Install prehungs in new construction

I just finished painting. Hardwood flooring is coming later this week. Do I install the doors now with putting a piece of 3/4 flooring under the jambs as a guide? All the doors go from 3/4″ hardwood to carpet. IF I do it like I described, will the jambs be sitting too far off the carpet on the other side of the door?
Do I wait until the hardwood floors are installed then notch out the bottom of the jambs on the hardwood floor side? I’d definitely refer the former for it would be a lot less work. Just curious how the pro’s do it.

I usually do what you asked. Use two pieces of scrap hardwood under the jambs. By the time the underlay goes under the carpet everything is at a nice height.
Last house I put all the hardwood in first because of a problem waiting for the painter, it worked out well but I saved cardboard to put down on the floor so I could walk around.

Around here there is no underlay put down for carpet, pad over subfloor. If you hold the jamb up 3/4 it would be too high for the carpet. You could take it up 3/8's for carpet and have plenty of clearance for the door swing. Remember the prehung jamb's legs come about an inch or so longer than the bottom of the door.
In this case if I wanted to get that work out of the way, I'd set the doors up on a shim and undercut the jambs when doing the hardwood. Some folks like the doors to just clear the carpet or wood-know this in advance and deal with it when setting the jambs.

That sounds like the best bet. When I set doors, they were always for laminate flooring so we used a piece of base trim as the shim. I can use a zero clearence saw to cut the jamb. How do I cut it vertically where the last piece of flooring ends? I hope you see where I';m coming from
For the vertical I use a sharp chisel, for the undercut-undercut saw or fein multimaster. The carpet turned under against the HW should cover. However, if using a transition pc, run that between the jambs to cover any overcut. I
f you do it after the flooring is down you can cut the jambs to fit the change, but usually time and conditions dictate the order you go.A great place for Information, Comraderie, and a sucker punch.
