Builders Question Advise

My daughter is in the upstairs back room (small room) which has the outside wall.

She says that the wall is very very cold of a night lately and one of the pillows she had down the side of the bed against the wall was actually wet with water moisture.

I said to the wife I'd ask what it means / what to be done.

In my limited knowledge I said I think the wall needs re-pointing.

It is a 1930's house, so single brick wall I'm sure.

I'm guessing if it's brick there will be a cavity. Sounds on the face of it to be condensation. Ventilation and heat are your friends here, maybe even a dehumidifier before doing anything too drastic.

Get a builders report on state of wall. And roof and guttering above. If gutters are blocked or have holes in water can rundown wall and get under the rough cast etc. Sometimes fixing the gutters etc and drying it room can cure it

I was, of course, making a basic assumption there were no obvious gutter/roof leaks etc. How much ventilation does the room get ordinarily?

I was surprised to see the 30s house we bought a few years ago was single wall, I thought they were double walled since Victorian times.

Yup could be condensation too. Single brick walls without cavity are inclined to go this way.
celotex made external boarding to fix these issues. Not cheap but should dolce it if that's the problem

We had this problem in a 1930s house which had solid walls. One wall was always cold and wet. After trying all sorts to cure it we ended up fitting a device in the loft which blew air from the loft down into the house. This worked so well that there was no condensation on any window in the house. We have since moved so I can't check what it's called but it was fitted by a company called Peter Fox

Internal insulating wall lining easiest to fit quick and not expensive. You can then investigate other options if needed.

When I converted half of my double garage (single skin) into my "cave" I coated all the internal walls with Synthaprufe before adding all the insulation. Have had no damp or condensation at all. In fact the other half of the garage which was alway wet inside in winter is now bone dry....not sure how that works, but heyho. It could be all the fibreglass insulation over the ceiling of the cave which is at rafter height. Coating was a filthy and arduous job, but worth it.

Was that a positive input ventilation unit ?
