I worked on one doorway/pass-thru myself. Using my not-so-great table saw, I ripped three 8-foot 1x6 stock down to the maximum jamb width (it varied almost 3/8 inch around the permimeter of the jamb, due to the metal edge and mud on top of the drywall) and shimmed all. When I nailed up the casing, of course parts of the casing were up to 1/4 inch off of the wall surface, while other parts of the casing were flush. So the casing had to be shimmed, and heavily caulked to make it look right. Took me about 8 hours to get all done on just 1 (out of 4) doorways.

Ripping an 8 foot 1x6 is not easy with a cheap table saw, and this took a few tries (1 ruined 1x6) to get right. Tough to get a precise edge on such a long cut.

Unless you have a good table saw, I think it will be better to cut off the drywall, back to the stud where the wall is a standard width, and buy a pre-cut (4 9/16th inch ?), pre-primed jamb from Lowes for about $12, shim/nail this in place, and apply the casing.

I cried uncle on the remaining 3 doorways and had a carpenter do the work for about $50 labor per doorway. He had a better table and miter saw (and skill!), and could back-cut the casing to be flush despite the uneven surfaces. ]]> http://www.dslreports.com/forum/remark,19639271 Mon, 17 Dec 2007 16:14:48 EDT Re: Adding trim to untrimmed drywall doorways http://www.dslreports.com/forum/remark,19581592 Greg_Z : Then that is considered a Pass Through. Adding the trim may involve removing the Gypsum Board from the inside edge, otherwise it will not appear correct. I can see doing what you are thinking about as protection, but keep in mind, that you are narrowing the opening by at least an inch, and can be noticeable, especially if you have to move items through that doorway (ie wheelchair).]]> http://www.dslreports.com/forum/remark,19581592 Fri, 07 Dec 2007 14:29:42 EDT Re: Adding trim to untrimmed drywall doorways http://www.dslreports.com/forum/remark,19580115 elless :

Are these doorways, or pass throughs into hallways, and other rooms? If they are pass-throughs or archways, you will have to do something other then just put trim up on the opposite sides to make it look good, otherwise it will look odd and out of place.
I agree that just "trim up on the opposite sides" might look odd; I plan on installing a jamb on the inside of the opening with a frame/casing/trim (whatever you call it) around the perimeters of the opening. Imagine a normal interior doorframe with the door and doorstop removed.]]> http://www.dslreports.com/forum/remark,19580115 Fri, 07 Dec 2007 10:23:45 EDT Re: Adding trim to untrimmed drywall doorways http://www.dslreports.com/forum/remark,19579668 Greg_Z : Are these doorways, or pass throughs into hallways, and other rooms?

All the corners should have studs and you are nailing to them not the drywall.

Are you just adding trim or adding a door/doorway frame ?

You do not need to remove the drywall at all, but you can. In most of the new construction we do, we are going over drywall. But I think that is mostly because we are going over metal studs.

If you go right over the drywall, it might be straight enough for you to get away with not using any shims.

You will probably want to use 3/4" for the jamb, but you could get away with 1/2". Use some Liquid Nails on both the jamb, and both sides of the shims if you use them, and on the casing. And be sure to glue your joints. The standard is to leave a 1/4" reveal on the jamb, or match whatever the rest of your house is, if its different.

Good Luck.

So I'll be shimming on top of the drywall too?
Yes that is what you would do. Like I said the only downside is that the doorway would be smaller, I don't see how strength would be affected at all.

Thanks for reading my mind, that is exactly right - a jamb on the inside of the opening with a frame/casing around the perimeter.

I know just enough to know I have to shim the jambs plumb if I remove the drywall, but that seemed a whole lot more stable than installing the jambs on top of the drywall. Especially after nailing the frame/casing to the jambs.

As the earlier poster noted, the drywall has corner beads. And if the studs arent straight, then the existing drywall and corner beads arent either. So I'll be shimming on top of the drywall too?

I was hoping to find someone who has gone the easier route, and left the drywall in place, with some success/tricks if possible?]]> http://www.dslreports.com/forum/remark,19576949 Thu, 06 Dec 2007 19:04:35 EDT Re: Adding trim to untrimmed drywall doorways http://www.dslreports.com/forum/remark,19576925 vapochilled : Our house was the same when we moved in.

My first thought was that you were going to install a jamb on the inside of the opening and put up casing around the perimeter. However after reading your post a couple times, I'm not quite sure that's what you mean. Is that what you were planning? I kind of got the impression maybe you just want to put up the casing, and leave the drywall on the inside of the opening.

Assuming you want to put up jamb and casing, I really only see one reason to remove the drywall and that would be that the finished opening is going to end up being at least 1" smaller, than if you had removed the drywall. If you do remove the drywall, the jamb would not sit directly on the stud anyway. It should be spaced out on shims to make it straight (studs are never straight).

But i don't see any reason you can't do what you originally suggested, except the drywall corner might have a bit of a rounded edge and look off.

I would like to add trim pieces to frame the doorway, to match the window trim in the room.

My question is: Can I just place the trim pieces right on top of the drywall that wraps the door opening, and nail them to the underlying framing - driving the nails right through the drywall? Or should I bite the bullet and use a reciprocating saw to remove the drywall around the doorway edge, exposing the framing, before nailing up the trim?

I have this feeling that nailing finishing nails through the new trim, then through the plasterboard will leave the final assembly somewhat loosely attached to the wall.

If it matters, I only want to install paintable trim pieces, not some fine finished/stained trim.

Has anyone ever done this? Your thoughts?]]> http://www.dslreports.com/forum/remark,19575467 Thu, 06 Dec 2007 14:59:12 EDT
