Why Mold Lawsuits Are Coming Back for Homebuilders

Matt Risinger examines the growing number of mold-related lawsuits involving homebuilders and connects today’s problems to changes in building practices and energy efficiency. He explains how tighter homes, oversized HVAC systems, poor moisture control, vented attics, and inadequate air sealing can contribute to elevated indoor humidity and condensation. Risinger also discusses lessons learned from earlier building failures involving bulk water and flashing, along with practical approaches for builders and homeowners to identify moisture problems. The discussion covers HVAC design, dehumidification, water management, building commissioning, moisture measurements, and the importance of keeping building assemblies dry.
