I'm going to putting in a new lawn for my grandpa this year for him since his lawn was attacked by grubs a couple of years ago and now he just done messing with it and asked me if I would put in a new lawn for him. How much do you charge to install sod sqft? And how much do you charge to take out the old lawn in sqft? I will be rent a cat skid loader to take out the old yard and level it off with some new topsoil. Then I will be installing the sod and maybe some irrigation for him. How much on the average for a 1/4 acre cost to put in an irrigation system? I have found a supplier on here that I can order parts from when I need them.
