I just bought a new house and although the survey and home buyers report were staisfactory i am very unhappy that the inside of the windows in the conservatory keeps misting up. i asked a heating expert for advice and he suggested turning off th radiator, i have done that but the misting is still present though not as bad as when i had the radiator on . I have the same problem in the bedrooms upsatirs but to a lesser degree... Im depressed about this pls help! ( i recently asked a joiner to check the seals and he says they all seem fine!
