How can you tell if a wall needs plastering?

You can tell if the plaster is sound by knocking on it (not too hard!) in various places. If it is sound then it will feel like you are knocking on the brickwork itself but if it's loose you will hear the plaster knocking back against the bricks you may even see the plaster move in which case it may have to all come off & then re-plastered. 

If the walls are good and sound, then they can be prepped & re-skimmed although you will still run risks of new skim developing cracks on old plaster.

Skimming over it might be an option but you will always run the risk of re-skims cracking on old plaster. It can be false economy just having old walls re-skimmed as they might start developing cracks after a couple of years and you will need it to be renewed.

The first step should be to consult professional advice from a plasterer.

Plaster is a high-end wall finish. The installation of plaster walls requires special training and skills making it more of a labour intensive process than hanging or repairing drywall. 

Aside from these factors, a plaster wall can create a texture and feel to your home that no other wall can match. 

It is also considered the more sound resistant option, but the lack of insulation may mean higher energy bills over time.
