Condensation & Mould

.Ger

I have a old bunglow and in 1 of the bed rooms im getting mould on 1 of the walls and in bottom of wardrobe and under bed and anything left in the one spot long enough.

I was wondering what would be a good fix for this. i rang a guy in a company that deals with damp and Condensation and he said put kingspan on the wall that the mould is on ( this i can not afford) as price

The room does not have a vent so my plan is to put a vent in the room but where would i put it floor level or up high or on the wall that the mould is on ??

also did anyone ever here of http://www.thermilate.com/product-overview/industrial-coatings/anti-condensation-paint

any help guys would be great

Anti-condensation paint doesn't really work.

It sounds like you need a dehumidifier. If there is anything damp or wet in a room, a dehumidifier will dry it out if you close the door and run it for a couple of days.

yes a vent will help greatly about one foot below cieling height 4" diameter.

Check outside at this spot and around it during rainfall ( no shortage of that!) and see if there is a gutter overflowing down that wall section or water pooling against the wall. If it's old enough there is probably no dpc.

You want to treat the cause not the effect.

Couple of really knowledgeable lads here will be along anytime now...........

Best of luck to you.

Thanks guys

I do have a dehumidifier and it does clear some of the damp however it is not fixing the problem, also not cheap to run.

slavetothegrind) the house is old and it did not have any dpc so renevated it when i bought it 2 years ago and got a guy to inject something into wall that blocks any damp from rising and i dont have any problems with rising damp since. however the wall that the mould is on out side there is a pavement , i dont know if that is a problem

my plan is to put this vent in the weekend... now the wall is about 2 ft thick and blackstone any ideas what would put a 4in hole in that, my plan is to rent something out for the weekend.

thanks again in advance

I agree with slavetothegrind. Install a vent in the wall, (circa window lintel height).

You can hire a ("Ronnie") Corbet to drill a 100mm dia hole in a cavity blockwork wall. Solid stone is a different matter & would require a specialist drilling contractor - conc bore drill - can be expensive but worth getting a quote.

If the footpath is within 150mm of the finished internal floor level - then this could be the cause of the problem. Can you a photo of footpath & internal condensation?

Dehumidifier costs are cheap if you consider your health - even one Doctor visit and a prescription would buy alot of electricity!
Don't live with mould.
Treat the cause and then the effect.:)

How much would a good dehumidifier cost? and how often do you need to run it? each day? I've a similar problem and am thinking of getting one.

RKQ - here is the pictures hope this helps in the pictures you will see the footpath & internal condensation well the mould anyway

I rang the local tool higher place and a price for a drill and it is for stone and granite is €35 +vat for a day


Happynappy i bought my Dehumidifier for 80 euro and holds about 2 ltrs

Not a bad price, I see them in argos for 150 to 200 where'd you buy yours?

I could be wrong, and I'm not an expert, but I think you have bridged the injected dpc you had installed with those orange bricks you have stacked up against the wall.


you should never store bricks directly up against an outside wall because moisture can leach( correct word ?) from the ground into the brick and transfer through the wall.

It also looks like there was an air brick filled in under the window did you do this ? if you still have old timber floors in this room ( with a gap underneath them) you should not have blocked up the air brick.

The last thing I'd look at is along the apex roof line it doesn't look like there is much protection where the slate meets the top of the wall, there are sealing strips you can get to put along this edge it will also prevent any slates blowing loose in high winds.


Let us know how you get on

Happy nappy i bought it in B&Q about a year ago.

Fries thanks for reply, the old wooden floors have been removed and pour concrete in room, also the wall with the roof ladder outside it is the effected wall , and i will be removing the bricks thanks for that.

THANKS AGAIN

.GER Good luck with drilling through the wall , Take your time and dont put too much pressure on the drill. Apply gentle even pressure and you should have no problem.
Once you have the vent installed it is important that you rid the room of any mould that remains. Remember mould is a live organism (got that right) and must be correctly treated to kill it off .Your local hardware will stock what you need. Do not attempt to paint any walls until you have killed off all the mould.

well id say its gonna be a bit.h to do but it has to be done.

the effected wall is facing north so what wall is best to install vent ?
