I have a customer who wants an estimate for some yard work. I know what to do with everything but the lawn. The front yard is 40ftx30ft and the back is 75ftx50 ft (roughly). About half of the lawn will need releveling and patching. The lawn is a few inches lower in many areas, so I figure I will need to bring in a lot of topsoil . He would like an estimate for seed and for sod. How many square feet is a pallet of sod? Is it possible to only sod part of the lawn, or will it not look good with the original lawn? He thinks the soil may wash away before the seed grows. I think I may get a quote to sub out the seeding to a hyrdo seeding company. What input or suggestions do you guys have? I have never done a lawn redo of this size, just smaller areas.
