Restoration & Refurbishment

Wallpaper or plaster

Anonymous user 15/03/2024 - 2.43 PM

I have a brick built house, built circa 1950s. Cavity wall insulation was done a while ago. The internal walls are also brick. The previous owners have wallpapered every room in the house. In one of the bedrooms the wallpaper has lifted slightly in one corner (inside and outside wall) and is discolored. There is some dark mold on the wall. I found similar in another bedroom and in the bathroom. The mold washed off easily and these walls have been recently plastered. I assumed the mold in bathroom was from condensation getting in behind the wallpaper. Could the mold be due to poorly applied wallpaper? Is by best option for redecorating to put up new wallpaper or get the wall skimmed?

Are you a tradesperson and able to answer this question?

There are many reasons for mould build up and so I am sure you will get a few different suggestions, mine is, you are right in assuming condensation in the bathroom and this is normally where hot air meets a cold surface. two things I would try in a bathroom, firstly an extractor fan to take the condensation out quicker or at least keep a window open, for the bedroom again its down to condensation when you sleep you exhale warm air which will condensate on cold surfaces, again its to do with not enough ventilation, most new houses have trickle vents in the windows which will stop it or again slightly leave a window open. Lastly for both rooms, the condensation hits the coldest parts of the ceiling and walls, normally the corners, for this you can check in the loft that insulation has been pushed all the way into the corners or add a bit more to insulate any weak areas from the coldness of the attic. I hope that makes sense and helps you find a cure. Best Regards Rod

Another thing to consider. A 1950s house should have air bricks along the bottom and top on the outside walls. You say you have filled the cavity with insulation which will block the air flow. You can buy a extractor fan which detects dampness and comes on automatically it may be worth looking into.
