Generated from the same unit pricing the calculator uses.

|---|---|
| 9 window installed | $5,900 – $17,100 |
| 12 window installed | $7,800 – $22,800 |
| 15 window installed | $9,800 – $28,500 |
| 19 window installed | $12,400 – $36,100 |
| 25 window installed | $16,300 – $47,500 |
Based on Des Moines pricing of $650–$1,900 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 Des Moines median.
| Scope | What it includes | Typical installed cost |
|---|---|---|
| 5 windows — retrofit | Insert into sound existing frames, vinyl | $6,400 – $9,200 |
| 10 windows — retrofit | Typical partial-home replacement | $12,900 – $17,500 |
| 15 windows — mixed | Most of a single-family home | $18,400 – $24,800 |
| 20 windows — full-frame | Whole-home, frames and trim replaced | $24,800 – $34,000 |
| 10 windows — impact / structural | Impact-rated or egress-corrected openings | $21,200 – $29,400 |
- • 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 Des Moines median for impact window installation, so the scenarios, the size table and the calculator always agree. · Hometriva methodology

Frequently asked questions
Do impact windows need a permit in Florida?
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.
