I am absolutely desperate for a solution.
We moved into our cottage which has stone walls 2 years ago.
•In our main bedroom we had the external walls internally insulated.
•When we moved back into the room we were waking with streaming condensation along the reveals with a 6• temp difference between the reveals and adjoining walls. This damaged the oak window board.
•Found the windows had large gaps either side of the frame so has those filled.
•Took up the tiles from under the window board; had it levelled and any gaps filled.
•We have tried having the windows open, door open, windows on latch with no joy.
•Our son slept in this room last night while we're having work done in his room and we've woken to the exact same problem.
What the hell do we do?! There's not enough room depth wise on the reveals to have insulated them unless we chip them back so there is enough room and then re-plaster (again!).
Do we need to check the windows again externally? Do we need to removed the render on the outside of the house to allow these bits of reveal to breathe?
Do we get someone in to give us another option and if so what type of company? We've had handy men, plasterers, builders etc all give their advice.
Please help I'm unashamedly begging for a solution
