Cost by project size
Generated from the same unit pricing the calculator uses.
| Project size | Estimated range |
|---|---|
| 9 window installed | $9,500 – $27,500 |
| 12 window installed | $12,600 – $36,600 |
| 15 window installed | $15,800 – $45,800 |
| 19 window installed | $20,000 – $58,000 |
| 25 window installed | $26,300 – $76,300 |
Based on San Francisco 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 Francisco median.
| Scope | What it includes | Typical installed cost |
|---|---|---|
| 5 windows — retrofit | Insert into sound existing frames, vinyl | $10,300 – $14,800 |
| 10 windows — retrofit | Typical partial-home replacement | $20,700 – $28,000 |
| 15 windows — mixed | Most of a single-family home | $29,500 – $39,800 |
| 20 windows — full-frame | Whole-home, frames and trim replaced | $39,800 – $54,600 |
| 10 windows — impact / structural | Impact-rated or egress-corrected openings | $33,900 – $47,200 |
- • 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 Francisco median for impact window installation, so the scenarios, the size table and the calculator always agree. · Hometriva methodology
