  • My building survey has come back fine (as it can be) on a mid terrace Victorian property -but it is suggested the property has rising damp. This has been measured using a moisture meter, there is no visual evidence as the property has been entirely refurbed new plaster etc.

    There is some damp in the cellar noted by myself and the Surveyor (as expected), but this doesn't concern me as I have already budgeted to get someone in to redo the floor membrane, concreate etc and tank/waterproof the walls etc, as this space will be for bikes and a workshop.

    I've asked my solicitor to enquire if any DPC was carried out as part of the refurb, the surveyor says there is evidence of chemical treatment at the back of the house. It's not a deal breaker, but I also don't intend to strip off brand new plaster to find out if there is an issue or not, so it might be something we have to keep an eye on and deal with later down the line if it is an issue.

    Has anyone experienced this and have any advice?

  • there is no visual evidence as the property has been entirely refurbed new plaster etc

    I think the usual view here is that rising damp / damp meters are all a bit of a con and a tool of snake oil salesmen.

    That said, if the property has been plastered really recently you have no idea whether there is obvious damp behind it that’s being covered up, and whether the DPC has been breached by shoddy workmanship.

    In the first instance you want to raise queries about the chemical treatment, plastering etc, and ask if they have any photos from before it was plastered.

  • I have pretty similar. It's annoying. Everyone you try to get to diagnose it is a cowboy and it's pretty much impossible to do non-destructively.

    Some areas where a possible problem was identified are no issue, some have got worse. We've done some temporary fixes but will need to be properly sorted when we redecorate.

  • Gosforth handyman on YouTube has been dealing with the damp issues in his 1930s new house over the past few videos.
