How much does it cost to heat your home in the winter? Do you think you can change the bill? It is possible to make a major improvement by preparing well for cold weather. There is one major component to your home that makes all the difference in the cost of heating it, as well as how comfortable it feels, and that is insulation. No matter how much you heat a poorly insulated home, it will cool down really quickly as soon as the heat is off. While you can’t do much about the insulation in your walls without a major expense, you can do something about the insulation in your attic, as well as, your basement and crawl spaces. Check and make sure that those areas are well insulated and you will notice a big difference immediately. Your windows and doors are also major sources of heat loss. Seal up any cracks and holes by repairing and installing weather stripping.
