Damp in bedroom

phil24_7

Have you been up in the attic and had a look towards the eves by the room in question? Check for damp/mould/shiny surfaces in that area. Also look for daylight coming in or try to feel for bad drafts in that area to try to localise any leaks.

Is it damp all over the ceiling or localised in one place. Is the damp in the ceiling by the external wall and at the same place as the damp on the walls?

This would indicate that water is getting in from the roof/guttering.

Is the guttering clogged with dirt/weeds etc?

No - it's definately originating from inside the house - from showers !!
The temperature is too cold (13 degrees this morning) and my wife will not put the central heating on
She believes that it is better to open all the windows and let the fresh air in - rather than using heat and the dehumidifier !!

What is the long-term solution ?

Insulate, air tighten and fit controlled, heat exchanger ventilation. Throughout the house.

Long term is find the source of the damp and stop it!

Shut bathroom doors when using showers/baths
Make sure any extractor fans in bathrooms work, are clean, & are being used. Make sure they run-on for some time after shower/light off.

If you dont have extractors, or theyve not got enough oomph, get a MVHR one
(they recover ~50% of the heat from the air they extract & use it to warm the air that they bring in to the room)

But cost £1500-£2000 - don't think so......

£300 more like - http://www.amazon.co.uk/KAIR-RECOVERY-SILENT-EXTRACTOR-ANTI-CONDENSATION/dp/B004VW3RGW - not recommending this one specifically but its doing the job you need. Yes if you go for a full house MVHR system it will cost thousands but using a decent extractor that also recovers heat should help.
