Damp Proofing Question

Condensation or something worse?

For the past few months I have noticed increasing black mould in my house especially in the two rooms at the side. The downstairs loo at the front has always been damp with the wallpaper coming away from the wall, about 6-8" from the skirting. I have also noticed this afternoon when wiping the mould away from the wall in the kitchen that this wallpaper is also coming away from the wall. In the other rooms upstairs there is general black spotting around windows frames. There is no obvious sign of damp on the outside walls although the mortar is loose where the wall meets the paving. It is a detached house with central heating (although not in the downstairs loo or kitchen) and double glazing. Thanks for you help.

Hi there
It does sound like condensation but you would need a survey to give an accurate diagnosis the problems are in areas where you would expect to find mould due to condensation but this is only guessing I would need to look at the areas and assess

Black mold is a condensation problem, more than an external damp problem. Do you have working extractor fans in the bathroom? Have you had the loft insolated? Basically the atmosphere can only hold so much water and when the air hit's any cold walls it condenses causing mold. Options are.. air vents to help circulate air, sort extractor fans out, keep doors open to help air move around the property. Etc
