In 2019 my wife and I found Cornerstone in hopes of redoing a horrible installation from a different company. Cornerstone was able to measure, fabricate, and install the new countertops in a matter of 3 weeks. The original company took 3 months. Working with Andre was absolutely amazing and the quality of the counter tops was superb.

Cornerstone did a fantastic job from the very beginning. The estimating, field measuring, and installation all went flawlessly. The staff are friendly, knowledgeable, and professional. I love my new soapstone countertops and would hire them again anytime.

When we were looking for a fabricator to help with a renovation project, we got several quotes and Cornerstone was by far the most competitive (by a long shot, really). We knew our project could be challenging as we wanted something quite specific, but Cornerstone was confident they could make it work. We worked with Karina, who was extremely knowledgeable, kind, and quick to respond. When we had issues with a supplier trying to sell us a damaged piece, Karina was quick to answer questions and worked to find an alternative supplier that a) didn't significantly change our quoted price and b) had what we were looking for.
While other companies took days to respond and schedule, Karina took just hours and got us on the books right away. At the end of the day, our project turned out exactly how we hoped! We're thrilled with the work and the experience with Cornerstone, and can't recommend them enough.

I highly recommend Cornerstone Granite. As a professional property manager, I work with many vendors. Cornerstone provided a perfect solution for my two bathroom counters (marble remnant). They were professional, punctual and precise.

I would recommend this place for your countertop needs. The front office staff ( Perla, Gaby and others ) were helpful and provided prompt and clear information. The installation crew was on time and the crew ( especially Chuy) worked with dedication to get the waterfall edges to look great. The owner Andre provides excellent customer service and came out himself to fix a few blemishes the next day. Overall I am satisfied!
