Post Storm Damage Caution!


Many across Florida have been directly impacted by the recent storms that wreaked havoc on our beautiful state.


In a recent discussion with Richard "Rick" Morrison, Executive Director, Division of Professions Mold-Related Services Licensing Program regarding the possibility of the Governor waving licensure requirements for mold related services.  Rick felt that the state has enough licensed mold professionals to not recommend waving the licensing requirements at this time.


Those impacted by the storm and in need of water and mold damage restoration should ensure that the contractors providing services are licensed and in good standing with the state of Florida.  http://www.myfloridalicense.com/dbpr/pro/mold/index.html


I also wanted to take a minute to provide a few questions that you can ask your mold assessor or mold remediation contractor before you make the decision to hire. 

 

  • Are you licensed?
  • Who will be providing the mold assessment?
  • Who will be providing the mold remediation?
  • What will my mold assessment consist of?
  • Will I receive a written report or just a laboratory report?

 


The most common mistake property owners can make is to allow the mold remediation contractor to provide the mold assessment.  Mold remediation is a very profitable business. Many mold remediation contractors use free or deeply discounted mold inspections as a means to acquire expensive mold remediation jobs.  This is the beginning of the “Fear” based approach to mold not the “Fact” based professional approach.


Unfortunately, this is a common practice.  The assessment often includes the collection of mold samples and the declaration that the home is contaminated with “Black Mold”.  Sampling of any kind is more often than not necessary and more often than not used to scare the homeowner into believing that their home is contaminated with “Toxic Black Mold” or “Stachybotrys”.  Fear not Fact!


If your mold professional brings up the “Black Mold” issue walk him or her right out the door. 


The Center for Disease Control clearly states, “There is always some mold everywhere – in the air and on many surfaces. Molds have been on the Earth for millions of years. You do not need to know the type of mold growing in your home, and the CDC does not recommend performing routine sampling for molds.”  Fact!


The type of mold will not change the need for mold remediation nor will the type of mold change the severity of the water and mold damage.  There are over 100,000 molds and over 10,000 have the ability to produce mycotoxins.  There are also a few well know molds that are repeatedly used to scare consumers such as “Black Toxic Stachybotrys”.


From the CDC website.  “The term "toxic mold" is not accurate. While certain molds are toxigenic, meaning they can produce toxins (specifically mycotoxins), the molds themselves are not toxic, or poisonous. Hazards presented by molds that may produce mycotoxins should be considered the same as other common molds which can grow in your house. There is always a little mold everywhere - in the air and on many surfaces.”


These “Black Mold” fear tactics began in Cleveland, Ohio, when in 1993 and 1994 where there was a cluster of cases of pulmonary hemosiderosis among infants. with a conducted titled “Study of Toxin Production by Isolates of Stachybotrys chartarum and Memnoniella echinata Isolated during a Study of Pulmonary Hemosiderosis in Infants.”  Yes that is a mouth full but most government studies have grandiose titles.


The problem with the study is that it was preliminary and incomplete.  Worse yet is that most in the mold and restoration industry have never read any of these studies or the final opinions of these studies. 


Below is the final opinion of the study from the CDC.


“A review within CDC and by outside experts of the investigation of acute pulmonary hemorrhage/hemosiderosis in infants has identified shortcomings in the implementation and reporting of the investigation described in MMWR (1,2) and detailed in other scientific publications authored, in part, by CDC personnel (3-5). The reviews led CDC to conclude that a possible association between acute pulmonary hemorrhage/hemosiderosis in infants and exposure to molds, specifically Stachybotrys chartarum, commonly referred to by its synonym Stachybotrys atra, was not proven.”


The CDC Position on Toxic Mold and Stachybotrys.  https://www.cdc.gov/mold/stachy.htm

 

The term "toxic mold" is not accurate. While certain molds are toxigenic, meaning they can produce toxins (specifically mycotoxins), the molds themselves are not toxic, or poisonous. Hazards presented by molds that may produce mycotoxins should be considered the same as other common molds which can grow in your house. There is always a little mold everywhere - in the air and on many surfaces. There are very few reports that toxigenic molds found inside homes can cause unique or rare health conditions such as pulmonary hemorrhage or memory loss. These case reports are rare, and a causal link between the presence of the toxigenic mold and these conditions has not been proven.


Stachybotrys chartarum (also known by its synonym Stachybotrys atra) is a greenish-black mold. It can grow on material with a high cellulose and low nitrogen content, such as fiberboard, gypsum board, paper, dust, and lint. Growth occurs when there is moisture from water damage, excessive humidity, water leaks, condensation, water infiltration, or flooding. Constant moisture is required for its growth. It is not necessary, however, to determine what type of mold you may have. All molds should be treated the same with respect to potential health risks and removal.


US National Library of Medicine National Institutes of Health https://www.ncbi.nlm.nih.gov/pmc/articles/PMC145304/

While many papers suggest a similar relationship between Stachybotrys and human disease, the studies nearly uniformly suffer from significant methodological flaws, making their findings inconclusive. As a result, we have not found well-substantiated supportive evidence of serious illness due to Stachybotrys exposure in the contemporary environment.


Despite the well documented lack of connection between Stachybotrys and health effects, including the CDC, many in the mold and restoration industry continue to use these wild and scientifically unsupported scare tactics to charge for mold remediation services that are unnecessary.  I can assure you that Stachybotrys is in every home and building to some degree or another.  We have been cohabitating with mold since we lived in caves. 


The value in a professional mold assessment is in the identification of the specific area of the mold contamination by a licensed professional that is not providing the mold remediation.  With the identification of the specific area of mold contamination in a written report from your assessor, licensed mold remediators can provide estimates for the mold remediation.


The specific area of mold contamination cannot and will never be revealed by sampling the air and scaring homeowners with specific molds.   The sample only approach to a mold assessment has no value to anyone but the sampler who collects a fee for the sample.  Remember the type of mold does not change the method of mold remediation, does not change the area impacted by mold, and will never elevate the concern for exposure to occupants.  All claims that the type of mold raises the severity are either by the ill-informed or those looking to prey on your fears for profit.

 

A professional mold assessment would include the area affected by the mold as required by the ASTM D-7338.  A professional assessment would report that the area impacted by mold.  For example, the area of mold growth is approximately 4 square feet of the exterior south facing bedroom wall as shown on the attached restoration floor plan and diagram.  Remove the base boards and the drywall from the floor to a height of 2 feet.  The diagram would show the area of affected building material that would require removal.  The type of mold would not matter and would not change the area impacted or the method of remediation.   Fact not Fear. 


Those wanting to insight fear would report nothing more than the spore counts of samples collected as elevated or as having the presence of Stachybotrys “Black Toxic Mold”.  Fear not Fact.


The cost of restoring your home can be greatly increased if you’re not careful when hiring a mold professional.  Be aware of scare tactics, ask for references, never hire anyone that is recommending sampling, never ever hire anyone that uses the term “Black or Toxic Mold”.


I hope this helps at least one family through this time of recovery.

EPISODE 536 - Ritchie Shoemaker, M.D. – Part 1 of our series with the Mold Warrior (Flashback Friday: Original Air Date 4-25-2008)
Dr. Ritchie Shoemaker first joined Iaqradio as a guest back in April of 2008. Since then we have welcomed him back once a year or so to update us on his research into Chronic Inflammatory Response Syndrome (CIRS). Today we are going to replay our first show with Dr. Shoemaker and we hope to have him join us again soon for another update. Following his bio we have listed all our shows with him over the years. Ritchie Shoemaker, M. D., is a recognized leader in patient care, research and education pioneer in the field of biotoxin related illness. While illness acquired following exposure to the interior environment of water-damaged buildings (WDB) comprises the bulk of Shoemaker’s daily practice, other illnesses caused by exposure to biologically produced toxins are quite similar in their “final common pathway.” What this means is that while the illness might begin acutely with exposure to fungi, spirochetes, apicomplexans, dinoflagellates and cyanobacteria, for example, in its chronic form, each of these illnesses has similar symptoms, lab findings, and Visual Contrast Sensitivity findings. Taken together the inflammatory illness from each of these diverse sources is known as a Chronic Inflammatory Response Syndrome. We do not have a blog for Dr. Shoemakers first few shows. He joined us before Cliff started doing a weekly blog. It may take a few time listening to make sense of everything he is proposing. It was very helpful when he sent me the Bio-toxin Pathway chart to follow. Print this out and have it handy while listening to his shows and it will help you immensely.

EPISODE 534: Corbett Lunsford - The Home Performance Worskshop & The Worlds Highest Performance Tiny House on Wheels!
Corbett Lunsford, wasn't a home performance expert- he used to play piano for ballerinas. In 2008, he learned a few things very quickly: construction is unbelievably messy, most pros are over-rushed and under-paid, and homeowners end up suffering in small ways, for their entire lives in a house. None of this has to be so- we can opt out of the whole thing with performance testing. His goal is to package building performance so it can easily be understood and used by professionals and consumers alike, for better buildings worldwide. In 2009, he started teaching pros through the Building Performance Workshop and he has hosted over 300 YouTube videos and 80 interviews for the Building Performance Podcast. He also wrote the book Home Performance Diagnostics: the Guide to Advanced Testing, and developed the APT Reports software tool. In 2016 he and his wife Grace built the world's highest performance tiny house on wheels, the #TinyLab, and toured the US before settling down in Atlanta, Georgia. Along the way, they created the first TV series about home performance, Home Diagnosis, which airs on public TV across the U.S. Corbett, Grace, and their new baby went on a 13,000 mile, 34-city U.S. Tour from April 2016-January 2017 in the world's highest performance tiny house on wheels, the #TinyLab. Their mission was simple: to revolutionize the home market by teaching consumers and contractors alike to use scientific testing to prove the work gets done to quality standards. Each city on the Proof Is Possible Tour was sponsored by a local company that shared the passion for empowering homeowners and changing the game. Along the way certain cities shared in filming of the couple's TV show Home Diagnosis. They invited over 7,000 strangers into their home on the tour, and now live in Atlanta, Georgia.
