Sashes in window need to be removed.


Remove the upper and lower sash from the frame opening carefully to not to damage surrounding parts and jamb. This method is successful if one works with patience and fails if one works too aggressively.

2. Remove the rope or chain from the lower sash.
3. Remove the parting bead that is in front of the upper sash.
4. Remove the rope or chain from the upper sash.
5. Label upper and lower sash, jamb with a number on a metal tag to mark its re-installation location.
6. Install plywood to cover the opening when sash is removed.
7. Tape the window stop and parting bead together and leave it at the window opening.

• Metal tags with stamped numbers
• 1/2" plywood
• Screws

Quality of Results

Best Work: Window sash are numbered, location numbered, window stops and parting beads are taped together and placed into the window location. opening is covered with 1/2" plywood and is keeping the weather out

Inadequate Work: window stops and parting beads are broken, windows are not numbered for re-installation

OK, this looks great: direct and brief.

David, your patience/aggressive comment is excellent.

Can you provide a comment on how best work and inadequate work can be recognized by someone supervising this work?

Ok John, we now have two standards for sash removal, Davids and mine. Both are compatible. Mine is more detailed. Will you combine the best of the two two? Do you think mine is too detailed? Is Davids too brief? How will you handle this?

I think combining them. I could edit some of the details out of yours to make it shorter, then add in a few of David's best points.
