"This company was fantastic to work with. They were able to take all my likes/dislikes and help me to find the perfect stone for my countertops. They had tons of different options and styles in stock to choose from so there is something for everyonesâ preferences. They were extremely time efficient in having someone come out for measurements and scheduling install. The install was extremely fast and extremely professional. The team worked quickly and the finished product looks absolutely amazing. They were great with all education for maintaining the stone once it was installed and were great in checking in with me to make sure everything was up to my expectations. I would highly recommend this company for any countertop installations."

"AGS was fantastic to work with, from Todd, the salesperson who came to my house, all the way to Luke who delivered a sink grid to replace the incorrect one I originally received. I had contacts with so many of the employees of AGS (Baris, Oscar, Baran, Tiffany, and more whose names I don’t remember) and each one was thoughtful, knowledgeable, helpful, and friendly. Their customer service is top-notch. I had a few minor glitches that were attended to immediately (e.g., the sink grid). I went to the showroom so I could actually pick out my granite stone. It was not a close ride but definitely worth it. The office staff and even the employees in the back with the stones could not have been more helpful. The "showroom" is really nice with lots of granite and quartz to choose from. I LOVE my new countertops, sinks, and faucet. I will definitely be recommending AGS to any of my friends who are in the market for new countertops."

"Extremely well, from initial response of owner, to timeframe for work completed. The gentleman who worked on the tub was courteous and professional. He took all steps necessary to protect the bathroom and the surface of the tub as he performed his job. The tub looks better than new! One word of warning for others, the fumes generated from this process are intense, so opening windows in the house while work is being done is highly recommended."

"I researched various types of kitchen countertops for a while, and chose quartz instead of granite because the prices were comparable, the color pattern was more consistent with quartz (without picking out a particular slab of granite), and I did not have to consider future resealing as a possibility. I also considered several different vendors and received estimates. Then I entered my request online with Origins Granite, which was recommended by others on Angie's List, and immediately received a call from them. They sent a representative to my home that brought various samples. I decided to use them because the price they quoted me was all-inclusive and better than previous estimates, including all the plumbing work, new sink and edge cuts that cost extra with other vendors. The only thing that I had to purchase separately was the faucet; they used the model number to fabricate the holes needed in the countertop. About one week after signing the contract, they called to say my color choice had become unavailable. They presented three other choices but recommended one of the three as the closest to my original choice. I agreed and immediately realized from my previous research that it was from a more expensive manufacturer. They assured me that my original price quote would not change. They took care of everything: measurements were taken and installation was completed on the date I originally requested. I am very happy with the outcome; it is a great match for my kitchen. All of the people I dealt with at the office and in my home were very accommodating, courteous and professional. I would highly recommend this company to others.

Stone Countertops FAQs, answered by experts

Quartz countertops are not recommended for outdoor use. While durable indoors, they are not designed to withstand outdoor conditions like sunlight, weather, and high heat from barbeque grills. Exposure to these elements, particularly UV rays, can cause the resins in the quartz to break down, leading to discoloration and damage to the surface. For a longer-lasting outdoor countertop, it is better to choose a natural stone like granite, which has greater resistance to these elements.

The cost to install a kitchen island ranges from $900 to $6,500, with an average price of around $4,800. The final cost depends on whether you buy a prefabricated unit or have one custom-built. Prefabricated kitchen islands are generally cheaper. A simple prefabricated cart can cost between $150 and $900, while a permanent, stationary prefabricated island costs from $900 to $5,000. A custom-built kitchen island averages around $4,800 but can cost $10,000 or more depending on factors like materials, size, design complexity, and accessibility.

Silestone® is a brand of quartz countertops; one isn’t necessarily better, but they have their differences. Silestone® costs slightly more than the average quartz countertop because you’re paying for the brand name and unique features. For example, Silestone® is often more sustainable than regular quartz because you can purchase varieties made with recycled materials. It also has antibacterial properties and design options some homeowners prefer. Plus, you can use it across your whole kitchen rather than solely for countertops.

Granite is one of the most popular options for countertops, and most homeowners believe that granite countertops are worth the money. Granite is more affordable than marble and quartz, and provides outstanding durability and longevity. Granite countertops are also desirable because they are entirely unique; unlike some other countertop materials, your granite slab won’t be identical to any others. Granite is porous, which means it has the potential to stain if you don’t clean up spills quickly, but the general durability and relatively low cost make it well worth the investment.

Onyx countertops have pros and cons. If you seal it properly and take care not to damage it, it can make a good countertop surface. However, it's more often used in bathrooms, where it’s less likely to sustain damage. Having an onyx kitchen countertop is possible, but you’ll need to take extra care not to burn, stain, or otherwise damage the material.
