Consider condensation as a symptom and not a cause of home humidity being too high, so, if there’s condensation happening on windows, the first step we’d suggest is to get hold of a hygrometer or humidity meter or monitor to test the level of relative humidity in the home – because ironically the higher performance the home gets, with air barriers and better windows and doors, the …
