Condensation on windows in one room only

becciboop

Hi all, we have condensation in our bedroom on the windows, this is dripping down and causing dampness on the walls underneath. Does anyone know how we can fix this? I've opened a window but whilst I am at work I can't do this everyday. Any help is appreciated!

Thanks

If you are getting condensation in that room only it is presumably the moisture released from your bodies as you sleep, breathe and perspire.

Is it a cold or north facing room?

What heating do you have in the house and in the bedroom?

Do you have an ensuite and do you take late night baths and showers or anything else that is contributing to the humidity levels?

Is the bedroom unheated or kept quite cool.

Is it well ventilated?

Is the window double glazed?

You need to reduce the humidity, increase the temperature or have a better insulated window, or a combination of all three.

You could increase the ventilation by leaving the door open.

Leaving a window open might be making it worse by allowing too much cold damp air inside.

You could try a dehumidifier.

You could lay a towel or moisture absorbing stuff on the inner window sill.

Try Rain-X Anti fog.

Sorry to hijack the thread but we have similar in the bedroom (thanks to previous posts on here, got lots of good advice to deal with it) and I've seen this mentioned a few times. However, I wondered if it was actually better to leave the moisture to gather on the window? If you use a product like this to prevent it, will the moisture remain in the air or would it, for example, gather against the cooler walls of the bedroom instead? I'd rather wipe water off the window daily than cause issues with the actual walls if you get me.

Its a north facing room yes. We have central heating and one radiator in the bedroom which is on a wall (but not under the window). We have double glazing. We put the heating on of an evening and morning, and in the morning the window steams up and condensation appears
There is no air vent in the room, so we are opening a window.
Do you think fitting a vent will solve it?
My boyfriend tends to shower of a morning and the bathroom is not en suite, I tend to shower of an evening.

Might not be for you, but some people use cleaner link below to remove condensation.

I am assuming the condensation is there in the mornings?

Do you sleep with the windows open? Try having them open at night, that should make a difference.

Depends how cold the walls are compared to the ambient temperature in the room. Do you have cavity wall insulation?

No, we have solid walls rather than cavity walls.

Yes, its there in the morning, would rather not have windows open but may have to. Its leaked down onto the wall below and the plaster is ruined, its coming off the walls. I will have to get someone round to check the windows are sealed properly too as it has really damaged the wall, surely it can't just be from condensation if the walls are that damaged. The rest of the room is as dry as a bone though, no wet bits on any walls.

Hi there,

Sorry to hear about your condensation problems. Would def suggest getting the double glazing checked, especially the external seals.

I've had this problem for the past 11 years, and have heard every excuse in the book about it's the way your family live their lives. Too much moisture, do you dry your clothes on the radiators, do you open the windows when you have a bath/shower, not enough ventilation, open your windows more, open your windows while you've got the heating on, it's your fault, it's not the windows it can't be...blah blah blah I've heard it all.

Having been back to the company that supplied and installed the windows many times over the years, we finally managed to get them to agree to replace the external seals around the outside edges (white mastick stuff, you get the idea.) Turns out they were never properly sealed at the original installation.

There were small gaps in the sealant which have been allowing the cold in so that the inside pane of glass is not insulated from the outside one. So every time we go to bed and funnily enough breathe out, any moisture from that is condensing on the windows which are so cold.

New sealant, problem solved overnight. I don't quite believe it. Double glazing which has been properly installed and sealed correctly should be able to cope with a normal family breathing while they are asleep. This is not an unusual situation.

And trust me, no-one I know takes more care to limit moisture in their house than me.

Good luck with it, I know how frustrating and soul destroying a situation like this can be.
