Tracking Hidden Moisture In An Old Brick Apartment

Send us Fan Mail 79% humidity inside a rented apartment while the air conditioner runs is more than uncomfortable. It’s a building telling you something is wrong. We unpack a real investigation where a tenant in an old brick, slab-on-grade apartment in German Village feels increasingly sick, suspects mold, and needs answers that go beyond a quick test and a shrug. We explain how we approach indoor air quality testing and mold inspection as a team: one of us focused on sampling and lab results, the other focused on moisture mapping and the building-science “why.” You’ll hear what elevated moisture in drywall can mean, why dampness showing up higher on a wall is a red flag, and how exterior details like a raised flower bed against brick, peeling paint along the bottom courses, and poor grading can drive moisture intrusion through capillary action. We also talk through realistic fixes, from correcting drainage to reducing brick wicking when a full vapor barrier rebuild isn’t practical. Then we get honest about testing: why swabs can come back “hot” even when air samples are not elevated, what common molds like Alternaria, Penicillium/Aspergillus types, and Cladosporium suggest, and why “the air test is normal” can be a dangerously incomplete conclusion. We close with what to look for in a qualified mold assessor or home inspector, plus an important warning about ERMI and HERTSMI being misused for residential mold and moisture assessments. If you care about health symptoms at home, moisture control, and getting defensible answers from indoor air quality and mold testing, listen now.
