Before You Replace Bay Windows: What Impacts Bay Window Prices
If you want to replace a bay window, the following are some considerations that can ultimately impact your project’s cost. Some of these are only applicable to installing a new bay window, some are applicable to bay window replacements, and some are meaningful to both types of projects.
Size
Bay windows are usually 4–10 feet wide by 3 feet high. When you make your decision, consider the size of your current windows. If the new ones will be larger than the ones you have, that will add to the cost of the project.
Eaves
An eave is the edge of a home’s roof that hangs over the exterior siding. Bay windows tend to be installed beneath a home’s eaves, so it’s important for contractors to measure them for the proper fit. When there are no eaves on a house, a small roof is constructed for the windows.
Sash
Sashes are necessary to keep any window in place, so you need to pay attention to the kind of sash that fits your specific window. For example, narrow windows work best with a casement sash, while double hung windows need larger sashes.
Frame and Glass
Usually bay windows have small frames, although that may differ depending on the type you choose. Also, you should think about the type and color of glass you’d like to use in your windows, as well as the coating the windows should have.
Installation Location
Although these windows can be installed in living rooms, kitchens, bedrooms, or home offices, you should think about the best place to get a bay window replacement. Depending on the size of the room, as well as how much light and ventilation you want, bay windows may not be the right option for certain areas of the house.
Structural Support
Bay windows can add beauty to your home, but they also add extra weight to its structure. As a result, they need to be supported in some way to maintain the structural integrity of the house. Some options for providing support — depending on the type of bay windows you choose and their location — include installing tension cables, tie rods, reinforced concrete beams, or steel braces to secure the windows in place. Otherwise, the home may sag or even collapse from the weight of the windows.
Budget
While replacing bay windows can add value to your home in the long term, it’s still important to consider your budget in the short term. These windows can be pricey, even when you choose the most affordable options, so as you work with your contractor, don’t forget to keep your eye on the budget.
Climate and Material
Just as with other types of windows, you’ll want to work with your contractor to get the right materials for your bay windows based on your climate. Depending on the weather where you live, certain types of glass may work better for these windows to ensure you’re able to take advantage of the energy efficiency these products provide, as well as making your home as warm or cool as you’d like.
Cleaning and Maintenance
To ensure that your windows always look great, you’ll want to do a deep cleaning at least once a year. This not only includes the interior and exterior of the glass, but also the hardware, frames, and screens.
Lifespan
Bay windows have a long lifespan, so depending on the type you choose, they can last between 20 and 25 years. Of course, this also depends on how well they’re installed, so you want to find someone who specializes in bay window installation to decrease the chances of shoddy work shortening the windows’ life expectancy.
