Sash Removal, traditional (final)

Title of Treatment: Sash Removal, traditional
Class of Treatment: [ ] Maintain, [ ] Stabilize, [x] Repair, [ ] Upgrade, [ ] Exception
Type of Treatment: [x] Traditional, [ ] Modern

Condition to be Treated:
Double hung sashes have interior and exterior paint build-up. The top sash is painted shut inside and out. The lower sash has broken sash cords. Stops are nailed on. Parting beads are painted in and split or weak.

Description:
Remove upper and lower double hung sashes, interior stops and parting stops from opening cleanly and safely.

Typical Procedure:

1. Score the paint lines of the two side and one top interior stop, front and backsides of stops, with a utility knife, working carefully.

2. Pry the stop away from the jamb with a putty knife first and then a flat pry bar with duct tape wrapped around the leverage areas of the pry bar, working carefully. Always pry from the backside of the interior stop to prevent denting the wood from the front and visible joint. Once the stop is away a bit, be sure to pry where the nails are to prevent breakage of the wooden stop.

5. Write the window number and location of the stops on the backside of all removed parts with a felt marker.

6. Remove all finish nails from the backside of the interior stop by prying them out using end cutters or pliers. Remove box or common nails by straightening and tapping them back out.

7. Lift the lower sash up above the interior stool and pull the sash from the jamb. If there are old rope ends, remove them from the sash. Using a felt marker, mark the side edge of the sash to designate which sash opening it's from and that it is the lower sash.

8. Clean the entire opening and floor area with a HEPA vacuum before proceeding to the upper sash.

9. Score the front paint lines of the two side and one top parting beads with a utility knife, working carefully.

10. Score the paint lines where the parting bead and upper sash meet with utility knife and a specialty sash tool with curved edges and teeth that can saw through the paint buildup.

12. Pry the parting stop out of the groove using a flat pry bar and a hammer, working carefully. Embed the corner of the flat pry bar into the parting stop approximately 1/8". Break the parting stop at the meeting/check rail, working carefully. Save a 1' section of the parting stop to be use as a sample in making new parting stop stock. Discard the rest of the parting stop.
13. If the upper sash does lower for removal, use a block of wood and a dead blow hammer to tap around the stiles and top rail. This will assist in breaking the exterior paint build-up holding the sash in place. Pry between the top end of the sash stiles and the frame header, wiggling gently to loose the sash from the paint.
14. Slide the upper sash down beneath the pulleys and pull the sash from the jamb. If old ropes exists, remove them from the sash and fasten the ropes so the weights do not fall.

15. Mark the side of the sash with a felt marker, to designate the window number it's from and that it is the upper sash.

Quality of Results

Best Work:
No dents in sashes or jamb caused by the removal. Sashes marked properly for location and nails removed from backside of interior stop. Glass not broken more than it was before removal.

Adequate Work:
Sashes removed from openings with a dent or two under the interior stop location. Sashes marked properly for location and nails removed from backside of interior stop. No additional broken glass.

Inadequate Work:
Sashes removed from openings with multiple dents and gouges in the wood, sashes and stops. Sashes not marked properly for location and nails removed from front side of interior stop. Interior stops come out broken. More broken glass than before removal.

Looks good, minor edits only.

I've added a line that allows for removal of nail from the front of the interior stop if the nails have bigger heads, like box nails and common nails. Take a look at step 6 and see if that's OK.

Looks like it's ready for the public to me.
