I'm sure this is a stupid question but here goes....
How do you remove windows? I'm thinking of replacing all my single pane
extruded aluminum windows with modern double panes. Looking at the window I
don't see any obvious mechanism for installing them or removing them. Is
all the installation hardware underneath my house siding?
Is it a good idea to let a professions handle this or can a reasonably handy
homeowner handle this him/herself?
