Not only were they terrific on scheduling and pricing, it was very clear that they take a great deal of pride in the quality of their work. They did a great installation, and finished everything beautifully. And they're really nice people, too.

Review by Shedrick B. in Valley Stream, NY
Project: Install Stone Slab Countertops
Jessu and the cornerstone contractors were superb! They were not only dependable,reliable,and professional,they were also accomodating and determined to make sure the job was done to our satisfaction. Whenever we called upon them to question anything we were greeted with kindness and the reassurance that everything would be done according to our specifications-and it was! It was extremely important to us that this job be completed before Thanksgiving as we were expecting a big family crowd. Jessu promised to deliver and he did! As a result I've given his name to both family and friends. I love my kitchen! Cornerstone you're the best! Diane B.
