A boardwalk town built on filled sand
Carolina Beach didn't become an incorporated town until 1925, well after Captain John W. Harper's steamer landing, pavilion, and 1887 boardwalk had already put Pleasure Island on the map. The island itself is a barrier strip built up largely from dredged and filled beach sand at low elevation, so the ground under the town's oldest and newest lots alike has always been more sand than bedrock.
Foundations on shifting barrier-island sand
That fill-sand base means Carolina Beach foundations deal with uneven settlement as loose sand compacts differently from one corner of a lot to the next, especially where a slab or crawlspace sits close to the water table. Pier-and-support systems that reach past the loosest surface sand tend to outperform shallow footings left to ride on fill alone.

What to describe when you reach out
Tell us the width and direction of any cracks — stair-step patterns in masonry versus straight vertical lines in drywall point to different causes — plus whether doors or windows have begun sticking, any noticeable slope underfoot, and roughly how old the structure is.
Coastal code considerations for this stretch of sand
On a barrier island like Pleasure Island, North Carolina's building code and FEMA base-flood-elevation rules both factor into how a foundation repair or pier system gets designed, since flood zone and elevation certificate requirements shift what's allowed.
