What shapes a Delaware project
Elevation + wind-rated assemblies on substantial improvement. Verify flood zone first.
Fewer basements; drainage and sump systems matter. Slab/crawl moisture management.
Testing common at sale. Passive mitigation cheap during construction.
Standard footings. Frost-heave on older walkways is a common finding.
Wilmington/New Castle run higher; older housing with lead-paint considerations.
Off-season scheduling at the beaches means better pricing + availability.
