Prehung door question

[sthompson82]

Working on finishing a room in my basement and all the work is done except hanging doors, trim work, and painting. I purchased a 36" prehung door to separate the room from my shop and thats where the question comes in. The framing on that wall is 2x6 framing, and the prehung is designed for 2x4 (ie, it wont fit together because of the casing.

Can you purchase a prehung door for 2x6 framing? Should I just take the casing off and mount it? Other options?

I looked online and couldnt find any info for my situation. In my case, that usually means that the answer is incredibly simple and I am being an idiot again.

When I was working in the millwork dept. of Home Depot, we sold "Jamb Extenders" for entry doors. Thee set of extenders allowed you to install a door with a 4 1/2" frame in a house using 2 x 6 framing (now popular due to the new insullation code here in the north east. I assume that you could adapt a jamb extender to allow you do do the same with an indoor door, although it can be special ordered with a frame for 2 x 6 construction.

If you hate Home Depot (like most sane people do, a good lumber yard can help you out without the BS you have to go thru at HD.

I dealt with this once by simply butting some 1x stock against the jamb to cover the remiander of the exposed stud. It actually turned out looking good...just make sure to pick some nice grained stock of the same or similar species wood, and finish it the same as the jamb.

Also, you would need to make sure the mount the jamb flush with the outswing side of the wall...if that makes sense....?

My shop is bare stud walls, so I wouldn't give it a second thought to just install as is. That's assuming the door swings out from the shop, so the finished part of the basement isn't affected.

As others are mentioning, you can make up your own jamb extension if you do finish the walls in the shop. A thin trim piece could cover the seam.

It kind of depends on how nice it has to look. When I did my basement, I bought un-hung doors because all the framing the builder did is 2x6 which includes the walls the doors go in. I bought cheap knotty pine shelving boards wide enough to make the door frame (and primed them with Kilz). For doors in the finished area of the basement, the frame for the door is the whole width of the wall including the wall board. For a couple doors from my shop into an unfinished storage area and the unfinished utility room, I got cheap and did not make them the full depth (it looks right in my shop, just not in the unfinished spaces).

The simpliest way to deal with this given that you have a door frame is to use it and fill-in with pre-made jamb extenders or 1x pieces you rip to size. It will probably look better if you do not try to make the add-on pieces perfectly flush with the door frame. It is hard to make it perfectly flush, in other words. You could install the door and then install the extenders to make a 1/8 or so reveal between the two that makes it look like they were not supposed to line up flush with each other. Both can be nailed to the 2x6s.

Jamb extension

When we bought the house we're in now, we replaced all four exterior doors. HD delivered one of the for a 2x4 wall even though the others were for a 2x6 walls. They wanted a $150 restocking fee. So ...

I used 1x3 clear pine and ripped it to the proper width. I attached it with Gorilla Glue and pocket screws. Once the seam was sanded perfectly level, you couldn't see it.

I think twistsol's suggestion is the best. That way the extension is part of the jamb.

Thanks for all the advice. Since my shop is "unfinished space", i decided just to hang it as is. I will probably end up adding some 1x pine to make it look a little more finished, but at this point I just want to get the project done.

All the base trim and window casing is installed. Now I just have to caulk some small gaps, paint the trim, and then the walls. Then carpet guy comes next week. Looking forward to having a little extra space

Then carpet guy comes next week.

Ahhh, that's the sweetest part. It's like the project goes from "not done" to "done" in one day.

Enjoy!
