Quick answer: A single impact window installed in Tampa Bay runs about $850–$2,500, depending on its size and glass. Replacing every window in a typical home (10–20 windows) runs $12,000–$45,000. The number of openings, their sizes and the glass package move the price the most. Impact windows are made to order, so between the permit, manufacturing and installation, most projects take several weeks from signed contract to final inspection. If your home qualifies, the My Safe Florida Home program can reimburse up to $10,000 of the cost.
Impact windows are one of the bigger checks a Florida homeowner writes, so it pays to know what is inside the number before you compare quotes. This guide breaks down what you are paying for, what pushes the price up or down, the permit rules in each county, and the programs that can bring the cost down. If you already know you want impact windows, see our impact windows and doors installation service.
| Project | Typical installed range | Notes |
|---|---|---|
| One impact window | $850–$2,500 | Size and glass set the price |
| Whole home (10–20 windows) | $12,000–$45,000 | Every window replaced at once |
| Impact sliding glass door (6–9 ft) | $3,500–$8,500 | The most common door to the lanai or pool |
| Multi-panel or pocket slider | $8,000–$15,000+ | Wide openings |
| Impact French doors | $4,000–$8,000 | |
| Impact entry door | $1,500–$4,000 | Premium or decorative: $3,000–$5,500 |
What You Are Actually Paying For
An impact window quote is not just the window. A complete, permitted installation includes:
- The unit: laminated insulated glass in a PGT or CGI frame, tested for impact and wind pressure and rated for 140+ mph wind loads.
- The permit: every unit needs a Florida Product Approval, and the county or city has to approve the permit before work starts.
- Removal and disposal of the old windows.
- Installation with anchoring and sealing per the product approval.
- Opening prep and finish work: buck and stucco repair where the old window comes out, plus caulking and trim. Opening prep is one of the factors that moves the price, so ask what is included.
- Final inspection by the building department.
When two quotes are far apart, the difference is usually in this list. Ask each contractor to write down what is and is not included.
What Moves the Price
1. Number and size of openings
This is the biggest factor. A home with 12 standard windows and one slider costs far less than one with 25 openings and two large picture windows.
2. Glass options
Laminated insulated glass is the base. Low-E coatings that cut heat gain, tints and obscure glass for bathrooms all add to the price.
3. The rating each opening needs
Every opening needs a product rated for the wind pressure where it sits on the house. Corners, upper floors and homes near open water need higher ratings, and higher-rated units cost more. Coastal homes on barrier islands like Longboat Key and Siesta Key face the strictest wind-load standards in the region.
4. Opening prep
Some openings come out clean. Others need buck replacement or stucco repair before the new window can go in, and that work is part of the price.
5. All at once or in phases
You can replace windows in phases, but doing every opening at once means one permit, one mobilization and a home that is fully protected. A fully protected home is also what a wind mitigation inspection looks for when it comes to insurance discounts.
From a Recent Project
In a Tampa Bay home we replaced the original windows throughout the house, including the bedrooms, bathrooms, dining room and living room, with PGT hurricane-impact windows. We handled the project from start to finish: the permit, removal of the old windows, installation and the final inspection. In the bathrooms we used impact windows with obscure glass, so the same unit gives privacy and storm protection. You can see the full project in our 2026 hurricane season impact windows guide.
Permits, HOAs and Insurance by County
Window replacement needs a building permit everywhere we work. If your home is inside city limits (Tampa, St. Petersburg, Clearwater, Sarasota and others), the city issues the permit instead of the county.
- Hillsborough County: permits typically take 2–4 weeks. Hillsborough County permits. Homes in the City of Tampa go through Tampa Construction Services.
- Pinellas County: permits typically take 2–4 weeks. The county uses a window and door replacement form with a layout diagram of every opening. Pinellas County residential permits.
- Manatee County: permits run 3–5 weeks. HOA communities like Lakewood Ranch and Parrish often require uniform window styles, and we coordinate those approvals as part of the project. Manatee County permitting.
- Sarasota County: coastal properties face the strictest wind-load standards in our region. Sarasota County building permits.
- Insurance, in every county: the discount is documented with a wind mitigation inspection on the state form OIR-B1-1802, revised in April 2026 (Citizens notice). After installation we provide the documentation your insurer needs to apply the wind mitigation credit.
Top Tier pulls the permit, coordinates the HOA when needed and schedules the inspections.
Ways to Lower What You Pay
- My Safe Florida Home: for qualifying homes, the state reimburses $2 for every $1 you spend on the openings recommended in your inspection report, up to $10,000. The grant has to be approved before the permit is pulled, so we hold the permit application until your approval letter arrives. The program does not keep an approved-contractor list: it requires a contractor licensed for the work, which you can check at myfloridalicense.com. Top Tier is a licensed Florida General Contractor (CGC1527718). Funding depends on what the Legislature sets aside each year, so check the current status at mysafeflhome.com before you count on it.
- Insurance discounts: Florida law requires insurers to include discounts for wind mitigation features, and opening protection is one of them. How much you save depends on your carrier and your policy.
- Financing: Top Tier offers home improvement financing for qualified homeowners. Checking if you prequalify does not affect your credit score.
Impact Windows vs Shutters on Cost
Shutters cost less up front: about $1,500–$5,000 for panels, $8,000–$20,000 for accordions and $12,000–$30,000+ for roll-downs on a full home. But panels have to go up before every storm, and only impact windows protect the house 24/7 with no action from you. The full comparison is in our impact windows vs hurricane shutters guide.
How to Get a Real Number
Online calculators can only guess. An accurate price needs someone to measure every opening, check the condition of the walls and frames, and confirm what your county or city requires. When you compare quotes, ask each one to list:
- The brand and product line for each opening
- The Florida Product Approval number for each product
- Whether it includes the permit, disposal, stucco and trim
- How long the permit and the installation will take
Frequently Asked Questions
How much does one impact window cost in Florida?
About $850–$2,500 installed, depending on the size and the glass. Single-window jobs cost more per opening than whole-home projects, because the permit and the crew mobilization are spread over fewer windows.
How much does it cost to replace every window with impact windows?
For a typical Tampa Bay home with 10–20 windows, $12,000–$45,000 installed. The final number depends on how many openings you have, their sizes and the glass.
Do I need a permit to replace windows with impact windows?
Yes. Window replacement needs a permit, and the products have to match the approval on the permit. Permits typically take 2–4 weeks in Hillsborough and Pinellas and 3–5 weeks in Manatee. Homes inside city limits get the permit from the city. Top Tier pulls the permit and schedules the inspections.
How long does it take?
A whole-home installation of 12–20 windows takes 3–7 working days. Because impact windows are made to order, the whole project, from signed contract through permit, manufacturing and installation, usually takes several weeks. Custom impact doors (entry, sliders or French doors) add 6–10 weeks of manufacturing lead time.
Does My Safe Florida Home pay for impact windows?
It can, for qualifying homes and for the openings your inspection report recommends, up to $10,000. A home that already has compliant shutters cannot use the grant to switch to impact windows. See our My Safe Florida Home guide for the current rules.
Are impact windows worth the cost?
For most Florida homes, yes: they protect every opening all the time, they cut outside noise and UV, and they can lower the windstorm portion of your insurance premium. If you only need storm protection at the lowest up-front price, shutters cost less.
