The siding is pretty much new. Only a few years old. And I have a bunch of extra if they mess it up.
I've already done the attic. I did it back in 01/02 and also rented the machine myself and my brother and I did it. Blowing it in wasn't hard at all, I just don't think I want to pull off the siding, drill 100 holes, etc.
Also, when the idiots did my siding, they didn't wrap it in anything. where the A is on the house (above the ceiling line on both sides), it's nothing but open. They didn't put any board up or foam padding or nothing. I was pretty pissed they didn't do it, but oh well.
The windows are new champion too (back in 01/02). If you came over to the house today and felt the wall, you can just feel the coldness radiate off it. Then if you did the downstairs, it's night and day difference.
