If you’re looking to replace the windows in your house with newer ones but you don’t want to hire an expensive carpenter to do so, this guide is perfect for you. This is a do-it-yourself, step by step guide on how you can replace your windows:

MEASURE YOUR OLD WINDOW:
- Measure the height of your old window.
- Measure the width of your old window.
- Measure both the diagonals of the window.
- If the different between the two diagonals measured in Step 3 is greater than ¼ inch, you need to replace the entire window frame for installing the new window.
Note: When taking measurements, always take multiple readings and choose the smallest.
REMOVING THE OLD WINDOW:
- From the left and right of the window, remove the inside stop pieces. Be careful, do not damage the stop pieces because you will have to reinstall them with the new window. If you damage them, use wood filler to mold them.
- Remove the inside sash of the window frame. This is an easy process, once the inside stops have been removed in Step 1, just hold and remove the inside sash.
- Remove the outside sash by sliding it down to the bottom portion of the window frame. Once it’s at the bottom, remove the parting bead and outside sash
- Clean and prepare the window frame for installing the new window:
- Remove any weights and pulleys on the window frame.
- Remove any screws or nails remaining in the frame.
- Remove old caulking with the use of a utility knife.
- Check for any rotting wood, if there is severe rotting, contact a professional. Otherwise, carry forward.
INSTALLING THE NEW WINDOW:
- Run caulk on the inner parts of the outside stops of the window frame.
- Vertically center the inside and the outside sash of the new window into the window frame.
- Locate the stops and begin to slide them on the middle of the frame. Keep doing this until four mounting holes (found in the side jambs) become visible.
- Place the window into the frame now. Use a level to check if the window is correctly balanced.
- Now put the mounting screws in each of the jambs. There will be four mounting screws and two jambs (one screw will mount of top and bottom of each jamb).
- Check that the window is now working properly and does not have any gaps on the sides.
- Finally, caulk the insides of the window and install the inside stops.
