I have some water damage to 2 lathe and plaster ceilings in my house caused by the fire brigade putting out a fire in the next door property. The ceilings are intact with a few bubbles here and there. The building contractor assigned said I have 2 choices either to rip the whole ceiling down or put plaster board over the existing lathe and plaster ceilings. The ceiling joists are 3x2 would this take the weight of the lathe and plaster and the plasterboard bearing in mind the previous water damage.
