Generated from the same unit pricing the calculator uses.
| Project size | Estimated range |
|---|---|
| 7 window installed | $4,600 – $13,700 |
| 10 window installed | $6,500 – $19,500 |
| 12 window installed | $7,800 – $23,400 |

Based on Newark pricing of $650–$1,950 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 Newark median.
| Scope | What it includes | Typical installed cost |
|---|---|---|
| 5 windows — retrofit | Insert into sound existing frames, vinyl | $5,500 – $7,900 |
| 10 windows — retrofit | Typical partial-home replacement | $11,100 – $15,000 |
| 15 windows — mixed | Most of a single-family home | $15,800 – $21,300 |
| 20 windows — full-frame | Whole-home, frames and trim replaced | $21,300 – $29,200 |
| 10 windows — impact / structural | Impact-rated or egress-corrected openings | $18,200 – $25,300 |
- • 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 Newark median for window replacement, so the scenarios, the size table and the calculator always agree. · Hometriva methodology
