How to deal with black mould on walls.

[faithhealer]

HG mould cleaner is excellent for removing mould but definitely need air movement

It is good stuff Faith, but as others have suggested, extractor fan is needed.

external walls are only ones effected by mould this must indicate something that needs sorting first

do you guys think that the cavity wall insulation could have started the problems here in this situation then?

I've been toying with the idea of cavity wall insulation in my house but I won't bother if it will start creating damp and mould.

 

[jay]

hard to say without seeing but sounds as if in this case there is an issue that needs attention cavity walls are fine if the outside wall is waterproof same goes with solid walls the aim is to keep moisture out on the outside not try to stop it on the inside

take care

When did the mould 1st appear ? After the insulation or before? Is it in just one area ?

 

[Mouldy]

can that stuff be tiled over mouldy?

I see no reason why not, however as has been said by others you need to rectify the reasons for the mould being there in the first place.

use a sander first on the mould then scrub with bleach,install an extractor fan that comes on with light switch and also an air vent on your window wall if possible,that always solved some scary bathrooms in the past.

The mould grows more on the external walls as they are slower to dry out as they tend to be cooler.

GRR dont worry too much about the damp from cavity insulation. The 'bridging' of a cavity is not that common a problem. Have a read up on google. Id have it installed as the saving in bills can be huge

You have a new house Liz... your cavity walls should already be insulated..?

Scottley, our bugalow is cavity insulated and we have all sorts of issues now, although not al can be attributed to this. Looking to install HVHR to cure the problems.....

Daveeeeeeee, it was built by Barratts! apparently they didn't spec any dpm over the concrete ground floors yet all houses on the estate have them. so I wouldn't be surprised if they had no cavity insulation. I'll ring Barratts and ask them how they built it. :lol:

 

[DHTiling]

It would be regs to do it Liz..

 

[Scott]

Doesnt mean it was done though! You can get a liquid DPM to put down if it wasnt.


Mouldy, did you have the insulation put in?
