We used their stack stone for our South Carolina home and loved it so much we ordered the same stone for our Florida home! The quality is amazing and everyone is so nice and always willing to help. They make ordering easy!
Thank you so much for all of your help!
Mountain View Stone was one of the very best partners we worked with in building our home. Their product, customer service and communication were simply outstanding. They delivered on their word and their product even when we moved up a time line unexpectedly. They beat all the competition pricing on better quality products that they personally manufacture on site. Communication with Carl was excellent as we navigated challenging building delays. He was patient, professional and offered valuable guidance with our order from the styles, accessories and quantities. Mountain View Stone will be our partner for any future stone work we have. Thank you so much to everyone that made our experience so seamless!
I received the samples and they looked great! Much heavier than I expected too which was good.
Thanks again, you have been great to work with.
It went great! The stone was not hard to apply and my son and I did it over the course of a couple of weekends. Thanks for everything!
Thank you very much for all of your help!
