In removing the render above a window I'm about to replace, I've revealed an absence of any lintel on the outer skin of bricks (there's a softwood lintel on the inner skin).
I'm planning to install a simple L-shaped steel lintel above the 1800mm opening, on which I thought I'd run a course of soldier bricks.
Should I use shore-props (acrows) and if so, what's the procedure for removing the old window / shoring the opening / installing the lintel?
I just can't figure how to time slotting in the acrows and oiking out the old window without getting a whole lot of bricks on my head.
