Welcome to HF Diverter Company.
In 2024, Howard J. Foster, a South Florida native with years of hands-on experience in high-rise properties, noticed a recurring problem: sliding glass doors failing against Florida’s relentless storms, water intrusion, and security risks. Existing fixes were outdated, costly, or simply ineffective.
Driven by a mission to protect homes from flooding, debris, and forced entry, Howard invented the HF Diverter—a patented, dual-purpose system that combines storm-proof waterproofing with sliding door security reinforcement.
Today, HF Diverter Company is the only business in South Florida specializing exclusively in this sliding door diverter technology, serving condominiums, high-rises, and homeowners across Broward County and beyond.
