How Much Do Impact Doors Cost in South Florida? (2026 Guide)

Most South Florida homeowners budget carefully for impact windows, only to find out the doors are a distinct conversation, generally at the estimate, usually after the window number has been absorbed. That’s a blind spot and it makes sense. A house has a lot of windows and only a few doors, so it would seem that doors should be the smaller line item.

They're not. A single sliding glass door unit can cost more than four bedroom windows combined. The doors on a South Florida home are the apertures that determine whether the house holds together in a Category 4, and whether your insurance credit is at the top tier or the bottom one.

Below is what those numbers look like broken out by door type, what a full replacement costs by home size, and the six variables that move your final quote in either direction.

Impact Door Prices by Type in South Florida (2026)

Impact doors are not priced as a single category. A solid fiberglass entry slab and a four-panel pocketing slider are both “one door” on a quote sheet and roughly $9,000 apart. Here is what each type costs fully installed across Miami-Dade, Broward, Palm Beach, Collier, Lee, Martin, and St. Lucie counties.

Sliding glass impact doors

The most common impact door replacement in South Florida, and the one where panel count drives everything. Price scales with the number of panels and with whether the panels stack or disappear into a wall pocket.

Pocketing units carry the steepest premium because the panels slide into a cavity inside the wall, which means framing work on top of the door itself. Republic quotes sliding glass impact doors after an on-site look at the wall, never from a photo.

Swing and French impact doors

Sidelites are the glazed panels flanking the door. They add impact-rated glass area and their own framing, which is why a swing or French impact door that looks only slightly wider can price several thousand dollars higher, a single swing with sidelites often prices above a French pair without them.

Fiberglass impact entry doors

Fiberglass impact entry doors run $1,600 to $7,400 installed for a single panel. That is a wide spread, and the reason is options: fiberglass offers far more panel styles, glass inserts, woodgrain finishes, and hardware combinations than a standard aluminum French door, so two fiberglass entries at the same opening size can be thousands of dollars apart on specification alone.

Fiberglass will not rot, warp, or dent, its insulated core outperforms aluminum thermally, and it takes woodgrain and paint finishes convincingly enough to clear most architectural review boards. For a front door that is not a wide glass span, it is the better material on nearly every axis, and at the base end of the range, the better value as well.

Impact garage doors

Impact garage doors run run $2,800 to $7,500 installed for a single-car opening and $4,000 to $12,000 for a double-car opening, depending on whether the door is solid or glazed. This is the opening most South Florida homeowners defer, and deferring it is usually the most expensive decision in the project, more on why in the insurance section below.

Bifold and pivot impact doors

Bifold impact doors are quoted per panel rather than per opening, so a six-panel wall is six line items. Pivot impact doors are effectively custom in every installation, the hardware carrying an oversized panel on a central axis is the cost, not the glass.

Every range above includes the door unit, frame, hardware, installation labor, and haul-away of the old door. County permit fees, stucco and threshold finishing, and any structural repair found after removal are quoted separately, see the factors section below.

What Does a Full-Home Impact Door Replacement Cost?

Doors are rarely replaced one at a time. Most South Florida projects cover every exterior opening at once, both because the per-door cost drops when permitting and mobilization are shared across the job, and because partial protection does not earn a full insurance credit.

A standard South Florida three-bedroom lands around $8,500 for the door package. Replacing doors alongside a window project rather than as a separate job later typically saves a few hundred dollars per opening, since one permit, one mobilization, and one inspection cycle cover the whole scope.

What Affects Your Final Impact Door Price?

Two quotes for the same house can differ by thousands without either contractor doing anything wrong. Six variables account for nearly all of it.

Panel configuration and opening size

Panel count matters more than raw width. A three-panel slider and a two-panel slider in similar openings are different products with different frames, different tracks, and different design pressure engineering. Openings outside a manufacturer’s stock range move into custom fabrication, which adds 15 to 40 percent and pushes lead time out by two to four weeks. Doors reach custom sizing far more often than windows do, on multi-panel sliders, bifolds, and pivots it is effectively the default.

Glass specification

All impact doors start with laminated safety glass. From there the choices stack: 5/16, 7/16, or 9/16 inch thickness, and PVB, SGP, or VS02 interlayer. Because a door carries far more glass area than a window, each upgrade costs more per opening here than the same upgrade would elsewhere in the house.

• Low-E coating — cuts solar heat gain and UV fading, typically 10 to 15 percent on a glazed door.
• Tint — glare and privacy control, usually 3 to 5 percent.
• Obscure or frosted glass — privacy on side and service entries.
• Frame color — white and bronze price the same; black and clear anodized add roughly 10 to 14 percent.

Frame material

Aluminum carries the highest design pressure ratings and the narrowest sightlines, which is why it is standard on sliders, bifolds, and pivots, the wide glazed openings on a South Florida rear elevation routinely exceed what a vinyl frame can carry at that size. Fiberglass is the better answer for entry doors, where thermal performance and corrosion resistance matter more than maximum span. Vinyl is viable on smaller non-glazed openings outside the High-Velocity Hurricane Zone, meaning Palm Beach, Collier, Lee, Martin, and St. Lucie counties.

Hardware and locking

Multipoint locks engage the frame at several points along the door edge rather than at a single latch, which is both a security upgrade and a structural one under storm pressure. On large sliders the roller assembly is its own meaningful line item, the difference between a panel that glides for twenty years and one that binds in year three usually lives there rather than in the glass.

Threshold and existing opening condition

This is the biggest source of surprise cost on door projects, and the honest reason door quotes carry more scope risk than window quotes. A door threshold meets the finished floor at exactly the point where water has had years to find a way in. Rotted subfloor, spalling concrete at the sill, a settled or out-of-level opening, or an undersized header only becomes visible once the old unit comes out. Republic assesses threshold and sill condition during the on-site measure, but no estimator can see through a closed floor.

County permits and approval path

Every impact door installation in South Florida requires a building permit — replacing a door alters a structural opening, so there is no exemption for a like-for-like swap. Residential door permits typically run $150 to $3000 depending on jurisdiction, with Miami Beach and Coral Gables highest and Lee and Collier lowest.

Inside the High-Velocity Hurricane Zone covering Miami-Dade and Broward, every door must carry a Miami-Dade Notice of Acceptance, and the NOA number goes on the permit application. Outside the HVHZ — Palm Beach, Collier, and Lee counties — a statewide Florida Product Approval number applies instead. NOA-rated products run 10 to 20 percent higher because of the additional testing and manufacturing controls behind them. Republic includes permitting in every quote and pulls the permit under its own license.

Impact Doors vs. Standard Doors: Is the Upgrade Worth It?

If a door is being replaced anyway, the impact-rated version costs roughly $600 to $1,800 more per opening than a standard equivalent. That premium buys five things a standard door cannot deliver.

• Protection with nothing to deploy. No panels to store, carry, and bolt on while a storm is forty-eight hours out — and nothing that fails because you were out of town when the watch was issued.
• A door you can still use during a storm watch. This is the difference between doors and windows that homeowners underestimate. Panels over a rear slider seal your exit. Panels over the front entry mean going in and out through the garage for three or four days.
• A real insurance credit. Wind-mitigation discounts require permanent, always-in-place opening protection. Doors are what move the credit between tiers.
• Year-round performance. Laminated glass cuts exterior noise noticeably, blocks the UV that fades flooring and furniture, and resists forced entry — which matters on a rear slider, among the most common break-in points on a South Florida home.
• Resale positioning. In the South Florida market, documented impact protection with closed permits is something buyers and their inspectors specifically look for.

Where standard doors still make sense: interior openings, and detached structures that fall outside the wind-mitigation inspection. For anything in the building envelope, the upgrade pays back through the insurance credit and the avoided cost of a second replacement later.

How Impact Doors Affect Your Florida Insurance Discount

Florida carriers are required by law to offer wind-mitigation discounts for FBC-approved or NOA-certified opening protection. The credit applies to the windstorm portion of your premium rather than the total, and it is tiered by how complete the protection is. Doors are what move you between tiers.

A homeowner who replaces every impact window in the house and leaves the entry doors, the rear slider, and the garage door original has purchased the lowest credit tier available.

Why the garage door decides your tier

The garage door is the largest single opening on most South Florida homes and the one most likely to fail under sustained pressure. When it goes, the sudden pressurization inside the structure is what lifts roofs off walls — which is why every wind-mitigation credit schedule treats the garage door as a gate to the maximum tier rather than as one opening among many.

At $2,800 to $12,000 installed depending on whether the opening is single or double car, it is also the cheapest tier upgrade available on most projects. A homeowner phasing the work across two budget years should not leave the garage for the second year.

Claiming the discount

After installation, a licensed Florida wind-mitigation inspector completes the OIR-B1-1802 form documenting roof covering, deck attachment, roof-to-wall connections, and opening protection. One detail worth knowing beforehand: the form records the weakest protected opening on the property. A single unprotected door can hold the whole rating at a lower tier no matter how much else was upgraded. Republic supplies the product approval numbers and closed permit documentation the inspector needs.

How to Get an Accurate Impact Door Quote

A number produced from photos and a phone call is a guess. A real estimate involves someone standing at the opening. Here is what a proper South Florida door quote includes — use it as a checklist against anything you receive.

• An on-site measure of every opening. Door openings settle, and a rough opening that measured square in 1994 frequently does not now.
• A written assessment of thresholds and sills. The estimator should tell you what they found and what they cannot see yet.
• Line-item pricing per opening. Not one lump sum. You cannot compare two quotes that both just say “doors.”
• The product line named, not just the brand. “PGT” is not a specification; PGT WinGuard SGD780 is.
• The approval number. A Miami-Dade NOA inside the HVHZ, or a Florida Product Approval number outside it. A contractor who cannot produce one should not be pulling your permit.
• Permits included in the quoted price rather than added afterward.
• License and insurance up front. Republic holds Florida licenses CGC-1533058 and CCC-1337395, verifiable at myfloridalicense.com.

One more thing worth asking: what happens if something is found after the old door comes out. A contractor who has thought about that question will have an answer ready. One who has not will hand you a change order.
