How To Repair Rotted Door Jambs
To me, replacing a part of the door jamb that was rotting seemed like a simple job, so I decided to just try it myself.
Since my door jam is of the wider size, 6 9/16” , I spent a long time looking for an online store that sold just a piece and not the entire set, and I found exactly what I needed at a really great price, a 36” piece for $40!
I cut the door jamb to size using a jigsaw. I cut the bottom of the door jamb at an angle to match the slant of the door threshold that slopes down away from the house.
I used the door jamb piece that I had cut, as a template to mark the line where I need to cut on the existing door jamb.
I used an oscillating multitool to cut off the door jamb. I bought one for just $36 from amazon and it’s been working great.
I just put some black tape on the blade to mark where I should stop cutting into the door jamb, so I don’t go in too deep and cut into the framing wood that’s behind the door jamb.
When you try to take off the brick moulding, you may find that it has been attached using thick framing nails, which will be very hard to pry off.
I used the oscillating multitool with a metal cutting blade to cut off the nails.
I nailed the door jamb and the brick molding in place by using 16 guage finish nails.
