That part of the house is actually just one story, so I don't think it would be that difficult to get the liner down in there. Did you buy the "whole package"? If so, about how much did it cost, where did you get it from and how much would you have saved if you installed yourself?It's quite nice buying the whole package with installation and in one day it's installed. Plus, it is two stories and I imagine you'll need some help with the liner.
