Granite Countertop FAQs

Here you will find some of the most frequently asked questions we receive about granite countertops. For more specific questions, please contact us today! 

  • Where is your service area?

    We have two locations in the Chicago area: Geneva and Barrington. We work with customers throughout the Chicago area as well as Northern Illinois. View our areas served page for a full list of towns we serve.

  • What is the difference between a slab and a remnant?

    Slabs are full pieces of stone that are best suited to large scale projects or projects requiring a great deal of custom work. We fabricate slabs in marble, granite, quartz, onyx, soapstone, limestone and travertine. Remnants are leftover pieces from a full slab, varying in size from very small to large enough for a countertop. Remnant inventory changes constantly, so we recommend that you call or visit one of our locations to view the current selection. 

    What is vein matching? 

    One of the most appealing aspects of natural stone is veining, or the lines that run through a slab. In order to ensure that your slab has a consistent vein scheme, MGT offers vein matching services. We are able to provide a virtual layout of your slab before we cut it, ensuring that it is placed exactly how you want it. 

  • How messy will this project be?

    As with any construction, replacing countertops will create dust. We try to keep the dust to a minimum but I would personally remove the drawers and clean out the cabinets before we install the tops. We recommend commencing on any painting projects after the granite is installed.

  • How important is it to view my slab or layout?

    Usually, I would say it is very important to view your granite prior to our cutting and fabricating. Since granite is a natural product, some parts of it will vary or be a different color than the sample. At your request, we can email a layout prior to fabrication or you can come in to layout the slab with our CAD expert in person (no extra charge!)

  • What if my granite chips?

    Granite is made up of many different types of rock that have been compressed over time. Some small pieces may chip out of the stone, especially around the sink or edges. Because the color goes all the way through, they are rarely noticeable but if you have a spot that bothers you, we can fill the area with a matching epoxy. Chips caused by normal wear and tear (not dropping a cast-iron skillet on it) are covered free of charge and completed when we are in your area for another install. Save any material that does chip as we may be able to salvage it.

  • Does granite harbor bacteria?

    Generally speaking, bacteria grows in warm, moist, dark places. Granite is cool and dry. Bacteria is more likely to grow in formica tops because they have a particle board sub-base, especially with the moisture from a dishwasher constantly getting trapped.

  • Does granite need to be sealed every year?

    Granite cleans very easily with warm water and a soft cloth. MGT Stone seals the countertops at the factory with a premium sealer, so you will not need to re-apply sealer for several years.

    Isn’t there radon in granite?

    Radon occurs naturally in many products, including granite; it also occurs in sand, concrete, soil, natural gas, ceramic plates, glass, clay bricks, well water, etc. Generally speaking, the levels of radon in household building materials, including granite, is relatively low, especially considering the amount of air in the home. Often times, the level of radon even with granite in the home is higher outside the house than inside. For more information, please visit the radon website:

  • Does granite stain?

    If oil is left on the countertop for an extended period of time it will stain the affected area. Acidic solutions ranging from fruit juices to cleaners can etch the surface if applied for prolonged periods of time, even after sealer is applied. Granite is a natural stone and under normal circumstance and daily use the sealer will inhibit stains from happening in indoor applications but any prolonged exposure to oils, acids or chemicals may result in staining in that area.
