Methods For Taking Down Inner Window Stops?

This article provides a detailed guide on how to install window stops, specifically for Andersen® 400 Series Casement windows. The author assumes that inside stops are removable and window inserts are sized to the inner jamb, resulting in a 1/4 inch gap all around. The first step is to remove the old sash from the window frame, which can be done by prying off or unscrewing the interior wooden stops to remove the lower sash. If you plan to reinstall the stops, follow the instructions provided in the YouTube video and written instructions below.

The second step involves cutting and removing lower sash cords or springs, removing the old bottom sash, and prying out parting stops at the head and sides. Carefully pry or unscrew the interior stops that hold the lower sash in place, using a utility knife to cut through the paint without damaging the stops.

The window casing trim nails to the top of the piece, making it difficult to remove these pieces without pulling the entire window casing. Use a thin blade to gently work your way up until the trim easily pulls loose. Place the blade against the inside face of the frame, towards the end of the stop, and firmly thrust the blade-edge between the frame and the stop. Slide a small flat pry bar between the putty knife and the old stop, then pry loose the old stop with the pry bar.

After removing the entire window casing, adjust the window frame to ensure the studs are plum and square. Apply a window wrap to the new window and follow the instructions provided in the YouTube video and written instructions.
