Hi, I've been a visitor to this site for a few years, it's the best. I'm in the process of doing some renovation work on an ex 1950's ish council house I bought recently. It's previously had various work done (some good and some bad). The picture shows a window that's been fitted in place of the back door when the house was extended (more on the extension another time). The window is obviously wider than the original door and there is nothing supporting the lintel on one side. I'd be interested in some opinions, should I replace the lintel or could I put another lintel under the original. It's a semi and the the window position is in the middle of the gable end.
