Even the smallest gaps and holes can have a big affect on heating and cooling costs. Weatherstripping and caulking are easy, inexpensive ways to help reduce energy costs.
- Seal windows with caulk as a simple, inexpensive DIY project. You can save 5 - 10% on energy costs.
- Seal doors with weather stripping. $50 in weatherizing can reduce heating costs by two to three times that much.
- Install DIY foam gaskets or insulators behind all outlet covers and switch plates, especially those on exterior walls. Be safe and shut off the power to outlets and switches before you get started.
- Use expanding foam to seal openings around water spigots, air conditioner hoses, dryer vents and gas pipes.
- If your home has single-pane windows, use and close heavy draperies at night during winter to help block cold air. Open drapes during the day to let in the warm sun.
- Install storm windows. They help keep your home warm in the winter and cool during the summer. It’s not a difficult DIY project and can save you up to $330 a year.
- Weatherize and insulate attic access. Pre-built, DIY kits are available at many retailers.
