couple of things...

[nickkinix]

Hi all I'm hoping someone can advise me....
I had a chemical dpc injected along the outside wall of my end terrace house in august. The walls however did not have the plaster removed as I was told it wasn't necessary (by Rentokil who did the work). The walls are still wet - especially where they used the tool to probe into the wall to check the damp levels (there are very obvious circles around the areas maybe 4cm in diameter.)
Please can someone tell me what to do as this is driving me to distraction!!
Secondly, I was about to hang a new blind in my bedroom window this afternoon when i noticed a vertical crack about and inch and a half in from the window which runs the whole height of the window. The crack is approx 3mm in diameter and the plaster has started to come away from the brick behind it.
This is my first house and I feel I was well and truly shafted, as there are numerous other things the previous owners covered up in order to sell. If someone can give me some advice Id be really grateful.

Hi,
Damp isn’t quite as straight forward as some damp proofing companies may suggest. Damp is often mis-diagnosed and treated with chemical injections and creams.
In order to offer advice I would need to know a little more about the building itself.
How old is the building?
What construction type is the building? (I.e. double skin with cavity/ solid wall brick/ solid wall stone and rubble?)
What type of mortar was used in the construction of the building? Lime or cement?
Has the building had any finishes applied to it which are not original? I.e. external render or paint or internal tanking or plaster?

The cracks and other defects could be attributed to the damp in the structure too. It is hard to say without a structural engineer assessing them.

hi there, I also posted this under 'building' everything I know about the house (inc pics) are under that thread.
Any help is gratefully received!
