Cracks on plaster walls
But do bear in mind that the joints may not have been properly prepared when the boards were installed and may need to be raked out, scrim taped and filled. Hairline cracks along joints are very common and not normally a cause for concern.

If the problem area is fairly small, cut out the loose plaster and then screw the laths back to the joists and patch plaster to a flush finish.

Studwork partition walls between rooms can similarly be upgraded by packing them with mineral wool. In addition, to reduce sound via the roof void, fix a new layer of plasterboard over the ceiling, or board and insulate the loft floor above and line the firebreak wall with insulated plasterboard. Pack the studwork with mineral wool insulation and board over with two layers of acoustic plasterboard (such as British Gypsum (opens in new tab)’s SoundBloc) with staggered joints, sealing the joints with scrim and sealant. to the floor and ceiling – but not to the wall itself. This requires a minimum 50mm gap in between, with the framework secured at its edges – ie. One solution is to construct an independent wall of timber studwork and plasterboard next to the old walls, but not connected to it. There are a number of different materials and methods that can be applied to walls to deaden sound transmission.

Gaps in party walls can be filled with expanding foam to block air paths, and the wall then rendered or insulated for sound.Missing party walls in the roof need to be built up in new blockwork, or studwork lined with fire board.
