In short: a hurricane impact door is a complete door system, glass, frame and hardware, that has passed Miami-Dade's impact and pressure tests. Installed, a two-panel impact slider runs about $3,000–$6,000, a single entry door $2,500–$5,000 and a pair of French doors $5,000–$8,000, as estimates.
The opening that fails first
In a hurricane, a wide door is the weakest point in most houses. A sliding door spans several feet of glass, so the wind load on it is far higher than on a bedroom window. If it gives way, pressure builds inside and pushes up on the roof. That is why many owners start a hurricane upgrade with the patio slider and do the windows next.
Door types we put in
- Sliding glass doors. Two, three and four panels, including tall units onto pool decks and balconies.
- French doors. Hinged pairs with impact glass, set to swing in or out to suit the opening.
- Front entry doors. Solid or with a glass insert, rated together with their sidelights and transom.
- Side and garage entry doors. The walk-through doors that often get forgotten in a storm plan.

Estimates only. These ranges come from published South Florida installer pricing. A door is priced in writing after we measure the opening and check its condition.
What to check on any impact door quote
- The NOA number for the complete door unit, and that its approved size covers your opening.
- The design pressure the door is rated for, compared with what your opening requires.
- Whether the threshold and sill are rated for water, since sliders face wind-driven rain.
- Whether stucco, trim and paint around the new frame are included.
Door questions
What does an impact sliding glass door cost in Miami-Dade?
As an estimate, $3,000–$6,000 installed for a standard two-panel slider. Three- and four-panel units and tall openings run higher, and each one is priced after we measure.
Is a hurricane impact door the same as a hurricane-rated door?
People use the names loosely. What counts in Miami-Dade is that the complete unit, glass, frame and hardware together, holds a current Miami-Dade NOA for the size and design pressure of your opening.
Can a new impact door swing out?
Often, yes. Out-swing doors resist wind pressure well because the storm pushes them into the frame. Whether in-swing or out-swing suits your opening depends on the approval and the space around it.
Do I need a permit for a door replacement?
Yes. Exterior door replacement needs a permit and a final inspection in Miami-Dade, just like windows. We handle both.
