Arched windows are stunning, unique features that can bring an air of elegance to your home. To get one of these beautiful windows for your home, you’ll need to spend an average of $660 per window, including installation costs. Most arched window installations cost from $355 – $1,005.

Professional window installers will likely charge around $95 in labor fees per arched window, depending on its size.

Although arched windows were popularized by Roman architecture, these curved windows are used in varied styles, from Mexican and Victorian-style, to Baroque, Rococo, and Art Nouveau, to Spanish Colonial, Gothic, Romanesque, French eclectic, and even modern builds. Whatever style your home is, an arched window will fit in.

This article covers the following:

Average Arched Window Installation Costs

National Average Cost$660
Typical Price Range$355 – $1,005
Extreme Low-End Cost$195
Extreme High-End Cost$4,000

On average, installing a single arched window costs about $660, but homeowners can expect to pay anywhere between $355 to $1,005 per arched window. However, you can spend as little as $195 or even more than $4,000 on your arched window project, depending on several factors. 

Why the huge price difference? Arched windows come in many different shapes and sizes, and each version has its own price point. For example, a homeowner installing one small half-round window will spend less than someone who wants to install multiple large Palladian windows. Although they are almost always custom, a few ready-to-install models are available. 

Here’s how you can save money on your arched window installation:

  • Install smaller windows
  • Use windows made with budget-friendly materials
  • Install fewer windows
  • Install multi-window arches
  • Get multiple quotes from different contractors to find one that fits your budget

The quality of the window you buy is the most important cost factor, but the window frame, glass, size, type, design, and labor fees also affect the overall cost of your window installation.

Also known as half-moon and radius windows, arched windows are arched at the top and rectangular at the bottom. These windows come in different price points depending on the quality of the window.

Arched Window QualityCost Range
Budget-friendly$325 – $515
Mid-point$425 – $750
High-end$750 – $1,100

You can divide these price points into budget-friendly, mid-point, and high-end:

  • Budget-friendly arched windows are usually small, fixed, come in standard sizes, and are made of vinyl.
  • Mid-point arched windows can come in wood-clad, aluminum, composite, fiberglass, or even quality vinyl window frames. These can come in standard sizes or be custom-made.
  • High-end arched windows are usually large, have wood-clad frames, and have high-quality glass. They are often custom-made.

Here is a list of prices you can expect to pay for your arched window installation based on the quality of your window. These prices include labor fees.

Other Factors That Affect Cost

There are many other factors that affect the cost of an arched window installation. These include the style and type, window frame, window glass, size, and labor cost. Keep these factors in mind when you’re trying to plan your arched window home improvement project.

Type and Style

Arched windows come in different styles, each with its own pros, cons, and aesthetic appeal. Some of them are large, while others are small enough to fit above other windows.

Fixed Arched Windows

These are any type of arched window that doesn’t open. Used heavily in churches, fixed arched windows provide lots of natural light, but no airflow at all because they are inoperable. Many arched windows are fixed.

Opening Arched Windows

In contrast to a fixed arched window, an opening arched window is operable; it can be opened to provide ventilation to your home. Opening arched windows can come in a double hung window or casement window style, with casement windows being the better option for airflow, unobstructed views, and escape during an emergency.

Opening arched windows are usually more expensive and require more maintenance.

Multi-window Arches

Instead of a single big window, multi-window arches are several windows arranged to look like an arched window. Multi-window arches are commonly made with multiple rectangular windows with a smaller half-moon window on top, which help them mimic the aesthetic appeal of true arched windows. Using separate windows also makes it easier to create specific looks.

It’s often less expensive to install multi-window arches than true arched windows. However, they require more maintenance, especially when compared to fixed arched windows, and they can’t be weatherproofed as effectively.

Half-round Arched Windows

These are smaller windows shaped like half-circles or semi-circles. They come in different types. Many of these can be installed above other types of windows.

  • Elliptical arched windows:  These are wider semi-circles commonly installed above large windows and patio doors.
  • Half-elliptical arched windows: These are one-half of an elliptical arched window.
  • Quarter circle arched windows: These windows are half of a half-round arched window.
  • Full chord arched window: These windows look like the top one-third of a circle, creating a look similar to an elliptical arched window, but more curved.
  • Full arch heads: These arched windows have corners, looking like rectangles or squares with curved, arching tops.
  • Half arch heads: These are shaped like full arch heads cut in half vertically.

Palladian Windows

Dating back to the 16th century, these windows feature one large arched window flanked by smaller windows. They are also called Venetian windows, and they make for great focal points that add a lot of visual interest to your home both inside and out. Palladian windows are usually more complicated and more expensive to install than other arched windows.

Window Frame

Another cost factor you have to consider is your window’s frame. It can be made of different materials, with some being more expensive than others. They each have their own strengths and weaknesses.

Here are some of the window frame materials you can choose from:

  • Vinyl: Vinyl is your best bet if you want to save on your arched windows. Many standard arched windows come in vinyl. It is an insulating material that’s relatively sturdy and low maintenance.
  • Wood: Used in many custom arched windows, wood is a timeless material that can be customized however you like. Wood can even be clad in other materials, like vinyl, fiberglass, and aluminum. However, wooden arched windows are quite expensive and require more maintenance.
  • Fiberglass: Fiberglass windows are durable, energy-efficient, and low maintenance. This material is more expensive than vinyl.
  • Composite: This window material combines wood’s aesthetics and vinyl’s durability, energy efficiency, and low maintenance requirements. Composite windows are generally more expensive than vinyl.
  • Aluminum: Aluminum arched windows are often custom-made. They don’t dent or scratch easily but aren’t very energy-efficient.

Aside from your arched window’s material, your arched window can be customized further with different frame styles or grids. Some of these styles are diamond, prairie, fan, thirds, sixths, and quarters.

Window Glass

Homeowners can choose to have special glass treatments for their arched windows to increase their energy efficiency. Some of the glass variants you can choose are double-glazed, tempered, low-E-coated, tinted, and laminated. They will make your arched window more expensive up front, but they will lower your energy bills in the long run.

Your arched windows can also come with more glass panes, up to three panes in total. Double-pane windows are more insulating than single-pane windows, and triple-pane windows are even more energy efficient than double-panes. However, these additional panes will cost you more.


Most arched windows come in widths ranging from 24 inches to 192 inches. The general rule of thumb for window size also applies to arched windows: the bigger the window, the more expensive it will be to install.

Labor Costs

Most professional window installers will charge around $95 in labor fees for an arched window. However, expect labor costs to increase significantly with the size and complexity of your arched window.

Arched Window Replacement Cost

Replacing arched windows is typically more affordable than installing a new one outright. This is especially true if the new window is the same size as the old one, since no additional work will be necessary to reshape or refit the frame. The average cost of an arched window replacement ranges from $345 to $925.
