Professional Help Is Essential

• Contact city/county engineering—may have jurisdiction over drainage easements.
• Hire a local civil engineer or landscape architect specializing in residential drainage. Not all LAs do complex hydrology; ask.
• If groundwater table is high, interior French drain + sump pump may be the only fix.

Uncorrected drainage guarantees recurring mold. Act fast—health and structure are at stake.
