Weatherizing your home helps you save money by saving energy, and it can also improve the comfort of your home. Professionals who perform weatherization services are part of the "Home Performance" industry.  They are trained to understand how a house works as a system and to offer solutions that can solve common and difficult problems using building science.

Conduct a home energy audit to start building your strategy for weatherizing your home, then learn about air sealing, insulation, moisture control, and ventilation.
