Replacing a Window

Before you start to take out an old window, be sure you have the correct new window ready to go. Double check the measurements to ensure it will fit. At the very least, have a piece of plywood or OSB to cover the opening in case something goes wrong.

1/2-Inch Gap

When a window is placed in a rough opening, it should sit level on the sill and there should be a 1/2-inch gap on the sides and top of the window frame. This gap is filled with a special expanding foam after the window has been fastened properly according to the written installation instructions.

After removing that old window, you have to replace that opening with a new window. The new window with the glass in place will be very heavy. It is best to remove the window panes from the frame. This will make handling the frame a lot easier.

Take the frame and gently tilt it into place and stay the process of leveling and squaring it up. Using levels, get the frame level and plumb in the opening. Use shims to hold the frame in place. Put the window panes back in. This will help in squaring up the window frame. Once back in place, check along the bottom of the windows to be sure the reveal is the same. Now, start nailing the window in place.

Use 10 or 12 penny finish nails in the sides of the frame. Check the window manufacturer's recommendations for the number and placement of the nails. The next step is to place installation around the window frame and cover the outside with special tape to stop air infiltration. Replace the window trim and you are done.

Follow these steps, and take your time. The window replacement project will go quickly and easily.
