The first step in any job is to make sure you have the proper tools available for the job. In addition, if you are enlarging the space the previous window is in, or if you are cutting a hole to make a completely new window, you will need two by fours as "cripple studs" and other framing that may be needed. Then you need to follow the steps to a proper installation:



1. Determine exactly how you want the window placed in the wall and remove the existing window. Using the measurements of the new window, draw the outline on the outside of the house. This will show you where you need to cut. With your circular saw, cut the required opening.

2. Build a frame for the new window. You may have to cut through existing studs and install a new header, sill, jack studs

and cripple studs.

3. Put in support braces. Bay windows are usually pretty wide, so you need to use the number of braces accordingly. A five

foot window, for example, will need at least two braces, a wider window three or more.

4. You will need an assistant to lift the window and set it in place. You balance the window on the support braces and slide it

into the opening. Put in shims to level the window perfectly, and then anchor it in place by nailing it down.

5. Place the roof frame over the bay window and nail it into place. Insulation must be put in between the roof and the top

of the bay window, using the insulating material of your choice. Attach the roof sheeting to the frame and then put down the

roofing paper. Put in drip edges and flashing, then put shingles on the roof of the window.

6. Fill insulation around the bottom of the window between it and the wall of the house. Attach a skirt bottom that will serve

to seal the window on the underneath.

7. All of the edges should be sealed with outdoor grade silicone caulking to keep the window airtight and waterproof.

This is the basic list of installation steps for a bay window. The steps have been abbreviated to give you an idea of what steps you need to be prepared for, but if you buy a preassembled window, it will include detailed step by step instructions.

The best way to insure that you have a properly installed window is to follow these instructions to the letter. NO shortcuts! Your project will be faster and easier in the long run. I asked two friends to help with the project and that helped make the project go faster, especially since we have done projects together before. In one afternoon, we had removed the old window and put in the rough framing for the new window. We covered the hole with plywood for protection overnight, and started working early the next day. By the end of the second day, the window was in, including the roof and skirting. The following day I was able to seal up the outside and complete the interior trim.

Our prediction was true; we picked the ideal spot to install a bay window. It was a charming touch to the outside of the house, and on the inside of the house it was a conversation piece in the room. It definitely added character to the room and we know it will add to the resale value of the house, since this is a feature that has been shown to be very desired by home buyers.
