Condensation issue

[tmk2]

Hi I am having issues with one of my bedroom windows every morning it is covered in condensation quite badly, it is an east facing window and the room backs onto the bathroom. most of it goes if I leave the window open while I am out but this isn't ideal and tip on how to limit this build up?

slightly off topic, but do modern sealed houses have problems with condensation? I've been plugging draughts in my old house and the room temps have shot up at the expense of a little condensation. As modern houses and windows are sealed do they rely on a trickle vent in each room and if so doesn't that create a draught?

Modern sealed house usually aren't sealed once the plumber and electrician have finished their work which always involves smashing a hole through something. Often older terraced houses are more efficient if the owner owns a mastic gun.

Ideally, and probably coming to new houses here soon, you'd have the house more or less airtight with ventilation provided by a heat recovery and ventilation system.

You can retro-fit them but their effectiveness is lessened in a leaky house.

I have a professionally-fitted double glazed window in my bathroom and when it's sub-zero outside it still gets condensation. It's just a function of differential temperatures and humidity.
