South Florida Impact Doors: The Complete Homeowner Guide

South Florida impact doors must comply with the Florida Building Code's High-Velocity Hurricane Zone (HVHZ) standard — the strictest residential door code in the United States — which applies to every structure in Miami-Dade and Broward counties and requires products bearing a Miami-Dade Notice of Acceptance (NOA). org) mandates that impact-rated openings resist positive and negative wind pressures exceeding 175 mph, plus large-missile and small-missile impact testing.

A door that passes those tests does more than survive a storm — it keeps your insurance carrier satisfied, your home pressurized during a blow, and intruders out on a quiet Tuesday. Beyond hurricane protection, impact doors eliminate the seasonal ritual of bolting shutters, which can take 3 to 5 hours for an average home.

Once the door is in, your protection is permanent and code-compliant year-round. asp).

3 core frame materials dominate the South Florida impact door market: aluminum, steel, and fiberglass. Aluminum is the most popular on the coast — it resists salt-air corrosion better than steel and carries a lighter weight that reduces frame stress over time. Fiberglass offers superior thermal performance, which matters in a climate where outdoor temps hover above 85°F for 7+ months of the year.

Steel doors deliver the highest forced-entry resistance but require a quality paint system and regular maintenance to prevent rust in humid coastal air. All three materials are available with laminated insulated glass units (IGUs) featuring a polyvinyl butyral (PVB) or Sentry Glass interlayer that holds the pane together if it cracks under missile impact. Low-E glass coatings cut solar heat gain by up to 70%, reducing air-conditioning load substantially in communities from Boca Raton and Delray Beach south through Coral Gables and Coconut Grove.

Haven brings more than 30 years of South Florida construction experience to every project, and our service footprint spans all 5 counties where impact door codes are most demanding. In Miami-Dade — the epicenter of HVHZ enforcement — we work in dense urban neighborhoods like Coconut Grove, Coral Gables, and Doral as well as the barrier-island communities of Miami Beach and Key Biscayne, where salt exposure accelerates hardware and frame degradation faster than anywhere else. In Broward County we cover Fort Lauderdale, Pembroke Pines, Miramar, and the beach cities of Hollywood and Hallandale, where older housing stock from the 1970s and 1980s still runs original hollow-core doors.

Moving north into Palm Beach County, we serve Boca Raton, Delray Beach, Boynton Beach, and West Palm Beach — communities where newer HOAs often specify specific frame finishes, and our consultants coordinate with association approval processes routinely. Martin and St. Lucie counties round out our territory; Port St.

Florida law requires that any contractor pulling a building permit for structural openings hold a valid state-issued license — either a General Contractor (CGC), Building Contractor (CBC), or specialty license depending on scope. chession=&catid=&typ=). A licensed contractor does more than satisfy legal requirements — they carry workers' compensation and general liability insurance, protecting you if something goes wrong on your property.

Haven is a licensed Florida general contractor led by GC Aldo Dellamano, and every crew member working on your home is a full-time Haven employee covered under our insurance policies. We never send day labor or sub the work out to a second company. When comparing bids, confirm that every bidder is actively licensed, pulls their own permits, and provides a written warranty.
