Sealing gaps and cracks can improve your home's heating or cooling by up to 10%.

Plus, it's a simple job that only involves a little bit of work. Gaps and cracks around windows and doors allows air to sneak into your home during the winter, causing heating and cooling systems to work harder.

Here are four simple projects that can help draftproof your home:

  • Foam weatherstripping

  • V-seal weatherstripping

  • Window insulator film

  • Outlet insulator pads
