    Damp & solid walls

    Not sure which forum section to put this in, so apologies.

    Currently buying a 2 bed terrace up north. Sign of damp in one corner on first viewing so engaged a damp specialist to do a report/quote.

    Property is actually riddled with it.

    His recommended method is all internal plaster off, repair/repoint as needed, membrane and then replanted.

    I asked if he could put me some thermal insulation in (kingspan etc) and he replied that it wasn't a good idea as the wall would sweat.

    Do others agree with this? What if anything can be done to improve the insulation on a solid wall Victorian property please?

    Thanks in anticipation

    Who did the survey? If this is a damp proof company you'll find that different companies give totally different reports, none of them likely to be accurate.

    Is there a visible damp proof course?

    Personally I'd probably look for a different property if the damp is really serious and there is nothing obviously wrong to correct it.

    If determined to buy ask a builder about external render - see https://www.homebuilding.co.uk/how-t...ne-wall-homes/ Edited to add - be warned that this doesnt come cheap.

      Thank you. Report done by a guy who runs a damp proofing / plastering company.

        I would batten out the brickwork and screw on insulated plasterboard. No idea if that would work though.

          was it damp or salts in the plaster? what type of meter did he use to test? if it was a double prong type that measure resistance then to be honest the survey as pretty much a waste of time as it doesn't measure damp it measures a flow of electricity through a conductor, which in this case was plaster that may or may not be subject to damp.

            Best to cure the damp first
            IWI is a complex subject and depends on your situation regarding exposure of the outside, brick permeability, construction technique
            many regular builders and architetecs are afraid of it
            you will find better info on forums about green building.
            Check out the superhomes website also
            or get an independant advisor who knows about this kind of work

              The property could well be riddled with damp.

              It could be a leaking pipe.

              A damp remediation firm is very unlikely to give an impartial inspection of a property.

              A damp building isn't, in itself, bad.

              Are you having a Homebuyers Survey done? Or just a valuation? I would ask a local Building Surveyor to inspect and advise on this specific issue. Along with suggestions for repairs / remedial works.
              There is always scope for misinterpretation.

              If my posts can be interpreted in two ways, one that makes you feel angry and one that doesn't, I meant the latter.

              Everyday is an opportunity to learn something new.
