Use Caulk to Seal Leaks Before Winter 

Because as much as 80 percent of air leakage occurs in areas other than windows and doors, caulking is an absolute winter necessity.

After determining which areas need attention, it's important to choose the right type of caulk for the job. Before buying or using a particular caulk, read each label carefully for storage and application temperatures. While the factors may be of varying concern depending on personal preference (amount of money you're willing to spend, lengths you are willing to go to to find a certain caulk, time you wish to spend redoing the job in a few years), it is important to check the temperature resistance of any caulk if you live in a very cold climate.
