External Bricks Discoloured and Damp Inside in Kitchen Extension

[sadjonvee]

I have damp/mould appearing at three locations in a kitchen extension (all around 9/12 inches up the wall) and on the outside wall, the brickwork is lighter than elsewhere - red brick that looks greyer/dusty in appearance.

I'm assuming that damp is getting through at these points, and my question is what I can do to a) remove the damp and b) stop it returning - is there a treatment I can apply to the brickwork to protect it?

The interior wall is not badly damaged - mainly just looks like some black mould spots, and there is, apart from the discolouration, no sign of external damage. So I'm hoping someone is going to say "Oh you just need to brush this on and everything will be perfect again..."

;-)

Any advice would be really welcome.

thanks

Use neat bleach on the wall to remove any mould, And a dehumidifier to dry out the wall.
On the outer wall, paint aquaseal silicone sealant on the wall,
