How Much Do Soundproof Windows Cost in 2025?

This article was updated using automation technology and thoroughly reviewed for accuracy by HomeAdvisor Editor Ryan Noonan.

Soundproof windows cost an average of $900 per window, with most homeowners paying between $300 and $1,500 per window. On the low end, you could pay as little as $100, or up to $1,500 on the high end. 

Factors like your chosen soundproofing method, project size, and window type affect the total cost. If you're tired of outside noise disrupting your peace at home, installing soundproof windows can significantly reduce noise pollution. Hiring a window professional for soundproofing ensures optimal results and may include the benefit of a warranty.

Soundproof Windows Cost Factors

Other than the window type and soundproofing method, several other factors might affect the cost of soundproofing windows. Below is a look at how each factor affects costs.

Window Location

The location of windows can affect labor costs and, thus, total project prices. Windows that are harder to get to and work on, such as those located on upper levels, will incur higher labor costs than ground-level ones.

Project Size

The size of your windows significantly impacts the cost of soundproofing, ranging from $100 to $1,200 per window. Larger windows require more materials and labor, which increases the overall project cost. If you're considering installing larger window types, you may also need to obtain a permit.

Materials

Material costs for soundproofing vary widely depending on the soundproofing method. For example, window foam plugs and curtains can cost less than $100, while replacing your current windows with new double-pane or triple-pane soundproofing windows can cost several thousand dollars per window.

For a full window replacement, you’ll also need to budget for framing materials, which ranges from $100 to $2,740.

Labor

Expect to pay between $100 and $800 per window for labor. Total labor costs for soundproof windows vary depending on the project complexity. Larger and more complicated window types, like bay and bow windows, will incur higher labor costs.

Labor rates can also vary greatly depending on where you live. Expect to pay more if you live in an area with a high cost of living.

Insulating Gas

When installing double-pane and triple-pane windows, the type of gas between the glass panes (argon, krypton, or xenon) can affect the material cost of the window. Argon is the most affordable option since it's more readily available, while xenon is the most expensive option. Xenon is the densest of the three gases and offers the best thermal and sound insulation. Krypton presents a middle ground between argon and xenon in terms of both price and insulation capabilities.

Soundproofing Cost by Window Type

Several types of soundproof windows are available, including double-pane, triple-pane, and laminated glass. Below, we will examine the features and costs of each option.

Double-Pane Glass

Double-pane windows cost between $350 and $850 per window for materials and professional installation. They consist of two glass panes separated by a space filled with an inert gas—usually argon, xenon, or krypton—to provide thermal and sound insulation.

Triple-Pane Glass

Installing triple-pane windows costs between $400 and $3,540 per window for materials and labor. These windows come with three panes of glass with a space between each pane that houses an inert gas. The addition of a glass layer with an insulating gap increases the level of thermal and sound insulation.

Laminated Glass

Laminated windows cost $10 to $20 per square foot and can reduce noise pollution by up to 75%.

Cost by Soundproofing Method

There are several ways to soundproof windows, with the price for each method varying significantly. At the low end of the price range, you can soundproof your windows with foam plugs or sound-dampening curtains. On the higher end, you can replace your current windows with soundproof double-pane, triple-pane, or laminated glass.

Window Foam Plugs

Foam plugs are an affordable soundproofing option, costing between $25 and $75 per window. These sponge boards fit snugly into your window frames to block, reflect, and absorb sound. Plus, they're easy to install and remove yourself with no professional help needed.

Sound-Dampening Curtains

Sound-dampening curtains, costing between $50 and $200, depending on thickness, offer a budget-friendly way to reduce noise. While they may not block as much sound as window inserts, they're versatile—you can hang them anywhere in your home to help dampen noise. Keep in mind that they also block light when covering windows, which can be perfect for bedrooms or media rooms.

Window Inserts

Window inserts cost between $250 and $500 per window and are another reasonably priced way to soundproof your windows. They involve installing a new soundproof window within the existing window frame, typically on the inside. This helps filter more noise without incurring the cost of a full window replacement.

Full Window Replacement

Replacement costs vary by window type; double-pane windows cost between $350 and $850, triple-pane windows between $400 and $3,540, and laminated windows cost $10 to $20 per square foot.

Installing a complete replacement unit requires removing almost every window element. You'll also need to budget for the cost of replacing window frames, trim, and sometimes even the siding. Full window replacements can be expensive, but they're a more effective and long-term way to soundproof your windows.

DIY Window Soundproofing vs. Hiring a Pro

If you're on a budget and don't mind a bit of outside noise, DIY options like foam plugs and sound-dampening curtains are cost-effective and easy to install yourself.

However, if you're aiming to block out as much noise as possible, hiring a professional to install double-pane, triple-pane, or laminated windows is your best bet. Professional window installers have the tools and expertise to ensure proper installation, minimizing gaps that could let in sound. Plus, professional installation often includes a warranty for added peace of mind.
