Frequently Asked Questions

What is Granite?

Granite is an igneous rock composed mainly of minerals such as quartzite and feldspar. Minor amounts of other minerals such as mica will give it a sparkly appearance.

Other stones such as gneiss or schist are confused with granite but are not as hard. In geological terms, they are categorized as a metamorphic stone. Many popular stones such as Magma, Sedna, and Orion fall into this category.

Is Granite is hard to care for?

All granite countertops fabricated by American Marble & Granite are sealed prior to installation. Once installed, clean-up is simple with mild soap and water. For a specific granite cleaner, we recommend using Stonetech Revitalizer by DuPont. This will cut through grease and dirt while adding sealer back into your counters.

Where does Granite come from?

Granite is quarried in countries all over the world including Canada, Brazil, India, Africa and even the United States.

Where does Engineered Quartz come from?

Engineered Quartz slabs are manufactured using a process developed by Breton, an Italian company. This patented process combines approximately 93% ground quartz with polymer resins, colors and sometimes recycled materials. Numerous companies use this process for their own quartz slabs.

Do seams show?

Our seams are some of the tightest in the business due to the care we take to color match seams, machine the seams to remove imperfections, and blend the seams during fabrication. At the installation, our install team uses the best glues in the industry while taking great care to get the seams as flat as possible and create excellent glue colors.

Do I need an appointment for your showroom?

Our showroom is open Monday – Friday from 9:00 to 4:30 and Saturday from 10:00 – 1:00. An appointment is not necessary during these hours, but feel free to call ahead especially if you want to view particular slabs.

Do you work with local stone suppliers if I do not find what I want in your inventory?

We purchase slabs from all the wholesalers in the Portland metro and Seattle area. When you go to a warehouse to select a slab, let them know you are working with American Marble & Granite on your project so the proper holds are applied to your selections.

Can I use remnants for my project?

We highly recommend the use of remnants for smaller projects such as vanities, fireplace surrounds, or tables and desks. You are able to choose from our wide variety of granite and quartz materials.

American Marble & Granite offers a Cash ‘N Carry option which saves you the cost of measurement and installation. Simply bring us a template or an exact drawing and we will fabricate to your specifications. Once it is ready for pick-up, we will give you a call!
