How to Repair a Bow Window
Projection windows are a staple of residential architecture, providing awe-inspiring views and bringing in natural light. They can be costly, though, particularly in the case of wooden frames or are found in old homes.
Even for those with extensive knowledge of home construction, they are difficult to install. This is due to the fact that they usually require structural modifications to walls and work around electrical wiring.
Support Brackets
Bow windows can look beautiful in a home, however they can be prone to sagging if they're not properly supported on the top and bottom. It could be due to them being heavy, or even if not because they are facing outwards, which makes them more vulnerable to gravity.
Use of support brackets beneath the base is the best way to repair bow windows that are sliding. Hardware stores carry these brackets, which can be pushed slightly up under the base of the window, especially where the sagging occurs. This will help distribute the weight of the window to the brackets supporting it and, consequently, it is less likely to slide in the future.
It is also essential to ensure that the support brackets are securely attached to the wall. If you're using screws that are meant for these kind of brackets and you want to attach them to the wall. This will ensure that they stay securely in place so that they don't be pulled away from the wall again.
Another solution for a bow window that is sagging is to install a support cable under the top of the window. This will remove some of the weight from the top of the window and will also distribute the weight down the wall and into the foundations of the home. This will help to reduce the window's sagging and can be done without making major structural changes to your building.
If your bow window is sliding towards the middle, it's likely because the hinge on top is misaligned with other frames. The hinge is bent due to the fact that it is required to support the weight of a massive window.
Support Cable
Bow windows are gorgeous ways to add extra floor space to a room, and also let sunlight into. Bow windows unlike bays supported by platforms and foundations, rely on their weight to stay upright. This can cause them to bow over time. This can make windows difficult to open or close, and could cause them to become crooked. If your bow window is sagging, it's important to determine where the problem lies so that you can make an informed decision on what you can do to fix it.
Installing a support cable is the first step to fixing the bow window that is sagged. These are metal rods that run between the window's frame and the other end is fastened to the eye at the top of the window while the other end is fastened to the wall of the house (this could be a joist, or a wall stud, based on how your home was built). If you connect an extension cable to the bottom of your bow window it must be tightened so that it partially lifts the sag away from the window. You can even put in two of these cables to ensure that each one takes half the weight off the window, which will prevent windows from becoming too uneven.
If the bow window is sagging at the top it is likely that the frame over time has warped or cracked which makes it difficult to open and close. This can affect their energy efficiency, and could be a sign that the frame is leaking or is draughty. In this situation, it is best to repair the bow window before the damage worsens.
It's important to know that repairing or replacing the bow window is a complicated process, and will require structural work within your home. If you're working on a home that is historic, it's always best to employ a professional window contractor who is knowledgeable about the types of windows that are installed. They can assist you in deciding whether you want to replace your bow windows and can make sure that the installation is done correctly and safely.
Repairing the Cable
Bow windows aren't incorporated into the structure as bay windows are, and are susceptible to sagging. A support cable absorbs some of the weight of the bow window and spreads it across the walls and into the foundation. You can purchase the kit from a local hardware store, which includes an appropriate cable as well as the tools to screw it tightly to the wall. A kit is a cheaper alternative than buying the cable separately.
First, you will need to determine the location where sagging is taking place. If commercial windows bow is at the bottom of the frame, you might require a new sill plate, while bowing outwards may require some additional brace bars. You will need to determine whether the bow window can be operated or not. Operable windows require the sash be raised, which could add a significant amount of weight.
Once you've identified where the sagging occurs then you will require an extension cable. Make sure the cable is tightened enough to lift a small portion of the weight, but not too tight that it snaps. It is a good idea to fit two cables to ensure that one is able to take half of the weight while the other one supports the remainder of the window.
The installation of a new header could be necessary when the sagging is close to the ground. The header is made up of two two-by-eights which can be quite heavy. You must carefully take measurements and calculate the length of the header, since it needs to sit precisely between the king studs. You will require several people to assist you in lifting the header.
Close any gaps around the bow window and add insulation. This will decrease the amount of cold air that leaks into your home. It is also necessary to install soffits on the outside of your home. It can cost anything between $250 and $765, depending on the size of your home.
Fixing the Brackets
Bow windows can add style and class to any home. They are similar to bay windows but do not have to be built into foundations. Instead they can be hung on the wall, just like any other window.

The first step is to identify where the damage is occurring. You can do this by taking a look at the bottom of the window. You will need to fix the problem if you find that the sagging is due an insufficient support at the bottom.
You'll need additional brackets for this. These should be fitted underneath the bottom of the bow window and they should look like small L-shaped shapes with middles that are thickened. Then, you'll need to install these brackets on the wall, and then you can connect an extension cable to them. The cable will carry a portion of the weight from your bow window and spread it down the wall into the foundation.
Once the cable is installed it must be tightened. Be sure to make the cable as tight as you can however, not so tight that it damages the glass or window frame. Once it's tight you'll notice that the bow windows are lifted.
If the window continues to slide, you may have to add additional brackets or cables to support it on the other side.
