Aluminum isn’t high-end, but it’s a very functional material. Your window will usually have a mid-grade quality if you choose to use it with other materials being more durable overall. However, it can be a top pick in different scenarios. Aluminum is very strong and lightweight, and it’s very durable against more salty air like around oceans or beaches. It works very well in warm climates because it won’t disintegrate or erode in the slaty air or heat and humidity. Your bay window prices using aluminum range from $400 to $1,200. 


Clad windows come in two main types, aluminum and vinyl. You can also choose fiberglass, but this isn’t as common. A clad window is a window that comes with different interior and exterior materials. The interior core is typically wood. 

This type of window will give you the weather-resistance and durability you get with aluminum or vinyl windows while giving you a classic interior look. Since the material changes, these windows are more likely to build up condensation between the glass panes.

PVC or Vinyl

You do get a small window to customize them, but this is lower than more versatile materials. It’s weather-resistant and durable, and it insulates the window very well.

There are several unique designs you can choose from, and the structure and design will depend on what type of window it is. Each different type has a slightly varied function with different price points, including: 


This is a slightly different shape than a typical bay window, and it usually comes with four or five panels for the glass instead of three. The more panes give the window a much more gentle curve. The panels are also much slimmer than a traditional one, and they come set at winder angles. Your bay window price for a bow-style window ranges from $900 to $1,600. 


The panels on this bay window will have a 90° angle on them. When you put all three panels together, they form a rectangle or box shape.

Your bay window price for a box-style window ranges from $500 to $900 for the window alone. 


A circle bay window is on the high end of the price spectrum, and they have a full curve to them that helps to create a half-circle when you look at the window panes. They typically come with three panes of glass, and you’ll see a very ornamental design with a lot of intricate details like carvings, patterns, or coloring in the molding. These windows are also usually taller than a traditional bay window, and they can easily get between six and eight-feet tall. Your bay window prices will range from $2,000 to $3,000 with this design. 


Better known as a canted bay window, this design uses three panes. Two of the panes are angled. The third pane connects the two angled panes and has a flat design. The panes sit at 30° and 45° respectively. They tend to be wider and taller than traditional box bay windows, so the costs usually go up. Your bay window prices fall between $800 and $1,100. 


This was the original form for bay windows that goes back to the English Renaissance period. They get built not to touch the ground, and this is their design key. Instead, they have a decorative bracket that works as a durable structural support for your window. These windows lend a very classic look and feel to your home, and you can add them to any floor.

Labor Costs

Labor will play a large part in your final bay window price estimates when you call companies in your area. Generally speaking, this is a more labor-intensive project that can take several hours to complete. At minimum, you should add around $400 in labor per window, and the maximum cost can easily top $5,500. The national average is $2,400, and you have to add this to your bay window prices. If it’s a complex installation, you’ll pay more for it. 

Cost to Replace a Bay Window

Replacing an older window is less labor-intensive and faster than installing a whole new one, and this can help you control your bay window prices. The bay window price will be the same for the window itself, but labor will drop. You normally won’t have to alter the roof or eaves if you already have a window and place and just need a new one. 

If you already have a window in place and you want to replace it, your bay window prices typically include four to six hours of labor at $160 to $240. This doesn’t include material disposal, and this can add $50.00 onto your costs. By the time you factor in preparation, travel, and disposal into your bay window prices, the cost falls between $500 and $700. All you have to do is buy the window and schedule an installation date. The contractor will pull out the old one, check the eaves and walls for damage, and install the new window. 

Cost to Repair a Bay Window

Bay windows will typically need one of two repairs. A faulty seal is the most common problem that can appear between the window frame and the glass or between the wood trim and the window frame. A faulty seal can lead to leaks and problems with insulation. Your bay window prices will go up when you include this cost, and it usually takes two hours to fix at around $100. 

The second issue is a damaged roof, eave, or sill. They can happen outside if you had a bout of bad weather go through, or normal wear and tear can cause them. If you need to fix the bay window roof, it usually costs around $500 and takes eight hours to finish. 

No matter which repair you need, it’s a good idea to call in a professional who can figure out which issue you have and fix it quickly. If the repair is small, it shouldn’t take long or be too difficult to fix. Contractors usually charge the same rates for installation or repairs, but the repair costs are usually much lower. 

Additional Cost Considerations

Along with the typical costs, there are a few additional ones you want to factor into your bay window prices. Some of them are optional and some aren’t optional, so you want to have ballpark costs for both to help you budget effectively. 

Energy-Efficient Glass

Today, most of your standard window glass is very energy-efficient. If you live in a cold climate, you may want to have Low-E coating or triple-insulated glass to keep the cold air out. It could boost your energy efficiency by as much as 20%. Your bay window prices for a standard double-hung bay window made out of vinyl will range from $270 to $800 a window. 

Interior Trim with Window Seating

Adding trim to the interior is a nice way to finish the window and get a clean look. You could add a seating or storage area, or a window frame. It could be a good idea to hire a carpenter to come in to finish it, even if it’s relatively simple. Per linear foot, your trim will cost between $3.00 and $4.00. To hire a professional to come in, you’ll spend around $350. 

Open the Wall

It’s a very large project to open a wall on your home to add a bay window. You have to spend a decent amount of time on the construction and preparation. Depending on where you want the window, your contractor might have to move load-bearing walls and studs. This usually takes several days to complete, and it’ll add between $1,200 to $3,000 to your bay window prices. The cost continues to go up if it’s not on the ground floor. 

Remove Old Windows

You have to remove the old window before you can replace it. Some companies will include the removal in the original quote and some don’t, so it’s important to confirm this detail when you call around to local companies. This process usually takes around an hour from start to finish, and your costs will range from $80.00 to $130.
