A note on windows that has come up quite frequently. If your paint is chipping and peeling around the windows then you should consider resealing them with painters caulking or a clear silicon caulking. It's an easy process and a do-it-yourselfer can accomplish this in an afternoon.

BTW I do like working for do-it-yourselfers, they see the work that we are doing and realize that the skill set is easy but the training to see where to insulate/air seal is the whole thing. When NRG (energy) auditing a home for a DIY I do enjoy pointing out the things that they can do that I would normally add to an estimate for my own company. I like seeing the click/light bulb go off in their brain and them realizing that some of the work can be subcontracted to them. It saves them money and it saves us time. Got my first blog follower, thanks dad.
