Foundation Cracks
Below the blue tape is a crack in the poured cement foundation caused by soil settlement. In most cases, this is a clear indication foundation repair is needed.
Cracks around windows and doors
The weakest part of any siding or wall is around door or window fixtures. This is why when settlement has occurred, these are the areas you will see most cracking both inside and outside.
