Properly controlling moisture in your home is important

Properly controlling moisture in your home will improve the effectiveness of your air sealing and insulation efforts, and vice versa. Thus, moisture control contributes to a home’s overall energy efficiency. Be sure to use humidifier in winter and dehumidifier in the humid summer months.

The best strategy for controlling moisture in your home depends on your climate and how your home is constructed. Before deciding on a moisture control strategy for your home, you may first want to understand how moisture moves through a home.

Moisture control strategies typically include the following areas of a home:

  • Attics
  • Foundation
    • Basement
    • Crawl space
    • Slab-on-grade floors
  • Walls.

In most U.S. climates, you can use vapor diffusion retarders in these areas of your home to control moisture.

Proper ventilation should also be part of a moisture control strategy.
