As in my previous post, the is a right thing to do and a right time to do it for every problem.
As to what your guy told you is Kyllingea Sedge assuming he is right. You can confirm if you look at it. Grass has flat leaves. Nut sedge has a triangle cross section. In any case there are chemicals that will kill only the sedge and not your regular grass-slegehammer is the trade name.
Sedge is hard to kill because it produces bulbs along the root system. So if you pull it out it comes back from the bulbs you will leave behind. Not only that it also produces seed.
READ-instructions will tell you now is the wrong time to be applying weed killers-they work best on rapidly growing weeds-spring time. Your OP said you are considering replacing your sod. Realize if you have sedge when they remove the old sod they will surely leaqve some sedge bulbs behind and you will still have the same problem.
If, yo feel like you must to something and do it now, spot treat each weed with Round up-glucophospahte is the generic chemical name. You can apply it with a paint brush to avoid killing your grass. Muttering-TAKE THAT YOU SUCKER helps make it seem like less work. Particularly now because all is shutting down for,"winter," it will take about two or three weeks to work. The chemical is absorbed through the leaves. Do not remove the leaves even once they start to wilt-you want to be sure to kill the bulbs.
