Sash Removal and Repair:

No window sashes may be removed before the painted and weatherstripped wooden storm is installed. Before installing the storm window ensure the exterior window casings, exterior sill and exterior portion of the window jamb have been stripped, primed, caulked and finish painted.

Remove all interior sash stops, parting stop, metal weather stripping in jambs and both window sashes from the opening and mark for location in a way that will remain intact through paint removal.

Retain parting stop for reuse if it is in satisfactory condition. Retain all interior stops for reuse. If an interior stop is broken/damaged on a unit, all pieces for that unit should be discarded and a new interior stop shall be installed for the entire unit. Replace parting stop with pine to match size of original.

All window sashes that have metal jamb liners shall be restored to their original sash and weight configurations. These units will require new or salvaged pulleys that match the originals to be installed. If sash weights are in the weight pockets they may be reused, however if they are missing, new sash weights that are half the weight of the finished sash shall be installed in each weight pocket for each sash.

All functioning sash pulley shall be reused. Damaged/non-functioning sash pulleys shall be removed and repaired or replaced with a new or salvaged pulley that matches the originals.

If rotted wood exists on the interior side of a sash and it will be finished naturally, new wood shall be spliced in and finished to match surrounding wood. If a sash is disassembled, DO NOT glue-up the mortise and tenon joints when re-assembling. Clamp mortise and tenon joints and joint stop snuggly, and pin the joints with two hot-dipped galvanized finish nails that have been cut off shorter than the thickness of the sash into the mortise and tenon joint at opposing angles. Provide new parting and interior stop as needed to closely match originals.

Repair double hung jambs, side sliding wood tracks, sills, exterior trim, muntins, and interior stools as needed with wood or exterior architectural epoxies.
