Having stripped wallpaper in my dining room there is black mould in the corner. It is over two walls and comes up to about metre. The water pipe for the house comes along the wall and up the other wall (upto boiler upstairs) but there is no sign of water, wood damage to skirting etc. I have had two cupboards up against the wall...for about 5-6 years but when I did a quick decorating fix 6 months ago I didn't see lots of damp/mould. One tradesman has said it is definitely not rising damp and it is just caused by condensation (being near the back door, covered by cupboards etc). He wants to sell me a basement damp machine but I don't want this and if it is condensation I'll use cleaner and solution in paint/paste. The other tradesman said it was rising damp (though he didn't seem to want to offer any other solution and didn't really speak - he just poked the wall and made a hole in it with a screwdriver!) and he quoted me £1000 to do damp proofing. I'd like to be able to know what the mould is caused by and how to identify it given that the experts in my area can't agree! Thanks
Are you a tradesperson and able to answer this question?
