Drafty windows can cause your electric bill to jump dramatically during the winter. If you have an older heater it is likely to cost you even more. Older heaters sometimes are just run on heater coils with a forced air fan (now called emergency heat). A strong draft in the house can make your bill jump as much as 15 – 35%. Heat pumps and gas heat is a little more efficient, but you will still lose money letting your warm air slip out your leaky windows.
I found this Dap Seal n’ Peal caulking about two years ago at my local building store and tried it out. It seals the draft for the winter and you can peal it off whenever you feel necessary. To apply it, you need to clean the area of the window you will be caulking with a damp rag (use windex if the area is especially dirty). Let the area dry. Cut the caulking tube just enough to cover the crack and puncture the seal. Get another wet rag ready to clean up any excess caulking. Apply the caulking on the window, and smooth with your finger (lightly wet your finger with the clean up rag). Allow the caulking to dry and test to see if the window is still drafty.
Another thing to do along with fixing the drafty windows is sealing your drafty doors. I will talk about door on my next post.
