Certified staff will assess the home by conducting pressure testing and diagnostics to determine building tightness limits. Using blower door equipment, which measures airflow, the leakiness of the home will be determined. This will determine what work can be done to save the most energy. Weatherized homes are inspected to make sure the work is correct and complete.
