can anyone help?
i have had 3 reputable companies to assess and quote for 2 remedial damp works within my property - they all have a different take on the problem and vary in their solutions ( and price 600-1000£ ex vat.) not surprisingly i am very sceptic and reluctant to do anything!
i have lived in the 2 bedded terraced victorian house for about 6 years.
last winter a large damp patch appeared in the front room above the radiator- there is a damp proof course in place.
i have been told that a) the damp course has been compromised and the plaster needs to be ripped off and another damp course injection carried out. equally i have been told that the damp proof course in in tact and the most likely cause is that the damp has been trapped above the chemical damp course membrane and is simply "coming out" ,recommending that the plaster is hacked off and then replastered.
another damp patch (large) appeared over the kitchen wall unit cupboards- there is an extrnal w.c , the roof joins below the damp level -
i have been advised we dont know why this is happening to it must be penetrating but we dont know where!
does anyone have any sugestions
