Document the condition
Note where the symptom is, when it started, and how it tracks with rain or dry stretches at the Wilmington property -- that record matters more once tropical weather becomes part of the picture.
Read the local context
Wilmington's mix of historic downtown structures, postwar neighborhoods, and barrier-island homes all sit on sandy, low-lying ground with a shallow water table, regardless of which era the house belongs to.
Ask what will be hidden
Because sandy coastal soil reacts fast to both drought and heavy rain, a written Wilmington scope should spell out exactly what gets verified below grade before the job is considered finished.
Compare complete scopes
Compare Wilmington proposals on protection, access, coastal-appropriate materials, permits (historic review included, where relevant), testing, cleanup, restoration, and change-order terms -- not just the total.
What official local sources add
Two of these facts drive structural movement on the coast. The high water table means bearing conditions change seasonally rather than staying constant, and the sandy coastal soils that come with it settle and erode rather than shrinking and swelling the way Piedmont clay does — a different mechanism from most national foundation guidance. Current flood mapping matters separately: inside a mapped zone, work extensive relative to the structure's value can engage additional requirements, and in a local historic district exterior drainage work can attract review of its own.
