How we calculate this
We start with which window style you're replacing - double-hung, casement, sliding, or picture - since that selects which real, priced assembly (a specific combination of sash, frame, glass package, screen, and hardware) your estimate is built from. Within double-hung, the material you pick (vinyl, vinyl-clad wood, or solid wood) adjusts the price further.
How many windows you're replacing scales the per-window price into a project total. Your ZIP code then applies a real regional cost factor to material and labor rates, not a generic "low, average, or high cost area" bucket.
Our pricing is built from a licensed national costbook (unit costs for materials and labor, priced line by line) plus real regional cost indices - not a market survey, and not a substitute for a contractor’s own quote.

Cost by style
For an 8-window job at national rates, one style at a time. Computed directly from the same engine as the calculator above - enter your ZIP there for a number adjusted to your area.
| Style | Typical low | Most likely | Typical high |
|---|---|---|---|
| Sliding | $2,129 | $4,258 | $6,387 |
| Picture or fixed | $3,195 | $6,390 | $9,585 |
| Double-hung | $3,843 | $7,686 | $11,529 |
| Casement | $5,145 | $10,290 | $15,434 |
What drives the cost
Window style & material
$331–$1,885
The single biggest driver of the PER-WINDOW price - see the style comparison table above for all 4 priceable styles, and the material breakdown further up for double-hung's own 3 options. Window count (below) drives the total PROJECT cost instead, a different number this page doesn't show.
Number of windows
$1,874–$15,425
How many windows you're replacing moves the total the most - not the per-window figure above, which is count-independent by construction. This range holds double-hung fixed and spans our full window-count scale.
Full-frame vs. insert replacement
Insert replacement (reusing your existing frame) is typically less expensive than full-frame replacement (removing the frame down to the rough opening, with exterior trim and sometimes siding repair) - but this costbook doesn't have a sourced dollar figure for that difference yet. Ask your contractor to quote both if you're not sure which your windows need.
Glass package
$3,186–$5,330
Upgrading from single-glazed to insulated glass adds real, priced cost - shown here on sliding windows (the style where our data has both options at the same size) as one concrete example of the difference.
Home access & story height
Second-story or hard-to-access windows typically cost more to install (ladders, lifts, extra labor time) - this costbook doesn't have a sourced adder for that yet, so it isn't reflected in the figures above. Ask your contractor if any of your windows need special access.
Local labor rates
Enter your ZIP code above for real region-specific labor and material rates, not a generic "low, average, or high cost area" bucket.
Repair vs. replacement
Everything on this page prices a full window replacement. Repair costs depend too much on the specific problem to price generically - a small patched leak and a large storm-damaged section can both be called “a repair,” and they cost nothing alike. If your window just needs a repair, say so in the questions ahead and your matched contractor will give you a real quote after taking a look, at no cost to you.
Questions to ask a contractor
