what do you think this is

[feva]

and whats causeing it? my sister in law is having a run in with the local council about it.




















the local council came out last year and painted the walls with watered down pva glue to in there words seal the walls.

and suprise suprise it came back, there was a load of old paint flaking off, so i scrape that off and painted the walls with oil based undercoat, the black paint is masonry paint, thats started to flake, has water running down it and mould growing, the pictures are of different corners, the room it self is a front pourch, was used as a bedroom till this started again, the council havwe suggested putting new plaster board sheets up to cover it all, that hasnt worked in a different house they tried it in.
they are trying to blaim a tumble dryer in the room as the cause but that is vented to the outside.

due to have another meet about it, just wanted some advice, some of the pictures i have been able to rotate.

cheers

It looks like mould, but deciding the cause of the mould is not easy.

It could be caused by condensation/poor ventillation or it could be caused by Rising Damp or by Penetrating Damp

It's definately mould, but without viewing the external area and area as a whole it will be difficult to determine what is causing it.
It certainly looks like it is bad airflow and condensation related

il have to have a look at the outside, defo mould, only happens in winter.

its always been a cold room, with it beeing a pourch, the front has a letter box, so slight air flow there, same with the tumble dryer vent.

if i can get round tomorrow il take some pictures of the out side see if you can see anything on them, to be honest ive never looked

You need airflow to the area!

[big-all]

as this seems to be a cold room it will attract mousture from other rooms

you need whatever is in the corner needs to stand away from the wall to aid ventilatation

you need to keep the kitchen door shut during cooking or adjacent bathroom during showering/bathing and ventilate the kitchen or bathroom to remove the moist warm air

no drying washing in this or ajoining rooms except in an externernal vented dryer

ventilate the room for a couple of hours a day

no using parafin or calour gas

as said above make shure theres no ingress from outside

I had the same thing on my walls in the front room and the brick behind plaster was wet through so the lot had to come off and the walls was treated with a damp cause then thay was replasted and jobs a good one because the wall is nice and dry, jim dale

Try Solarventi, my home is a converted butchers shop circa 1910 and suffered from a range of problems including mould (similar to photo,s) blown plaster on the walls, damp furniture and mould on the clothes in the wardrobes. I had one fitted and it's amazing. Runs on solar energy so once fitted you can forget it and it costs nothing to run. It even reduced my heating bills. Can supply a contact if you want.
