What Affects the Price
Window Size
Larger windows cost more — both for the glass and the installation. A standard 36" x 60" single hung is on the low end. A 72" x 80" sliding glass door is on the high end. Custom sizes cost 15-30% more than standard sizes.
Glass Type
Standard clear laminated glass is the baseline. Tinted glass (gray or bronze) adds $30-$60 per window for heat rejection. Low-E coatings add $40-$80 per window for energy efficiency. SolarBan glass (premium energy performance) can add $60-$120 per window.
Frame Material
Aluminum frames are standard and most affordable. Vinyl frames cost 15-25% more but offer better energy efficiency and don't conduct heat. In South Florida's climate, the energy savings from vinyl may not justify the premium for most homeowners.
Installation Method
Retrofit installation fits the new window into the existing frame opening. It's faster and cheaper but depends on the existing frame being in good condition. Full-frame (new construction) installation removes the entire existing window and frame, going down to the rough opening. It costs 30-50% more but gives a better seal and allows for size adjustments.
Structural Modifications
Older homes may need structural headers reinforced to support impact-rated products. If your home was built before the Florida Building Code (pre-2002), budget $200-$500 per opening for potential structural work.
Insurance Savings
Impact windows qualify for opening protection credits on your wind mitigation inspection. Full-house coverage (all openings protected) gets the maximum discount.
Typical annual savings: $800-$2,400 depending on your carrier, home value, and location. Over 10 years, that's $8,000-$24,000 in insurance savings — often covering a significant portion of the window investment.
Impact Windows vs Hurricane Shutters
This is the most common question we hear. The short answer: shutters are cheaper upfront, impact windows are better in almost every other way — windows protect 24/7, raise the home's value, and qualify for bigger insurance credits.

How much do impact windows cost in South Florida?
$450-$1,500 per window installed, depending on type, size, and manufacturer. A full-house installation for a typical home runs $12,000-$28,000.
Will impact windows lower my insurance?
Yes. Full impact window coverage typically saves $800-$2,400 per year on homeowners insurance through wind mitigation credits. Get a new wind mitigation inspection after installation to claim the credits.
How long do impact windows last?
Impact windows from major manufacturers (PGT, CGI) typically last 25-30+ years. The glass doesn't degrade. Frame longevity depends on material and maintenance — aluminum frames in salt air environments should be cleaned and lubricated annually.
Do impact windows block noise?
Yes. The laminated glass in impact windows provides significant sound reduction — typically reducing outside noise by 50-60% compared to standard single-pane windows.
