We have recently (December 2013) had our windows replaced as our old windows were showing signs of condensation and also looking pretty tired. We went for quite a high quality window frame and glazing as we wanted to ensure the temperature within the house was at a decent level all year round. Unfortunately we seem to have unvovered a big problem. On all the reveals and ceiling there has been a steady increase in damp patches and build up of mould. The damp and mould start at the bottom of the window and work up steadily. We never had this problem with the old windows so we started to investigate. In 2009 we had our cavity filled with a breathable fibre. The company who did the job came out to look at the problem today as I thought we may have a 'cold bridge' problem, I didn't mention this as I wanted to see what they thought. The drilled several holes externally and sent in a camera. They said that the problem was that the window fitters had either removed some of the fibre or pushed it back and this was creating a cold bridge and subsequently the problems in the house. It does make sense and I have to say I tend to agree but im still not totally convinced and wonder if there are specialists out there who would be able to come in and give an impartial verdict and hopefully a solution?
