Excellant work AGAIN

The boys did a great job. There was little trace that they were ever here. The clean up and workmanship was superb. Shem shows craftsmanship and dedication to all his work. He even came to us before making a design change that would benefit us and create a little more work for himself. Tri State stand out again as our preferred vendor.
