We had their service for about two years. The person in the office said it would take 1 ½ years to see a improvement in our lawn. After a year and half my lawn was still full of weeds. I contacted the owner and he came over to see my lawn and said that there were too many weeds and he would be back the following week to fix it. He had to use a special weed killer that would kill the weeds but would enable him to aerate our lawn in a couple weeks. He did kill the weeds but never came back to aerate. I called and never got a response. So it is now spring again my lawn looks like crap. I would not recommend them. Looking for someone who knows how to grow grass.
