Repairing rotting door jambs

[Rick Herrick]

I have two of these patio doors on the back of the house.  Each consists of one stationary side and one in-swinging door. Each has differing levels of rot at the bottom of each jamb.  The sides should be pretty routine.  The center stanchion/stile is another thing.  It looks like a piece that is 2.5" wide and 1.75" deep, with a piece of molding (2" by 3/4") over the top.  I picked up a few things from the big box stores.  Trying to anticipate what I might run into.  When I looked at it closer, it seemed the center section might simply be two regular jamb sides with the front trim to cover the space in between.  On the door side, the rot is also in the piece of the jamb that the door touches.  I guess I can get that out but the other side, the one with the stationary panel, won't be as easy.  Has anyone dealt with this set up before?  Any suggestions ?

Remove area from swing side, work on fixed side from swing side.

Forgot to mention, there will most likely be screws coming up from or threw the end of the sill.

Common issue with these types of big box pre-assembled doorways.
You could take it apart, splice in wood pieces. That is what we used to do. Its a PIA.
Depending on your need, how long you are going to live there, condition of the rest of the assembly, etc. you might want to take the easier route for now to push out full replacement.

They have good wood and concrete repair products. Also some good tutorials

The decay likely extends behind that finger-jointed stop material to the actual jamb which is problematic as this thing is hinged at the center and carrying all the weight of the door. Patching this might be a temporary affair.

Thanks Tom.  Looks like the only option.  Curious to what I find once I remove the trim piece on the front of the center column.
