How to Build a Bay Window

Bay windows can add charm to any home.

Bay windows are beautiful additions to any home. They fit any style of home and can be used in small areas or in large dramatic picture windows. If you don't currently have a bay window in your home, you may want to know how to build a bay window. Although this is a more complicated home improvement project, it is not entirely impossible. As long as you stick with your plans and make sure to work carefully, you can have a bay window of your very own.

Instructions on Building a Bay Window

Before you begin with the instructions on how to build a bay window, you need to measure the area where you will place your window so you know what size to buy. Make sure you have all the equipment you'll need before you begin, including a helper. This is not a one person job! You will also need to purchase shingles to match your existing shingles.

Here are the basic directions for installing a bay window. You'll need to study the process carefully before beginning so you can install the window with a professional look and no injuries to yourself or the home.

  1. Remove the existing window carefully, making sure not to break the window.
  2. Use a circular saw to cut a space big enough for the new window.
  3. Build a frame for the bay window to sit in.
  4. Add support braces to secure the window.
  5. Have a helper lift the window with you and set it where it needs to be on top of the support braces.
  6. Add shims in the window to make it level.
  7. Add the roof frame and nail it to the frame of the bay window casing.
  8. Place insulation between the roof frame and the window.
  9. Attach the roof sheeting on top of the frame, add roofing paper and then place shingles on the roof.
  10. Caulk the edges to make the window airtight and waterproof.

Of course, these instructions should just be used as an introduction to the process of installing a bay window. You should plan out your project carefully before starting out.

Special Considerations

After you install your bay windows, there are special considerations that need to be made with regard to decorating your bay windows. You should know that standard curtain rods and curtains will not fit bay windows without some modifications.

Before purchasing any curtains, curtain rods and window dressings, you should take accurate measurements of the center panel window and the side panel windows of your bay window. You need to also be careful when you are purchasing mini-blinds or any other window dressing that hangs in front of the window. Roman shades and other window dressings need to be measured carefully so you can be sure to get the right fit.

As long as you measure before purchasing window dressings, bay windows can be a beautiful addition to any home.
