After we air sealed and insulated this Warminster, PA customer's home there was no way for the moisture from all the showers that were being taken on the second floor to exhaust. Customer noticed a musty smell after these showers. Upon a revisit and some questions to the customer we discovered the issue and installed a new bath fan to reduce the moisture in the home which will improve over all indoor air quality.
