when i bought my house the external wall was completly sodden. It had previously been cavity filled a few years before. i have heard from neighbours that since this was done there had been problems with damp. However due to the extent of the damp the whole outside wall was hacked off allowed to dry out and completly re rending, also the inside of the wall was hacked off and re plastered. now 1 year on i have patches of damp showing on the upsatirs wall. Cant afford to do anything else, what should i do. Sinlge women on her own with no one to ask and more ideas. please help
