Hi I'm new here. Just wondering if anyone knows what these dots are? I'm thinking dampness in the wall as it's been stormy last few days. Had Velux replaced during the week and got installer to look at roof. Appears to be no flashing in certain areas so figure rain is getting in...Please see images. Any help or advice would be greatly appreciated, thanks

do you hang wet washing over radiators or around the house?
 
We sometimes hang clothes off clothes horse but that's on third floor. Far away from issue. This is our kitchen/living room wall so hottest room in the house. We were told by engineer before buying house that that wall had slight dampness in it...

Why are the dots at regular intervals.

What is the wall construction / plaster type

I don't have any information I'm afraid to say on this. We only moved into property recently. My guess is dot and dab is the reason for the dots at regular intervals
 
you say it is the kitchen and hot. Is it also humid? How is the room heated and ventilated?

to me it looks like condensation where the dots are in contact with the cold wall behind. Is it an external wall? It could also be that the wall behind is wet due to leaking pipe, gutter or rain penetration, but it is quite a large area.

Is it a ground floor extension?

show us the other side of the wall please.
 
Thanks John for reply. Really appreciate it.

I will send on pics. Kitchen is been heated more than usual as it's cold at the minute and is open plan small kitchen/living room. Ventilation seems good however we have not been great at opening window to let house breath as the weather has been bad recently. The wall is external on other side. Neighbours garden so I took best photo I could take incognito.

The dots have died down a bit since yesterday but still there.

there seem to be some pipes in pic 4 but I don't know which way is up, or how they relate to the wet wall. please explain or take some more tomorrow. Stand back and take a wide pic.
 
It's neighbours garden so just had to get a small ladder and took pictures of Pipes. There was so moss in pipes which I've since removed as much I can reach.

I'll send you on pics from ladder and from above from bathroom window which I've circled in red.

Thanks foxhoke for extractor fan advice. Usually always put it on but come to think of it maybe slipped my mind last night when cooking.
 
those gutters clogged with moss are probably causing water to spill down the wall.
 
OP,
you seem to have an older house with some difficult building details.
there's a number of glaring faults in what your photos show.
house humidity is possibly the least of them.

there's a disconnected down pipe from the gutter - the square, black plastic pipe.
some of the roofing detail you show looks shocking, & if its not leaking now it will be sooner or later?
pic number 3 shows a very rough "Velux" install, & a strange, rough looking verge.
the yard wall butts up to the kitchen, and could be transferring damp into the kitchen wall?
whats the purpose of the soil pipe (in two kinds of plastic) near the down pipe?

the wall in question was probably rendered outside and the kitchen D&D'ed inside to somehow help with the damp penetration - its not worked.
read up on here, using the search button, to understand more about your situation.
 
The door reveals (post #7 first image) look rather small to me as if we are looking at a solid, one brick thick wall. It appears to me that whatever fixings were used on the wall, that they are transferring the cold through and condensation is forming as a result.
 
There is some good pickups by Bobasd and noseall. Looking at the photos, after reading their comments, I can see exactly what they mean.

i.e.
i) Appears that the walls maybe single skin block or brick. this would makes them poorly insulated and more susceptible to water penetration.
ii) The rain water downpipe is separated and running onto the top of the garden wall that abuts the house walls that are now showing the marks.
iii) The garden wall appears to have been attempted to separated with some plastic DPC but it stops part way up and with the rain water discharging directly on it and a possible single skin wall, that could cause moisture penetration.
iv) The gutters were blocked you have now partially cleaned need to clean out in full.
v) The roof and/or rooflight flashings do not look to be complete or present or not in the best of condition.

i) is hard to resolve without rebuilding or insulating internally and loosing some floor space.

I would concentrate on ii) to v) which may help resolve some of the problem or help prevent things worsening.
