Replacing all windows in a house typically costs between $8,000 and $45,000, with most Fort Lauderdale homeowners spending $15,000 to $30,000 for a full whole-home project. The final number depends on window count, frame material, glass rating, and whether you choose standard replacements or hurricane-grade impact windows. In coastal South Florida, code compliance shifts the math significantly, and understanding those drivers before you request quotes protects you from surprise line items on installation day.
The Real Cost to Replace All Windows in a House
For a typical single-family Fort Lauderdale home with 10 to 15 windows, whole-house replacement runs $12,000 to $35,000 installed. Standard vinyl replacements sit at the lower end. Hurricane impact windows, required across most of Broward County, push the total higher because the glass, frame, and installation all meet stricter engineering standards.
Average Cost Range Per Window
Individual window replacement costs vary widely by type. Standard single-hung vinyl windows run $450 to $900 installed. Casement and picture windows cost $600 to $1,200. Impact-rated single-hung windows range $900 to $1,800 per opening, while impact casements and specialty shapes can reach $2,500 or more. Larger openings, custom sizes, and second-story installations add labor and equipment costs to each unit.
Total Whole-House Replacement Costs
A small home with 8 windows might see totals near $8,000 for standard vinyl or $14,000 for impact-rated. A mid-size home with 15 windows commonly falls between $18,000 and $28,000 for impact installation. Larger properties with 20-plus openings, arched windows, or sliding glass doors regularly cross $40,000. Permit fees, disposal of old units, and stucco repair around openings factor into the final invoice.
Getting the total right starts with understanding how impact window pricing breaks down opening by opening, since coastal code changes the cost math entirely.
What Drives the Price in Fort Lauderdale
Four factors shape almost every window replacement quote in South Florida: impact rating, frame material, glass package, and installation complexity. Homes within the High Velocity Hurricane Zone must use products tested to Miami-Dade or Florida Building Code standards, which narrows product options and raises baseline pricing. Second-story access, tile roof clearance, and existing stucco condition also affect labor hours.
Impact Rating, Frame Material, and Installation Factors
Impact glass alone adds roughly 40% to 60% over standard glazing. Vinyl frames offer the best value and strong energy performance for most Fort Lauderdale homes. Aluminum frames handle larger spans and coastal salt exposure well but cost more. When choosing between vinyl and aluminum frames, consider your salt-air exposure, window size, and long-term maintenance preference.
Installation costs also climb when older wood-buck framing needs replacement or when stucco cutbacks are required for proper flange installation.
Standard Windows vs. Impact Windows Cost Comparison
Standard replacement windows cost less upfront but offer no hurricane protection, meaning you still need shutters or plywood every storm season. Impact windows cost 50% to 80% more per opening but eliminate shutter costs, qualify for insurance discounts averaging 10% to 45% on wind premiums, and add measurable resale value. For most Fort Lauderdale homes, the long-term math favors impact windows within seven to ten years of ownership.
Conclusion
Whole-house window replacement in Fort Lauderdale ranges $8,000 to $45,000, with impact windows commanding a premium justified by code compliance, insurance savings, and storm protection.
For homeowners weighing standard versus impact, the honest answer is that South Florida realities almost always point toward impact-rated systems that pay back over time.
