Replacing the windows in a Florida home runs $4,500 to $30,000 in 2026, with a typical 12-window single-family home landing around $12,000–$16,000 for vinyl-frame impact-laminated units. The range is wide because three things move the bill independently: window count, frame material, and whether the glass needs to be impact-rated for hurricane code.
This guide breaks down how Florida window pricing actually works, why HVHZ (the High-Velocity Hurricane Zone) changes the math, and what to expect at each step. The calculator below uses the same coefficients we've verified against contractor quotes across Tampa, Orlando, Miami, Jacksonville, and Fort Lauderdale.
What you'll actually pay
For a typical 1,800-sqft Florida home with 12 standard 3×5 single-hung windows (the most common spec), here's the realistic 2026 installed range by configuration:
- Vinyl + double-pane Low-E (non-HVHZ baseline): $700/window typical, $8,400 whole-house — the budget-tier complete-replacement spec, common inland.
- Vinyl + impact-laminated (FL-recommended): $1,100/window typical, $13,200 whole-house — the most common FL spec. Insurance discounts often offset 4–8% of the premium.
- Aluminum + impact-laminated (coastal): $1,400/window typical, $16,800 whole-house — preferred within 1 mile of saltwater for corrosion resistance. See the vinyl vs aluminum windows for Florida write-up for the salt-air corrosion-life vs cost trade.
- Fiberglass + impact-laminated: $1,500/window typical, $18,000 whole-house — quieter, more thermally stable than vinyl, but slow-growing market in FL.
- Wood-clad + impact-laminated: $1,800–$2,200/window typical, $21,600–$26,400 whole-house — premium-segment, design-driven choice.
In Miami-Dade or Broward (HVHZ), add ~18% across the board for Notice of Acceptance products and stricter fastening. The numbers above assume non-HVHZ counties.
These figures include removal of the existing frames, installation labor, basic flashing and sealing, and the new units themselves. They exclude: permits ($75–$250 per window in some counties), stucco repair ($150–$400/window if the old frames had stucco wrap), and interior trim work if the rough opening changes.
Why Florida is different
A window anywhere has to keep weather out. A Florida window has to do that and withstand wind-borne debris during a hurricane — without lifting off its mounting. The state's building code reflects that, and so does the cost.
Two FL-specific factors drive the price meaningfully:
1. HVHZ vs non-HVHZ. If you live in Miami-Dade or Broward, your windows must comply with HVHZ (High-Velocity Hurricane Zone) requirements — meaning Miami-Dade NOA (Notice of Acceptance) products, enhanced fasteners, and field-witnessed installation. Outside HVHZ but still in coastal counties, you need Florida Product Approval (FPA) but not NOA. The premium for HVHZ is about 18% over equivalent non-HVHZ products because of the stricter testing, smaller product pool, and more involved permit process.
2. Impact-laminated glass vs hurricane shutters. Pre-2010 FL homes often have shutters bolted next to single-pane windows. The modern alternative is impact-laminated glass — two glass panes bonded around a clear vinyl interlayer, which holds together when hit. Impact windows cost more upfront ($220–$480/window over standard double-pane) but eliminate the shutter labor every storm and typically qualify for a wind mitigation insurance discount of 15–35% off the wind portion of your premium. The impact windows vs hurricane shutters head-to-head runs the cost-vs-convenience math; the are impact windows worth it for Florida homeowners guide handles the insurance-discount payback calc.
HVHZ math: what makes Miami-Dade and Broward cost more
The 18% HVHZ premium is real but it isn't arbitrary. It's the sum of four specific cost drivers that don't apply in the rest of FL.
Miami-Dade NOA review — every product on an HVHZ install must carry a current Miami-Dade Notice of Acceptance, not just statewide Florida Product Approval. The NOA product pool is narrower (a few hundred window NOAs vs. thousands of FPA-approved), pricing tier-set higher by manufacturers, and NOA expiration dates force product refreshes more often. The NOA is verified at permit intake and again at field inspection — typical NOA review adds 5–9 business days to permit timeline.
Engineer-stamped drawings — HVHZ permits require sealed installation drawings showing fastener pattern, embedment depth, and continuous load path back to structure. Engineer review typically runs $400–$900 per project (one drawing set covers all openings on the same wall type). Non-HVHZ projects don't need engineer drawings at all.
Fastener pattern — HVHZ specifies typically 6 fasteners per jamb side (1/4-inch Tapcons or equivalent into structural framing) versus 4 per side in non-HVHZ. Material cost is small but labor adds 15–25 minutes per window for the extra anchor verification.
Missile-impact testing per FBC Section 1626 — HVHZ-approved products must survive a 9-lb 2x4 launched at 50 ft/s plus 9,000 cyclic pressure cycles before approval. The testing alone adds $40–$110 per window to the manufacturer's tier-set price; the engineering result is the impact-laminated glass and reinforced frame you see on every HVHZ unit.
The combined effect: an HVHZ permit + product + install runs ~18% over the same scope in a non-HVHZ FL county. The premium is unavoidable for Miami-Dade and Broward addresses — but homeowners in those counties also see the largest wind-mit insurance discounts (often 30–40% off the wind portion), which partly offsets the higher upfront cost over a 5–8 year horizon.
Cost by Florida metro
City-level cost variance for a typical 12-window whole-house vinyl impact-laminated project (the most common FL spec) breaks down roughly as follows:
| Metro | County | HVHZ | Typical 12-window | Per-window typical |
|---|---|---|---|---|
| Miami | Miami-Dade | Yes | $15,500–$22,000 | $1,300–$1,830 |
| Fort Lauderdale | Broward | Yes | $15,000–$21,000 | $1,250–$1,750 |
| Tampa | Hillsborough | No | $11,500–$16,000 | $960–$1,330 |
| Orlando | Orange | No | $11,000–$15,500 | $920–$1,290 |
| Jacksonville | Duval | No | $10,500–$15,000 | $875–$1,250 |
| Naples | Collier | No | $12,500–$17,000 | $1,040–$1,420 |
| Sarasota | Sarasota | No | $11,000–$15,500 | $920–$1,290 |
Coastal exposure within a metro adds 5–10% (Marco Island in Collier, Anna Maria Island in Manatee, the barrier-island ZIPs in Pinellas) because of corrosion-rated component requirements on hinges, locks, and exterior trim. Inland subdivisions within HVHZ counties still pay the full HVHZ premium even if they sit 25 miles from the coast — the regulatory line is the county boundary, not distance to saltwater.
The window count trap
Most homeowners underestimate their window count by 20–30%. A "typical" FL single-family home has more windows than people remember:
- Small home (1,200 sqft): 8–12 windows
- Mid-sized (1,500–2,000 sqft): 12–18 windows
- Large (2,500+ sqft): 18–28 windows
- Lanai or screen-enclosed pool deck: add 4–8 large units for sliding doors or transoms
Walk the perimeter and count before you call for quotes. Contractors will count for you, but a wrong count up front leads to mismatched quotes and surprise upgrades during installation.
Florida frame brands worth knowing
Five impact-window brands matter in Florida for whole-house replacement projects, and the brand you specify drives both upfront cost and downstream warranty experience:
- PGT WinGuard (manufactured in North Venice, FL) — the FL-default vinyl-impact. $950–$1,650/window installed depending on size and HVHZ status. Broadest dealer network in the state, shortest lead times on stock sizes, and the deepest catalog of HVHZ NOAs if you decide to upgrade later. PGT is the safe default for most whole-house projects outside direct beachfront.
- CGI Sentinel — premium aluminum-impact, manufactured in Miami. $1,200–$2,100/window installed. Marine-grade hardware, thermal-broken aluminum frame; the right call within 1,000 ft of saltwater where vinyl frame degradation accelerates from salt-air exposure.
- ES Windows / Eastern Architectural — Miami-based US operation of Tecnoglass, manufactured in Barranquilla, Colombia. $1,400–$2,500/window. Custom-shape NOA depth, mid-luxury architectural builds, common in Miami-Dade and Broward custom homes and large-opening modernist designs.
- Custom Window Systems (CWS) — value-tier HVHZ, manufactured in Ocala, FL. $850–$1,400/window. 10–25% installed-cost savings over PGT for standard residential openings with adequate HVHZ certification on common stock sizes.
- Eco Window Systems — energy-efficiency leader in mid-tier vinyl-impact, manufactured in Medley, FL. $1,000–$1,650/window. Lowest U-factor in the FL vinyl-impact category; growing dealer footprint in Miami-Dade and Broward where reducing summer cooling load matters most.
Mid-tier vinyl-impact (PGT, CWS, Eco) covers the majority of FL whole-house projects. Premium aluminum (CGI, ES) makes sense on direct-coastal or architectural builds. Install quality matters more than brand tier in most real-world outcomes — most FL window failures trace to improperly flashed rough openings and fastener-spec violations, not to the window itself. The Florida impact window brands explained guide walks through each brand's NOA depth, warranty terms, transferability, and authorized-dealer network in detail.
Insurance angle worth getting right
Florida homeowners' insurance carriers credit wind-mitigation upgrades — impact windows are the biggest single credit available, typically 15–35% off the wind premium of your policy when all glazed openings qualify. To get the credit you need:
- A wind-mitigation inspection form (OIR-B1-1802) completed within 5 years
- Impact-rated products documented at Opening Protection class A or B on the form (A = all glazed openings impact-rated; B = impact-rated all glazed plus shutters on others)
- Permitted installation (carrier may reject the credit if no permit was pulled)
Don't leave the credit on the table. Ask your contractor for the model numbers and FL product approval numbers up front so the wind-mit inspector can document them correctly.

The numbers below adjust for window count, frame, glass, removal, and HVHZ status — and apply Florida labor rates. For city-specific multipliers (Miami-Dade runs ~10% above FL baseline before HVHZ premium; Jacksonville ~5% below), see the city pages linked below.
Hurricane-prep window projects pair naturally with roof replacement (Opening Protection plus roof tie-down both feed the OIR-B1-1802 wind-mit credit) and attic insulation (full thermal envelope upgrade in a single permit cycle).
