Great place to get all kinds of stone products for your home project/renovations. The prices are very reasonable. It's a pick your own and must have a heavy vehicle to transport. Or you can have it delivered. I have done varies projects from stone from Tri-State and they all have turned out great.

Had a good experience. Guy on the phone helped me get the right aggregate for my project and scheduled delivery. Guy who delivered materials was a little earlier than I was planning on but did an awesome job putting my stone right where I needed it through by masterful driving through the back alley. I barely had to move it to its final place. Overall, satisfied and will return for future aggregate/stone needs.

I really wish there was some attempt at signs to identify/price the products and perhaps some guys wandering around offering to help move stones around. Other than that, it was fine.

Love this place. As a DIY-er, it's a little intimidating to go for the first time (see Mike Coogan's post for advice). But everyone I've dealt with has been super professional, great service. It's become a treat to get to visit my favorite quarry. Deliveries have always been super prompt, often within a day or two.
