Seibert and Smith Contracting offers a diverse selection of natural stones that can be applied to countertops, thresholds, showers, shower seats, outdoor kitchens, floors and more! From Travertine Stone and Slate to Marble, Granite, and Quartz. We carry it all!


photo 3333Our fabricating plant is located in Northern Jersey where the slabs are cut and and polished and then delivered to the job site. At which point professionals carefully install them and finish drilling any sink, faucets or other plumbing fixture holes. Granite is available in a wide variety of colors and variations, as well as unique veins and patterns.

Choosing natural stone for your Granite counter tops has several considerations to keep in mind. Some Granites without color variations could be selected from very small samples. Others need to be viewed fully because of slight shade variations. Although variations give Granite its natural beauty these same variations could cause disenchantment if you’re looking for something that is going to be exactly the same throughout every piece. Before making a final selection on natural stone, be prepared to accept its earthly beauty along with its natural variance.

Granite’s durability, longevity, and economy make it ideal for kitchen countertops and other heavily used surfaces, including table tops and floors. Various different profile edges are available for no additional cost as well as a few more labor intensive edges such as the full bullnose, ogee, and double ogee at a reasonable cost. We have numerous samples of Granite, Marble and Quartz in various price levels available in our stone yard to be seen on site at our showroom. We can also arrange to have full slabs viewed at our fabricating plant.

PLEASE NOTE: Granite slabs are approximately 108″-128″ long and 56″-72″ high by 1 1/4″ thick (3cm+-.) Counter top parts that are bigger than this must be seamed. The average kitchen counter top has one or more seams. A colored epoxy or silicone is normally used to fill counter top seams but because of Granite’s natural shade variations the seams are not always 100% invisible.

Granite is one of the hardest naturally occurring stones in the world. Because it is far less porous and has more aesthetic qualities than Marble and Limestone it is a smart investment when used as a kitchen or bathroom countertop. Granite’s hard surface and low porosity make etching, scratching, cracking and staining the material unlikely (although there are always exceptions to any rule!) By definition, Granite is an igneous rock comprised of at least 20% quartz and up to 65% alkali feldspar by volume.

Granite is usually found in the continental plates of the Earth’s crust and sometimes found in circular depressions surrounded by a range of hills. Most of the Earth’s Granite was formed during the Precambrian age and it is the most commonly found basement rock sitting below the thin sedimentary crust of the Earth.

In recent years the machinery required to cut this hard rock has become more affordable and available thus leading to an increase in commercial and residential use for the stone in the construction and remodeling industry. Homeowners looking to sell in the future are updating their outdated countertops to Granite as a key selling point.

Marble, on the other hand, is much softer than Granite and is not recommended for kitchens and heavily used surfaces. Marble is actually a non- foliated metamorphic rock made up of calcite, dolomite or serpentine. There are not any large differences between Marble and Limestone because Marble is actually metamorphosed Limestone! The color variations and veins found in Marble occur due to mineral impurities such as silt, clay, iron oxides, et cetera. Marble is predominately exported from four leading countries; Italy, China, India and Spain but is also found in the UK, U.S., Ireland, Greece, Russia, Romania, Sweden and Germany.

Marble and Limestone’s softer more porous composition makes it a more sensible choice for walls and pillars inside or outside of buildings. It’s relative isotropy and homogeneity, and  relativewinstead with travertine (2) resistance to shattering have made Marble and Limestone a preferred material for sculptures throughout history.

Quartz is one of the hardest minerals on the planet and is resistant scratches, heat, stains and water. Quartz countertops are manufactured using Quartz minerals combined with high quality polymer resins. This allows for a Quartz countertop to be a solid pattern or color all throughout the slabs. Similar to Granite, you choose from various stone profile edges and after your stone selection is made, our fabricators come out and install the slabs, drilling plumbing fixtures holes on site. The price range for Quartz is relatively close to Granite, and the only significant difference is Granite is polished naturally the was it was formed in the Earth and Quartz is manufactured from natural materials into a man made pattern or color.

Travertine, a type of Limestone, can be left in its natural state, with no polishing. It is sedimentary rock formed from the remains of plants and animals, often deposited by mineral springs and hot springs. We often find seashell fossils on Travertine tiles. It is natural Calcium Carbonate (CaCO3) and varies in hardness. The Romans mined deposits of Travertine for building temples, aqueducts, monuments, bath complexes, and amphitheaters such as the Colosseum, the largest building in the world constructed mostly of Travertine.

Travertine is one of several natural stones that are used for paving patios and garden paths. It is sometimes known as Travertine Limestone and as Travertine Marble, and is characterized by pitted holes in its surface. It comes in a variety of colors from cream to grey to coral-red. The natural shades of Travertine ranges from soft ivory and pale creamy white to rich golden shades of walnut and honey, silvery greens, rustic reds, and deep mocha coffee shades. Since Travertine is natural stone and the colors depend on local mineral and organic materials, the tiles are never a single solid color, although some Travertine varieties are more consistent in color. Colors in each tile will vary with mottling and veins or bands of contrasting color throughout the stone. Each stone has unique character, although stones quarried from the same area will have enough overall similarity to create beautiful floors, walls and decks.

Therefore, putting Travertine in a kitchen or heavily used bathroom is not a good idea. Travertine should only be cleaned with a neutral or mild alkaline-based cleaner. It is also porous with many visible holes, often filled with same-colored epoxy to give it a smooth appearance.

Travertine can be used for countertops but it’s not recommended. It is easily scratched and etched by certain food products. It works well for flooring, accessories and smaller spaces. This stone seems to open up small areas and makes them feel more spacious and airy. The surface finishes for Travertine stone vary. Not all Travertines are capable of the polished high gloss finish – only the harder types. This stone will never achieve the same glossy finish as Marble and Granite.

Travertine can have four major finishes: polished (shiny), honed (matte), brushed and tumbled (textured surfaces). The type of finish given to the Travertine will determine how shiny the surface will be. The most common finish for Travertine is honed.

PLEASE NOTE: Travertine should be sealed with a penetrating sealer to prevent staining and reduce soiling.

Slate on the other hand is more durable than Travertine. Slate is found naturally occurring in large quantities all over the world! This makes it a cost effective material that can be used in roofing, tile and countertops. It has a unique leveled feel to it that makes it a no- slip surface to walk on in or outside your home.

Slate is a water resistant material that does not deteriorate over time when exposed to moisture. That is why Slate is often found out of doors surrounding hot tubs and pools or just simply applied as a nice outdoor patio. Foyers, kitchens and bathrooms are also a good place to lay Slate tile due to its durability to high traffic and water resistance.

Slate is composed of clay or volcanic ash exposed to a strong compression causing fine grained clay flakes to regrow in planes perpendicular to the compression. When professionally cut by striking parallel to the foliation, with a specialized tool in the quarry, most Slates will create smooth flat sheets of stone which have been used for roofing, floor tiles and other purposes for many generations.

Slate is available in various colors ranging from shades of brown, black and grey and work best when applied to heavy traffic areas of homes and businesses or on roofs.
