Openreach cable causing damage to property

AH2022

None of the builders had been into the roof area.

Good idea I will check why they haven't checked the roof.

What could the issue with the roof be and how could it impact the front wall?

The mortar has been lost by the bricks being pulled away. It is a consequence of the bricks being pulled not the other way round. Yes the bracket is holding the bricks together which leads me to believe that openreach were aware there could be a potential issue with the placement of the cable and offset the risk by installing the bracket.

No, the corner bracket is more like the type used for overhead mains electricity cables. Electricity cables are usually heavier, and the consequences of them falling are more serious.  If the bracket had been installed by the GPO/BT then the phone line would be attached to it, rather than putting it there to support the brickwork the cable is attached to.

I still don't see a mechanism where the phone line could remove so much mortar without there being considerable displacement of the bricks.

It’s not the cable causing the damage. No cable would cause the mortar to just disappear. Check your roof, the wooden panels right under the guttering seem to have a aignificant gap. Get a bricky to re-point those bricks.

That bracket looks like it supported the original telephone cables to the house in the 1950s or earlier when the connection from the pole to the house would have used 2 separate strands of wire insulated by a large air gap. This would then be jointed to a drop wire to lead into the house. Self supporting insulated drop wires were introduced in the late fifties but lots of those open wires were still in place when I joined PO Telephones in 71 as they only got replaced when they went faulty.

There is no way the current drop wire is causing that damage, but that window installation looks dodgy. Forget OR for the time being, none of their engineers are going to put a ladder anywhere near that wall, the builders will able  to do a temporary fix once they get some scaffolding in place.

@Keep_pedalling,    Thanks for that link read it with interest.

It was a bit of a eyeopener to read of the restrictions on use and discretion to be employed in good class residential districts.
It is a reminder of how class conscious and snobbish the country used to be.
Anyone writing a TI like that today would find themselves in the internets version of the stocks and possibly their employment in jeopardy.
