we have been in our house a little over a year now ... Last winter we replaced the back sliding glass door, the gasket under the front door (since I could see out). This summer we have replaced the roof. ( it was prob a 20 yr shingle on a house built in 78 and we wer the first to redo it). I can't wait to see how that is going ot help this winter. We have a very large window in the livingroom that I wanto put plastic on but I have to talk dh into it. Also in the bed rooms. We have a split level home and we spend about 90% of the time up stairs so we close almost all the vents off downstairs. We vent the dryer into the main room down stairs (we bought a kit that you attach to the line to switch it from in room to the out side line). We also bought a mattress warmer and are going to be buying on for dd this year since she is no longer in the crib.

You need a Door Sweep- you can get them at HD or Lowes. Measure your door width before you go, they come in several sizes.
Then, when ready take the door off,lay it on a blanket and fasten the sweep to the botom and re-hang the door. With two people it should be done in less than 30 minutes. It took me about 90 minutes- I had to get the old one on the bottom off and thought it would be easy...it wasn't. Putting the new one on took a couple of small nails and done! Now, re-hanging the sucker was another matter.
