These common cracks are caused by excessive lateral earth pressure on block basements. Southeastern Wisconsin’s clay soil expands significantly when it gets wet, putting lateral pressure on the basement wall that can cause it to crack. The size of the crack is insignificant – the fact of the crack indicates the structure has failed and needs immediate attention.
All horizontal cracks are serious enough that profession evaluation is warranted. By no means do all horizontal cracks require repair, but all horizontal cracking should be monitored for any movement over time.
