Gap between door casing and architrave - how to fill?

[R D S]

I've overboarded a wall and as such i've a half inch gap between the
architrave and the door casing, internally.

Gut feeling... Foam, trimmed when gone off then thumbed in a mm or two
then sandable filler?

Any opinions?

[The Natural Philosopher]

should work. Or you can use about anything to to the mass fill -
polyfilla is good

If there is likely to be movement use decorators caulk for the top finish

Do you mean a gap between the back of the architrave and the wall, or
between the architrave and the door frame because the plasterboard now
stands proud of the door lining?

If the latter:

You've made me think...
The door casing is only held in with foam and has no architrave on the
other side under the stairs, i'll pull it out and refit it an inch forward.

Now why is that, i've gone to pains to make them flush!
(To make any potential filling easier, except as I think about it it
wouldn't really have made any difference..

Like most of these building "rules", because it was decided at some
point that it looks better... however there is usually a practical
element as well - if you fix things flush, then you can normally
guarantee they won't remain so with seasonal wood movement - so better
to make a feature of the reveal rather than have a line that splits the
paint each season.

Apparently having some sort of gap or inwards step in the plasterboard
around door linings is the 'modern' way -

But anyone who has resorted to some sort of DIY plastering around
door linings is probably glad to use some sort of architrave trim
to hide the result :-)

Interesting. And my hinges won't go back the same way without some
chipping away.

Now there's ugly for you :-)

(not to mention built in dust traps, with lots of places for shrinkage
and settlement cracks to become visible)

Indeed... and that is one of the reasons these things are traditionally
done, so you can fit square and plumb lining to what might not be a
perfectly matching hole in the wall, and then "tune"[1] it to the door
to get even looking gaps all round. Ultimately you need a way of hiding
the mechanisms used to make this all work from view.

[1] i.e. when you fix the lining, you want it square and level, but the
opening might not be, so you need packers to bring it square and plumb -
leaving visible packers and gaps behind the lining. Then once the door
is hung, you want the gap to be even all round, so you can hammer wedges
between the opening and the lining to move the frame slightly (which
will be fixed in the centre of the board deliberately so the edges can
move).

Hence on reason why you have architraves to hide any gaps, packers, and
wedges.
