Condensation runoff

[tabernacle]

Hi,

This is my first post on the forum, but I've enjoyed reading the threads on this site for a while.

I'm posting on behalf of my mother-in-law, who is having a problem with what seems to be condensation runoff from the windows in her roof.

Here are some images of the runoff:

I'm not sure if there's a way to stop the cause of the problem. She keeps windows open a lot to try to avoid condensation, but this hasn't helped.

I'd really like some advice about how to stop the water from running down the walls. I was wondering if there's either a device that could collect the water before it runs down the walls, or if there are other window units that could help?

Thank you in advance for your advice. As you can probably tell, I'm certainly no expert! Just hoping to help my mother-in-law.

Thanks again,

Tim

Needs adequte ventilation, opening a window sometimes is not a solution, you don't breathe sometimes. Constant moisture output requires constant ventilation.[Hope you friend is not drying washing anywhere in the property.]

Thanks for your reply, but especially as it's getting colder now constant ventilation isn't a possibility. Is there any sort of device that could be fitted near the frame to collect the water?

Unless ventilation is maintained then condensation will occur.

Are they double glazed units, Tim?

Yes, I'm aware of that. Like I said in my original post - I don't think that the cause can be resolved. I am therefore looking for a way to manage the problem.

Hi,
Thanks for your reply. She thinks that they are. We'll probably be over there at the weekend and I'll be able to check

Hi Burnerman,

Apologies for such a long delay in replying. Yes, they are double glazing. We got her a scoopy condensation squeegee, which helps a bit. Do you have any other ideas for managing the problem?

Thanks,
Tim

See if you can fit trickle vents.

Hi Andy,

Many thanks for your reply. Unfortunately there is nothing to attach the trickle vents to. As in the third photo, the glass goes right to the edge on all of the units. I'm certainly no expert, so you might be referring to a special type of trickle vent for this situation - if so, Id really appreciate a link to them?

Thanks again,
Tim

How about a dehumidifier?

Hi Gazman,

That's a really good idea. I don't know much about them so will do some research. I'll have a look around to see if I can find one that's small enough and cheap enough for her. Do you have any recommendations?

Thanks

 

[Gazman16]

No particular recommendation, You can get them fairly cheep on ebay though.

I had a conservatory on a house I had previously let, and the last tenants had allowed the whole house to get damp. During the winter, as I was drying the whole house out, the conservatory acted as a magnet for the condensation. I found that desktop fans helped move the air around, warming the cold glass surfaces and the condensation stopped. The humidity was lost with ventilation and extraction.

If possible, get used to slightly lower constant temperatures and not intermittent heating in the room, create air movement and only ventilate for short periods when the air outside is significantly less humid - not when the pavements are damp from rain, and not when there is mist and fog. Frosty mornings, sunny and windy days are good.
I have to say that opening a roof light in driving rain - constant ventilation - is a no-no. It also will significantly chill the room, which will create more condensation when the room refills with humid warm air.
