How Much Do Soundproof Windows Cost? [2026 Data]

Soundproof windows cost $900 per window on average, though factors like size, material, and the number of windows you need influence the final price. You can expect to pay between $100 and $1,500 for soundproof windows. Few things are more frustrating than the blaring sound of a car, plane, or your local garage band interrupting your peace and quiet. The good news is that you can cut down that noise pollution by installing soundproof windows.

Soundproof Windows Cost Breakdown

You can expect to pay $300 to $1,500 to soundproof one window, with an average cost of $900 per window. The total project cost depends on factors such as the method you use to soundproof your windows and if you’re DIYing this project.

Number of Windows

The number of windows you want to soundproof will determine your final project cost. For example, if you need to soundproof five windows in your home, you could expect to pay around $4,500, including installation.

Size

Soundproofing costs also vary based on the size of your window, ranging from $100 to $1,200. Of course, the larger your window size, the more material you’ll need to soundproof it. Also, if you plan on installing a larger window type, you’ll also need to pull a permit. 

Method

There are different ways to soundproof windows. Let’s dive into each one below.

Double-Pane Windows

The average cost for a double-pane window is $350 to $850. As the name would suggest, double-pane windows have two glass panes, typically with argon, nitrogen, or krypton gas between the panes. While not drastic, there is a noticeable difference in noise reduction when it comes to double-pane versus single-pane windows. 

Triple-Pane Windows

On average, triple-pane windows cost $400 to $3,540 per window to install. They have three glass panes with spacer gases between each and provide more noise reduction than double-pane windows.

Window-Inserts

When a full window replacement isn’t optimal, you may lean toward window inserts, which have an average cost of $250 to $500 per window and help with soundproofing. Window inserts are when new windows are installed on the interior side of your window in the existing frame, helping to filter more noise.

Laminated Windows

Laminated windows cost $10 to $20 per square foot per window and consist of two sheets of glass with an interlayer of plastic. They can reduce noise pollution by 75%.

Labor

Depending on your location, the actual labor cost you’ll be quoted may be outside of the national average, but most homeowners spend $100 to $800 per window on labor costs. However, upper-level soundproofing windows will have more expensive labor fees than ground-level windows since window professionals may need to use a ladder or access the roof to work on higher floors.

Frame Material

The frame material you’ll need to soundproof your window will also determine how much you can expect to pay for the total project. For instance, the cost of wood window frames is almost twice as much as installing soundproof windows with aluminum or vinyl frames. Depending on which material you choose, you’re looking at $150 to $2,740 in material costs, with vinyl being the most expensive option.

As an added bonus, repairing or replacing your old frames can make your windows more energy efficient, so keep that in mind when selecting your new frame type.

Permits

While not everybody will need to get a permit to soundproof windows, those who are altering the structure of their home will. The cost of a window permit is $50 to $200 per window but can vary widely depending on your local regulations.

Why You Should Hire a Soundproofing Pro

Installing double- and triple-pane windows requires time, experience, and skills to ensure there aren’t any gaps or openings that can allow air to seep through and decrease its effectiveness. So, this is a job best left to your local soundproofing pros.

Here’s why it’s ideal to hire a soundproofing pro

Installing soundproof windows is an extensive project that requires expertise. Here are some of the top reasons to work with a pro:

• Soundproofing pros ensure windows, frames, and walls aren’t damaged in the installation process.

• They have the tools and materials needed to install soundproofing windows safely and effectively.

• Working with a pro ensures your project is done accurately and without the need for costly repairs down the line.

• Bundling soundproof windows with other services, such as weatherproofing or tinting, can save on overall costs.

Alternatives to Soundproof Windows

If installing new, soundproof windows isn’t a project you’re ready to take on just yet, consider some other options. 

Foam Plugs

While not always pretty to look at, foam plugs are efficient and cost $25 to $75 per window. You can insert them into your window’s frame to create an airtight finish that helps block out noise.

Acoustic Caulk

Acoustic caulk, which costs $15 to $100, is a flexible caulk that works as a sound inhibitor. Plus, learning how to caulk windows is quick and easy. 

Shutters

Installing exterior shutters costs an average of $70 to $350 per window. It’s a DIY-friendly method to soundproof windows that will create a visible barrier between the outside world and your home’s interior.

Sound-Dampening Curtains

Depending on their thickness, sound-dampening curtains can cost $20 to $400. They help make your space quieter by absorbing sound and reducing echoes.

How to Save Money While Soundproofing Windows

Soundproofing your windows yourself is the best way to save money on this type of project. You’ll also spend less cash if you choose materials like acoustic caulk or foam plugs rather than paying the cost of a replacement window. Keep in mind, though, that these DIY soundproofing methods won’t be as effective at blocking out noise as a new, professionally installed window.
