Impact Doors in Miami, FL
Sliding glass doors, entry doors and French doors, rated for the High Velocity Hurricane Zone and permitted with Miami-Dade.
Doors are where most Miami homes are weakest. A wall of glass onto a patio or balcony is the largest single opening in the house, it takes the most wind pressure, and on anything built before the current code it is usually the oldest thing still in place.
We install impact sliders, entry doors and French doors rated for the High Velocity Hurricane Zone, with the Miami-Dade Notice of Acceptance to match. Same crew, same permit process, same written per-opening price as the windows.
Impact sliding glass doors
The big one, and the one people most often get quoted badly. Three things drive the price:
- Width and panel count. A six-foot two-panel is a different job from a twelve-foot three-panel, and a pocketing system that disappears into the wall is different again.
- Wind pressure rating. Bigger openings need higher-rated frames, and in a high-rise or close to the water the required rating climbs.
- What is behind the frame. A slider sits in a structural opening. If the existing buck is rotten or the header needs work, that shows up as a line on the quote rather than as a surprise on install day.
| Slider | Typical range |
|---|---|
| Two-panel, 6 ft | $1,500–$3,000 |
| Two-panel, 8 ft | $3,500–$6,000 |
| Three-panel, 9–12 ft | $5,000–$9,000 |
| Multi-panel pocketing systems | from $15,000 |
Good impact sliders should still glide with one hand. If a quote is cheap and the rollers are an afterthought, you will feel it every day for a decade.
Impact entry and French doors
A front door is a small opening doing a hard job: it has to be rated, it has to lock properly, and it is the first thing anyone sees. French doors double the problem, because two leaves meeting in the middle need a multi-point lock to hold under pressure.
| Door | Typical range |
|---|---|
| Single entry door | $1,200–$2,800 |
| Entry door with sidelights | $2,500–$5,000 |
| Double entry or French doors | $4,500–$8,500 |
These prices are estimates. Every door is priced after we measure the opening, and the written quote is the number that counts.
Sidelights and transoms are glass too, so they have to be impact-rated as well. A rated door slab beside an unrated sidelight does not protect the opening, and it will not pass.
What the code actually requires
Miami-Dade and Broward are the High Velocity Hurricane Zone, which is a stricter standard than the rest of Florida. For a door that means:
- The product needs a current Miami-Dade Notice of Acceptance for the size and configuration you are installing.
- It has to be rated for both large and small missile impact.
- The anchoring has to match what the NOA specifies: the right fasteners, the right spacing, into the right substrate. This is the part inspectors fail people on.
- The work is permitted, with an inspection at the end.
We pull the permit, install to the NOA and book the inspection. Permit fees run $350–$600 for a typical project.
Doors and windows together
Most jobs are both, and doing them in one permit and one trip is cheaper than two visits. It also matters for insurance: wind mitigation credit generally depends on all openings being protected, so a house with impact windows and an unrated back slider may not qualify.
Window pricing and the full breakdown are on the cost page, and the window side of the work is on the main page.
FAQ
Impact door questions
How much does an impact sliding glass door cost in Miami?
An eight-foot two-panel slider is typically $3,500–$6,000 installed. A six-foot two-panel runs $1,500–$3,000 and a nine to twelve-foot three-panel $5,000–$9,000. Pocketing systems start around $15,000 and go up quickly with width.
Can I replace just the sliding door and leave the windows?
Yes, and plenty of people do, usually because the slider is the oldest or the most exposed opening. Just know that partial protection usually will not earn the insurance credit, which generally needs every opening rated.
Do French doors need a special lock?
They need a multi-point lock, yes. Two leaves meeting in the middle have no frame between them, so the lock is what holds the pair together under wind pressure. It is specified in the product approval, not an upgrade.
How long do doors take compared with windows?
The same, and for the same reason: the units are built to your measurements. Manufacturing is the long part. Large or custom-configuration sliders can take longer than stock-size windows.
Will a new slider still open easily?
A properly installed one will. Impact panels are heavy, so the roller and track quality is the whole difference between a door you use and a door you stop using. We will show you the roller spec on the quote.
Price the doors and the windows in one quote
One measure, one permit, one crew. Doing the whole house at once costs less than coming back, and it is what the insurance credit generally needs anyway.
