What Is Building Biology?

New Construction

How important is the relationship between our health and our indoor environment? Can natural building materials really make a difference in our homes, offices, and schools? Building Biology studies these questions and offers 25 guiding principles for safe, health-supporting building practices. See our article explaining What Is Building Biology? to find out more!

Mold Survival Stories

Have you experienced a serious toxic mold exposure or know someone who has? These stories will encourage anyone walking through this difficult valley. Read the accounts of several fellow travelers who have made it to the other side in our Mold Survival Stories.


  • Ryan Shellenberger and Family

    We built our home in 2003. We wanted to grow old and die there. The home tried to speed up the process.

    During construction, roofers cut corners. As a result, water slowly leaked into the ceiling and walls. We never saw it, but there was enough to start mold and bacteria growth. By the time we learned of the problem, our family had paid the price.

  • Erik JohnsonIn 1986, Dr. Paul Cheney asked me, "How would you like to become a prototype for a new syndrome?"

    I refused, saying that my improvements due to staying out of moldy buildings would distract from his theory that our illness was caused by a virus.

    But Dr. Cheney insisted. So I became a participant in the study group that led the CDC in 1988 to recognize the illness that they named "The Chronic Fatigue Syndrome."

  • Lisa Petrison

    I became ill with Myalgic Encephalomyelitis (aka Chronic Fatigue Syndrome) in 1994. By 2007, I was near-comatose all the time, with dozens of symptoms.

    Finally I learned about toxic mold and did a trial away from my home and possessions. After that, I reacted violently to both the house and its contents. The house did have black mold hidden in it.

  • Kristina Townsend - Virgin Islands

    I was exposed to high levels of toxic mold while in the Virgin Islands in 2007. I was there for my job and was housed in a building that had been condemned two years earlier.

    The key to my survival was the testing offered by Real Time Labs. The tests confirmed a diagnosis of mycotoxicosis, which helped me understand the nature of my illness. It also helped me address the real issue and get the medical help I needed.

  • Gregory Muske

    Tearing apart moldy kitchens and bathrooms was just another day at work.

    My health declined over decades. Eventually, I completely broke, in part because of being steeped in mold spewing from our new front-loading washing machine.

    Conventional medicine had no answers. I spent two years thinking I was going crazy, while researching on my own for 40-60 hours a week.

  • Christa Upton and Family

    "What is that smell?" I asked my friend when she visited our newly purchased 1970s house. I'd been working on getting the smell out of our carpet for three months.

    "Christa, I think it's mold."

    We ended up spraying and "killing" a massive amount of mold that was hidden under the carpet, behind baseboards, etc.

    Eight months later I was bedridden and very ill, and no one knew why.

  • Betsy Anderson's House

    I fled. We had sudden, extreme exposure when our landlord tore up floorboards, releasing a toxic mess from the crawlspace and spreading it through the house with a fan. Fled to a tent in the yard within days, then fled to hotels. Searched for a year for a safe place for my family. Ultimately, fled not only the house and all belongings, but the country (England) for a drier climate.

  • Heather Plude

    My son went from normal kid to disabled kid in about six weeks. Starting when he was 11 and for about nine months, he was having trouble walking, playing, eating, drinking, and sleeping. He was in terrible pain and couldn't go to school.

    Our whole family was sick. Finally I read the book Surviving Mold. An ERMI test on the house came back high in toxic molds.

  • Janis Bell

    When I was 13, my family moved into a house with a basement that flooded regularly. I developed endocrine and immune symptoms.

    At age 32, I moved to a town where mold was ubiquitous. My office was in a sealed building that allowed the toxins from animal cages and molds in the basement to spread through the central HVAC. I watched my health decline despite visits to many doctors and was disabled at age 44 with the diagnosis of ME/CFS.

  • Kelly Connor

    After 10 years of CFS/CFIDS, I began to remember mold exposures from the time before I got suddenly and increasingly ill in middle age. I realized that I had been having a Stachybotrys toxin reaction. As I remembered mold in various former dwellings, I began to get rid of possessions from those times. Gradually, I gave away treasured books, plants, rugs, clothes, and papers.

  • Grateful Grandmother

    I bob and weave.

    In 2008 I realized our home of 32 years was full of hidden toxic mold. I was too. My husband wasn't. The more I tried to save our home, the more ill I became, and our marriage as well.

    We moved to a hotel for six weeks and remediated the entire house, but not me. The house was clean, tested by the best. We disclosed everything, threw away everything, and sold the house.

  • Giles Meehan

    There wasn't any connection that I could see between mould and my debilitating ME (CFS), acquired after graduation from the University of Cambridge in England. Rest and various treatments (chiropractic, diet, supplements, etc.) had helped somewhat. I lived near the sea in Felixstowe, long renowned for its fresh air.

    I made some videos, then Erik Johnson commented that some people with ME don't experience those awful "crash" symptoms after everything they do, if they are really free of mould. So I started looking into that.

  • Beatrice Latherings' Trailer

    I survived because of two people on the Internet, plus the support of friends and family.

    The first Internet person nailed my problem as mold and persisted in convincing me. I thought I had Lyme disease and had never heard of mold illness.
