Unfortunately I cannot leave 0 stars.
My neighbor and I both had our yards put in by this company and we now have a pond between our yards when it rains. It was sketchy from the get go. He would tell us he was coming out to put it in and not show up unless I called to ask where he was. Then trying to get the pond fixed he would always say, oh next week I can get out there. Then sometimes when I'd call he would not remember the situation.
I figure if he cannot put a lawn in and get the drainage right, any more advanced project is probably going to get done wrong. Seriously, if you want to waste your money and time being lied to and having poor work done, use Earthscape, otherwise hire someone competent.
