I live in a 100+ bungalow in Kansas City. During a heavy storm recently I actually went to the basement and realized the water I see during storms is coming from the seam between floor and wall, not just from under my walk out basement door. I’ve been told by a neighbor I need tuckpointing. I don’t want to keep paying him to do repairs and want to try to do it myself. What would I need to do? My walls don’t leak but I have five spots along the wall where the water comes in.
Advice on materials and how to?
