Heavy Condensation

susiewong66

i have had cavity wall insulation and loft insulation done quite a few years ago now, no survey was carried out prior to this to see if my house was suitable, which i see some companies now do?

since this has been done, my bedroom windows just pour with condensation, my walls around the windows and my blinds are balck with mould

is there anything i can do to alleviate this problem?
i feel as though maybe my walls need venting so they can breath perhaps?

I have double glazed windows, even if left on night vent , especially in my son's bedroom which is far worse than my own, it makes little difference to his window

if anyone can help with tips hints etc i would be most grateful

cheers

My house did EXACTLY THE SAME!! I was mortified as water ran down my walls

Then I read about the wonders of dehumidifiers ... I bought 2 (( not cheap but worth there weight in gold )) .. I have one upstairs and one downstairs .. And I don't have the problem any more.

I have them running all day.. And I haven't noticed a huge hike in electricity charges?

if you are planning on staying long term in your house you may want to consider something like this , which can get rid of up to 2+ltrs of moisture per day , or you can try leaving the windows open a bit , or as slinky has said get a dehumidifier , make sure you get something decent as the cheaper ones tend not to be of much use ,

If you have them running all day they would probably cost a good £1 a day each. We leave ours going on the low setting all night and costs a 50p extra.

The windows are now the coldest surface in the house, so that's where water will condense.

You need to look at sources of humidity - pets, drying clothes inside, showers, cooking etc. and ventilate.

Alternatively, buy dehumidifiers which provide an even colder surface than the windows to collect the water.

I have a bit of this problem, though not as bad it sounds, I have water collecting around the window ledges which sometimes forms a small pool on the window ledge. On cold days, I go round with kitchen towel and mop up the water in the morning.

I have vents which are permanently open but aside from leaving the window itself open there's not much you can do.

The best thing I have heard is indeed a de-humidifer as others have suggested. If i had it as bad as you that's what I would do;it's an expense but it can also be useful for drying washing.

For the area around the window I'd suggest mould remover - I have - dettol mould remover in the green bottle which you spray on for a little while, leave, rinse off and dry.

Is there any point in replacing the glass with the newer, gas filled glazing units?

Our DG is 24 years old. We only have a problem in our bedroom, presumably as OH gives off do much heat?

Never dry washing indoors.

It's not heat that is the issue, it's the water vapour he gives off when breathing. No simple way to limit that...

I've recently purchased a house with old wooden sash windows thats have been nailed and painted shut. Ventilation is a nightmare and sometimes when we have had a shower or put washing out the place can be like a swimming baths (although not as warm by any means).

Until we get our windows fitted I'm currently using a plug in dehumidifier. I wouldn't expect miracles in minutes but I do find it's helpful when left on for a few hours.

I've not been in long enough to work out what impact it has on my bills yet but I only have it on a few hours here and there per week.

I'm hoping the new windows will minimise the amount of condensation once we can properly ventilate the house.
