With the window out and the area cleaned up, it's time to prepare the new unit and put it in.
First, unpack the new window. Some suppliers have them shrink-wrapped or otherwise protected. All this has to be removed. On vinyl windows there is a movable trim piece on top that can be adjusted to fit the opening better, and sometimes the manufacturer packs other things under there. Mine had a trim piece for the bottom outside of the window to cover the gap caused by the slope in the sill. Some may put a package of screws for fastening the window in place (this one had the screws packed with the instructions, between the lower sash and the screen). While you still have it out, look for the holes the manufacturer provided for the installation screws; this window has 4 on each side. Vinyl windows have the two sashes, set in a vinyl frame with the spring balances in place, ready to go, usually with a screen on the outside surface.
|Next thing is a trial fit.|
Pick it up, line it up and set it in the space and see how it fits.
|After seeing this, I
chose to put the top trim back on. Then take the window back out. Cut
the bottom trim for the outside to the width you need with snips and
install it. |
Before installing the window for keeps, put a bead of caulk on the blind stops
