Topic tags/keywords: prehung door back room addition

I need some help with a project I am trying to do this weekend.

We found a prehung door at our local Habitat for Humanity store. We needed to replace our old back door that leaks air like a sieve and keeps opening on it’s own.

I thought it was a prehung door. I was wrong. It is not. That means I am going to have to make the opening larger.

This door is in an addition to our 1930’s house. Someone converted the cement back porch into a back room. The door was hung onto a 2X4 that is part of the wall. I am going to have to move this 2X4 over to accomodate the prehung door. I am also going to have to move the single 2X4 header upward as well.

My biggest concern is properly reattaching the 2X4’s to the other 2X4’s and the cement floor after I move them.

I did manage to get the door hung. It is a nice door, it has the blinds between 2 panes of glass.

We discovered why Habitat for Humanity had it. It was odviously a factory reject as it apparently did not pass inspection. It was not square and the hole for the deadbolt was slightly off. There were a few scratches on the paint as well.

This was my first time to hang a door and I am happy that it turned out ok, so far. I still have to put the sheetrock back and do some trim boards around the outside (and inside-that will come later as we will be texturing and repainting this room later) I also need to apply some silicone calk. I already used the low expanding foam to seal up most of the gaps.

The door closes with a single push. I consider this a small victory and it is a lot better than the door it replaced.

To answer my own question…

I went to Lowes to get some trim boards for the outside of the door. I stopped to look at one of their books on framing, just to see how a door should be framed. As I flipped through the pages I saw some framing done with joist hangers.

That’s it I said, and went to the aisle where they had such things and got some L brackets to use. So in the end I used L brackets to secure the King stud and header to each other and the rest of the framing.
