Property I am buying (sold stc) has damp - I knew about one patch as is visible to naked eye but further investigation by damp investigator has found more in other rooms. Apparently nothing sinister or overly urgent and to be expected in property this age (built 1910). Have been quoted £1500 to knock off plaster, put in damp membrane and re-plaster ready for decoration. How do I go about negotiating this with vendor? I sent an enquiry to solicitor but she said negotiate through estate agent. No idea where to start, what is reasonable/the 'done' thing! Full amount of part? Knocked off sale price or paid another way? Expect work to be done before I move in/exchange (apparently a three day job) or once I've moved in? Any advice appreciated!
