I have owned a brick bungalow since 1975, it was built in the 1920's. We have never had any settling problem since we've owned it, but the last couple of years I have noticed that there is a diagonal split in the bricks, and that one of the windows does not close correctly. The only thing that I can think of, that may be causing this is, my neighbors gutter overflows when it rains, and saturates the ground, and there may be some erosion going on. Any suggestions as to what I can do, or what the cause may be.
