The 9 Steps To Installing A Window For Your Home

1. Remove The Window Trim And Casing

Using the pry bar, remove the trim and jamb extension (piece of wood leveling the jamb with the wall).

2. Take Out The Old Window

Unscrew and remove the window. For windows with multiple sashes, it may be easier to remove them one at a time.

3. Prepare The New Window Opening

Inspect the opening to make sure there is no damage like rotting. Any damage needs repairing before you can move forward.

Measure the opening to ensure it’s wide enough. It should be 1/4 – 3/8″ larger than the dimensions of your new window.

Any gaps can be filled in with insulation later.

4. Look At The Window Stop

This part of the window keeps it in place so it won’t fall out. It is a piece of wood around the outside of the window jamb.

It may be damaged and in need of replacement.

5. Test Fit The Window

Before adding any adhesives, make sure the window fits into the opening. It should be quite a snug fit.

6. Install The Window

1. Run silicone along the inner edge of the window stop
2. Slide the window in
3. Level the window
4. Screw it in where marked

Now you get to make everything look neat and beautiful.

7. Add Insulation To Any Gaps

Here is where you can add in the insulation to any openings or cracks around the original window frame.

8. Add Jambs And Trim If Needed

Find the trim that fits your style and add it to the edge of the window.

1. Measure the length of each part
2. Cut the trim using a miter saw
   • 45-degree angles
3. Attach to the wall with finish nails

You might need to add thin strips of wood (jamb extensions) inside the original frame to cover the gap.

9. Finishing Touches

This includes painting, filling holes, and making sure it fits your ideal look.
