Hello,

Hopefully someone can advise me, is there any correlation between the whitening on the external brickwork and the damp internally? I'm looking to buy a property and don't want any costly damp issues.

Ana

Efflorescence is a crystalline deposit of salts often seen on the surface of concrete, brick, stucco, or natural stone surfaces. It occurs when water is present on or in the masonry surface. It sparkles. It's white, sometimes with a grayish tint. It flakes off the surface and is present only on the surface. It's actually salt deposits left behind by water.
I would not expect efflorescence to be apparent on a building of the age shown in the Photo.
It is present due to the introduction of water!
Looking at the junction of the top of the single storey roof and the right hand side of that roof where they meet the wall; there is no evidence of lead soakers or flashing having been fitted! There appears to be a mortar fillet, which would admit water to the brickwork over time!
I am unable to explain the presence of efflorescence on the face of the single storey building, but would want to establish that a DPC had been fitted.
Hope that helps.

Labourers not covering up bricks or sand properly and them being contaminated by rain water is the main cause of efflorescence. Once it's there it's there forever more I'm afraid and although unsightly it's not doing any harm outside. A going over with a stiff hard brush will help take away the white appearance over time.

Thanks for the replies. So the property does need some work doing regarding flashing etc. That gives me some leverage when negotiating the price.

Thanks
Ana

Looking at the water stain at the junction of the pitched roof the parapet wall and the rear wall of the house, I can't help thinking that it might be caused by overspill from the gutter, possibly too much water for the gutter to cope with and it's flowing straight over the end stop.

the gutters and downpipes have been recently fitted probly and so is the decoration inside probly recent. the kitchen will have more damp an condensationdamage on the walls like the bed room walls.
the kit might ave rising damp as well.
dont let this damp stuff put you off buying, its not mega to fix.
if you buy it come back here an ill tell you how to sort it out.
mortgage survey will be done anyway
