Sometimes it is necessary, or at least desirable, to replace existing windows. Adding windows is a job that anyone with basic carpentry experience can usually handle. However, the process can get difficult at times. Ductwork, a plumbing vent, or a chase-way for electrical wires may be located in the same place you want to put a new window. Local code requirements might insist that new windows be added as the use of space is changed.
There are a wide variety of window styles from which to choose. Double-hung windows are the most common type; single-hung windows are not used very often. Casement windows, awning windows, bay windows, fixed glass, and bow windows are some additional types.
Cutting in the rough opening for a new window can be a little tricky. However, once the wall is opened up, framing the window opening is pretty simple. Examine the structure of the wall before including major wall changes. Some windows are held in place with a nailing flange. The flange is set against the exterior wall sheathing and screwed in place. The wall studs of balloon-framed houses carry the load of the second floor and roof cutting into them may be best handled by a subcontractor. Siding is installed over the flange. Not all windows have nailing flanges. Some windows are made so that they are nailed into place through their sides. Follow the manufacturer’s recommendations when installing any window.
When preparing to cut in a new window, it is important to remember to start on the inside of the building. If you work from the inside and discover something that could prevent the window installation, you need to only patch interior wall, but if you start the work from the outside, you have to fix the siding and sheathing, which is a much larger project.
Since the window hole has been cut out on the inside wall, you can see if there are going to be any problems installing the windows in the desired location. If there is no reason to change plans, you can continue with the process.
