Installing pre-hung door with trim

Posted by DaveC on November 5, 2006, 9:16 am

Bought pre-hung door with frame (obviously) and trim already installed.

The only way I can see to install this door is to remove the trim from both
sides and, after installing the door and frame, reinstalling the trim.

Is this correct? If so, what reason is there for installing the trim onto the
frame?

I need to install the shims on all sides of the frame, so I can't see how to
install the shims with only one side of the trim removed...

Ideas?

Thanks,

Are you sure it is not a split jam that just pulls apart and you then
install the side with the door first, shim it, nail it, and then install
the other side and nail it? Mine are like that. Found a couple that
were not nailed on the non-door side.

Lo an' behold! It is a split-jamb.

But the question still rears its head: how do you install the shims to give
you a plumb-and-square install, when the casing is already nailed to the
(half) jamb? Access to the space between the rough opening studs and the door
frame is accessible from only one side (the non-casing side).

Ideas?

You can keep the jamb assembly square by nailing a diagonal brace to
the non casing side. Use the 3 4 5 rule to ensure square. Then install
shims using a Jamber level set or at minimum a 2' and 4' level set. HTH

You should have bought a "split jamb" door. Your thinking is correct, remove
casing on one side only. Leave the door in the jamb, to check your margin(
even distance between door and jamb). this operation requires 2 people.
