Advice please on what is happening here **see pics**

simo28

Hi all I'm desperate for some advice here so if you can help thanks in advance.
I had my hall replastered and painted last November and I'm having the problem showing in the pictures.
I'm worried it is being caused by water but where it is coming from I can't see. Hopefully someone can advise me on the potential cause but also how to remedy it. It's kind of unsightly and annoys the f**k out of me after getting work done. Nowhere else is affected except in that corner.
Thanks

Looks like water to me. You might have to at least take off the skirting boards to see if you can see or feel any damp.

The other thing to consider is if you dry clothes around there a lot. They could be causing some moisture.

Out of curiousity how long between the plastering and the painting? And when did it start happening?

it certainly looks like a lot of moisture.

what's at the other side of that wall - is it in the same condition?

Run your hand over it. If its dry, then it's salt rising to the surface ( plaster can "sweat" the same as skin. ) but there must be either water ingress somewhere thats driving the salt out, or an area with very little air circulation, hence condensation build up. You can buy plaster salt inhibitor and apply to the surface ( scrape and sand first). This will stop it reoccurring provided you sorted out the initial problem

We don't dry clothes there at all

I can't be sure when it started tbh. There would of been 3/4 weels betwen the plastering and the painting

the other side is the external wall and all seems fine there.

one wall feels damp and the other dry??

Is the "fuzz" rough?

we had this on our external wall which was caused by a overflowing rain gutter.
The wall on the outside looked perfectly fine and we only saw it when it was raining heavily.

In picture one it is soft and flaky

in picture, yes its rough

The rough one is definitely saly, the other may be mold but you definitely have moisture ingress somewhere

How old is the house
It looks like a dpc problem rising damp due to a break in the protective membrane that stops damp rising from the ground up .
You might have to look in to injecting a liquid dpc below floor level.
Did this problem occur before replastering.

Looking at the picture it looks like your radiator piping has been boxed in, as the is the area giving issues I would be inclined to remove the timber cladding to check the pipes in case of a leak.

Thanks, I'll investigate but I think I may have an idea of the cause

Update on this and opinions on what I've found will be appreciated.
Also thanks to all for your contributions

So outside the house, directly on the other side of the wall is a drain for the bath and sink in the bathroom. This was covered by a creeping ivy plant which I removed fully today to get a closer look. In the drain I can see what looks like a hole about a foot down. Now the drain pipe itself doesn't run as far down as this so is it possible that this is where water is getting in and causing the damp?
Any suggestions on how to fill the hole, bare in mind how it will dry in a damp drain with water hitting it. Of course I can also replace the pipe and make sure it goes beyond the hole.

pop up a pic and we will look.
usually better to replace a pipe than bodge on a patch
