I have a rotten wood lintel inside above a window, span is 1m, & the long standing leak that caused it is bring fixed.
Now I was going to replace with a concrete lintel of same size, looking at the bearing support the Lh is approx 5.5" into brickwork, but the RH side looks only to be 2" at most as its into the party wall.
What do I do?
Cheers
