    Default Advice on sagging ceiling + loft insulation

    Hi guys,
    I'm getting loft insulation fitted in the next few weeks (thanks to government grant )

    When I bought my house, the ceiling in the main bedroom sags down in the middle, and you can see the outline of plasterboards...
    The loft space above it has NO loft insulation (reason for us having it done) but I'm worried that the ceiling will fall through if an engineer dances on it, or if overtime the extra weight of the insulation causes it to give way.


    Does anyone have any advise or rough prices on how to make the ceiling joists stronger to take the extra weight? We're not bothered about the sag, as it's not noticeable unless you look closely.

    I know a new ceiling would be best in the long term, but I'm thinking of any short terms problems so we can get the insulation done, then sort out properly in summer when we're not shivering in bed.


    I'll try and get some photos of the ceiling and view from in the loft so that it makes more sense.

    can you re-fix the plasterboard from below, screwing into the joist above? And then make-good the screwheads in the room....

    The fitters won't jump on the ceiling (hopefully!) or they'll come through any plasterboard no matter how it's fixed! and the lagging weighs next to nothing... the lagging lays on the top of the ceiling board (between the joists) so no amount of 'strengthening the joist' will affect the lagging. hth

    It's the joists themselves, that are sagging down. The plater on the ceiling has cracked into the outline of the platerboards that are attached to the joists.

    The plasterboard is not sagging, its the joists that they are attached to.

    The ceiling dips towards the middle:


    Causing the platerboard ceiling to crack around the edges of the boards (stands out a lot in picture because of the flash - doesn't look that bad in person)


    The view from inside the loft - part of the floor has chipboard on it, which you can see sagging towards the middle of the room below.


    Amazing how much insulation I have.... especially as it's an end terrace too
    (no insulation in either ceiling joists or below the roof tiles.)

    How old is the house? Normally older properties with traditional timber roofs have decent size timbers that wont sag under the weight of the ceiling. (insulation certainly isnt heavy enough either) possibly there has been a roof leak in the past and the joists have warped? (might be why there isn't insulation above that room!) or maybe the roofspace had too much weight stored up there? Your new insulation is going to cover the joists (it should be 250-300mm thick) to work properly so maybe no more storing stuff!

    What size are your joists?

    I had that. turned out to be cracked joists. (as I was told rather animatedly by a wrokman who damn near landed on the floor below after trying to walk on them. Good job he was employed to replace the ceiling though.


    nearly asked for a discount due to him having to spend less time on the dismantling.

    looks to be quite a bad sag so counter battening wouldnt work, cracked joists sounds a bit extreme. personally i would go for a slightly lowered ceiling with 3" by 2" timber plaster boarded and skimmed some vertical battens in the loft to tie the ceiling joists into the roof joists. not as expensive as you might think as these are only cheap basic building materials, hope this helps

    If you dont use your loft for storage, you can buy metal straps, get accro props under the ceiling to take the weight, then attach the straps from the trusses to the floor joists to hold the ceiling up
