Damp internal wall

Postby d4074u » Mon Jan 12, 2009 1:17 pm

We have just moved into a 100 year old end terraced house, and were aware that there was some damp before we moved in. Now we are in and have had a chance to look at it properly it is apparent that one of the worst affected areas is a dividing internal wall between the kitchen and the lounge - this wall isnt on a boundary with an external wall at all. However there is a shower installed on the same wall on the floor above, in a similar region to where the wall is most affected. Does anyone have any thoughts on whether the shower could be the cause of the problem, i.e. could there be a water pipe running along the wall which has potentially burst or anything? Any ideas how i would find this out, or other causes of internal damp are much appreciated!

Simply Build It

Its quite likely that the silicone around the tray is defective or the waste is leaking under the tray. Also check the tray is not damaged. I looked at a damp problem last week and found a split in the shower tray. They have been using it like that for a year now!

I am new to this site, and would welcome advice on the following:-

I have damp patches above my bathroom window, internally, and this has spread slightly on to the ceiling.

Is it possible to paint over the wallpaper (it is still stuck to the wall and is not peeling).

I do not want to strip the paper off totally in the bathroom as the patch is only in the top corner of the one wall.

Can i also treat the very small patch on the ceiling (this is currently painted, not papered).

I have had the problem cured re. the damp coming in through the stone wall. The felt on the roof was rotten, and has been replaced by a reputable builder.

Unfortunately the damp is in the stone wall. Do i have to get a dehumidifier to get this damp out?
