Rotten Door Jamb
My 15-yr old front door jamb is rooting at the base on each side. See photos where I'm using some Tyvek tape to try to slow down mother nature. The door is fine, but to change the jamb out I assume it would be best to go at it from the outside but there is all of this foam trim around the door which I assume I'll wreck trying to get it away from the jamb.
Also, see in the photos where the door threshold is embedded in the concrete of the step. I would have thought that the threshold should be above the concrete?
Any suggestions as to how to do this:
1. without losing all the foam pieces or should I just resign myself to wrecking it and having replacements on hand?
2. Should I try to chip away the concrete so the new threshold is not as level with it?
I hope photos went with this post; my first time.
Thanks in advance.

Smith's products are my favorite.

There seems to be some science behind them. This is very interesting reading:

Do you get a lot of jobs needing that kind of product, or do you just have a beautiful hundred-year-old wood house? :thumbup:

I really don't want to restore the jamb as I think the original install was bad (concrete same level as threshold will keep sending water the wrong way) and the problem won't be solved just put off: I want a longer-term solution. My questions remain:
1. chip concrete below the level of the sill?
2. Can I remove jamb from inside without disturbing the foam moldings or should I just start from the outside going inside with removing stuff?

It is hard to tell how this is trimmed out with the pictures. But lets look at it this way. Remove the trim from the outside carefully. This should be possible. so you save the trim your worried about ruining. Then you can see the door frame and can cut the nails / screws holding the door frame to the structure. Remove the door and frame. Replace with a new prehung. As for the concrete you will not be able to just chip away the step it will need to be removed and remade. Chipping concrete is not like sawing wood it won't be smooth. You may want to have a contractor come out and give you some ideas first hand when he can see the issues.

The exterior trim is that polyurethane-type moldings. I assume it is glued to the door framing (joints have been caulked and painted so you can't tell which piece belongs to what).
I realize "chip" was not really the right word; I assume I'd have to jack hammer it away low enough and then reform it and repour new but since I'd only really need to lose about 2" of height I was hoping for something like a concrete top-n-bond for that. Would that work or will I need to take it down more and use concrete mix?

I appreciate the input,

Top and bond should work for a few years. As for the trim it might be all one piece. Nonetheless it will be a tuff thing to remove without damage. To do this properly you would want to plan on replacing everything. If it ends up you can save some things it will be a plus but be prepared to replace it all if need be.
