ash_scotland88 Posted March 21, 2021 Share Posted March 21, 2021 (edited) So moved into the new place and noticed some blown harling under neath a window (or French doors as they're almost floor to ceiling) Peeking out is some rotten metal, but I can't work out why. Only thought is a lintel below the opening, but then again why apart from distribution of load. Was this the done thing back in 1930s when the house was built?

markc Posted March 22, 2021 Share Posted March 22, 2021 1930`s would make it pre pre-fab so no idea why there would be a stranded steel cable in there, hopefully someone else may know more or seen this before Link to comment Share on other sites More sharing options...

Gone West Posted March 22, 2021 Share Posted March 22, 2021 I had a similar thing at our last house running through the mortar line which had rusted and split the pointing. It turned out to be an old earth wire but never found out why. Link to comment Share on other sites More sharing options...
tonyshouse Posted March 22, 2021 Share Posted March 22, 2021 Looks like reinforcement to me , not sure why it was there Link to comment Share on other sites More sharing options...
Triassic Posted March 22, 2021 Share Posted March 22, 2021 looks like a steel reinforced concrete cill. Nothing to worry about. treat the steel and repoint the blown area. Link to comment Share on other sites More sharing options...

Nothing to worry about. treat the steel and repoint the blown area. That could very much be it! Guessing (without googling) it's remove render (harling) to expose the length, treat the steel with some chemical coating, then patch up. Link to comment Share on other sites More sharing options...
Big Jimbo Posted March 23, 2021 Share Posted March 23, 2021 I had a bit of paint on a wall that kept bubbling up. sanded.re-painted, and back it came several times. Eventually dig it out. It was a six inch bit of bacon rind in the plaster ! 2 Link to comment Share on other sites More sharing options...
ash_scotland88 Posted May 24, 2021 Author Share Posted May 24, 2021 Slight update on this. General builder round getting some quotes and he said it's due to a lack of a sill/ inappropriate sill. He said the water runs down the cavity and gets stopped by the bricks which then causes the rust and "blow out." I get what he's saying but also all the windows are the same style of sill. And this one (and maybe another one with some blown render but could be aerial and cable clips pulled it off) have the issue. It could have been installed wrong almost 90 years a go I appreciate that. His solution is cast in place concrete sill, which I am reluctant to have as suddenly there's one window with an over hang modern style sill. Anyone else have any ideas? No sign of damp in out, no sign of rotten floor boards. Link to comment Share on other sites More sharing options...
