"Easily?" Not really. Prehung units are made to slip together at the
jamb and trimming there screws that up. It would be simple enough to
trim a 1/2" off each outer side of the frame except it's very difficult
to get the casing trim off w/ tearing it up. Unless I had a bunch of
them, I'd probably just opt to make the frame for it from scratch as
being quicker and simpler. But, I've a full shop--depends on what you
have to work with...
The short answer is no. You could add a second layer of 1/2
drywall around the opening in a picture frame effect. Make it
something like 6" oversized and edge with L metal. The prehung
will now fit, the trim will work, and you have a new accent.
Keep the whole world singing . . . .
Yes, it can be done. Easily no.
I had 4 closet complexes where I installed both regular (7) and bifold
(3) doors. Not a problem to make your own jambs if you have a table
or radial arm saw. Rip to width, cut to length, cut a rabit on the
uprights to accept the top jamb.
Of course mortising for the hinges (if any) and latch (if needed) adds
a bit of time and fool around. I have done all that in the past with
hammer/chisel and a few times with a router.
All those doors were done over a 10 year period rehabbing and old
With a prehung unit, remove the door and hinges. Take apart the
jambs. remove the stops. Rip the jamb right down the center (where
the stops will cover, then rip again to remove the inch (or
whatever). Your stop will cover the joint. You might want to
preinstall shims perfectly level, since it might be easiest to install
the frame in two parts. Not easy, no.
Yes, biscuits would work great if you have access to them. Also,
check with a custom jamb order. We used to get charged a measly 15
bucks a door for custom width jambs. Don't know if that would apply
to a 3 9/16" jamb or not.
thanks to all. i will probably go with just the new door in existing
jambs and trim, eventhough wife wanted new trim also....may be replace
that too...thanks again
