Based on Columbia pricing of $600–$1,800 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 Columbia median.
| Scope | What it includes | Typical installed cost |
|---|---|---|
| 5 windows — retrofit | Insert into sound existing frames, vinyl | $6,200 – $8,900 |
| 10 windows — retrofit | Typical partial-home replacement | $12,400 – $16,800 |
| 15 windows — mixed | Most of a single-family home | $17,700 – $23,900 |
| 20 windows — full-frame | Whole-home, frames and trim replaced | $23,900 – $32,700 |
| 10 windows — impact / structural | Impact-rated or egress-corrected openings | $20,400 – $28,300 |
- • 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 Columbia 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.
