Water Patches on Roughcast


New Member
Guys - As you can see from the attached pics, I have what looks like a water stain on the rough cast under my window. I have had this stain for a few years now, I would say,it is less prominent in the summer but still visible and I would also say its getting wider. I initially thought it was water getting behind the roughcast, if this was the case I would have expected the roughcast to start breaking off during the winter, this has not happened. The house is a bungalow with a suspended floor. On the other side of the wall is my kitchen, there is nothing visible and no damp / strange smells in the kitchen, what is interesting is that the built in Fridge and Freezer is on this wall, don't know if that would make any difference or not. The area that is effected, also does not get a great amount of sun light. Wondering if any one has any idea what is causing this and how do i fix it?

Many Thanks
