How to Repair a Bow Window
Replacing bow windows can add value and energy efficiency to your home. The cost of the windows will differ based on the material used for the frame and glass options.
Triple-pane or double-pane windows can be insulated by Krypton or Argon. Insulated glass can reduce cooling and heating costs.
Support Cables
Stained glass windows depend on stainless steel cables to transfer tensile force from the window frame to the structure above and below. They are arranged in the shape of a parabolic to resist wind loads. Over time, these cables can develop a stress pattern in which they bow outward, sometimes surpassing the brace bars that partially block bowing inward. This can be caused by settlement in the building or temperature fluctuations, as well as the oxidation of the window's lead and breakage of the wire ties that join the window to the brace bars. The out-of-plane bowing alleviates the pressure on the framework as well as the stained glass to prevent further damage. It also lets the window be free of the confinement lead, making it more weather-resistant. However, it can be hazardous working on these windows if they aren't properly secured.
Add a Wrap
The addition of a bow window to your home can provide panoramic outdoor views, a spacious feel and a unique look. Because these windows extend away from the home and are exposed to the elements, they can be sagging or distorting. If a window with a bow becomes unbalanced, it could affect the structural integrity of the roof and glass and can cause structural damage to the house. There are a variety of ways to fix the bow window until you can have the glass replaced by professionals.
The first step is to identify the area where the sagging occurred. If it is in the middle you can install support cables in an L-shaped shape at the base of the frame to lift the window a bit and distribute its weight evenly. If the sagging is in the top or bottom, you will need to insert support brackets.
If the glass is in good condition you can also put on an extra layer of wrap to reinforce it. Cut a painter's wooden stir stick to size and then cover it with wax paper to shield the glasses. Wrap the stick around the bridge of the glasses, crossing it as required to make the wrap thick. Leave window doctor bow to be cut later and soak the wrap in glue prior securing it to the glasses.
Crash wrap can be found at many automotive and hardware stores. This is a type of clear packaging tape that offers sturdy and flexible support for your glasses. The best part is that it's much simpler to work with than duct tape and is removed easily once the repair is complete.

This is because these kinds of windows require larger openings and might need to attach to structural elements of the home.

Once you have a solid foundation for the window, you can put in the window. Use a bubble level to ensure that the window is centered and straight on both sides. After the window is in place, you can put in a cable kit to help with stability and support. The cable helps distribute the weight of the window down to the wall and helps keep the window from sliding.
It may be a smart idea to put brackets under the base if the bow window is sliding at one point. These brackets can be installed using a drill, and are designed to fit in the corner of your home. Once the brackets are in place, they can be inserted into a wall and placed evenly over the bottom of the window.
