Almost everyone asks the same first question: how much does one impact window cost? The honest answer is a range, because no two openings are the same.
A realistic starting range
In South Florida, many installed impact windows land roughly between $650 and $1,300 or more per window, with larger and custom units higher. These are planning numbers, not quotes. Our Miami price guide breaks this down further.
What moves the price
- Size. A small bathroom window costs far less than a big picture window.
- Style. Single-hung is usually cheapest, casement costs more. See types of impact windows.
- Frame. See aluminum vs vinyl.
- Glass package. Low-E, tint and thicker interlayers add cost. See glass options.
- Installation. Second-story access, stucco repair and old frame removal affect labor.
- Location. Miami-Dade and Broward products and permits are stricter than inland areas.
Why measuring matters
Impact windows are made to order. Size, count and conditions decide the final number, so a free on-site measurement is the only accurate way to price. We send written quotes, usually within 48 hours.
How to get a fair comparison
- Get at least two written quotes with the same list of openings.
- Confirm each includes permits, installation, disposal and the final inspection.
- Ask for product approvals for each window.

Examples of how size changes the price
Imagine three openings in the same house. A small bathroom awning window might sit at the low end of the range. A standard bedroom single-hung falls in the middle. A large picture window or a wide sliding unit lands at or above the top of the range, because it uses more glass, a heavier frame and more installation effort. A whole-house quote is the sum of dozens of these decisions.
Installation costs people forget
- Removal and disposal of old windows, especially if they are heavy or have lead paint concerns in older homes.
- Stucco and trim repair around the new frame.
- Interior finish, such as caulk and paint touch-ups.
- Permit fees and inspections.
- Special access for second-story or hard-to-reach openings.
Ask your installer to list which of these are included, so the quote you compare is complete.
Whole-house vs one window at a time
Replacing one window at a time often costs more per window because the contractor pays for mobilization, permitting and delivery each time. A single project spreads those costs. It also gives you a uniform look and a consistent wind mitigation result.
How to read a price per window
Some contractors quote per opening, others per square foot. A per-square-foot number looks lower but can climb quickly for large openings. Ask for an itemized quote and compare totals for the same list of windows.
Plan the budget
- Get a measured, itemized quote.
- Check grant eligibility.
- Price financing options.
- Ask your insurance agent what discounts you may receive.
A worked example: three-bedroom home
Suppose a typical single-story, three-bedroom home has twelve windows and one sliding door. The windows range from small bathroom units to a large living room picture window. If most windows fall near the middle of the range and a couple are large, the total can reach into five figures before the slider is added. Add the slider, and the project climbs again. This is why quotes for a whole house are so different from a single-window price.
Questions to ask your contractor about pricing
- Does this price include removal, disposal and permit fees?
- Which glass package and frame color are included?
- Are interior trim and paint touch-ups included?
- What is the deposit and what is the payment schedule?
- What is the lead time and is the price locked until installation?
When a low price is a warning
If one quote is far below the rest, ask what is missing. It may cover fewer openings, an entry-level product line, or leave out permits and finish work. Comparing the same list of openings and the same scope is the only fair way to judge.
Frequently Asked Questions
What is the average cost per impact window in South Florida?
Many installed windows fall roughly between $650 and $1,300 or more each, depending on size, style and frame. Large or custom openings cost more.
Why do two quotes differ so much?
Different product lines, glass packages, installation scope and permit handling change the total. Compare the same scope in writing.
Is the price per window or per square foot?
Some contractors quote per opening and some by size. Ask for an itemized quote so you can compare.
Does the number of windows change the price per window?
Sometimes. A larger project can spread fixed costs like permits and mobilization across more openings, but pricing varies by contractor.
Are impact doors included in a per-window price?
No. Doors and sliders are priced separately because of size and hardware.
