Do I need a re-plaster? Or it this repairable?

[jifferz]

I stripped the wallpaper in our 1930s semi front room. This has revealed and also caused some damage to the plaster, a good chunk has come off around the fireplace surround (which I have just removed), there is a fully blown area; and a few areas that either show signs of damp or have been damaged by previous building work. I think the walls are all single skin. I plant to board up the fireplace after the gas fire and hearth is removed.

What would you suggest for getting this rectified? I started the job, thinking I would DIY rectification of the chimney breast, but given the damage elsewhere in the room I'm thinking about whether I'd be better adding/moving some electrics and getting someone in to do it.

What would you suggest? I'm not sure what scale of the job really is i.e. is it repairable? Essentially if I was to do it myself - what would it involve? Repairable - or would I be looking at having to chissel off all the plaster to re-do it from brick, or plastboarding it over? Or would I just need the exposed brick areas re-plastered and the rest skimmed?

Thanks!

Cavity wall on your house?
Yeah plaster skim with either limelite or gypsum.
If plaster it's still stuck on you have a choice. Patch up or get it off. The advice is don't go digging sometimes as it's a can of worms. Never used a steamer to remove wallpaper either

Non cavity walls, all brick as far as I know.

So in the areas where big bits have flaked off and the bare brick is exposed, I could get anything loose knocked off, but then fill in gaps. When prime say “skim” does that mean thin new plaster over existing plaster? I.e. if it’s bare brick it’s not a “skim”?

Thanks
