But if you are expecting aeration, double tall fescue reseeding, sifted topsoil and all of that other nonsense that Orangedogsrule highlighted, then that conversation should have been had BEFORE construction even started. If the contractor is going to have to make special accommodations to complete this project (buying grass seed, top soil, sod, whatever), then that would have to figure in to his price of doing the job because it is added time, labor and materials.
Spent my whole career in design construction. Some in project management. Some in real world Commercial & Residential. Done the research. Had some professional inter-actions with UT's ornamental landscape & turf grass profs, and several seed and lawn & garden and co-op pros. I aint blowing smoke, I've seen the results.
One thing we always expected was that if one sub came in and screwed up something not a part of his job, he'd make it like it was before he started.
Example, plumber does a piping install but busts up a lot of drywall and leaves. He either makes it good himself, or the price to "scratch & patch & paint to match" comes out of his final payment, which was where we allowed his profit. Surprising how neat and tidy one works when he knows his profit is tied up in leaving the rest of a job site like he found it, no trash, and broom clean.
That said. Read my post. I know it's an old saw now on VN to gig someone on reading comprehension, but...well..the shoe fits you.
I did not hold the contractors of my jobs at my home responsible for the renovations needed to my yard because I expect more of my lawn turf than the average homeowner. More even than most who do the regular seasonal tricks.
I want a truly "Barefoot Lawn". So what I said to start out with was what it "needs" to get an even and all over healthy growth, and listed it. I did not say the contractor should follow my list. However I did state that based on my experience that it damn sure needed a LOT more than a 1/2 hours worth of raking. I've been there done that, and have a tried and true method of getting a beautiful even, healthy stand of turf grass.
Now we read the OP got sod put down. Good for him. That can work exceedingly well, ...or not, as far as having a uniform lawn.
