I have lived that nightmare...so I thought... a few times. They strip the topsoil and stockpile it. When they are done the "DEAD" topsoil is spread back. The topsoil can come back to life but laying sod over it is hit or miss especially if there is limestone involved. The next issue is in stages. Your lawn comes to life but down the road the dandelions are thick and infect you lawn.
I wanted a green weed free lawn.....isn't that the goal?
Now that I am into growing stuff for food and pretty stuff things have changed. Those weeds were there for a purpose. The deep roots pull up nutes and feed the others. The more weeds the better stuff grows as it all works together. Trying to fight it makes for a nightmare of ferts, pesticides and keeping up with the Jones'. It all mows the same. I no longer have to spray, water or fertilize.
The violets, broadleaves, dandelions, clover and creeping charlie and others are just mother nature trying to correct itself. AND it will!
Or you can spray and kill. At that point your best best is 1 inch plus of leaf compost spread over the yard before sod. You will still be chasing deep rooted weeds.
