How this estimate is calculated
The estimate is built from number of windows (windows), frame material and installation type, then priced at national average rates. It reports windows, cost per window and installation, with quantities rounded up so you are never short of material and the standard waste allowance already included where it applies.

The dollar range is a national average, so treat it as a starting point rather than a bid. Labor rates, permit fees and material delivery differ by region — the state table below shows how your state compares, and construction cost by state breaks the picture down further.

Cost by frame material
Each row prices the same default job shown in the calculator above, changing only the frame material. Use it to see what the upgrade or the cheaper option really costs before you commit.
| Frame material | Low | High |
|---|---|---|
| Vinyl | $3,300 | $7,000 |
| Fiberglass | $7,000 | $14,000 |
| Wood | $6,000 | $12,000 |
| Wood-clad premium | $11,000 | $20,000 |
What the same job costs by state
Every row applies that state's construction cost index to the national range calculated above. The index bundles local labor rates, permit fees and material delivery, so it is a planning figure rather than a bid.
| State | Index | Low | High |
|---|---|---|---|
| Ohio | 0.92 | $3,036 | $6,440 |
| Texas | 0.93 | $3,069 | $6,510 |
| North Carolina | 0.94 | $3,102 | $6,580 |
| Georgia | 0.95 | $3,135 | $6,650 |
| Arizona | 1.01 | $3,333 | $7,070 |
| Florida | 1.02 | $3,366 | $7,140 |
| Pennsylvania | 1.03 | $3,399 | $7,210 |

Frequently asked questions
How much does it cost to replace one window?
A vinyl double-hung window runs about $430 to $700 installed, fiberglass $700 to $1,200, and a wood-clad premium window $1,100 to $2,000. Full-frame replacement, where the old frame is removed, adds roughly a third to the price.
Is pocket replacement cheaper than full-frame?
Yes, typically by 25% to 35% per opening. Pocket replacement slides a new unit inside the existing frame, which is fine when the frame is sound. Full-frame is required when the frame is rotten or the opening changes size.
How many windows can a crew install in a day?
A two-person crew usually completes four to six replacements in a day, or eight to ten across two days. Storms, second-storey access and custom trim slow the pace.
Do these prices include installation?
Yes. Every figure is installed, including basic interior trim and disposal of the old units. Permits, lead-safe containment in pre-1978 homes and repairs to rotten framing are quoted separately.
Does this cost change from state to state?
Yes. Applying each state's construction cost index to the national range of $3,300 to $7,000, the same job runs from about $3,036 to $6,440 in Ohio (index 0.92) to $4,686 to $9,940 in New York (index 1.42).
What is not included in this estimate?
Installed prices for standard openings, including basic interior trim and haul-away. Permits, lead-safe work on pre-1978 homes and repairs inside the opening are extra — the window replacement guide budgets them line by line. The figure is a national planning average for the work described above, not a contractor's quote.
