Nancy, what kind of ventilation fixes besides dryer vents have been successful? Do you do these through weatherization programs?
It depends on the home. Sometimes the fix for ventilation is cost prohibitive for a large, old building that is part of public housing for instance. To the best of my knowledge the weatherization program has been used for window replacement - but I would need to get more detail of additional resource they currently provide. It varies with funding. Sometimes ventilation can be as simple as fixing an existing fan in a bathroom or kitchen and/or ensuring the resident uses it when necessary. If ventilation is lacking part of the education is about lifestyle to compensate for the lack of air flow (e.g., hanging wet clothes to dry in the home)
