How Much Do Impact Windows Cost? [2026 Data]

Impact Window Cost Factors

Several factors can impact the cost of impact windows for your home, including the size of the windows, how many you have installed, and the frame material.

Prefab vs. Custom

In general, impact windows cost roughly 25% to 35% more than regular windows of comparable size and style. You can generally purchase these through specialty impact window makers in prefabricated window sizes and styles; the average prefab impact window costs $1,800.

Because impact windows are super niche, it’s harder to find them in unique window styles and sizes. If your home has window openings that don’t conform to the limited standards available through impact window dealers and manufacturers, you may need to have custom impact windows designed. Prices can reach nearly $10,000 for custom bay or bow windows built for hurricanes.

Frame Type

The window frame material for your impact windows can affect the cost. Vinyl impact windows are the most affordable, starting as low as $700 per window. Fiberglass windows are the most expensive, with prices often reaching $2,875.

Size of Windows

You can find impact windows in a number of standard sizes. In general, window prices and size increase together—the larger the window, the higher the price. For instance:

• A small (24 in. x 24 in.) casement impact window might cost $700 to $800.

• A medium-size (36x60) double-hung impact window will cost about $1,800.

• A large (12 ft.) sliding glass door could cost upwards of $8,000 to $9,000.

Number of Windows

If you’re going to install impact windows, you should ideally replace every window in your house with an impact window. A single broken window during a hurricane can destabilize the pressure in your home and cause roofs and walls to collapse. Not to mention, a broken window during a hurricane can lead to water damage and shards of glass and outside debris flying through the air.

That means you probably need to budget more than $1,800 to replace a single window; instead, you’ll need money to replace windows throughout your home.

The table below shows how the number of windows can impact the overall cost. The wide ranges allow for windows of various sizes, frame materials, and styles.

*The EPA reports that the average home has 22 windows.

Labor

When you hire a local window company to install your impact windows, you should budget $100 to $300 per window. In some cases, larger windows or harder-to-reach windows may cost more, up to $600, but contractors often offer a discount rate for large projects with multiple window installations.

Permits

In some cases, you may need a permit to replace your windows; this is up to your municipal building code. Construction permits for windows usually cost $50 per window.

Check with the city to see what permits you may need. Your contractor may take care of this work for you.

Ongoing Costs

After installing impact windows, you’ll need to budget for ongoing costs.

Regular Cleaning and Maintenance

All windows—impact or otherwise—require regular cleaning and maintenance. You can likely tackle all this work yourself; no need to hire a pro, unless you’d prefer. Here are some basic window maintenance tips to get you started.

If your windows show signs of disrepair over time, however, you’ll need to call in a local window repair pro. And because these are specialty windows, you might pay higher repair prices, for both parts and labor.

Storm Preparation

Even with impact windows, it’s a good idea to invest in hurricane shutters that you can deploy before a storm arrives. Hurricane shutters cost between $1,475 and $5,850, on average.

Beyond new shutters, you should be prepared to board up your windows ahead of Category 4 and 5 hurricanes, even if you have impact windows installed. The cost to board up windows before a hurricane is roughly $250, but if you already have the plywood on hand and don’t need to hire a handyperson near you to install it, it can cost next to nothing.

Why You Should Hire an Impact Window Pro

Hiring a local impact window installation pro costs more upfront, but you benefit from proper installation techniques, enhanced safety, and efficient weatherproofing. Pros bring the right equipment—such as specialized tools, lifting equipment, and high-quality sealants—and the experience needed to install impact windows without damaging your home’s structure or compromising its safety.

Here’s why it’s ideal to hire an impact window installation pro

• Pros know how to install impact windows efficiently while avoiding damage to the surrounding frame, siding, or trim, and ensuring the windows are securely fastened to withstand extreme weather.

• They handle the installation in accordance with local building codes and hurricane or storm protection requirements, which can be complex and vary by region. A pro ensures your windows are compliant, preventing potential legal or safety issues.

• Hiring a pro reduces the risk of improper sealing, poor alignment, or gaps that could compromise the window’s performance during a storm, leading to leaks or decreased energy efficiency.

• Many contractors can bundle services such as window removal, repairs to damaged framing, or additional weatherproofing measures, helping streamline the entire project.

3 Ways to Save Money on Impact Windows

Installing impact windows throughout a house with an average of 22 windows is expensive: $15,400 to $63,250. But there are ways to keep costs down, including:

• Replacing multiple windows at one time: If you know you eventually plan to swap out all the windows, you can save money by doing them all at once, rather than in phases. Contractors may offer you a deal for a larger project, and you’ll pay more in shipping if you order a few windows at a time.

• Choose vinyl or composite: Vinyl and composite are a more affordable window frame material option for impact windows. Choose one of these if you’re installing windows on a budget.

• Shop around: Get prices from multiple impact window companies before selecting a product. If you have only standard window sizes and shapes, you may be able to purchase all your impact windows at a local hardware store, rather than order from a premium brand and have the windows delivered. Similarly, get at least three quotes from window installers before selecting a company to handle the labor.
