Hi all, was down with my niece today & noticed the inside wall of front door all lumpy & damp looking . She bought it last September . It's 79 yrs old single brick no cavity. When she bought it she fitted new composite front door & had the attic insulated with the Scandinavia expanding foam thingy. The front door opens straight to the stairs so was wondering would there be enough air getting to the wall . Pics attached.

What size is the roof? You could get spray foam put on it... The shed roof
