Frequently Asked Questions — Des Moines Homeowners
Des Moines sits on expansive clay soils that hold water after heavy rains. Combined with the Des Moines River's spring flood cycles and aging housing stock, hydrostatic pressure builds against basement walls — forcing water through cracks and floor joints.
Most Des Moines waterproofing projects range from $3,500 to $12,000 depending on the size of the basement and severity of the water intrusion. BAM provides free, no-obligation estimates so you know exactly what you're dealing with before spending a dollar.
Warning signs include horizontal or stair-step cracks in basement walls, doors and windows that stick, uneven floors, and visible gaps between walls and ceiling. If you see any of these in your Des Moines home, call BAM for a free assessment.
