Granite Tops - Granite Tips & Choices

Granite is an igneous rock, formed from magma deep within the earth. Granite gets its unique look from crystals of quartz, mica, feldspar and other minerals trapped within the rock. Each piece is unique.
Granite is a popular choice for countertops because of its rich, deep colors and many variations. It's a tough, durable stone that requires little maintenance.

Colors and Finishes

1. There are more than 1,000 varieties of granite colors and textures. Colors include white, cream, pink, yellow, red, blue, green, gray and black.
   There are two types of granite styles to consider when choosing countertops. "Consistent" granite has the same pattern throughout each piece. "Variegated" granite has veins that vary from piece to piece. They're attractive, but the veins make it more difficult to match sections.
   You can choose between a flat finish, which is quite smooth but more open to staining, or a polished finish, which is glossier and more durable.

Granite Warehouses

2. It's tough to choose granite from a small sample. Colors can vary within large pieces. And a color that looks attractive in a four-inch sample might be overwhelming in a six-foot countertop. Your best bet is to visit a granite warehouse, where you can view large slabs. Consider bringing samples of your flooring, paint and cabinets with you.
   After you choose your granite, ask to see four or five slabs for comparison. Each is unique, and though the general color may be the same, you may prefer one pattern variation to another.

Cost

3. Granite ranges from $30 to $300 per square foot and up. It will vary according to square footage, number of cuts and labor costs, and you also need to factor in edging and backsplash pieces. Remember that while the granite can't have a warranty placed on it, your installer can warranty the installation.

Care

4. On a daily basis, you simply wipe down the granite with paper towel and soapy water. Never use abrasive cleaning products.
   Once a year, use a penetrating sealer to maintain the finish.
   Don't let foods with high acid content, like lemon juice or vinegar, remain on the counter's surface for any length of time. Acids can mar the finish.

What about radon?

5. Because granite is a naturally occurring igneous rock, it can contain concentrations of uranium that produce radon gas,. According to the Environmental Protection Agency, however, there is not enough data "to conclude that the types of granite commonly used in countertops are significantly increasing indoor radon levels. Some granite may emit gamma radiation above typical background levels. While radiation levels are not typically high, measurement of specific samples may reveal higher than expected levels on a case-by-case basis."
   If you are worried about raised radon levels, you can buy an in-home test kit at retail stores for about $25. If the radon level is high (4 pCi/L of air or higher), go to www.epa.gov/radon/radontest.html for assistance. The site also tells you where to find the kits.
