Great experience every time I have been there. They are always busy, but make the time to help. Michelle took the time to walk me around and show me the different paver options and even put my order on 3 different skids so I didn’t overload my truck. Great customer service!

Awesome place to go if you’re interested in the rock painting fad, which my family and I are. We went right before closing, (so sorry) but the guys at the counter were more than happy to help us. Only charged 4 bucks a bucket for the smaller sized rocks I’m requiring for a wedding project. Thank you for letting us rock around! This is what you’ve helped me make a friend’s upcoming wedding one to remember!

Cannot recommend Keystone Supply Company enough! After having a terrible experience elsewhere, we were exhausted and frustrated. The staff at keystone supply saved the day. It was a breath of fresh air to be greeted with such courtesy. Everyone we encountered from start to finish was very helpful, professional, and knowledgeable. Went above and beyond to be of assistance. Quick to deliver our order. Highly recommend.
