They have anything that you could possibly need for your project. This is a one stop business. The guys working the yard take care of business quickly. Great place.

This establishment is a mad house . Avoid it at all costs. I went there a few days ago All the guys inside at the sales counter are rude, unprofessional, nasty, condescending, and had no manners they were all burping while “helping” customers! and they all seem to be Drinking way too much coffee or something else. Never in my life have I seen such a dysfunctional place of business. I felt bad for the poor girl behind the counter they all seemed to be picking on her for being new. I came in for a couple bags of polymeric sand because it was close to my house but I should’ve went to big apple

We needed some fine sand to put under our above ground pool. This place was able to take care of us no problem.

Not helpful. Staff dismissive. Asked a simple question and answered back with absolute rude and useless answer. Customer in store instead was way more helpful than the employees here. Avoid this place unless you are ready to get dismissed

Worst customer service I've ever experienced as a building professional. As an Architect, I'm completely comfortable with gruffness or people being short on the phone, but can usually at least expect professionalism, maybe a returned phone call or answered email. I wasted about 8 billable hours, including a trip out to their yard in an attempt to cut through the poor communication, trying to get an order fulfilled that I eventually had to just give up on. Speaking to them face to face was even worse than the experience on the phone and email!
I will never try to source stone for a client or project

Great prices. Not really set up for Consumers. this is more for a professional landscaper and construction.

One of the worst customer service experience. One day I called regarding block curbs and they put me on hold while I was explaining to them that we needed A LOT of it. Then rudely told me that they needed to call me back because they're "dealing" with other customers. I thought okay they must be busy and took down my information. Never received a call back, so I call them back and they did the same thing again with me. I just hung up and called another place. Glad I did because I found a place that had respect and cheaper price for customers.
