Steps:

1. Begin by measuring the dimensions of your existing sliding glass door frame. Use these measurements to purchase a new door that fits snugly within the frame.
2. Remove any trim or molding around the old door using a pry bar and screwdriver. Carefully detach the door from the frame, taking care not to damage surrounding materials.
3. Inspect the opening for any damage or rot. Repair or replace any damaged areas as needed. Clean the opening thoroughly to ensure a proper seal with the new door.
4. Position the new sliding glass door into the opening, ensuring it is level and plumb. Use shims to adjust the door as needed to achieve a perfect fit. Once the door is properly aligned, secure it in place by screwing it into the frame.
5. Apply exterior caulk around the edges of the door frame to create a watertight seal. Use insulation foam to fill any gaps between the door frame and the opening, helping to improve energy efficiency.
6. Install weatherstripping along the top and sides of the door frame to prevent drafts and improve insulation. Make sure the weatherstripping is securely attached and forms a tight seal when the door is closed.
7. Before finishing up, test the door to ensure it opens and closes smoothly without any obstructions. Check for proper alignment and make any necessary adjustments.
8. Once the door is installed and sealed, replace any trim or molding that was removed during the process. Use screws or nails to secure the trim in place.
9. Tidy up any debris and properly discard or store any unused materials. Enjoy your newly installed sliding glass door and show off your craftsmanship.
