Matt Risinger chats with Wynn White, a Baton Rouge-based engineer, at the 20th Annual Westford Symposium on Building Science about asbestos, mold, and construction defects. Risinger picks his brain on how to go about gaining a mold-free house and White reminds us that there is really no such thing as zero mold the key is to keep mold from growing in the house. If a home has water problems, it will also have air-quality issues and probably mold issues. The key is to get the home dry, clean any existing mess, and then keep it dry. For a new home, make sure to let the structure dry if it rains during the process of building. When the house is built, the holes created for windows and doors need to be flashed properly. For someone who is interested in building science, using alternate building materials like concrete walls or non-paper faced drywall will also be at risk if they get wet and stay wet. At the end of the day, if any building material gets wet without the chance to completely dry you, your structure will be at risk to mold growth. Tune in for more ways to avoid mold growth, plus some design tips from White.
