Columbia basement waterproofing guidance
The wet spot on the floor is rarely where the problem started -- follow the water back before deciding what to do about it.
The stormwater program is the record that reaches this work, because below-grade waterproofing is mostly an exterior drainage project. Where water is routed once it leaves a foundation is the regulated question -- discharge toward a neighboring property or into the municipal system is not simply a design choice -- and recorded drainage and utility easements frequently run exactly where an exterior curtain drain would want to go, so they are worth pulling before a scope is priced. Historic designation reaches below-grade work only where it becomes visible at grade, such as a new areaway or an exterior stair.
Think of this as an independent front door for Columbia homeowners -- not a contracting outfit, and provider openings change.
Built around local conditions
Around Columbia, the ground under the house matters as much as the house itself.
Whether a Columbia basement wall is wet from downspout runoff, poor grading, rising groundwater through sandy fill, a settlement crack, or Sandhills humidity changes what actually needs to be done about it.

Do you do the repairs?
