Worst reno project since we bought this house - and there have been many projects! Buyer beware! After tilling, you will pay for someone to bring in manure (have since been advised this is very dangerous because...keep reading...). It appears, based on every other professional we've had come out since this disaster, the manure will bring NUT GRASS into your lawn. We had a decent lawn and after spending nearly $4000 with Roto Tiller Guy we now have an entire front lawn of NUT GRASS which is almost impossible to kill. When Mike did finally come out and look at the lawn his crew installed and all the nut grass permeating the grass that hadn't already died in a week's time, his response was that he was "not responsible for that and that now would be a good time for us to start getting rid of all that." Pacific Sod who Mike calls for you to purchase the grass will replace your dead grass but they can't do anything about the manure that will permeate your lawn. After this big expense we are left MUCH worse than when we started. A huge disappointment that we still have not been able to correct despite investing much time and money and consultations with true experts. You won't save money with RotoTIllerGuy - you will waste money and you will have begin again and invest much more money the 2nd time and you will probably never be able to rid yourself of the nut grass that will have been planted in your yard by RotoTillerGuy. In addition, much of the lawn is dying. Have been advised this is due to the fact that the sod was laid incorrectly, one on top of the other instead of like bricks as is correct. It was also laid with space in between which lets in air and dries out the grass. I could have done this so much better myself and really wish I had! Learn from our huge mistake! As many others have mentioned, since RotoTiller Guy is not listed with BBB there is no way to report this company...so hopefully this review will save you all the trouble we have purchased.
