Don't let cash slip through the cracks
When you add up the cumulative effect of all the small leaks in your home, it has the effect of leaving a window open all year long, the EPA's Vargas says.
To save money, you can use inexpensive expanding foam or caulk available at your local hardware store to seal cracks in the following areas where cold or warm air typically escapes. Those places include:
- Around windows and doorframes.
- Around the top of the basement wall where the cement or block contacts the wooden frame, known as the rim joist.
- Around the holes in walls where pipes enter and exit your home.
