My first question. I have a small home that I bought a year and a half ago and it needs to be made more energy efficient. The windows are single pane, the roof needs replacing, the walls and attic need insulation, and lastly the central heating and air should also be replaced. Since my funds are limited and I may have to do one project at a time, what would be the first thing I should begin with if I am unable to afford all of this to be done at one time and how do I find a contractor that may be able to perform high quality work with quality materials at the lowest possible cost? The home is only a 2 bedroom, one bath with a single garage and has only 1000 square feet? I don't know what elst to add to the question. Thank you.
