Window Replacement Costs, Broken Down by What You Choose

1. 1

   Frame material

   Angi puts aluminum at $75 to $400 a window and fiberglass at $500 to $1,500. HomeGuide's installed ranges sit higher on every material and put wood highest, at $800 to $3,800.

2. 2

   Glass package

   Angi prices single-pane glass at $200 to $500 a window and triple-pane at $1,000 to $4,000. HomeGuide says a low-E coating adds 10% to 20% to the price of the window.

3. 3

   Labor

   Angi puts labor at $100 to $300 per window and calls it the second-largest cost after the window itself. HomeGuide puts it at 25% to 35% of the total.

4. 4

   Window style

   Angi's style ranges run from $65 for a picture window to $7,100 for a bay. The style on a line item therefore prices almost nothing on its own.

5. 5

   Size

   HomeGuide attributes higher costs on larger windows to two things: more material, and units heavy enough to need at least two installers to lift.

6. 6

   Project count

   Angi says replacing all the windows at once often reduces the per-window cost. HomeGuide says the units themselves cost less when bought in bulk.

7. 7

   Removal and disposal

   Angi says most contractors include removal and cleanup, but that some charge an additional $55 to $65 per hour for disposal and the labor around it.

8. 8

   Structural work

   Angi puts repairs discovered during a replacement at $100 to $2,000 or more, and older or historic homes at $100 to $500 extra per window.

9. 9

   Region

   Angi says coastal states that require impact windows start at $1,200 to $1,500 per window for the simplest single-hung, permitting included.

The averages sit $150 apart, which looks like near-agreement until you read the ranges underneath them. Angi puts an individual window between $300 and $2,500 depending on frame material, glass type and installation complexity, while HomeGuide reports outliers all the way to $8,000. A single per-window number is the least informative thing either publisher prints, and it is the number every advertisement quotes.

Read the two tables next to each other and the difference in method is obvious. HomeGuide multiplies its per-window range straight through, so ten windows is exactly ten times one window. Angi bands instead, and its bands are not a clean multiple of any single figure — which is the volume effect HomeGuide’s arithmetic cannot show. Neither approach is wrong; they are answering with different instruments, and a homeowner who quotes only one of them will be surprised by the other.

The two agree about the floor and argue about the ceiling. Both put aluminum at the bottom. At the top, Angi has fiberglass as the most expensive material it lists and HomeGuide has wood, by a wide margin — which reflects the products each panel actually bought rather than a contradiction to resolve. Angi adds one modifier that lands on top of whichever row you are reading: expect to pay 25% to 50% more for custom finishes, oversized designs or new construction framing. Double-hung is the style most houses need most of, and the two published ranges overlap only between $350 and $650. The vinyl, fiberglass and wood pages set out what each one does in an opening, and the window types guide covers how each style operates.

HomeGuide also prices the repair alternative the sales conversation rarely raises: where only the pane is damaged, it puts window glass replacement at $300 to $650 to put a new pane in the existing frame. That is a different job from a window replacement and it belongs on the table before you agree to a whole unit. The double-pane guide covers when a sealed unit can be dealt with on its own, and energy-efficient windows explains what the ratings on the glass actually describe.

The two floors match at $100 and the ceilings do not, which is what you would expect from two panels with different proportions of straightforward and awkward openings in them. Who does the work moves the same line: HomeGuide notes that most handymen offer lower rates per window when replacing all the windows in a home at once. A quote is not comparable to another quote until you know which kind of business wrote it, and what a correct installation involves is covered on the window installation page.

HomeGuide describes the same fork without pricing it, distinguishing full-frame replacement, which includes a new frame and sashes, from pocket replacement, which fits a window inside the frame already there. It prices one neighboring job that is neither: putting a window where there was not one before costs $500 to $2,000 per window, because a new opening has to be cut and framed. If one company has quoted a retrofit and another a full-frame replacement, you are not looking at two prices for one job. You are looking at one price each for two jobs — and the condition of the opening, the age of the house and the disposal line in the grid above account for most of what is left.

HomeGuide explains the size effect as a step rather than a curve: larger windows use more material, and they may carry higher labor costs because they are heavier and require at least two installers to lift. A modest window in an awkward place can therefore outprice a large window in an easy one, which is exactly the pattern that makes two quotes for the same house look irrational until you know which openings each one walked.
