Impact Windows Cost in Florida: Replacement Prices, Insurance Savings and Resale Value

Impact windows cost Florida homeowners more than standard windows, but many owners see them as money well spent. They protect the home in a storm, they can lower the wind part of an insurance premium, and buyers often ask about them first. This guide covers what impact windows cost per opening, what drives the price, how permits and product approvals work, how wind mitigation credits are earned and what new windows mean when you sell a home in Palm Beach County.

Key takeaways

• Angi's 2026 data puts professional impact window installation at about $700 to $2,875 per window, depending on size and frame. Large sliding glass doors can cost far more.
• Florida law requires insurers to include credits or discounts for wind mitigation features, including opening protection, in their rate filings.
• A wind mitigation inspection on the state's form (OIR-B1-1802) is valid for up to five years if the home has no material changes.
• The My Safe Florida Home program has offered grants of up to $10,000 for items such as impact windows and doors, subject to its rules and funding.
• Impact windows can help a home sell, but they rarely return their full cost in price alone. The insurance savings and buyer appeal are part of the payoff.

What impact windows cost in Florida per opening

Most quotes are priced per opening, which means each window or door. According to Angi, professional impact window installation runs about $700 to $2,875 per window in 2026. The low end tends to be smaller vinyl windows. The high end tends to be larger windows with fiberglass frames.

Size changes the number a lot. For example, Angi estimates a small 24-by-24-inch casement impact window at $700 to $800. A medium 36-by-60-inch double-hung window runs about $1,800. And a large 12-foot sliding glass door can run $8,000 to $9,000.

Angi's figures are national, not specific to Florida. Still, they give you a fair range to test quotes against. A whole-house job adds up fast, since most homes have many openings. So count every window and door before you set a budget.

Labor's share of impact windows cost in Florida

Angi puts labor at about $100 to $300 per window, with larger or harder-to-reach windows costing up to $600. Older homes can add more work. For instance, block walls may need repair, or old frames may come out in pieces. Ask each installer what the quote includes, such as stucco patching, painting and disposal.

What drives impact windows cost in Florida

Two quotes for the same house can be far apart. Here are the main reasons why.

• Frame material. Vinyl is usually the least costly, then composite, aluminum and fiberglass, per Angi's ranges.
• Window style. Fixed windows cost less than ones that open. Sliding doors and French doors cost the most.
• Glass package. Tinted, low-E or noise-reducing glass adds cost.
• Design pressure. Homes closer to the coast or higher up may need products rated for stronger wind loads.
• Custom sizes. Odd shapes, arches and very large openings take custom work.

Product approval

Impact windows sold in Florida should carry a Florida Product Approval number or a Miami-Dade Notice of Acceptance. Those approvals show the product passed testing for wind and impact. Your installer should list the approval number on the quote and on the permit. Keep a copy for your records and for future buyers.

Permits and how they add to impact windows cost in Florida

Replacing windows generally needs a building permit from your city or from Palm Beach County, depending on where you live. The permit leads to an inspection, which confirms the windows were installed to code. Most installers pull the permit for you, and the fee is often built into the quote. Ask to be sure.

Palm Beach County is not in the High-Velocity Hurricane Zone, which covers Miami-Dade and Broward. Even so, the county is in a wind-borne debris region under the Florida Building Code, so opening protection rules still apply. Your installer should know the local rules.

Closing out the permit matters when you sell. An open or expired permit can show up in a buyer's title search. That can slow a closing or lead to a request for a credit. So make sure the final inspection passes and the permit is closed.

Wind mitigation credits and insurance savings

Florida's insurance law encourages owners to harden their homes. Under section 627.0629 of the Florida Statutes, insurers must include credits, discounts or other rate differences for wind mitigation features in their rate filings. Opening protection is one of those features, along with roof shape, roof-to-wall connections and others.

Since October 1, 2023, insurers must also explain the mitigation discounts they offer on their websites. So check your insurer's site to see how opening protection affects your rate.

The wind mitigation inspection

To get credit, your insurer will want proof. That usually means a wind mitigation inspection on the state's Uniform Mitigation Verification Inspection Form, OIR-B1-1802. The Office of Insurance Regulation updated the form effective April 1, 2026. Only inspectors authorized under section 627.711(2)(a) can complete it.

According to the Office of Insurance Regulation, the form is valid for up to five years if no material changes are made and no errors are found. New impact windows count as a change. So after your install passes final inspection, get a new wind mitigation report and send it to your insurer.

How much you save depends on your home, your insurer and your other features. The state's OIR-B1-1699 form shows the range of wind premium credits for existing single-family homes. Our guide to Florida hurricane insurance explains how deductibles and wind coverage work.

Grants that can lower impact windows cost in Florida

The My Safe Florida Home program has offered grants of up to $10,000 for hurricane hardening. Impact windows and doors are on its list of eligible upgrades, along with roof and garage door work. The program's eligibility, matching rules and funding have changed between cycles. In addition, money can run out. So check the program's site for current rules before you sign a contract, since some steps must happen in a set order.

How impact windows affect resale value

Buyers in South Florida care about storm protection. As a result, impact windows often show up near the top of a listing. They can help a home stand out, and they spare the buyer the cost and hassle of shutters.

However, new windows rarely add their full cost to the sale price. An appraiser will look at what similar homes with and without impact windows sold for. In many neighborhoods, buyers expect some form of opening protection, so missing it may hurt more than having it helps.

The insurance angle matters too. Many buyers get insurance quotes during the inspection period. A home with a current wind mitigation report showing opening protection may get a better quote. That can make your home easier to buy, especially for a buyer with a tight monthly budget.

Should you install impact windows before selling?

It depends on your timeline and your market. If you plan to sell within a year, a full install may not pay off in price alone. Still, it may help if most nearby homes already have them. On the other hand, if you will stay a few years, you get the insurance savings and storm protection while you live there.

In August 2026, Palm Beach County single-family homes had a median price of $650,000 and took a median 40 days to go under contract, according to Miami Realtors. In a market where buyers have choices, features that lower their costs can help. Ask your agent how homes with and without impact windows have sold near you, whether you live in Jupiter, Boca Raton or Port St. Lucie.

Impact windows cost in Florida vs. shutters

Shutters are the other common form of opening protection. Accordion, roll-down and panel shutters can also count toward wind mitigation credit if they meet the rules. They usually cost less up front.

The trade-off is effort. Panel shutters must be put up before each storm, and some owners can't do that alone. Impact windows protect the home all year with no setup. They can also cut noise and help with energy use, depending on the glass. If you are weighing new openings, our guide to what it costs to add a window covers the framing side.
