The Florida Homeowner’s Guide to Impact Doors.

What impact doors actually are (and what they aren’t).

An “impact door” in Florida is a door engineered and certified to survive two things a hurricane throws at it: a large flying object hitting the glass (the “large-missile” debris test) and the relentless push-and-pull of storm wind pressure cycling against it for hours. The glass is laminated — two panes bonded to a tough polymer interlayer — so even when it cracks, it stays in the frame and keeps the opening sealed. The frame, the hardware, the anchors, and the threshold are all part of the tested assembly, which is why a real impact door is a system, not just “thick glass.”

An impact door is not the same as a vaguely-marketed “hurricane door.” The thing that makes it real is state certification: every door Access Impact installs carries either a Florida Product Approval (FL-#####-R# format) or a Miami-Dade Notice of Acceptance (NOA) — document numbers we cite on every quote before you sign anything.

Florida building code + certifications, in plain English.

Florida splits the state into wind zones, and the zone your home sits in decides which certification a door needs. Doors are held to a high standard here because a large sliding or entry opening is one of the biggest, most pressure-loaded holes in your wall — if it fails in a storm, the pressure spike can lift a roof.

The two certification paths

• Florida Product Approval (FL-#####-R#) — the statewide certification, valid across the wind-borne-debris region: Palm Beach, Martin, Lee, Collier, Charlotte and most coastal Florida counties outside the HVHZ.
• Miami-Dade NOA (Notice of Acceptance) — the stricter county certification required in the High-Velocity Hurricane Zone (Broward + Miami-Dade). Products tested to the Miami-Dade protocols are accepted statewide; the reverse is not always true.

Design Pressure (DP) and why doors are different

Every certified door has a Design Pressure rating — the wind load it’s tested to hold. Doors generally face higher design pressures than windows because they’re larger, and wide multi-panel sliding or pocketing systems are the hardest of all to engineer. The bigger the span, the higher the DP the system has to carry, and the more the anchoring and the header detailing matter. This is exactly where a cheap quote and a correct quote diverge.

Impact door styles we install.

Florida homes use several distinct impact door styles, each suited to a different opening. We install Florida-engineered systems from CWS and ES Windows.

Most homes end up with a mix: a wide impact slider opening to the pool or lanai, an impact front entry, and French or single doors on secondary openings. The right combination is part of what we map out on the in-home consult.

Cost: what actually drives the price.

Impact door cost in Florida varies too much by configuration to quote a meaningful range online — a single French door and a 24-foot pocketing slider are both “impact doors,” and they are not remotely the same project. Rather than throw out numbers that mislead, we provide a written project quote after a free in-home consult. Here’s what moves the price up or down:

• Wind zone. HVHZ-rated products (Miami-Dade NOA) cost more than statewide Florida Product Approval products for the same opening.
• Span and configuration. A 2-panel slider, a 3-panel, and a pocketing system that disappears into the wall climb steeply in price — wider spans need higher-rated systems and more structure.
• Glass spec. Clear vs. tinted vs. low-e vs. acoustic-rated — each upgrade adds material cost.
• Frame material & finish. Aluminum frames stand up to coastal salt air for decades; color and finish options add cost.
• Structural work. Widening an opening, replacing a header, or detailing a sill pan on a second-story opening each adds labor and engineering.

Insurance savings: 15–40% wind credit, every year.

This is the part homeowners underestimate. Replacing non-rated doors with impact-rated units typically earns a wind-mitigation credit of roughly 15–40% off the wind portion of your premium — and it recurs every year you own the home. Doors matter here because the credit rewards protecting all the openings: a house with impact windows but non-rated sliding doors often doesn’t qualify for the full opening-protection credit. After every install we hand you the signed OIR-1802 wind-mitigation form your insurer needs to apply the discount.

The install process, week by week.

• Free in-home consult + measure. We measure every opening, confirm the wind zone and certification path, flag any opening that needs structural work, and quote in writing.
• Order + lead time. Impact doors are made to your exact opening, so there’s a build lead time after you approve — commonly several weeks.
• Permit + NOA paperwork. We pull the city/county permit and, in the HVHZ, submit the Miami-Dade NOA documentation. This is part of the job, not an add-on.
• Install day. Our in-house crews remove the old door, set and anchor the new system to the certified spec, detail the sill pan, and water-test sliders. Most typical openings are done in a day.
• Inspection. The building inspector signs off. We hold a thorough final inspection — because the product is certified and the install is done to spec.

How to hire an installer who passes inspection.

The product matters, but the install is where most door failures actually start. Use this checklist before you sign:

• Verify the license. Ask for the Florida contractor license number (ours is CGC1525402) and confirm it’s active.
• Make them cite the approval. Florida Product Approval or Miami-Dade NOA number for the exact product — in writing, on the quote.
• Confirm they pull the permit. An installer who skips the permit is skipping the inspection that protects you.
• Ask who does the work. In-house crews vs. day-labor subs is the difference between a sill pan detailed correctly and a callback in the first heavy rain.
• Get the OIR-1802 commitment. Confirm they’ll provide the signed wind-mitigation form so you actually capture the insurance credit.

Frequently asked questions.

Do impact doors really need a Miami-Dade NOA?

It depends on the county. Broward and Miami-Dade make up Florida’s High-Velocity Hurricane Zone (HVHZ), where doors must carry a Miami-Dade Notice of Acceptance (NOA) or a Florida Product Approval validated for the HVHZ. In Palm Beach, Lee, Collier and the rest of the wind-borne-debris region, a statewide Florida Product Approval is the standard. Either way, ask the installer to cite the approval number on the quote before you sign.

How much do impact doors lower my insurance?

Replacing non-rated doors with impact-rated units typically earns a wind-mitigation credit of roughly 15–40% on the wind portion of your premium — the same credit windows earn. Doors and windows protected together is what unlocks the full ‘opening protection’ credit. We provide the signed OIR-1802 wind-mitigation form your insurer needs after every install.

Can I replace my sliders with a wider or pocketing system?

Often, yes — but widening an opening changes the structural load path, so it may require an engineer’s sign-off and a separate structural permit. We assess the header and the opening during the free in-home consult and tell you up front whether your project is a straight swap or needs structural work.

How long does an impact door installation take?

The install itself is usually one day per typical opening once the doors arrive. The longer part is the front end: product lead time after you order (commonly several weeks) plus permitting and, in the HVHZ, the NOA paperwork. We give you a realistic week-by-week timeline at the consult.

Are impact doors better than hurricane shutters on my doors?

For most homeowners, yes. Impact doors protect the opening 24/7 with nothing to deploy, they earn the insurance credit, they cut noise, and they look like finished architecture rather than added hardware. Shutters are cheaper up front but have to be put up before every storm and don’t deliver the everyday benefits.

What lifespan should I expect?

A quality impact door installed correctly — aluminum frame, properly anchored and sill-pan detailed — lasts 20–30+ years in South Florida’s coastal salt air. The laminated impact glass carries its own manufacturer warranty; the install workmanship is where a licensed, in-house crew matters most.
