Condensation issue.fitting fan/brick?

[Deleted User]

Hi All,

I wonder if anyone can help.

I have a condensation problem in my bedroom.

The outside walls are very cold thus causing condensation when I sleep.

I have left the door open/heating on low etc and this works OK.

I would like to fit a fan/vent to let some air go around the room so I can shut the door and keep the heating in etc.

Can anyone advise the best way and cost etc.

I have thought about insulating the cavities but they wont do this unless all the flats in my block agree.A long process.

It mainly occurs in the corners and at a very low level but would rather get it sorted now as its my home.

Much appreciated,

Chris

Do you have old style windows that haven't been changed in years?

The most effective way to cure condensation without loss of heat is a de-humidifier.

A fan/vent will work but by definition it will involve loss of heat.

Have you tried sleeping in the day instead when the outside walls are warmer? Seriously though, I think the dehumidifier is probably the best solution in this case.

Another option (although not great) is to stud the wall out and fit insulating kingspan and plasterboard, you'll lose a couple of inches of space but the new inner wall won't be cold anymore and the kingspan should prevent the heat from hitting the old inside wall and then causing moisture within the cavity.

You can get anti mould additive you mix in with paint, I used that and it stops the mould. I also use a dehumid as well and we have cavity walls here.

I have a dehumidifier for my bedroom and it works a treat. I only have it on during the day. You will be amazed at how much water they produce.

Yes I do have oldish double glazing but they have trickle vents which sort of help.

I do have a dehumidifier and it picks up zero water although I only ran it through the day and not when i'm sleeping as its noisy.

I have one of those salty bricks next to my window that catch water from B+Q and in about 6 weeks it has a litre or so in.

I know some vents give a draught but can't you get adjustable vents?

Thanks all.

If it's condensation on the windows, you could try one of those window vacs. I think you can get quiet dehumidifiers too, but I don't know whether they're totally silent. Generally, they're gonna be most effective when the when the source of water (you) are in the room. but I'd guess if the walls are getting damp, they they'll be good in the day too.

I generally don't have the problem, as I'll sleep with the window slightly open except for on the very coldest of nights, then close it at some point when I wake before the heating comes on. I never feel cold under goose down.

Window vents in my experience don't allow much circulation, but perhaps it's just mine.

We had a damp inspection for condensation - similar issue. They recommended we get a passyfier vent fitted in each bedroom - they are designed to let out damp air without loss of heat.
