Impact Window Replacement: The Whole-Home Upgrade, Done Right
Replacing every window in a Florida home is the single most consequential hardening project most families ever undertake: it changes the hurricane math, the insurance bill, the electric bill, the noise level, and the resale story all at once. It is also a construction project with real sequencing, permits, product lead times, installation logistics, inspection, and doing it right is the difference between a fortress and an expensive disappointment. Here is how Florida Impact Shield runs whole-home replacement, and what it costs in 2026.
Impact Window Replacement by Florida Impact Shield: Licensed CBC contractor, end-to-end service, measure, product, permits, installation, inspection, cleanup, with insurance savings and My Safe Florida Home grant funding built into the plan.
How the Project Actually Runs
Step one is the free in-home assessment: a licensed estimator measures every opening, evaluates frame conditions, and prices the project exactly, including your projected insurance savings and grant eligibility. On approval we order product (the lead-time phase, typically four to ten weeks by manufacturer and season) and pull permits. Installation itself moves fast: an experienced crew completes most single-family homes in one to three days, opening by opening, weather-sealed the same day, your home never left exposed overnight. Final inspection closes the permit, and your wind mitigation inspection documents the upgrade for insurance credits.
Retrofit vs New-Frame: The Real Decision
Every replacement quote answers one technical question per opening: keep the existing frame or tear out to the rough opening? Retrofit installs are faster, cleaner and cheaper where existing frames are sound; new-frame (full tear-out) is the gold standard where frames are corroded, water-damaged or out of square, and for buyers wanting maximum performance and warranty position. Most homes end up mixed, and honest per-opening recommendations, not one-size answers, are where an experienced contractor earns trust.
2026 Replacement Costs
| Project Scope | Typical Installed Range |
|---|---|
| Per window (standard sizes) | $700 - $1,600 |
| Typical 10-15 window home | $10,000 - $25,000 |
| Larger homes with doors and sliders | $25,000 - $60,000+ |
Our full cost guide and per-window breakdown detail the variables; 0% financing spreads the investment, and the offsets below shrink it.
The Offsets: Insurance and Grant Money
Whole-home replacement is exactly what the savings machinery was built for: complete opening protection unlocks wind mitigation credits of up to 35% on the windstorm portion of your premium, year after year, and the My Safe Florida Home grant matches $2 for every $1 you spend up to $10,000 for qualifying homeowners. Between grant dollars, premium savings, energy reduction and resale value, replacement is the rare renovation with a genuine payback schedule.

Frequently Asked Questions
How long does whole-home impact window replacement take?
Most single-family replacements complete in one to three days of on-site installation once product arrives, with the full project timeline, measure, permit, manufacture, install, inspection, typically running six to twelve weeks depending on product lead times and your building department.
What is the difference between retrofit and new-frame replacement?
Retrofit (flange-over or insert) installs the new window into or over the existing frame, faster and less invasive; new-frame (full tear-out) removes everything to the rough opening, the gold standard for compromised frames and maximum performance. Our estimators recommend per opening based on frame condition.
Can I replace windows in phases?
Yes, many families phase by elevation or floor, but note that full insurance credits require every opening protected, so the biggest savings unlock when the final opening is done. Grant rules and phasing strategy are worth planning up front, which our estimators map for you.
Do I need permits for window replacement in Florida?
Yes, window replacement requires permits and inspections throughout Florida, and unpermitted work creates insurance, resale and legal problems. Florida Impact Shield handles permitting and inspections end to end on every project.
