Flood Flaps

What Flood Flaps does

Flood Flaps, LLC is a privately-held, founder-owned manufacturer of engineered flood vents headquartered in Isle of Palms, South Carolina, founded in 2012. The company designs and produces three core product series—Multi-Purpose Series (allows air circulation), Sealed Series (prevents air circulation for conditioned enclosures), and Overhead Garage Door Flood Vents—each built around a patented rubber flap and grill system housed in UV-enhanced ABS plastic. The vents remain closed under normal conditions and open automatically under hydrostatic pressure from rising floodwaters, delivering FEMA/NFIP-compliant flood relief while each unit covers 220 square feet of enclosed area. The company holds ICC-ES Evaluation Report ESR-3560 and Florida Product Approval #17381 (including HVHZ clearance), positioning its products as code-compliant across all 50 U.S. states and specifically within Florida's most stringent high-velocity hurricane zones.

The business model is straightforward one-time hardware sales at MSRPs ranging from $115 to $165 per vent, distributed through an authorized dealer network of building supply retailers, lumber yards, and hardware stores across approximately a dozen coastal U.S. states (SC, NC, NJ, DE, FL, TX, VA, NY, MS). Distribution is supplemented by two independent regional sales representatives covering Florida and New Jersey, while demand generation is driven by trade show participation (SEBC, TFMA, ASFPM, JLC Live) and content marketing on flood insurance and building codes. Customer segments are primarily SMB- and consumer-oriented: residential homeowners in Special Flood Hazard Areas seeking insurance premium reductions, residential contractors and builders, and a secondary commercial property owner segment. The firm operates with 1–10 employees, has never raised outside funding, and reports no disclosed revenue, consistent with a small, founder-run specialty manufacturer serving a regulated niche of the U.S. construction market.
