Draughts in Exeter: ventilation and humidity
Humidity, dew point and ventilation in Exeter homes. Tell us which rooms are worst and at what time of day — that pattern usually identifies the cause before we arrive.

Air holds a finite amount of vapour at a given temperature. Cool that air against a cold surface and it reaches dew point, at which moisture leaves the air and appears on the surface. The surface is the messenger, not the cause.

Household moisture output is larger than people expect: drying laundry indoors, unlidded pans, long showers and unvented tumble dryers each add litres per week. Trickle vents, background extraction and a short daily purge move that vapour out before it condenses.
Measuring relative humidity with an inexpensive hygrometer over a week tells you more than any single morning's observation. Readings that sit persistently high point at ventilation; readings that are fine while one surface still runs wet point at that surface's temperature.
Draughts Exeter: ventilation and humidity
Sometimes it is the whole answer, sometimes it is half of it. Ventilation controls how much vapour is in the air; surface temperature controls where that vapour lands.
