Tri-State Stone & Building Supply Inc. 8200 Seven Locks Road, Bethesda, MD 20817

"Amazing customer service both in person and on the phone. They walked me through my options and suggested ways to economize. My gravel was delivered basically immediately. Strong recommendation."

"I discovered Tri State 3 years ago when I was planning a new, larger patio. I'd gone to NOVA Stone and liked their limestone, but the price was off-putting. There was a large hardscape project close by, and I ended up talking to the crew chief. He recommended TriState. TriState's price was about 60% of NOVA's, and it was in stock. Today I bought more of the same 18x36 stone (1.5" thick), but the price has literally doubled. Not happy about that, but I've been waiting for their resupply for a few months. We're connecting the original patio to our new garage. Jake, my original rep, recognized me immediately and showed me the 2 pallets that had just arrived. I bought all they had. Since it's "variable", you can't select pieces. There were probably 10 pieces quite different than the rest, but there were an extra 6 pieces that looked great. After initially deciding I didn't need them, I want the best look, so I called back to change the invoice."

"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."

"Really a great place to get stones, cement block, gravel, and brick. No frills yard with great customer service. Do not expect a full service concierge type place. This isn’t it. Drive in, load your own stuff, pay and take off. Great prices and much better than a hardware or home improvement store. I will definitely be back."
