Hi @emmab1986,

The rust coming through the render is because there is a metal bead running along that corner that has obviously gotten wet and, over time, has rusted. There are plastic beads, that can be used instead which would not be susceptible to rust.

The trade you would need to speak to is a renderer. They will be able to scrape back the existing render, remove and replace the bead and then redo the render.

Let me know if you have any further questions.

Hi @emmab1986,

I just thought I'd add a few resources for you if you'd like to give the repair a try yourself.

• How to repair a rendered wall
  
  
• How To Render
  
  
• How To Render Corners.

These articles should help you understand what is involved.

Hi @emmab1986,

Looking at the other windows I am pretty sure that one has water ingress and likely from above.

Can we please have some photos looking up the wall.

Cheers

I'll take some more photos
