Great selection of tiles and countertops. For the exact same stone, they quoted us about 40% less than other places we checked. The staff were also very helpful, responsive, and easy to work with. Would definitely recommend!

We went in to inquire about countertops. None of the employees were interested in helping us especially the kitchen designer. We suggested to come in the next day and she told us not to because they are short staffed. She seemed careless and doesn't want our business and the only reason we went to them is because we did our bathroom few years ago. We will never go back.
Hi Karim, Thank you for sharing your feedback. We strive to provide the best possible service and am disappointed to hear about your experience in our showroom. We will review with our team to ensure this doesn’t happen again until in the future. Please feel free to reach out directly to me if you’d like to discuss this further or if there’s anything we can do to still assist you. Best Regards, Benson
We originally worked with Floorcraft to order cabinets and countertops for our kitchen remodel; however, Floorcraft went out of business and Cornerstone was willing to take on our project. Cat reviewed our design and remeasured our kitchen to verify correctness and accuracy. It was fortuitous that Cat helped us because she found and fixed several flaws that made for a seamless installation. She was also very responsive and her answers were thorough. We would highly recommend Cat for any future work.
I being doing Bussines with them since they have open the store and as a contractor always receive it on time and amazing customer service
We ordered cabinets for a kitchen renovation through Cornerstone and couldn't be happier with our experience. We worked with Cat, one of their designers, and she was amazing throughout the entire process from early design iterations through installation. Cat took our original concept, applied her knowledge to improve upon it, and was patient as we worked through different ideas. We used their local build line and the quality of the cabinets is great. During installation when our contractor (not affiliated with Cornerstone) made a few mistakes, Cat and the shop team were quick to help fix the parts, keeping our timeline on track. Thank you Cat and team!
Friendly staff and lots of products to choose from
What a great team to work with! We went with Cornerstone to help us with countertops in our kitchen remodel and we're so glad that we did. We worked with Albert who was awesome. He never pressured us into any decisions and helped us with a million questions. Once we finalized the countertop material they coordinated the installation which just wrapped up yesterday. The team they had to do the installation was unbelievable, true professionals. It was a 10/10 experience for us and I would highly recommend Cornerstone. The whole process took about a month from selecting the countertops to finally installation. We were actually the bottleneck in the process as we had to wait on a few cabinets to come in. Thanks again Cornerstone team (especially Albert) for such a great experience.
I called about a vanity I was interested in and Dan was awesome to work with. He helped so much. Answered all of my questions, and even presented me with other options since I am in a crunch for getting a vanity close to the one I was interested in. Definitely will be reaching out to them for future projects!
I think they have some great options and service is absolutely amazing. Pre fab counter tops is best for diy people
Literally worst service! Walked through the whole store, walked past 6 employees who where all staring at computer screens and not one person said hello or even offered to help!! Walked in and walked out like a ghost. How does this place make money if they just allowed a possible customer walk away. We will not be customers of this place!!
Hi Mayra, I’m sorry no one approached you to see how we could help. I’ve spoken to our team about this to make sure it doesn’t happen again. If you want to come back, I’d like to help you and if not, I appreciate the feedback and we’ll learn from this. Thanks, Benson
