Cost by project size
Generated from the same unit pricing the calculator uses.
| Project size | Estimated range |
|---|---|
| 9 window installed | $6,300 – $18,900 |
| 12 window installed | $8,400 – $25,200 |
| 15 window installed | $10,500 – $31,500 |
| 19 window installed | $13,300 – $39,900 |
| 25 window installed | $17,500 – $52,500 |
Based on Port St. Lucie pricing of $700–$2,100 per window installed.
Cost by window count and install type
Windows are priced per opening. Frame material and whether the crew does a retrofit (insert) or full-frame install drive the spread. Every row is priced against the Port St. Lucie median.
| Scope | What it includes | Typical installed cost |
|---|---|---|
| 5 windows — retrofit | Insert into sound existing frames, vinyl | $7,100 – $10,200 |
| 10 windows — retrofit | Typical partial-home replacement | $14,300 – $19,400 |
| 15 windows — mixed | Most of a single-family home | $20,400 – $27,500 |
| 20 windows — full-frame | Whole-home, frames and trim replaced | $27,500 – $37,700 |
| 10 windows — impact / structural | Impact-rated or egress-corrected openings | $23,500 – $32,600 |
- • Retrofit inserts keep the existing frame and cost less; full-frame replacement is required once the frame or sill is rotted or the opening is being resized.
- • Rough-opening changes and egress corrections turn a window job into a permitted structural job.
- • Frame material sets the floor: vinyl is the value option, fiberglass and clad-wood carry a premium, aluminum is mostly a warm-climate product.
- • In wind-borne debris regions the glazing package, not the frame, is the biggest single line item.
Basis: Each scope is priced as a multiple of the modeled Port St. Lucie median for impact window installation, so the scenarios, the size table and the calculator always agree. · Hometriva methodology

Yes. Replacing a window changes an opening protection assembly, so every Florida jurisdiction requires a permit with product approval numbers and attachment details for each unit.
Do impact windows lower insurance?
Florida requires insurers to offer wind mitigation discounts for approved opening protection. Have a wind mitigation inspection done after installation so the credit is applied.

In most jurisdictions this work is permitted and inspected. Requirements are set locally, so confirm the current application and inspection checklist with your building department before work starts.
How long does impact window installation take?
1-3 days of installation, 3-8 weeks including product lead time and permitting. Permit review and inspection scheduling are usually the largest source of variation.
