Project: Residential Fungal Assessment

Location: Fresno, CaliforniaSite Assessment

Client: Confidential Private Individual

Clark Seif Clark, Inc. (CSC) was requested to perform a fungal contamination assessment at a private residential home. A young child in the family experienced repeated, chronic fungal infections after moving into the home, resulting in the loss of an ear bone, and thus loss of hearing in one ear.

CSC approached this fungal contamination assessment as follows:

  • Interview with the parents regarding the child’s condition and diagnosis.
  • Interview with the parents regarding the condition of the home, including leak history.
  • Visual inspection and moisture survey of the home.
  • Collection of surface samples from selected locations in the home for cultureable fungal analysis.
  • Collection of dust from the home for Environmental Relative Moldiness Index Analysis (ERMI)
  • Collection of air samples from the home and outdoors for several hours for Quantitative Polymerase Chain Reaction (QPCR) analysis specific to the type of fungus that caused the child’s infection.

Result: The sample results revealed an amplification in the type of fungus that caused the child’s ear infection inside the home, both in dust and air samples. Sources of water intrusion and associated fungal growth were found during the inspection. CSC recommended that the family vacate the property until repairs could be completed at the home.

We have been more than pleased with the service provided by Clark Seif Clark Environmental. This is our second contract with them and their professionalism is top notch. I can only hope they are the successful bidder on our next contract as well.

Just want to say Thank You.
Your lunch presentation was nothing less than awesome. Your professionalism, enthusiasm, and knowledge energized the class. We look forward to a continued relationship with you and your organization. Thanks again,


I just wanted to take a moment to say Thank You for on excellent presentation on Saturday.
My technicians and I were all very impressed by what we learned, and I received some very positive feedback from the other offices in attendance. Being in the water damage business, we are frequently faced questions about mold growth from water damage customers, insurance personnel and property managers. Your presentation, visual aids and handouts were well planned and targeted to our particular interests. I think we can now address the topic with a greater sense of confidence (and a little less guesswork!). I am sending copies of your presentation packet to everyone who attended along with request for feedback. Thank you again for a well done presentation. I look forward to working with you on future projects.


Wanted to take a few minutes to express our "thanks" for the wonderful presentation that Derrick Denis gave at our office meeting last month.
We had over twenty agents in attendance and they were all very impressed with no only the knowledge, but the informative way Derrick presented the material. The Mold Disclosure Issue is one of the most confusing that we as real estate practitioners have had to deal with in a number of years. Derrick made the confusion somewhat less on our part and gave us all a better understanding if just how we should present this problem to our clients. Again, thank you for having such a wonderful person representing your company. We would not hesitate to use or recommend your firm to our clients.


Thank you again for being part of the Los Angeles County East Chapter (LACE) luncheon program last week.
We greatly appreciated your understanding of our audience and what they needed to know. Both your presentation and responses to the participants questions were right on target.
