Guys, i need a bit of advice. I keep on getting mould growing behind the headboard and the picture frame and have to keep on cleaning it with mould killer regularly. It is on an external wall with no insulation due to the house being an early build.
Any suggestions on how I can stop this from happening?

Ventilation is the only cure.
More info required but at a pure guess is it an old house with solid wals and you have fitted PVC double glazing?
If so that is your problem.
-
Ventilation, heating, don't have your bed right up to the wall. We had it like mad ruined clothing and or wardrobe. We had to put extractor fans in kitchen and bathroom. Window vents in the windows. It can be a range of things
-
yep ventilation is key iv seen so many houses where people block ventilators and then wonder why they are getting mould problems also try keeping the bed away from the walls so that the air can circulate, but your first priority is to get rid of the mould properly
this is the stuff that we use at work, you would need to treat the whole wall and not just the bit thats mouldy and repaint

Top pic looks cool... keep it! :grin:

Plant some button mushroom spores, at least you get some free food then... How old is the property, solid wall? I had similar problems, as said ventilation is key, I've installed two extractors running on humidity stats, one for bathroom, one for kitchen, started digging out the front garden as its filled with soil (over a foot from ground level) causing water retention and not allowing the walls to breath much. Once that's done, I'll add an additional down pipe (no down pipe currently) as well and maybe a third extractor to an additional room, but there has been huge improvements with every improvement done, joys of Victorian build!
Check for external wall for moss growth, moss helps hold moisture in, dettol kills moss quite well from experience, which I was suggested by a civil engineer friend, with black dots, I know chemicals containing copper they hate, otherwise top tip is usually use a bleach/chlorine solution to clean the area, but still try and fix the original problem otherwise you will get the mould returning. I know on fresh plaster its very rare to see mould due to the high levels of alkaline from the lime, which mould absolutely hates.

There's a reason this is happening. Your house must be letting in water some place and its making the wall damp. You need to find out where and stop it or this will get worse. No matter what you do if its not stopped where its getting in it will just keep coming back. You could be looking at a big bill to fix it but at the same time as said above this stuff can cause real health problems. My dad was a joiner for 45 years I'll show this to him and see what he says in the morning.

I would get thermal plaster board put in so you have two skin barrier then re plaster it it could be the pointing on the outer wall has seen better days?
-
I'd start with the obvious.
Check external wall pointing etc.
Check if there's any water running down it from gutters etc.
Rip the plaster off.
Fit a damp-proof course.
Re-plaster
Ventilate.

thanks for the advice fella's.
this is happening in my 1st floor bedroom. no ventilation bricks so no blocking of them
i will clean the area using dettol as you have mentioned and will fit air bricks/ventilation.
the pointing on the outside wall is fine and as its an old house it doesnt have cavity wall insulation.
the bed is against the wall due to it being a small bedroom with upvc glazing (trickle vents are open)
insulated plasterboard seems like a good idea. i might aswell do all 3 bedrooms that have an external wall but do it one at a time, costs isnt the issue, its moving the cupboards/moving stuff and drying time/repainting thats gonna be a PITA.
-
the problem you have is condensation (you can see the run marks down the wall) not faulty pointing/leaking roofs as has been suggested if you had faulty pointing etc then it would not show in a perfect square behind your headboard it would show on the whole wall.
does the bedroom window often get condensation on it?? if it does you need better ventilation, do you have this problem in any other rooms in the house??
-
Hello mate have you sorted the problem yet, does this only happen winter time when its cold,do you wind the heating up high.Go up in the loft and check the underside of the roofing felt,see if you have water running down it towards were that mould is.
-
i'm thinking the problem is simply a cold external wall. mould will always grow on the coldest darkest spot. does it strictly collect behind the head board? or is it in the corners too?
as already said ventilation is key. pick yourself up a dehumidifier in the short term; have it on specifically at night, and if the humming keeps you awake put it in another room and leave your bedroom door open. speaking of which, do you sleep with the door open?
in the long term, insulation. baton the walls, use polystyrene sheets between the batons and then plaster board and re-skim. you'll lose a good 2-3 inches though if space is an issue.
