The very first job I had for Tri State Stone was for 385 units at a condominium property. Since then, I have added about 114 and will do about 600 units more. So far, they are done with 1/3 of the units. Their performance is tremendous; they are very on top of schedule and exceeded my expectations. The quality of their products is good, and it is also nice dealing with them. I had dealt with other companies before, but they could not handle the work load as I wanted. I highly recommend them!
