Hi, this is my first post.
I've started having a problem with my front door frame. It seems to be slowly shifting into a parallelagram instead of a rectangle. The right side is shifted up a fraction of an inch or the left side is shifting down. The left side has a crack running away from the top left side.
There's the right side
the left side with the crack.
The bottom's the same way only reversed.
This little shift makes the door VERy hard to close as you can imagine.
Any ideas? I don't know if this is a serious problem or one that can be fixed with some work around or what? I was thinking of just going to the bottom of the door and shaving off some on one side to make it easier to open, but i don't know if that's just ignoring the real problem.
Thank you guys!
There is a crack in the sheetrock in the 2nd picture (lower Pic) that is taking place on the left side of your door casing. You also mention that your door frame (Casing) is separating at the upper miters.
My suggestion: You have a framing issue. What you are seeing are the results of the structural area above your door sagging.
What is above that door (weight wise) that is causing the area to to sag?
Is there a structural header installed?
If so, is it a proper dimensioned header for the load above?
Are there other structural issues that could also be causing this - even with a proper dimensioned header installed?
The way to find out would be to remove the door casing and the sheetrock above it to determine what the issue is.
Any-how - that is what I am getting by looking at the small pictures and your description (?)...
