Cost by Bay Window Type
Letโs first look at how the type of bay window you choose affects the price. A simple box bay window is the cheapest bay window installation type due to its simple 90-degree angles and lack of curves. Itโs relatively simple to install. Types such as bow and circle bay are more complex to install due to their heaviness and curved panels and are, therefore, more costly.
Hereโs how each type averages:
Bay Window Type | Average Cost for Window Type | Average Cost With Installation |
---|---|---|
Box Bay |
$750โโ $1,200 |
$1,125โโ $1,350 |
Canted Bay |
$1,050โโ $2,800 |
$1,500โโ 4,200 |

$2,700โโ $4,800 |
Bow |
$1,600โโ $4,800 |
$2,400โโ $5,300 |
Bay Window Cost by Size
Bay windows are considered quite large, so they cost more than traditional window styles. Theyโre custom-built and can be as small or big as you want, but they are typically between 3 feet and 10 feet wide and 3 feet and 6 feet high. The larger the window, the more it will cost. Weโve calculated bay window costs based on some typical sizes below.
Window Size | Average Cost for Window | Average Cost With Installation |
---|---|---|
4-feet-by-3-feet |
$400โ$1,000 |
$700โ1,800 |
6-feet-by-3-feet |
$500โ$2,000 |
$900โ$3,500 |
8-feet-by-3-feet |

$950โ$4,000 |

Cost by Bay Window Frame Material
Whether you choose a low-maintenance vinyl or a rich wood, material costs must be considered when creating your window budget. Here are prices for some of the most popular window frame materials.
Window Frame Material | Average Cost for Materials |
---|---|
Aluminum |
$500โ$2,200 |
Vinyl |
$700โ$3,500 |
Fiberglass |
$900โ$4,500 |
Wood |
$1,100โ$6,000 |
Steel |
$1,600โ$7,000 |
Aluminum
Aluminum is often the most cost-effective material option for bay windows at around $500โ$2,200. Itโs durable and lightweight, but itโs best suited for homes in warmer climates since aluminum isnโt a material that insulates well.
Fiberglass
Fiberglass has a midrange cost of $900โ$4,500. Itโs durable, long-lasting, and energy-efficient. It holds up well in humidity and doesnโt require extra support, so itโs relatively low maintenance.
Steel
Steel is incredibly strong and durable. Itโs also not as susceptible to corrosion as some other materials. Itโs easy to customize, and its strength allows for a super thin frame that maximizes your window space. These benefits make steel the most expensive frame material option at $1,600โ$7,000.
Vinyl
Vinyl is a more affordable option at $700โ$3,500. Itโs also low-maintenance and durable. However, vinyl may warp in prolonged hot weather, and itโs not easy to customize since it typically comes prefabricated.
Wood
Wooden window frames are expensive, averaging $1,100โ$6,000. This is due to their architectural appearance, curb appeal, and ability to be easily customized. Wood windows expand and contract based on humidity and temperature, though, and can crack and peel over time. They may be beautiful, but they can require the most maintenance.
What Other Factors Affect Bay Window Cost?
If you have a roof that extends out around your home, your bay windows may be protected from heavy rain and snowfall. If not, your windows will be unprotected from the elements and could sustain long-term damage. You may need to install a separate roof for your bay window for added protection. Many homeowners match their bay roofs to their homes to create a unified look. Costs vary by material and design.
Window projects can cause some disruption to your home, both inside and out. Youโll likely be left with waste from removing the former window and frame if youโre replacing it and construction materials from performing the installation. Some window contractors include a fee in their labor estimate for cleaning up the jobsite and properly disposing of waste materials. Check with your contractor beforehand to see if they include this and the expected cost. If not, youโll need to consider expenses associated with handling cleanup and disposal yourself. This may include renting a truck if your vehicle canโt accommodate you or paying a service to take the materials away.
Donโt skimp on opportunities to add energy-efficiency upgrades to your windows, such as coatings and extra weatherproofing. The Department of Energy estimates that heat gain and loss through windows are responsible for 25%โ30% of residential heating and cooling energy use. Although energy-efficient bay windows cost more, youโll save more on utility bills in the long run. According to ENERGY STAR, you can save $27โ$197 on your energy bills annually by upgrading to ENERGY STAR-certified double-pane windows. Look for multipane windows and efficient window frame materials. You can also use energy-efficient glass with a low-emissivity (low-e) coating and argon gas to improve insulation.
Itโs important to consider how you want your windows to function. Though most bay windows have a fixed window in the center with two side windows, you can change the design and incorporate functioning windows.
For example, some homeowners use opening casement windows instead of fixed picture windows to allow for better air circulation. Other designs use double-hung windows for each part of the bay window. Adding non-traditional window styles to your bay windows will increase your costs.
Installation costs can increase window prices by 40% to 60%. Bay windows are more expensive to install than other window types due to their size and complicated design. Most window installers require additional help for bay window installations, and the installers will need to cut a hole in your exterior wall. Your bay windowโs location also impacts labor costs, as installations on higher floors require special equipment and tools.
You may need a permit to complete an external build on your home. Your installers may file the paperwork for you, or you might have to do it yourself. Check your local city and county regulations before starting a bay window project.
Installing new bay windows is more expensive than replacing existing ones, as installation companies charge more to cut a hole for a new window. This could double your individual window costs depending on your project size. Companies such as Renewal by Andersen offer affordable bay and bow window replacement options, though bay replacement window prices are still high.
Sometimes, removing an old window reveals structural issues within your wall. You should complete these repairs before installing a new window. This could run you an extra few hundred dollars for small issues or as much as a few thousands for more major issues to load-bearing walls.
Bay window availability varies between window brands. Pella, for example, offers bay and bow windows in five different product lines. Other companies such as Simonton and Andersen sell bay and bow windows in various materials, sizes, and customization options. Product availability depends on the window manufacturer in your area. You should also consider that more popular, name-brand manufacturers will cost more than local alternatives.
How To Save on Bay Windows
These windows cost more than other window styles due to their size and multi-window design. Below are a few tips for keeping the costs of bay windows on the lower end.
- Compare quotes: Get quotes from multiple companies to find the best deals. Many window manufacturers offer discounts for new customers. You should also compare customization options and warranty coverage.
- Limit your installations: Bay windows are a beautiful addition to any home, but costs can increase quickly with the more windows you install. Limit your bay window installation to rooms with frequent traffic, such as a kitchen, living room, or den. You can also use a bay window as an accent piece for your homeโs exterior.
- Low-cost window materials: Wood bay windows are elegant but expensive. Consider cheap window replacements and materials to maintain a reasonable budget.
- Negotiate your final price: Some window companies are open to negotiating installation prices. If your quote price seems too high, negotiate for a lower price. You can also use other quotes as leverage for a better deal.
Can You Install a Bay Window Yourself?
Although you can install many other window types on your own, building a bay window is too complicated. Bay windows are large, hard to maneuver, and require cutting into your walls, so hiring a professional window installation company is best. A window installer will have the necessary tools, experience, and additional hands to complete the installation properly. Youโll also get the added protection of a labor warranty to cover any faulty installations or workmanship issues.
A professional window installer can recommend the best windows for your project and ideal locations for the installation. Theyโll provide an itemized quote and a project timeline. Itโs important to research your prospective installer, review their previous jobs, and verify their credentials. We donโt recommend working with an unlicensed window installer or contractor.
