Blown render on back of house

[GG1977]

Hi, I have blown render mainly around the back PVC door and its making the internal wall damp. How can i repair this in these conditions as I think I can't do any repair render work whilst it is so wet, but I need to stop the water coming in. Is there a temporary fix I can do?

The render is still on the wall but with holes and it's very loose, but i don't want to expose the brickwork anymore without having a plan in place.

why not post photos of the blown render and the interior water damage?

thanks for the pics. but it would help further if you stood back, and showed the whole frame from the outside, and inside the kitchen?

can you remove the appliance or cabinet thats just inside the kitchen - it might be obscuring hidden damage?


you will have to hack off all water damaged or stained plaster inside the kitchen - and remove the metal corner bead (its rusting) - maybe remove all the way up to the ceiling or perhaps only past where its moisture affected? and replace it with a plastic corner bead.

can you remove the grey brick step and then hack off all render below the Pvc sill and around the sill and up the reveal, removing all cracked, damaged or stained render back to masonry?
all bubbly render is water damaged.

outside render must finish just above any existing DPC - render cannot be in ground contact or allowed to bridge the DPC.

any cracks like the cracks high up near CI pipes must be raked out and sealed.
