Mold Is the New Asbestos: Why I Think Bi...

Mold is quietly turning into the new lead paint/asbestos scandal and I’m here waving a giant, slightly gross flag about it. I walk through why big volume builders like D.R. Horton and Lennar are getting slammed with lawsuits — bad HVAC sizing, poor framing, and homes built so tight they sweat themselves into unlivable molds. I riff on the Dixon case in Louisiana (buyers from 2014 pushing back, state court standing and a potential class action stretching back to 2007) and the Seminole Tribe litigation in Florida where 450 homes and a thousand tribal members are dealing with defective roofs and moldy walls — damage estimates topping the hundreds of millions. The numbers get my attention: Horton’s $1.1 billion self-insurance reserve and Lennar’s 21% bump to $336.9 million tell you insurers and builders are already feeling the pain; jury verdicts north of $10M rose 52% between 2023 and 2024. I don’t buy “just maintenance” as an excuse — undersized HVAC, poorly ventilated attics, and wet lumber are failures in basic building science, not bad luck. I also talk about the human cost — property values tanking (one Texas house plunging from $318,700 to $117,000 when mold was disclosed) — and why legal, insurance, and construction practice pressures are converging into what could be a long, expensive reckoning for national builders.

Takeaways:

• We warned mold is becoming the new lead paint — builders are ignoring humidity, and that's a systemic failure.
• I walked a Lennar job with wavy walls and undersized HVAC systems, proving sloppy framing and poor load calculations aren't isolated oopsies.
• We talked legal fireworks: the Dixon vs. D.R. Horton fight stayed in Louisiana courts and may expand into a class action reaching back years.
• I pointed out insurers and builders are quietly padding self-insurance reserves into the hundreds of millions, because construction litigation costs are rising fast.
• If you're buying new, we insist the punch list is 100% done before closing; seriously, pay for pre-drywall inspections and someone to manage the build, don't take their BS.
• Mold testing is a circus — spore counts and remediation estimates can vary wildly, resale values can plummet, so get proper air quality tests from pros like Caroline Blazowski before you panic or sign away rights.
