Damp Bedroom

Hi There

Just wondering if any one can advise on how we should tackle an issue with a damp room.

We live in a bungalow on the east facing side of a steep hill around 20% gradient.
There is often a musty smell in the main bedroom which is on the north west part of the house.
We have a hydrometer and can see readings up to 80% so use a de-humidifier to reduce the moisture down to 50% (I read that was normal level), but once we turn it off it is quickly back up to 70+

We have a Vent and 2 windows at other times.
There is a wardrobe on the external wall and while we dont see mould but get a strong musty smell from clothes and carpet.

Can anyone suggest anything? what to eliminate or who to talk to?

Thanks

Is the room occupied? Ventilated?
Is the floor damp?

It could be moisture from the environment or it could be from occupants. These causes require different solutions.

Thanks for the reply

The room is occupied. and is ventilated with 2 windows and vent. we are in a bit of a valley of air flow is sometimes limited.

The floor isn't damp.

I think it is more the environment rather than occupancy.
I was thinking of removing the wardrobe from the external wall and put it on the internal wall. would this help?

Another vent would help to i think.

Thanks

Moving the wardrobe won't address the issue I'm afraid.

If the floor isn't damp if be surprised if it was environmental. A couple sleeping in a room can really raise humidity if ventilation is poor. Also, is the room ensuit? If so, is the ensuit ventilated, particularly when the shower is in use.

Next step would be to take some humidity readings in other rooms, just to get an idea of what is going on in the rest of the house. Id then take readings in the problem room, then run the dehumidifier to get it back down to the rest of the house level and while the room remains unoccupied measure humidity 24hrs later.

If it rises significantly, then you have an environmental issue. Otherwise it's a ventilation one.

There is a back to the wardrobe. I will make a small hole to see. It could be mouldy there but that would have zero ventilation so would expect it to be worse.

The house is mid 90s build.
Gutters are OK. Cleaned them about a year ago. Could be better of course.

Not sure what you mean by constitution or gullies? But condition is fine I think. And gullies is a gutter right?

Thanks a lot for the response

I know you say there is a vent, but have you checked it to see if it is clear? Also - are the walls painted or papered? I’ve seen horrendous dampness in an old house before behind wallpaper that you would never have guessed from looking at it.
