REMOVE THE EXISTING SASH
Note: Remove the new window from its packaging. Inspect
and measure the new window to ensure it will fit into
the opening prior to removing the existing window. The
window needs to be 3/4" smaller in both width and height
than the pocket frame.
A.
Unlock the window.
Raise the lower sash and
lower the upper sash so both are in the approximate
middle of the frame.
Note: Most of the following steps may be
completed from the exterior of the house.
B.
Remove the head parting stop.
Remove any head parting stop by pulling the stop down
from the frame. In some cases, the stops are nailed on and can simply be pulled off. In
other situations the stops may need to be pried or cut out of the frame.
C.
Remove the exterior jamb and head stops.
This can be accomplished with a wood
chisel, circular saw, reciprocating saw, roto-tool, or equivalent. Ensure the stop is
removed flush with the existing window jamb.
D.
Remove the upper and lower sash.
This will vary per manufacturer of existing windows.
Some will simply pull out, while others may need to be cut to be removed. Grasp the
sash and pull out of the frame. The jamb liner material may come out of the frame when
pulling the sash out.
E.
Remove any and all jamb liner material.
Some liners may have frame attachment
fasteners that will need to be removed before the liners can be removed.
Caution: Spring loaded balances can cause injury; use care when removing balances
from existing windows.
