I've been using Grand River Natural Stone for about five years now and I have recommended them to many people. Recently, I bought from them some great big boulders, around 400-500 pounds each, and put them in the front of my house and love the results. The people there are always on the ball and if there's something you're not sure of, they don't try to push you to buy it. They are very accommodating and they'll suggest something that you never even thought of, which is wonderful. I would consider their prices to be a 4 out of 5; most of the time, their prices are pretty good but some things were a little high. In the end, don't hesitate to do rock work with Grand River Natural Stone. You'll have a great time doing it and the after effects will be beautiful.
