Is there a problem with the actual fitting of my windows?
Hi, There is a build up of condensation on the walls around all of the double glazed windows which were fitted before we purchased the property. It is so bad that there is clear evidence of water and if not wiped weekly a build up of black residue along the walls and the edge of the window casings; top, bottom and sides.
What can I do?
