We were very happy with the service, workmanship and product from Cornerstone. We hit a couple snafus along the way, and Aaron was calm, super helpful and made it all come together. They did a great job, definitely recommend them!

We work with Aaron and his crew for all our projects and recommend him to others whenever someone is in the market for surfaces! He is top notch to work with and our clients sing his praises as well. Their showroom and staff are amazing at what they do and are so knowledgeable and helpful to our clients and ourselves with every interaction. It’s wonderful when you can find a subcontractor of Aaron’s caliber to work with over and over again. Thank you Aaron and crew!

Found this company last month for our house counter tops. Aaron and the crew are all super nice and friendly people. I Would HIGHLY recommend this business over Lowes or Homedepot any day.They not only got the job done much faster than the other two but they are also a local business that I was happy to support.They have very nice quality counter tops and their showroom is very clean and professional.I would be definitely using them again in the future if I ever need any other countertops made.Extremely happy with the results.

Cornerstone Custom Granite is a professional and reliable team to work with. They were on time and finished when they said they would. Our granite was cut and installed to perfection. We highly recommend them to anyone wanting quality granite countertops.

We used Cornerstone for our kitchen remodel and they did a fantastic job! When we decided what color and pattern we wanted Aaron sent us several photos of the available slabs to choose from. Once we chose the one we liked Aaron had it shipped to his shop right away. Aaron was great to work with and went out of his way to meet our aggressive schedule. The countertop is perfect and beautiful and the price was very reasonable.

Aaron did an excellent job on our project. He came highly recommended, and didnt disappoint! He was professional, responsive, and did a quality job. It was a pleasure to do business with Cornerstone Custom Granite and with Aaron.

For our kitchen remodel including complete quartz counter tops in several areas we sought out three local companies for competitive bids and quartz/granite choices. The first Company was the original installer when the house was built in 2008 . The second Company was one we had previously used in our Leavenworth house . The last Company was Cornerstone granite, a Company from Cashmere that had good local reviews. Our final selection for the quartz install was Cornerstone . At Cornerstone, you meet with the owner who is also the installer, demo person, counter top measurement person and contractor. The bid arrived when promised and was competitive. The original installer also had a timely bid while the previous Company used in our house in Leavenworth took several weeks. Their bid actually arrived during demo from Cornerstone . The bid from Cornerstone was fair, concise and broken out detailing each cost item as was the date for work completion. Aaron completed a template and a deposit was made with a promise of single day demo, haul away and install. The day arrived and Aaron, Josh and Stanly ( without an e) arrived . There was no standing around, no breaks and just a very quick and short lunch taken . Demo was quick and clean with our floors protected and demo ganite hauled out to the waiting trailer. Counter top stove was protected and removed along with faucet and discarded sink . Install went smoothly which each of the three tasked with various work assignments. There was good communication throughout the process as the remodel was occurring . We could not be happier with Aaron the owner and the final product . Josh, a finish carpenter by trade was excellent in cutting in the trim . All in all, we are 100% satisfied at all levels and highly recommend Cornerstone for you next project .

I highly recommend Aaron and his crew. I had them install two bathroom countertops and one laundry room countertop. I really wish I used them for my kitchen countertops which were installed two years previously from another company in the valley.

Beautiful work and thoughtful planning to the design of our new kitchen counters. Highly recommend.
