is hereby understood that GS Granite Cabinet Expo Inc. will not be held responsible for the natural conditions of the stone products as described herein.

The Process

After getting an idea of what you want, come on over to our showroom! You will be able to get a closer view and talk with our knowledgeable staff, or check out the other remodeling services we offer.

After the free in-house measurements and price quotes, we will discuss our work schedule and predicted cost, and show our predicted 3D models. We are always open to input from the customer, and the time of the project varies with your selection. A countertop installation normally takes less than a week, but a full kitchen remodel with countertops and cabinets can take anywhere from 2 weeks to a month. Please inform us if you have time constraints.

Here are some examples of the 3D walkthroughs we create for you, with the kitchen and bath design software, 20-20.

After Installation

In order to keep your stone countertop in top condition, here are a few basic tips (but you can always ask us for more).

preventing damage

Granite is very durable. If it can survive the fabrication process without damage, it is very difficult to break it. To avoid having problems with your stone material, be sure to follow the guidelines here to prevent any permanent damage.

  • Avoid prolonged exposure of your granite surface to strong chemicals, such as paint removers, oven cleaners, acids, and oil. If contact occurs, quickly wipe or absorb with a towel.
  • Do not cut directly on your stone countertop. This can cause deep and permanent scratches to appear. Instead cut on a cutting board that is placed on top of the stone.
  • To prevent staining, we recommend that you re-seal your countertops every 9 months to a year.
  • Avoid directly dropping heavy or sharp objects on your countertops.

cleaning and sealing

Your stone countertops are very easy to clean. Common household products will keep your stone looking beautiful for a long time.

Recommended Cleaners and Sealers

  • Hot, soapy water
  • Any water-based sealant (we personally use Glaze ‘N Seal, and carry it in our store)


1. What is granite?

Granite is volcanic (or igneous) rock. When molten material from the Earth's core, called "magma", comes up to just beneath the Earth's surface and solidifies under tremendous pressure, it becomes granite. Granite is very hard and extremely durable. It has a granular structure and consists mostly of quartz and feldspars accompanied by one or more dark minerals.

2. What can granite be use for

Due to granite's high density, low absorption rate, scratches, heat and acid resistance, granite can be used for a wide range of applications, including flooring, fireplaces, furniture and countertops. One of the leading uses of granite is for kitchen countertops. With many beautiful colors and patterns available, granite will fit with any kitchen design.

3. Will there be color variations in my granite?

Yes, as with any stone, naturally occurring variations in color and texture should be expected. These variations and contrasts are what gives granite its depth and beauty and set it apart from other man-made products. They can include color and shade variations, geological flaws, irregular markings, voids, veins, fissures and lines of minor separations. In most cases, slabs are cut and bundled consecutively from the same block of stone so as to keep variations as coordinated as possible.

4. Will I see seams in my granite countertops?

Yes, granite is a stone, and because of this, seams cannot be "melted" together. Seams are normally filled with a color-coordinated polyester adhesive or epoxy to minimize their appearance. The location and quantity of seams will depend on slab sizes, sink and cooktop cutouts, project design and jobsite access. If the appearances of seams are a concern, please ask to see a sample of a typical seam.

5. How should I maintain my granite countertops?

You must seal the granite 4 days after the installation. It is recommended you reseal your granite every 9 months to 12 months. Sealant and silk steel wool are available at our showroom. This will help prevent staining from liquids that are spilled on the surface. Avoid prolonged contact with staining agents such as cooking oils, juices, acids, ink, etc. A non-abrasive neutral cleaner, such as soapy water, should be used for normal maintenance. With a little care, granite can give you a lifetime of service.
