The BEST. Highly Recommend! The crew was professional, nice, responsive and easy to work with - nothing was a problem! Our bluestone and limestone looks better than it did when it was installed!

Cornerstone did a truly incredible job of repairing, sealing, and rejuvenating our 32 year old concrete tile patio, balustrades, stairs, and pool decking. Its employees are expert, professional, courteous, and efficient. The company charged exactly the same amount as set forth in the original estimate. I have no doubt that Cornerstone is the best in the business.
