Hi

I have had some tanking, chemical DPC and replastering done at a cost over over 2k. The stairs have been partially replastered but i noticed some damp areas and i peeled off the paper. will this dry out now underneath has been treated or has the damp company bodged it?http://i211.photobucket.com/albums/bb234/TBeckett100/damp.jpg

Can you clarify if the damp is new or was it there to start with. When you say partially replastered, were the areas that are now damp replastered? Chances are if you have now eliminated the source of the damp, the wall will dry out. Though if there is still another route for the damp to get in then you may find that you suffer from damp in different areas. Was the company reputable? If so why not ask their advice?

i am just a bit nervous about the house. The damp was there when we moved in but the reputable company only did 1,5m up each wall (sharp cut off on the electric meter). I thought it should dry out but wanted an opion really.

Thanks

How high above actual external ground level is the dampness manifesting itself? I am assuming it is higher than 1.2 metres at which point rising dampness is negtated by gravity? Have you any photos of the exterrnal elevation on the opposite side of the wall to the dampness?

the property doesnt have aback garden. at the rear of the property is the neighbour garden which is half a metre to 3/4 below the level. one wall ironically with most damp in the pic is the otherside of the bathroom wall which is tiled.

This may not be ironic, a lot of rising damp problems are misdiagnosed. I would start by checking the simple things like seals, grouting, embedded pipework, leaking cisterns etc.

I see this sort of thing everyday in my line of work and a lot of dampness is caused by these simpler things.:beer:

It could be condensation which often occurs in corners of cold walls - especially single-skinned external walls (in the photo is looks like there is the edge of a window on one wall so I am assuming it is an external wall).

Condensation is a very common form of dampness in buildings, but is a bit of an effort to explain. Basically it happens when warm, damp air comes into contact with cold surfaces (e.g. a chilled beer bottle!). The following sites give a better explanation specifically related to buildings:

Condensation problems can often be cured with better ventilation.
