winter days in our house

Today it's very cold! The coldest it's been all winter. When we got up this morning it was 12 below zero.
Hard to keep the house warm. The pellet furnace which we got last yr. runs 24 hours a day when it's this cold. Plus we add some electric heaters. Also we found out our house is soooo leaky! Our front door never has been right. It's a cheap steel door, and it leaks so bad. We've been keeping a blanket on the floor in front of it. I would like to get a new door. One with a pretty window in it. I thought it would be nice if it was forest green like the new garage door.
Our garage door broke last spring. It was an old wooden door that came off the runners and fell apart. It was stuck half way on a tilt. The guy that fixes them, had fixed it so many times that he thought we should get a new door. But a new garage door cost $1300 for an insulated kind.
So we were still thinking about it when a friend was trying to help us make it safer and instead it fell down, almost on him and one of the children. Well we were all done with it now. So thankfully I had a birth that could pay for it and it's so nice we have it for this cold winter. The pipes already have trouble with freezing, but this yr it's so much easier to keep everything above freezing temperature.
So our front door needs replacing too. They costs about $400. Step by step though we will get this house fixed up.
We also noticed around the floor on the garage wall a terrible leak under the trim. It was like a fan of cold air coming through there. So we got out a caulking gun and sealed off the space. I suppose when we redo the living room floor we can cover the space better.
