Serious condensation questions

worriednoob

Hello everyone,

I've been reading a lot of threads on here and I'm very confused as to what to do with the condensation problem in our house.

We live high on a hill, so there is a lot of moisture outside. Our neighbours have no issues, however we seem to have a lot of problems.

Just to be clear, in summer we have no issues anywhere.

In winter some rooms - our kitchen, bathroom, hallway, backroom and 1 bedroom have zero condensation/moisture on the windows.

However, 3 bedrooms and our living room have lots of dripping condensation in the windows which has to be cleaned using a squeegee every morning.

My suspicious is dodgy double-glazed windows, because the condensation on the windows starts from the bottom edges of the white plastic & black gasket and works it's way upwards.

It get's so bad that even the plastics become wet with moisture and water is dripping.

Can it be faulty window gaskets? If so, how do I replace/fix these myself?







Thanks for your help.

Any

Are these the occupied bedrooms?
Sleeping human creates a lot of humidity. Cover on windows traps the colder air from the window and as we breathe creates a vacuum for collecting condensation.
We have the same problem, but only in the occupied rooms.
I clean the windows with the Karcher and it gets better for few days-as I am actually removing the water, and also we bought dehumidifier for the living room.

I would suspect not enough ventilation in occupied rooms.

Are the windows and internal doors always shut when those rooms are occupied?

Thanks for your replies guys. Yes the rooms are occupied, but then so is the kitchen, bathroom. The windows are not closed all the time and the internal doors are open vast majority of time other than at night for privacy.

I just don't get how rooms such as kitche, bathroom are used a lot and don't have any moisture problems, yet bedrooms do. I also want to say that on some occasions we have zero condensation based on what the outside weather is. This is why I'm suspecting that it might be the window seal/gasket.

Of course night time is the time when your putting the most moisture into the bedrooms.

If it's a case that human breathing is the cause of bedroom condensation, then why have I also got it in my living room too?

can i ask when you have your heating on in the house this is not a double glazing issue this is a heating and ventilation issue i see it so many times .I advize people to keep there heating on constant and turn it down a few degrees and this very often sorts it out . Do you use a gas fire . i would hazard a guess and say that your heating comes on 1-2 hrs before you get up and the same before you go to bed and if out at work is turned off and comes on an hr before you come home . I also see people leaving there heating off all day with windows open wide then having there heating on a few hrs in the evening

Because, I suspect, you and your family spend quite a lot of time in the evening in it?

Ventilation is usually the solution to condensation problems. (or removing the humans )

Martin, your right that we do spend more time in the room than other rooms, but it's already pretty drafty and anymore ventilation and might as well sit outside.

Sorry, but I didn't see your reply earlier. Your spot on regarding the the way my heating comes on and goes off. Every morning it will come on from 7am to 9am and then again at 6pm to 8pm. Although we have gas fires in both living rooms, we don't use them as the central heating is more than enough in the house.

I would like to add a bit of background info though....This is a semi-detached part stone/part pebble-dashed house. It is east/west facing and some rooms are more colder than others. A friend has said that I should get polyurethane foam pumped into the narrow cavity because this would warm up the house and thus should reduce the condensation. I am not so sure, because I've heard a few horror stories about insulation doing more harm than good, but I would like your opinions.

Insulating your house is not a fool proof way to solve the problem. What you need to do is reduce moisture production and move the moisture and get rid of it. Have you considered PIV ventilation?
