Solid brick wall covered in render now causing damp issues
Anonymous user 05/03/2024 - 2.30 PM
Hello,
We purchased a 1710 cottage built with solid brick walls (no cavity wall). The previous owner covered the entire house in modern render. This now seems to have lead to slight damp on internal wall of the gable end (the side of house most exposed to rain). Internally the wall is covered in plaster board, some of which is now showing signs of black mold. I understand the house should be covered in a lime-based render, however I have had a few quotes through and can absolutely not afford to get that done. Is there an alternative, temporary solution that can improve the situation for the time being? E.g. installing air bricks?
Are you a tradesperson and able to answer this question?
I recommend the house should be covered in a lime-based render, and I personally would not cut corners but I understand it is expensive for it to be done but personally would not want to do a temporary solution as a temporary solution could cause more problems

I would say your next best option would be to either use pebble dash, roughcast or cladding as a cheaper alternative.
Or maybe it would be worth looking into polymer render.

Hi there. If it’s an old building it may not have damp course either. So may not be transference through the wall. It may just be absorbed from the ground. When the rain hits new render on gable the water goes into ground (probably) not rendered to footing. My advice would be to paint the render with a sealant or weather shield paint. And dig down at gable end to inspect the base of the wall. Once exposed it can dry out and be treated in a similar way or painted with a bitumen aqua seal and French drain added. Failing that you can also take off plaster and line it with a dpm and batten and new plasterboard and Replaster. Or repaint and move house if not affordable!!

With having no cavity and no insulation . I would use insulated plaster board on the internal wall on the gable to prevent cold spots

Me personally I'd fit a air brick so that there is air circulation, also I'd fit thermal plasterboards with the foam on back on to the affected walls with may help.
