Start on outside of the window and look for gaps in the joints of the frame, where brick and wood meet, etc.  Use caulk to fill in these areas as a sealant. You can find a clear caulk that you can paint over to keep your window looking clean and neat.  This project can save you from replacing your windows and can give you the most bang for your buck!

Purchase a “draft snake” online or at a home store near you.  Push these against the bottom of your window to seal the window and prevent cold air from pushing through. Best part? You can choose a simple, plain color or make a DIY draft snake with a fabric of your choice.

You can purchase self-stick rubber weather sealers at a home store or online.  These are easy to use and install by yourself.  All you need to do is cut the strips to fit your window, then press them on the window frame inside your home to seal any gaps.
