What Is the Average Cost to Install Windows in 2024?

Window Installation Cost Factors

Many factors can influence the final cost of installing new windows in your home, such as size, energy efficiency ratings, accessibility to the project site, and more. 

Size

There are many types of windows, each available in various sizes. The price varies significantly depending on the size of window you choose. Generally, small windows (2-by-3 feet or smaller) range from $100 to $400 per window. Medium windows from 3-by-4 to 4-by-6 feet cost between $200 and $800 per window. Windows larger than 4-by-6 feet start at $700 and go as high as $3,000 per window.

Number of Windows

Sometimes, the price per window decreases slightly when you install multiple windows in a single project. Unless you’re only interested in the cost to replace window glass for a single window, it’s best to calculate the approximate total for all the windows you’ll need installed.

This is especially important to consider for new builds and whole-home renovations. You can save a fair amount if you invest in multiple windows at the same time. Here’s what you can expect to pay for window installation depending on the number of windows.

Glass Type

Beyond the window type, you’ll also have to choose the glass itself. The more panes your windows have, the more you’ll pay per window. The same goes for special features and coatings. Smart glass installation costs can run an extra premium, for instance. Here are the most common glass types to choose from:

• Single-pane: The most inexpensive type of window, made with one pane of glass. Offers the least energy efficiency. Single-pane windows cost between $150 and $450 per window.

• Double-pane: Two panes of glass (sometimes with an insulating gas in between) for improved energy efficiency. Double-pane window installation costs between $450 and $1,000 per window.

• Triple-pane: Three panes of glass for even more energy efficiency. Triple-pane window installation costs between $500 and $2,000 per window.

• Low-E coating: These windows have a transparent coating that reflects solar radiation, improving energy efficiency in hot climates. They cost about $600 to $3,100 per window.

• Gas fill: These are double- or triple-pane windows filled with inert argon gas, which greatly improves efficiency. They cost anywhere from $600 to $3,100 per window.

Accessibility

Windows in hard-to-reach places will be more expensive to install than those in a readily accessible position. For instance, skylights can be relatively expensive because of the extra labor, equipment, and safety measures needed to install them. 

Brand

Certain window brands cost more than others. Here are a few of the most popular brands and their average cost per window.

Energy Efficiency

Energy-efficient windows are more expensive upfront but pay for themselves in energy savings and home comfort. You can choose windows with improved energy consumption, such as low-emission (Low-E) glass, argon gas filling between panes, and triple-pane windows. 

Reputable glass brands offer energy-efficient features and the Energy Star label on most windows. Energy-efficient windows can help reduce your energy costs by around 12% per year over their lifetime.

Additional Window Installation Cost Factors

Beyond size, type, and brand, a few other factors influence the cost of installing windows. 

Customizations

Custom-designed windows cost more than ready-made ones. You might need a custom-shaped bay window or an extra tall window for a room with high ceilings. Any window that deviates from standard design costs more, which you should consider when making your budget.

New Construction vs. Replacement

An important cost factor with window installation is whether you’re installing an entirely new window or simply replacing an old one. For replacement, you’ll need to pay to buy and install the new window (assuming it fits the space), which costs between $300 and $1,650.

However, installing a window where there wasn’t one before—as either part of a new construction project or a major renovation—incurs more costs. New window installation requires framing, siding, finishing work, and possibly rerouting plumbing or electrical lines. These factors can drive the price of a new construction window as high as $5,000 per window, though it could be more or less depending on the project's complexity.

Labor

On average, labor costs between $100 and $400 per window, or about 15% of the total project cost. If your window is custom designed, requires reworking of the wall to fit, or is in a hard-to-reach position, this cost may increase.

Window Installation Cost by Type

The type of window you install greatly affects the project's final price. For example, skylight installation costs more than a simple picture window. Here’s what you need to know about the different types of windows.

Picture

Picture windows are simple, paneless windows that maximize the view and let plenty of light into a space. They cost between $500 and $1,300 per window.

Single-Hung

A single-hung window has two sashes (or panels), one of which opens. It’s the most affordable type to replace, costing about $200 to $600 per window.

Double-Hung

Double-hung windows look like single-hung windows, but both sashes can be opened. They cost between $400 and $1,000 per window to replace.

Casement

Casement windows feature hinges on one side, allowing them to swing open like doors using a handle or crank. They cost $600 to $1,200 each.

Sliding

Sliding windows move side to side on a track, opening wide like a casement window while taking up less space. Depending on size, sliding windows cost between $250 and $1,800 each.

Skylight

Skylights are placed in the ceiling to let in extra light. They’re harder to access and install, which means they’re more expensive at about $800 to $2,500 each.

Storm

Storm windows are installed on one side of a regular window to offer protection from weather damage while boosting energy efficiency. They cost about $150 to $500 per window.

Jalousie

Sometimes called louvered windows, this type features parallel rows of glass (or acrylic slats) that can open and close like blinds. They’re best for adding ventilation to a room and cost about $175 to $550 per window.

Hopper

Hopper windows tilt downwards from the base on hinges, providing ventilation for basements and bathrooms. They cost about $200 to $700 to per window.

Egress

Egress windows are designed to open wide enough to act as an emergency exit. Egress window installation costs about $700 to $4,000 per window.

Bay

Bay windows protrude from the home’s wall to create a glass alcove space. Due to their more complex installation, bay windows cost between $1,800 and $4,000 each.

Bow

Bow windows are similar to bay windows but have a less-defined curve. A bow window replacement costs between $1,800 and $4,000.

Window Installation Cost by Material

Different materials for your window casing cost more than others, so it’s important to factor them into your budget.

Window Replacement vs. Repair

Window repair is usually cheaper than replacing the window itself. If you notice drafts, leaks, or persistent condensation between panes, it’s possible that only the frame needs to be repaired. Window repair costs vary depending on your location and the issue, so it’s best to contact a local window repair professional to determine your best course of action.

Does New Window Installation Increase Home Value?

Installing new windows can significantly increase the value of your home, especially if you invest in energy-efficient materials. New windows add beautiful natural light to the home and can greatly reduce energy bills thanks to their ability to hold in heat during the winter and keep it out during the summer. New window installation can have as much as an 85% ROI.

Budgeting for Window Installation

Window installation is a worthy investment, but it can be expensive. Here are a few ways to reduce costs when replacing windows in your home:

• Choose affordable window types whenever possible. For example, you can lower window frame replacement costs by opting for vinyl or aluminum over wood and lower the cost of windows by choosing single- or double-hung windows.

• Consider doing multiple installations at once. Most window installers charge a lower labor rate for large projects, and some might even combine window and door costs for further savings.

• Look into federal tax credits for installing Energy Star-certified windows and skylights. You may be able to claim up to 30% of installation costs for a total of up to $600.

• Your local utility company may offer further tax credits, rebates, or other incentives for installing energy-efficient windows, helping to offset the costs of installation.
