Groundwater seepage is excluded from standard homeowners policies. Separate flood insurance or a water backup endorsement is required.

Get bids from waterproofing specialists and a general contractor; approaches and prices differ enormously.
Ask about a transferable lifetime warranty — it holds value at resale.
Install the sump and drainage before finishing the basement, never after.
