Q:
My three-year-old son has had a runny nose for the past year, and now has an eye allergy. His doctor said it could be due to mold in our apartment. We can’t see any mold on the newly painted walls, but can smell and feel the humidity as soon as we walk in. The owner won’t do anything about it, but I need to protect my son. I appreciate your advice.

Improper ventilation can lead to the damp environment that mold loves best, and this could be a primary issue in your apartment. However, an air quality professional will be able to give you the best and most thorough assessment of the conditions and what can be done.
