Bay Window CostLast post we talked about the average cost of aluminum windows and now we will cover the average cost of Bay and Bow windows.

This is really thought to narrow down because there are many factors which go into pricing a Bay or Bow window. We will try to give you a sense of what you can expect.

Bay windows are windows that have been specially designed to create a niche or nook in a home that is filled with light. Most often these windows are used to highlight an outdoor view such as a forest, meadow, or the ocean. The bay window often offers a window seat that allows people to sit in them to enjoy a good book.

Bow windows are simply bay windows that are created with a curve or circular shape instead of using angles.

Bay windows are common throughout Victorian architecture as well as many schools of modern design. Adding a bay window to a home can increase the value of the home quite significantly.

Bay Window Styles

There are two basic types or styles of bay windows. The first style simply forms a box that comes out of the side of the house. This type of window is usually used for ornaments or plants. The box is often installed a little below the height of your head and is sometimes placed in a kitchen to offer view and light without upsetting the shape of the house.

The box bay window is the cheaper form of this type of window and is often found in homes which are less expensive or in homes in developments that are all similar.

The other type of bay window is the full bay window. This type of window adds square footage to the house and can be used for art displays, as a window seat, and even for a breakfast nook. The glass needed to fill the space for the window is very large. This creates an abundance of natural light in the room where the bay window is placed.

Where Should Bay and Bow Windows be placed?

Bay and bow windows offer a lot of exposure to the outside of the home. The large size of these windows makes them perfect for rooms in the home that face private areas. It is not a good idea to have a bay or bow windows facing a public street as this type of window offers very little privacy.

If the bay or bow window of the home faces a public viewing area there are some window treatments that are available to help cover up the window and provide you with more privacy when it is desired.

Cost of Bay and Bow Windows

Bay windows are not cheap and the average price for a basic bay window can be anywhere from $1200 to $3000 for just the window. The cost of the bay window will depend on how large the window is and the materials that are used for creating the window frame. The design and style of the window will play an important role in determining the cost of the bay window as well.

Bow windows are considered to be specialty windows as they are not the typical shape of a bay window and are a bit more difficult to create. Bow windows are great because they offer a bit more dimension and a unique look for any home. The average cost of a typical bow window is pretty much the same as bay windows or even slightly more $1400 to $3200.

When choosing the material for your bay or bow windows you will find that vinyl bay and bow windows are quite affordable with the average price ranging from $1200 to $1800. Wood is one of the more popular choices of materials because of its durability and strength. The average cost for wood bay and bow windows is $2000 to $2600.

Fiberglass is one of the newer materials that are available and the cost is a bit higher for this type of bay or bow window. Fiberglass offers flexibility, versatility, great insulation, and is overall one of the best materials for any type of replacement window. The average cost for fiberglass bay and bow windows is $2500 to $3200.

The cost of installation is going to vary based on how the window is going in, is there a window there already, does it involve a roof,etc… I fair range to figure is $1000 to $3000 for installation alone.

Getting the Best Deal on Bay and Bow Windows

When searching for bay and bow windows it is important to do some research. You will want to make sure that you find a reputable installation company to install this type of window. Bay window installation can be quite tricky and is not something that you should attempt to do yourself, unless of course you are a master carpenter.

The installation costs for a bay window are typically determined after the site has been inspected. Many companies offer free inspections, but you must be ready to deal with a strong sales pitch during the inspection.

The cost of the bay or bow window will depend on a number of variations including the location of your home, the skill of the contractor that you hire, and the average wage rates for contractors.

When choosing a bay or bow window, keeping the pattern and configuration simple will save you money. If a complex installation configuration and pattern is chosen you can expect the cost to be between 5 to 14% more.

The great thing about bay and bow windows is that although the initial cost may seem somewhat high, the added value to the home is high as well. This simple addition to the home can add thousands of dollars to the resale value of the home, making the project worth the cost overall.

Educating homeowners on replacement windows and providing simple information to get them a great product at a great price done quickly by a reputable window pro.

  • Brian, I just broke one pane of a double pane window. It is an Andersen window, and I don’t know when it is from. I bought the house in 2007 and it was built in 1966. How much should I get charged for installation? I measured and it’s around 19.5″ wide by 43.5 high. That window is one of four in a bay/bow set-up in the den. It also got me thinking that I would consider replacing all the windows and the wooden frame inside. It looks beaten and weathered. I can show you pictures, if that helps.

  • Joe – What you seem to be talking about is replacing only the broken glass in the window. You will need to contact a glass company to come out and measure the glass for replacement and should run around $150 – $200 for insulated glass. To replace the whole Andersen bay/bow is going to be $5,000 to $7,000 depending on your installation situational.

  • My 4’x8′ simple bay window was quoted between $5400 (home depot/lowes installation not included) to $7200 installed (anderson).

  • That price is high. Get more quotes. The way to get the BEST DEAL is to price the window yourself from a window supplier like HD or a local lumber yard. Then have a local window installer price out installing the window you provide. Make sure he includes removing all the debris. I’ll bet this will save you $2000.


    So this is how you should do it:

    1. Go to a window supplier with the rough measurements of the window you are replacing and get a written estimate of what you are being quoted with as much detail as possible (DO NOT ORDER NOW).

    2. Bring that home and get some quotes from local window installers to install the window. Make sure you show them the written quote you got.

    3. Make you selection on who you want to order the window from and who to install it.

    4. IMPORTANT! Now have the installer you have chosen verify you are ordering the correct window and window SIZE.

    5. Place the order for the window(s) and have them shipped directly to your house.

    If you don’t know who to get quotes from to install the window(s) this link will connect you with local reputable window installers in your area. I have no direct connection with them.

    DISCLAIMER: If you use the link above the installers are paying for the lead (your contact info). So please only use it if your are serious about wanting someone to contact you about pricing your job. I do get a small portion of the lead fee, but hey, I could have potentially just saved you $2000 :).

    Good luck and please let me know how you make out.
