I have a ceiling which sags 4 inches in the middle of a 4m x 4m room.

I have stripped the old plaster and stiffened it from above,
but is it worth the hassle of straightening it underneath?

Would I look at it for years to come if I dont thinking I should have?

Or would it be a waste of time, energy wood and screws?

What is the ceiling attached to? For example its common for ceilings
fixed to the underside of loft joists to sag under their own weight.
Normally is not even visible from the room below.

The only time its really work worrying about is if it is sagging because
it has become detached from what is supporting it.

4 inches is very noticeable.

Is this down to old sagging joists?

Has all the old plaster been removed? If so then I would tapered some 4
x 2 joists to suit.

It might be possible to place a 'new' lesser height joist along side the
old.

Otherwise mark the contour of the existing timbers onto the new. Then
cut along your line, screw up into place.

I would like to get it much more level. YMMV

The New Left are the people they warned you about.

John, its sagging from the weight of the plaster over a hundred plus years.

I've removed the plaster, stiffened the joists by screwing them up into 2 new 2x8 crosswise joists which go into the brick, but leaving the 4 inch sag.

I could screw plasterboard to them as is,
but would that show up and annoy me for years to come?
is it worth the time energy wood and screws to level them out is my questions?
advice from those of you who've done it or not

Fred and NP say to do the work and level it one way or another.

only you can decide. A least you can use scrap wood.

I would be a bit worried at why its sagging. I had an issue in this back
downstairs sitting room near the window some years ago, all it was was some
piles of books and magazines on the floor. I moved them and dispersed them
and the sag went away, but if a loft has had a weight in it for some years
its more than likely that the ceiling would be permanently deformed or come
away from its fixings. Brian

Not as much as you would think IME.

I was quite surprised when I did the loft conversion at my last place to
see the loft joists had sagged about 3" in the middle of the room.
However it was not at all obvious until you put a new straight 8" joist
over the top of the ceiling and could see the deviation:

(1" packer under the far end of the big joist - 3" of extra gap near the
centre)

Presumably the original sag annoyed you, since you did something about it?

is it worth the time energy wood and screws to level them out is my questions?
advice from those of you who've done it or not

Maybe you ought to have put a plank and couple of acro props under it
before strengthening? Too late to unscrew the old/new joists and do that?

Or leave it and call it 'character' ...
