Impact Window Installation Cost South Florida 2026: Complete Breakdown
The real cost of impact windows in South Florida depends on four things: the brand you choose, where you buy the product, your county permit fees, and your contractor labor rate. Here are the real numbers — no vague ranges, no showroom padding.
Impact Window Price by Brand (2026)
All three brands carry Miami-Dade NOA certification. Price difference reflects manufacturing cost and brand positioning — not a meaningful difference in hurricane protection for most residential applications.
| Brand | Windows Stock Market | Showroom / Custom | DP Rating Range | Best For |
|---|---|---|---|---|
| PGT WinGuard Aluminum | $200–$380 | $450–$750 | DP 50–80 | Premium homes, HOA requirements, high-rise floors 4+ |
| ESW Impact Series | $170–$320 | $380–$620 | DP 40–70 | Standard residential, value-conscious homeowners |
| Mr. Glass | $110–$200 | $300–$500 | DP 30–50 | Budget replacements, rental properties, investor projects |
Prices are per-window for standard single-hung sizes (approx. 3x4 ft). Large picture windows, casements, and specialty shapes cost more. Door panels: $220–$600 depending on brand and size.
Total Project Cost by Home Size
All-in estimates: product + installation labor + permit fees + 7% Florida tax. Based on mid-range brand selection (ESW) and standard Broward County conditions.

The 4 Components of Any Impact Window Quote
1. Product cost (windows/doors)
The biggest variable. In-stock from Windows Stock Market: $110–$380/window. Custom-ordered from showrooms: $300–$750/window. Same brands, same certification, drastically different price. Doors: $220–$600 per panel.
2. Installation labor
$75–$150 per opening for standard ground-floor windows. Second floor adds $30–$80 per window for equipment. Vieser Construction includes labor in all-in project pricing.
3. Building permit fees
County fees vary. Miami-Dade: $200–$800. Broward: $150–$600. Palm Beach: $150–$500. Non-negotiable — always required. Never accept a quote that excludes the permit.
4. Incidentals
Stucco patching ($500–$1,500), debris disposal, old frame disposal. Buck frames ($35 each) if rough opening needs resizing. Mullions ($45 each) for multi-light configurations. Budget 10–15% contingency on top of base estimate.
Building Permit Fees by County
| County / Zone | Small Project | Large Project | HVHZ? | Processing Time |
|---|---|---|---|---|
| Miami-Dade | $200–$400 | $400–$800 | Yes (NOA required) | 2–4 weeks |
| Broward (coastal) | $150–$350 | $350–$600 | Yes (coastal zones) | 1–3 weeks |
| Broward (inland) | $150–$300 | $300–$500 | No (FL# accepted) | 1–3 weeks |
| Palm Beach | $150–$300 | $300–$500 | No (FL# accepted) | 1–3 weeks |
HVHZ (High-Velocity Hurricane Zone) in Miami-Dade and coastal Broward requires Miami-Dade NOA certification — Florida# product approval alone is not sufficient. Learn about HVHZ requirements
7 Factors That Change Your Final Price
Second-floor and higher requires scaffolding or lifts; more labor hours per opening
Rotted bucks, damaged stucco, or non-standard rough openings require repair before installation
Fixed picture windows are simplest; casements have more hardware and sealing complexity
After removing old frames, exterior stucco gaps must be patched and sealed
Door panels are larger, heavier, and require more labor to frame and seal properly
Contractors give better per-unit rates on larger projects due to setup efficiency
Off-season (after hurricane season) contractors compete harder for work — better negotiating position
Why In-Stock Inventory Is 30–60% Cheaper Than Custom Showroom
When a showroom sells you custom-ordered windows, you pay for: the factory manufacturing run (8–14 weeks), showroom overhead (rent, staff, displays), and the showroom margin (typically 40–60% markup over cost). The window that arrives is identical to an in-stock unit — same brand, same NOA certification, same warranty.
Windows Stock Market sources in-stock inventory from contractor overstock, builder project cancellations, and direct factory surplus. Sellers need to move product fast — you get the benefit of their urgency. Same window. Different supply chain. Dramatically different price.
Example: 12-window Broward home
Showroom custom-order (PGT)
$28,500
8–14 week lead time
Windows Stock Market in-stock (PGT)
$14,200
2–3 week installation timeline
Savings: $14,300 on the exact same PGT windows.
Return on Investment: Real Numbers
Insurance savings based on Opening Protection Category A windstorm premium reduction of 25–40%. Actual savings vary by insurer and current premium.
| Scenario | Project Cost | Annual Insurance Savings | Payback Period | 20-Year Net Profit |
|---|---|---|---|---|
| Small condo (6 windows, Mr. Glass) | $5,500 | $900/yr | 6.1 yrs | $12,500 |
| Typical home (12 windows, ESW) | $11,500 | $1,500/yr | 7.7 yrs | $18,500 |
| Large home (20 windows, PGT) | $22,000 | $2,200/yr | 10 yrs | $22,000 |
| Same large home at showroom price | $38,000 | $2,200/yr | 17.3 yrs | $6,000 |
Showroom row highlighted — same home, same windows, $16,000 more expensive at retail. 20-year profit = (annual savings x 20) minus project cost. Excludes home value appreciation.
7 Red Flags in Low Impact Window Quotes
Quote excludes building permit — illegal installation, cannot pass inspection
No mention of Miami-Dade NOA or FL# product approval number
Contractor cannot provide license number (verify at myfloridalicense.com)
Price per window below $90 — likely non-impact or uncertified glass
No written quote — verbal prices change at time of installation
Asks for more than 50% upfront — use caution, standard is 50/50
No mention of warranty — legitimate PGT/ESW/Mr. Glass products carry 10+ year frame warranties
How to Get the Best Price on Impact Windows
Frequently Asked Questions — Impact Window Installation Cost
How much do impact windows cost per window in South Florida?
Through Windows Stock Market in-stock inventory: $110–$380 per window depending on brand and size. PGT WinGuard is highest ($200–$380); Mr. Glass is lowest ($110–$200). Retail showroom custom-order pricing runs $300–$750 per window — 2–3× more for the same product. Installation labor adds $75–$150 per opening on top of the window cost.
What is the total cost to replace all impact windows in a South Florida home?
A typical 10–15 window South Florida home costs $9,500–$17,500 through Windows Stock Market (product + permit + installation, including 7% tax) vs. $18,000–$32,000 at retail showroom pricing — a savings of 30–60%. Estate homes with 25+ openings can run $27,000–$55,000 at in-stock prices.
Are building permits included in impact window installation quotes?
They should be. Vieser Construction includes all permit fees in project quotes. County permit costs: Miami-Dade $200–$800, Broward $150–$600, Palm Beach $150–$500. Always confirm permits are included in writing — some contractors quote low then add permit fees separately.
How much can I save on insurance after installing impact windows?
With Opening Protection Category A (all openings protected with impact windows), Florida homeowners typically save 25–45% on windstorm insurance premiums. On a $4,000/year South Florida home policy, that is $1,000–$1,800 in annual savings. File OIR-B1-1802 Wind Mitigation Report with your insurer after a licensed inspector certifies your windows.
Why are some impact window quotes much lower than others?
Low quotes usually mean: (1) non-impact or lower-rated glass posing as impact, (2) no building permit included — leaving you with an illegal installation, (3) unlicensed labor, (4) inferior frame quality with lower DP ratings, or (5) missing caulking/flashing that causes water intrusion. Always verify the product's Miami-Dade NOA or FL# Product Approval number and confirm permits are included before signing.
How long does it take to get an ROI on impact windows in South Florida?
At in-stock pricing with $1,500/year insurance savings: typical 8–10 year payback. At showroom pricing with same savings: 14–18 years. The in-stock price channel through Windows Stock Market cuts payback time by 4–6 years. Add resale value increase of 1–2% of home value and the economics improve further.
