Robert Scherer

Robert Scherer


Robert Scherer, a Florida native, has over 25 years of residential and commercial construction experience in southwest Florida. He has worked in many aspects of the construction industry–from heavy commercial structural projects to high-end complete residential remodels. In the late 1980s and early 1990s, he worked as a subcontractor for several large construction companies and developers installing over 50 thousand windows and sliding glass doors in several south Florida communities as a glass & glazing contractor.

In 1996, Robert became a Florida certified building contractor. From 1996 to 2000, he was involved in numerous construction projects ranging from light commercial to the complete constructing of residential homes. In 2000, he entered the indoor air quality field as a certified mold remediator. At this point his business ideas began to be directed toward water intrusion investigations and repair procedures. Later that same year, he was introduced to infrared thermography at a mold remediation conference in Atlanta, GA. It was then that Robert realized the incredible potential of infrared thermography in the building construction industry and purchased his first infrared camera, the first in southwest Florida.

Since infrared thermography was primarily utilized in large industrial electrical applications at that time, Robert became a pioneer in the field of moisture intrusion and building defect investigations with the use of infrared thermography. Since no one had utilized infrared thermography for building science applications, he literally had to develop his own procedures and sell the idea of this technology and its applications.

Robert also has extensive training in many phases of building diagnostics, from environmental issues to cause and origin investigations. He is a Certified Indoor Environmentalist, Certified Mold Inspector, and he is certified in Advanced Building Diagnostics. Robert started his building diagnostics company using the latest in infrared cameras in 2002, specializing in building defect investigations, water infiltration testing, and cause and origin investigations of building failures. Robert and his team have completed water testing and building investigations across the nation.

Building Diagnostics Group, Inc. (BDG) exclusively uses FLIR infrared camera equipment. FLIR is the world’s leader in infrared technology. Using only high resolution, specialty thermography equipment has allowed BDG to become one of the nation’s leaders in building science thermography. With several high-resolution infrared cameras, each designed for a specific use, and a highly trained team of professionals, BDG provides the most comprehensive non-destructive building investigations available today.

Robert has been called upon numerous times to provide expert witness testimony, field evaluations, and written opinions. He has provided these services for various counties, states, and legal jurisdictions throughout the United States. In his free time Robert enjoys spending time with his family in north metro Atlanta, Georgia, where he is active in his community. If Robert doesn’t answer his phone, he is most likely logging miles on his road bike cycling the hills of north Georgia.
