I have a damp problem in a house I have refurbed,and am unsure as to whether it's condensation due to poor circulation,water in gress trhough the roof,or somekind of penetrating damp via the cavity etc.
I need to have a more detailed look myself,however would like someone to give a professional opinion on what it may be and what do do about it.
I am unsure on who to call on,as I would rather have an independant view as opposed to someone looking for a job to fix it.
who would be better?
damp specialist (groan!)
