Audio Transcript If you have any old or poorly sealed windows, you may need to caulk them. Caulk prevents drafts and keeps moisture from entering, which could cause the paint to peel or the wood to rot. Step one is to gather your tools, a putty knife or scraper, utility knife, a long nail or wire hanger, a tube of caulk, which is generally enough to caulk around an average sized door or window, a caulk gun and a small plastic spoon or ice cream stick.
