Quick question. Should pre-hung door be installed before or after the drywall? I've done both but there probably is a "best" way. Thanks.

After drywall.

Sheetrock is always done first!!
A whole lot easier to hang, finish prime and paint two coats on the drywall before the doors are installed so most can be done with a roller and cut out 50% of the cutting in.

Split Jambs (casing pre-attached) are always after. Solid jambs might be done either way.
