    Removing render on externals walls

    Hi there. A damp specialist has been to look at a house my daughter is hoping to buy. He has said then outside walls have been rendered with cement render and therefore the house cannot breathe and therefore causing damp. Also inside plasterboard has been placed over and painted in an attempt to cover it up but of course damp is still coming through.

    My question is does anyone have an idea of cost on this or not indeed they would even bother????!!!! Thank you in advance

    I never quite get this 'breathing' argument and damp 'experts' are notorious for ripping customers off.

    Where is the damp, ground floor, everywhere, only upstairs?

    Suggest you get a builder or two to come and diagnose what is going on but there and give a price. Cost also depends on area.

      Apparently the house is old and lime render should have been used. The damp appears to be on the ground floor on the walls to one side of the house only. It is definitely not rising damp.

        He is right, walls need to breathe, the cement and paint will need to come off

          What have neighbouring houses got? Have a look and talk to owners if similar

            Lime render is not cement render is it?. Good point from Artfullodger. I still say get a builder or two to have a look.

              The website linked below is informative - the cement render needs to come off and as that will likely leave a mess you probably need a breathable render back.

              You can now get renders coloured all the way through to reduce painting and insulating renders - Baumit and K-lime have been mentioned elsewhere. These will be expensive but building regs probably require you to upgrade insulation when you rerender.

              Personally I never want to buy a rendered house again. Cost obviously depends on the size of the house and the materials used - you could be looking at £10k.
