I charge a flat rate for basement window installation – call for details.  These are replacement windows, which do not require any removal of framing.  Rather, they slip in to the existing opening.  This particular window is a Northview vinyl hopper tilt-in window with 3/4″ insulated glass.  It comes standard with a screen and costs about $90 (labor not included).  As part of the process, I shim, caulk, and form a mortar sill to allow for water run-off (as seen below).  Give me a holler!
