Hey Hoping you might be able to help - have had a few plasterers come around to quote me for works to my bedroom. All walls are lined with untold layers of paper and lining paper. The plaster certainly to the front wall (exterior wall) is blown. One plasterer has recommended, because the property is Victorian and may have lath plaster (?) that actually you could just plasterboard OVER the lined walls to avoid any uncovering of 'nasties'. Is this sensible advice / something that should be advised or something that should be avoided at all costs? We have chuff all cash so I think that was a reason for him making this suggestion. Your expertise would be HUGELY appreciated!
