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.
