Not always woody, this is one I removed last week which was from a mid 70's build
litl
Over 700 ft altitude , southwest facing and blown rockwool cavity insulation which I have now sucked out.Yes lack of a tray, and was there some very severe exposure or other factor? That's certainly not typical.
Having said that, the insulation was dry and I have 7 identical catnic lintels that have been laying directly on the soil for 30 odd years with not a spot of rust to be seenOver 700 ft altitude , southwest facing and blown rockwool cavity insulation which I have now sucked out.
No tray!!

Yes that would be interesting, heres another angleAny weep holes?
Could I borrow that image, as I'd like to get some other thoughts on the failure. It must have been constantly damp, with possibly some freeze/thaw action to break the galvanising, but I would also expect there to be some sort of manufacturing defect with the coating too.

1) Contact a local qualified domestic structural engineer/surveyor who can specify the correct type of lintel to be installed and to instruct a builder based on that.
A cavity tray will be needed. Bonus points for any builder that mentions this.
For that price quoted, I'd expect the builder to be replacing a the external and internal lintel too.
