damp in the house!

Hi all, well I'm going to upload a few pictures so you can get an idea.

Damp is predomently coming through in the lounge bay window, however all windows in the house (bar bathroom) are like the window pic shown.

The roof beams are damp (as pic shows) and the felt is damp to the touch on the inside.

We're unsure of what's causing it, so I really need some suggestions. The damp is originating from the front right part of the house (lounge) as its the dampest area. However, the bathroom has a damp 'patch' it would seem, which doesn't tie in with whats going on elsewhere?

I've taken the pic with the mould before I treat it to keep a good record.

the last picture is of the bathroom.
First beams, two middle lounge bay.

Could it be cavity? Or front facia? New guttering was put on about 6months ago? Roof tiles?

It's a rented property and LL is trying to work out issue as well, but any help is really appreciated guys.

Thanks!

You need ventilation in your house. You have a condensation issue. Lots of warm humid air in the house meets cold surface = condensation. Its a lifestyle issue as much as anything else.

In the case of the lounge window I'm guessing you are drawing the curtains in the evening and trapping that warm humid air behind them. All that "damp" is down to condensation - nothing else IMHO.

as above. it looks like a classic case of condensation.

ok - thank you for your replies. -- Yes curtains are shut. Shall I just shut the blinds instead now?

So any pointers on what to do?

Does the house require more vents? I know the bathroom needs a better extractor and the kitchen also.

In the loft, what can be done to improve ventilation?

Its pretty obvious from the streaming windows that its condensation... are you drying lots of damp washing inside? that damp has to be coming from somewhere.. Do you ventilate the rooms during the daytime , open windows for instance?

no, we have a conservatory where all washing is dried, and we run a dehumidifyer if (in the case of -6 weather) we bring the washing into the kitchen.

also the house is empty during the day, work - school etc. So opening windows wouldn't be safe + when your home, who wants to open windows when its this cold?

Damp seems to originate from front bay window?
