Recent Review: I had them build me a large stone waterfall. It runs off of a pump. It stands 8 feet tall by 10 feet wide. At the bottom of the fall is a pond 6x8 feet. It is made of stone as well it stands about 2 feet off of the ground. It took about two weeks to build. The cost may sound high, but if you could see the labor and materials went into making this, you would know why. I would defiantly consult with them again.
