Approx. 5 yrs ago my end terrace sandstone property had a complete renovation grant on it.
Part of this was an injected damp proof course.
The kitchen (2 outside walls) continues to show damp. All the plaster round the sockets had blown. I got in another plasterer to repair this damage (oct 2010). I now have white crystals growing on the plaster around 1 socket and also under cupboards from ground level. The new plaster round sockets also looks as tho' it is cracking again.
Yesterday I had a reputable boss of a building firm in to assess the problem. (All the outside of the house had been re-rendered and painted no obvious water incursion).
He acertains that you can't use injection damp proof on sandstone houses and the kitcen should have been tanked! This involves all the kitchen being pulled out again and starting from scratch.
The local council authorised the builders who did the original work and we are awaiting their reply.
When we asked the original builder to return there was no contact.
This has been going on for so long with unpleasant damp smells in the kitchen.......I am wary of being ripped off again but am sick of the mess.
How can I be sure what is correct.
We actually had the council back who did a test and said the wall was dry.
We have already had the plaster hacked off once after original job.
Thank you in anticipation of your experience.
