Frequently Asked Questions


NW Granite Creations strives for excellent quality, efficiency and communication. Therefore, in an effort to make the kitchen renovation project as smooth as possible, NW Granite Creations has provided questions and answers typically asked before commencement, during and after the project.


What kinds of finishes are available in natural stone?

Marbles and granite are typically shipped from quarries with a polished, or shiny, face. Limestone's are usually available in a “honed” finish, which is smooth to the touch, but not shiny. Limestone's can, however, also come in tumbled or distressed textures depending on current availability. If you’d like a more natural finish, but do not want to use limestone for your project, we can remove the polish on any marble or granite to give it a honed finish.



What kinds of edge details are available?

We can do any kind of edge detail that you can imagine... from the simplest straight polished edge to an elaborately detailed edge. Our most popular edges are straight, crescent, half bull-nose, and full bull-nose.



What thicknesses are available in natural stone?

Granite slabs are available in two thicknesses; 2cm and 3cm. Marble and limestone slabs are readily available in 2cm and 3cm depending on color selection and current availability. If a thicker look is desired we can laminate, or glue, several slabs of stone together until the desired thickness is obtained. Granite, marble and limestone tiles are typically 3/8” thick. For custom bathroom projects relating to tub surrounds and shower stalls, NW Granite Creations offers 6mm-8mm Granite or Marble Panels. Material available only through NW Granite Creations in the Pacific Northwest.



What is the difference between an “ under-mount” sink and a top-mount sink? Is there a cost difference for the type of cutout required?

top-mount sink has a lip that folds over the counter top. The sink rests on top of the cutout. An under-mount sink rests below the granite/marble material so that a polished edge of granite, marble, etc. is exposed above the sink. An under mount sink cutout requires more polishing and installation labor than a drop-in sink cutout, hence an under-mount is more costly than a top mount.



How heavy is granite or marble and will my cabinets support it?

Granite and marble are roughly 6 pounds per square foot per centimeter of thickness. For example, a 2cm slab of granite weighs approximately 12 pounds per square foot and a 3cm slab weighs approximately 18 pounds per square foot. Any cabinet that is well constructed and properly set will support the weight of natural stone counter tops. Dura-Thin weighs approximately 4.5 pounds per square foot. Ideal for tub surrounds, shower stalls, aboard yachts and various other custom projects requiring light hard stone material.


Do I need support brackets for my raised bar or overhang?

We recommend using support brackets for any granite or marble overhang that exceeds 10” and require brackets for overhangs 12” or wider. The length of the brackets should be roughly 3” less than the total overhang width and should be placed approximately every 3 or 4 feet.


Can my plumber use “plumber’s putty” on my stonework to adhere the sinks and faucets?

Absolutely NOT! Plumber’s putty can quickly ruin natural stone tops, as stated on the back of the package. Your plumber should use 100% silicone in place of plumber’s putty.



Do I need to “seal” my stonework?

We seal all slab-work, i.e. countertops, tabletops, fireplace surrounds, etc., prior to installation with an impregnator sealer. This sealer soaks into the stone to help guard against staining and does not change the appearance of the stone. The sealer needs to be reapplied every three to five years through a very simple process. 


Will my countertops have visible seams?

Depending on your cabinet layout, your tops can potentially have visible seams due to size limitations of material. We try to put the seams in the least conspicuous areas and will be happy to discuss them with you prior to fabrication. However, depending on the material color there is a chance the seam will be appear invisible. Moreover, most seams are done at the sink line.



Does granite require special care?

Marble and granite are easier to maintain than you might expect. Warm water, mild dish washing liquid and a soft cloth clean up most spills on both surfaces. Granite is a worry-free surface, requiring few special precautions. It is extremely durable, stain-resistant and easy to care for. Hot pots and pans won’t damage it. It won’t chip, crack or scratch under normal use. Cutting boards are recommended when slicing bread, meats or vegetables to protect your knives from becoming dull.



Does marble require special care?

Marble and granite are easier to maintain than you might expect. Warm water, mild dish washing liquid and a soft cloth clean up most spills on both surfaces. Marble isn't quite as worry-free as granite. It has a softer, less stain-resistant surface than granite and it should be treated like a fine piece of wood. Spills should be wiped up immediately; coasters should be placed under beverage glasses to avoid staining and etching. Marble is especially susceptible to damage from citric acids, alcohols and oils. Yet, with proper care, its beauty will last for generations.



What is the total cost per square or linear foot?

We do not price per square or linear foot. We approach all of our work on a completely custom basis, including our pricing. Please contact us for an estimate on your specific project. We generally turn around pricing within 24 hours. And we provide written, detailed estimates for all our work.



Generally, how does the cost compare to other surfaces?

Initially, marble and granite cost about the same as solid surfaces, but the price must be weighed against performance. Marble and granite are far more valuable than synthetics in much the same way that diamonds are more valuable than rhinestones. The depth and character of natural stone cannot be matched by any man-made surface. Natural stone does not depreciate with time and adds value to your home.



My project is a remodel. Will NWGC remove my existing countertop?

Not generally, NWGC prefers that existing counter tops be removed by a licensed handyman. All tear out of existing tops ideally should be completed prior to taking our measurements to ensure a more exact fit of tops. At the very least, existing tops must be removed prior to installation of new tops.



What is your lead-time for installation?

Our lead-time is no more than five days from the initial template depending on the size and complexity of the project. Most often, projects are completed within 3-4 days. Example: template on Monday and install on Wednesday/Thursday.



At what point can you start the template on my project?

All measurements for counter tops must be taken after all relevant cabinets are in place, leveled, and in their final lo cations. All appliances need to be on location, and the sink needs to be purchased and on hand.
