Spray Lawn Hydroseeding

I would not use this company again, or would I recommend them to anyone. I had 23,000 sq. ft. hydroseeded, of that portions never grew, followed all recommendations per their web site. I called Greg the owner four times and my wife once, never once did he return any messages we left with him. He claims to have a one year guarantee, alot of good that does. My next step is to file a formal complaint with BBB. Craig in Maple Valley
