Crack in Foundation
While water sealing the brick, my husband noticed a small crack where the brick meets the basement foundation. He dug it up and found that the crack goes all the way down. Inside, in the basement, there is no visible crack yet, but a level shows that the corner pillar tilts inward slightly. The house is very old and the basement is at least 70 years old, nothing has ever been level and we are not sure how serious this is or may become. We need advice on how to proceed. Thank-you in advance for any help.
