The house is a very old (1900s) cottage which is up for sale. I bought the house about 12 years ago and hubby has lived here for about 4. I've noticed that one wall is very wet and water must be getting in from outside. I've spent years and £1000s trying to get the house damp free with little result! As it's up for sale hubby has been lathering on damp proof paint which has obviously helped but it's just masking the issue!! I think doing this is hiding the issue from buyers which I feel is un ethical... He thinks this is absolutely normal and moral ... Who's right,!?!?
