Bow Window Prices | Find Costs & Installation Pricing


Bow Window Prices

Bow window prices encompass a broad price range, but the average price is $1,500 to $3,500 installed. Complex custom projects that involve 6 or 8 bow windows will go well north of this price range. Some of the bigger factors affecting bow window prices include the number of windows involved, the material and dimensions of the frames, the glass package used, the window manufacturer and the overall level of complexity of the installation.

Bow Window Prices On Installation

Bow window prices on installation will typically fall into the $700 to $1000 range, although projects could be priced out as low as $500 or as high as $2000, depending on the specifics of the install. Find out more on Anderson windows prices.

Frame Material

Frame material is one of the most important factors that affects bow window prices. Vinyl tends to be on the low end, composites, aluminum and fiberglass in the middle and wood at the top of the price range. Cladding such as vinyl or fiberglass on the exterior and wood on the interior is also at the high end and is a great way to go because it provides protection outside and beauty inside.


There are many companies that produce this style of window. Some of the most popular include Andersen, Soft-Lite Gorell, Marvin and Pella. Andersen and Pella tend to be some of the most expensive, while Soft-Lite makes a heavy duty exterior vinyl frame with a wood interior that is more in the middle range of prices.

Bow Windows Installation

I need to replace my bow window because it is sagging even though it has support brackets below. Before started my next project, I'm trying to understand why the sagging is occurring.

Danny, many homes don't have proper support beneath the window. When the original bow window was installed, it probably didn't have side support. Brackets obviously provide support, but they need to attached to something strong. For instance, I see a lot of planned homes that used styrofoam or celotex for the exterior sheather. This underlying framing isn't strong enough to support for the bow window and eventually it will sag. Ply wood is a bit better, but really you need something stronger to provide good support.

Without going into too much detail, your installer should take the time to understand what is inside the walls in order to properly reinforce them and hang the bow window. Sometimes the consumer is to blame when they balk at the installation cost. This is where multiple bids comes into play -- if three installers all tell you you need to add support prior to installation, then you know that it's a step you should take to maximize long term value of the bow window.

Six Panel Bow Window

I need to replace my windows fairly soon and have already received some quotes on 15 double hung and 1 bow window with 6 panels, one kitchen window and 1 picture window. My windows now whistle if the wind is blowing. I moved in last year and intend to stay in this home quite some time. I'm looking for good windows, but can't spend a ton of money. I have been looking at Simonton and Great Lakes. Do you have any preferences?

Kory, there are some excellent choices for mid range vinyl window, all of which should be available as pictures (or fixed frame), double hungs and bow windows. The bow windows will simply be made off site and shipped to your home and then assembled as a unit by your installers.

I think Simonton makes a good window, but I would stick with their mid to upper end windows, the Impressions and Reflections series. Great Lakes makes a good window, but I would stick with their premium model, the ecoSmart.

I like Sunrise and you can stick with their Classic frame. Okna makes a great window, but you might have to stick with their low end 400 series (which is still a darn good window). Wincore is similar to Simonton. Milgard and Amerimax have good mid range vinyl windows that you might also want to take a look at.

Get a few bids from some of these companies (obviously not all of them will service your area, so you will have to do a search for each one to see if a local company carries these brands). Collect your bids, compare the prices and quality of the companies, and then make your decision!

Simonton Bow Window Costs

I'm looking at replacing my bow window for my split level home and I don't know which bid is the best. Here is what I have so far.

United Window: $3,800
United Window: $4,100
Simonton Window: $4,650

Jerry, most window companies actually buy the bow box or underlying wood support from one of a few companies, so I'll assume that the quality of the bow window structure is the same. (Some custom bow window projects are made on-site but I'm going to assume this isn't the case here.)

In terms of windows, Simonton is going to be the better option over the United windows. United is considered a low-end brand, while Simonton is considered a good mid range brand. The price difference of $550 isn't that much if you break it down by four or five windows, so I would say the Simonton all the way.
