Weeping wall

Basketman123

I have a stone-built cottage with the east gable built over part of a large stone slab. I am guessing that this is the source of the mould on the lower wall inside, as well as the moisture (small droplets) on the well inside, as well as the coldness of the room, and the condensation on my new double glazed windows. I am just wondering is there any solution short of knocking the whole gable wall, blasting up the huge boulder, and rebuilding. I would be most thankful for any advice or tips!

What is the:
Height of Ext ground all around cottage in relation to floor level?
Do you have a vent in each room and mechanical vents in wc & kitchen?
What insulation have u on your walls?
How is the cottage heated, is it heated constantly?

Hi Bryan,

To answer your questions:
That end of the house (i.e. the east gable) is situated on the slab, which is perhaps an inch or two above the floor level inside, so that there is an incline (ever so slight).
No vents in any room in the house. All other rooms are fine (i.e. not damp etc).
No insulation on walls. Merely plaster inside and outside.
We have installed central heating which runs on oil or mostly on the solid fuel stove (turf and wood).

Thanks for responding to my query!

1. likely to be part of problem - is there anyway you could improve the external drainage without moving the slab?
2. vent may help reduce surface condensation
3. this may be part of the problem - cold air high in RH condensing on cold surface

The slab would have to be removed with a rock breaker, I imagine; it is about 20 foot by 10 foot in size - no idea what depth.

Hi.what sort of plaster is on the inside and outside exactly..is it the original and if so what is it..if its been redone is it sand and cement?

It has been recently (4 months ago) plastered inside (conventional plaster but not skimmed - more like rough finish). Outside hasn't been plastered in years and is probably letting some moisture in. NOt sure if that answers your questions. Thanks!
