Topic: urgent. help needed. ceiling problem.

we have had bad condensation in our bathroom. made worse by the council knobs removing the fan.

we've installed a new fan and I'm making progress taking of the spot of flaky artex.

I have discovered 2 holes.
1 was from a previous shower installation. not very big, but was filled with tissue then filler on top.
the other is a mystery, but they used cardboard and poorly patched it. it's in the corner close to the pipe hole, a triangle about 2-3 inches each side.
I'm able to push the card board through to the attic.

what is the best way to fix it?

[Lisa]

here is said hole.
may have to call someone out to fix it

Many ways. Some complicated. The most obvious thing is to grab the original bodgers by the nuts and crush.

You have to make any "backing" secure before filling the face side. If you can get to the other side you could securely fix a sheet of plasterboard or plywood bigger than the hole with plasterboard screws. If you can't get to the other side, you should feed in a patch of plasterboard or plywood with a temporary screw as a handle. This will allow you to pull on the patch as you drive in plasterboard screws to hold it in place. A lot depends on size and any voids.

That triangular hole is where a pipe fed into the attic. It was probably silicone sealed, then just ripped out when they did their "work". You'll have to remove the sealant on the tiles before the repair, then replace after the area is fixed and fully dry.

can't get to it from attic side.
it's right down the bottom of the eaves.

a bloke in the street is a plasterer and he said he'd skim it for me.

they were doing work in the residential complex by me, so I popped in to see if they have and plaster board cut off, but they didn't.

Check the bins after they leave 

[Lisa]

they've already cleared the crap away.

  No bits of plywood about? You need a triangle about an inch longer on each side. It can be fed into the hole, and glued/screwed in place. No More Nails (or similar) is great for the job. Poundland sells it.

I have no nails. been told not to use wood

Any triangular space memorabilia? 

[Lisa]

yes, I'm sure there is

wire mesh above the hole held in by filler above the remaining board.

Several thin layers of filler is then the key (scratch each layer to provide a key for the next).

Lasted 20 years for me so far
