Generated from the same unit pricing the calculator uses.

|---|---|
| 7 window installed | $7,400 – $21,400 |
| 10 window installed | $10,500 – $30,500 |
| 12 window installed | $12,600 – $36,600 |
| 15 window installed | $15,800 – $45,800 |
| 20 window installed | $21,000 – $61,000 |
Based on San Jose pricing of $1,050–$3,050 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 San Jose median.
| Scope | What it includes | Typical installed cost |
|---|---|---|
| 5 windows — retrofit | Insert into sound existing frames, vinyl | $8,500 – $12,200 |
| 10 windows — retrofit | Typical partial-home replacement | $17,000 – $23,100 |
| 15 windows — mixed | Most of a single-family home | $24,300 – $32,800 |
| 20 windows — full-frame | Whole-home, frames and trim replaced | $32,800 – $45,000 |
| 10 windows — impact / structural | Impact-rated or egress-corrected openings | $27,900 – $38,900 |
- • 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 San Jose median for window replacement, so the scenarios, the size table and the calculator always agree. · Hometriva methodology

40% of the median — the rest is material, disposal and permit.

Frequently asked questions
Do I need a permit to replace windows in Florida?
Yes. Window replacement is a permitted alteration statewide because the opening protection and attachment must meet the wind-load requirements of the Florida Building Code. Product approval numbers are submitted with the application.
Are impact windows worth it in Florida?
Impact windows typically cost 40-70% more than standard units but can replace shutters entirely and often qualify for a wind mitigation insurance credit. In HVHZ counties, opening protection is required, so the practical choice is impact glass or approved shutters.
