  • The lower/dodgier end of window fitting relies upon wedges to set the window unit straight/square then expanding foam to fill the void to the wall. This is trimmed and the external beading fitted. Parents' neighbours' kids once came down in the early morning only to find no tv/video, (shows how long ago this was).
    No sign of break in.
    Thieves had silently cut through foam, removed window unit, purloined easily saleable goods and replaced wndow unit.

    Check your window frames to see if there are any sizeable screw heads showing.
    Any idea how old your window units are?
