Tallahassee has a deep stock of older housing, from the genuinely historic homes of Los Robles and Myers Park to the mid-century houses built as the capital and the universities grew. That era used asbestos widely because it was cheap, fire-resistant, and effective, which is exactly why it turns up in floor tile and its mastic, in popcorn ceiling texture, in pipe and duct insulation, and in old roofing and siding on these homes today.

Intact and undisturbed, those materials are typically low risk. The exposure event is disturbance. A renovation crew pulling up flooring, a storm-repair crew opening a damaged roof or wall, or an owner scraping a ceiling can release fibers that were safely bound a moment earlier. Given how many older Tallahassee homes are renovated and how often storm damage forces the walls open, testing before the work starts is what protects the people doing it and the people who move in next.
