Case Studies: Hazardous Materials Assessment

Case Study: Mold Assessment and Post Abatement Inspection

Shortly after evicting a commercial tenant, a client found that the restaurant had flooded because a water heater valve that had been left open. Following the initial emergency drying efforts, CSC was engaged to investigate the property to determine if the drying had been effective and to determine if any mold growth had occurred due to this incident.

Case Study: Asbestos and Lead Survey and Abatement Oversight for a Water District

A major California water district was relocating underground valves on the main feed line to above ground locations in compliance with new regulatory requirements. The underground valves were secured within vaults up to 30 feet below ground surface, located on freeways, streets, parks, golf courses. The old valves were constructed of lead and the associated gaskets were presumed to be asbestos containing material.

Case Study: IAQ Assessment for Mold, Asbestos, Smoke and Other Fire related-Contamination

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.
