Replacing Sliding Glass Door with French Doors


  1. Remove pieces of trim around the door frame, pulling them out with a hammer. Do this carefully if you want to reuse them in your new door, or delete them if you plan to buy new trim.
  2. Use your hammer to remove the nails holding the door unit to run in place. There are probably several in each shoulder but check for nails on the head of the frame as well.
  3. Discard the door unit to run carefully. If it is in good condition, consider donating it to a rescue building installation for reuse.
  4. Measure the size of the rough opening for your new door. This is the dimension of the stud to stud transversely, and the finished floor to the top of the opening, lengthwise.
  5. Buy a set of pre-hung French doors using the measurements you took in Step 4. Your door, including frame, should be about 1/4 “smaller on each side than the size of the rough opening. Pre-hung French doors are available at most home improvement stores.
  6. Slide the French doors in the opening, bottom first, making sure it is centered on the space. Doors should be placed so that they will swing away from home once installed.
  7. Use your level to ensure the unit is even and plumb. If not, place wood shims between the jambs and framing members to level it out.
  8. Fix the unit in place by fixing three nails at each stop. Be sure to also preach any shims you used the posts or frame.
  9. Place insulation in cracks along each stop. Batt insulation is the easiest to install and should fill the space without being forced.
  10. Install trim kits around the frame to cover the isolation and complete the project.
