Detroit sits in a unique moisture zone where Great Lakes humidity meets continental weather systems. Summer dew points regularly exceed 65 degrees, the threshold where indoor moisture problems accelerate rapidly. This humid air infiltrates homes through every opening, overwhelming HVAC systems not designed for high moisture loads. Winter creates the opposite problem. When outdoor temperatures drop below 20 degrees, interior humidity condenses on cold surfaces, particularly in older homes with single-pane windows and minimal wall insulation. This freeze-thaw cycle damages building materials and creates persistent condensation issues that cheaper solutions cannot address.
The city's housing stock compounds the challenge. Over 60 percent of Detroit homes were built before 1960, before building codes addressed vapor barriers or mechanical ventilation. These homes were designed to breathe naturally through construction gaps, but modern weatherization traps moisture inside without providing controlled ventilation. We understand these older homes because we work in them daily. We know where moisture hides, how it moves through balloon framing, and what solutions work within existing construction. That local knowledge prevents expensive mistakes and delivers humidity control that lasts.
