How much do impact windows cost?
Impact windows cost $400 to $1,200 per window installed on HomeGuide's published figures, or $6,000 to $24,000 for an average house.
That is one of two published answers, and the honest version of this page shows you both. The same publisher prices impact windows a second way on a different guide, and the two do not line up. Knowing that is worth more than a single tidy number, because a bidder quoting either figure is quoting something real.
The two published ways of pricing the same window
| How it is priced | Published band | What it works out to |
|---|---|---|
| Per window, installed | $400 – $1,200 each | $4,800 – $14,400 for 12 windows |
| Per square foot, installed | $40 – $70 per sq ft | $280 – $490 for a 24" x 42" opening |
| Whole house | $6,000 – $24,000 | 10 to 15 windows, the publisher's average home |
| Window only, before fitting | $300 – $800 each | labour is charged on top |
HomeGuide's window replacement guide carries the per-window and whole-house figures; its hurricane shutters guide carries the per-square-foot figure and prices it against a 24-inch by 42-inch opening, which is 7 square feet. A 7-square-foot opening therefore reads $280 to $490 on one page and $400 to $1,200 on the other. We print both. Averaging two published figures produces a third number nobody published, which is how invented prices get into circulation.
Both readings against your own window count, with the permit line and the labour split: the impact window cost calculator.
What the labour costs, separately
HomeGuide puts window replacement labour at $100 to $500 per window, and prices the hurricane window unit alone at $300 to $800. Those two lines are what sits inside the installed price; they are not something to add on top of it. A quote that shows the unit and the labour separately is easier to compare against another quote than one lump figure, so it is worth asking for.

The permit, and the lines that are not on any table
HomeGuide prices permits at $50 to $200 and says most coastal states require one for this work. What no source publishes is a price for the rest of it: rotten framing behind the old window, a stucco or siding repair around the new one, a non-standard opening that has to be built up or cut down, or a second-storey unit that needs lift equipment. Those come off a site visit, which is why three written quotes on the same window count is the only reliable comparison.

There is no published price for your state
Nobody publishes a state or city multiplier for impact windows. The bands above are national. Where you live changes which product code will accept and what a crew charges, and it changes both by more than a tidy percentage would capture, so we do not apply one.
This is general information, not a quote. Prices move, codes differ by county, and only an installer who has measured your openings can price your job.
Questions people ask next
- How much do impact windows cost for a whole house?
- HomeGuide publishes $6,000 to $24,000 for an average house, and defines an average house as 10 to 15 windows. Bigger openings, sliders and doors push it above that, and the same guide's per-square-foot band is the better check on a house full of large windows.
- Why is there such a wide range?
- Opening size mostly, then the frame and the glass package. HomeGuide's own two guides price the same product differently — $400 to $1,200 per window on one, $40 to $70 per square foot on the other — which is a fair picture of how much the size of the hole in your wall drives the number.
- Are impact windows cheaper than hurricane shutters?
- No. HomeGuide prices hurricane shutters at $35 to $350 per window installed against $280 to $490 per 24-inch by 42-inch impact window, and puts a whole Florida house of shutters at $2,000 to $8,000. The windows cost more and need nothing done before a storm.
- Does the price include taking the old window out?
- In a replacement quote it normally does, and it is worth confirming in writing. Ask separately about repairs to what is found behind the old frame, because that is the line most often missing from a first quote and it is not on anybody's published table.
