Greetings everyone, I posted a while back about a project I was looking to do. I ended up finding a local company to do the work, and overall they've done a nice job (from what I can tell, but that doesn't say much). I have a few concerns, and I'd appreciate it if I could get some independent opinions. They put in about 12 tons of boulders for a retaining wall. Looks great. They're using very large (I'd say 5x5 or larger) flagstone pieces for the patio and using polymetric sand in between the "joints." So, my questions are: 1) The patio sits at least 6" or more above the grass line. This wasn't what I was expecting at all, but he says it was necessary. I disagree with the idea of that from a customer service standpoint, but I can live with it. Is there any issue with having the patio level that far above the grass line? I'll try to get a picture if it helps, but I thought the patio line should be roughly level, or maybe a few inches above, the grass line. 2) The most disconcerting for me. There's a long crack in one of the largest pieces of flagstone. It snakes around the stone and is probably 6' long. I can't tell how deep the crack runs. Should I refuse this piece? Is it normal to have such cracks? I hate the idea of paying for a new patio, and though we're using stone that's who knows how old, I'd like to have relatively flawless pieces. Opinions greatly appreciated. As a consumer, I've thus far been pretty frustrated by the experience.
