Things You'll Need:
- Putty knife
- Screws
- Caulking (latex)
- Ladder
- Portable electric drill
-
Step 1
Measure the window frame and the window space to ensure the window will line up and fit properly. Use a putty knife to remove glue or old caulking from the window space before installing the window. If the window to be installed is used, ensure that it, too, is free from old glue and caulking that could prevent a good fit.
-
Step 2
Tape the new window on both sides with masking tape in the shape of an "X" in case of an accident. While this won't stop all the glass from shattering, it will help contain some of the glass, which helps with clean-up and prevents accidents.

Step 3
Run a bead of latex caulking all around the window frame to ensure the window frame is waterproof and has an airtight fit.
-
Step 4
Hold the window by its frame with the help of your buddy and maneuver the new window into the window space. Using the portable drill, insert each of the screws into the window frame, being careful not to over-tighten. Screws should be snug-fitting.
-
Step 5
Replace the window trim all the way around the window frame, securing it with screws. Test the window from the inside of the building to make sure it opens and closes easily. Remove the masking tape from both sides of the window and clean with window cleaner.
