Why David A. Henderson became an Expert Witness pertaining environmental issues associated with cleaning and restoration disputes, was because of his first courtroom testimony in a carpet dispute in Virginia, where the carpet was mislabeled as 100% nylon and would not cleanup to industry standards. When he performed a test on the fibers of the carpet, it was determined that the carpet was a blend. The judge in this case asked David what a float test was, which he explained in a simple explanation.

Then there was a North Carolina homeowner, who had a water damage event on their home, during the removal of damaged materials from the home, DAVHENCO Inc found that there were construction defects in the house, even though some damage was covered on the homeowner's insurance. When this went to court where the new contractor and David was to testify in court, the plaintiff attorney had David's report and the new contractor's new estimate. The plaintiff attorney then informed David that the original contractor agreed to pay for all the damages. 

Then in June of 2024, while David was recovering from knee surgery, a homeowner called and explained to David the mold remediation process being performed on his home. The homeowner sent pictures of the company performing the remediation process, this is when David noticed the work was not being performed to the ANSI/IICRC S520 -2024 "Standard for Professional Mold Remediation". The remediation company shortly abandoned the project leaving the homeowner with a fully damaged home.

Also, in June of 2024 an Attorney representing a family over water damage home, which developed mold because of the home was never enclosed to prevent rain to enter the structure during construction. When the Attorney had talked with David on the phone, David pointed to the construction company's on environmental inspector's lab findings that the house had water damage indicators and mycotoxin indicators, along with slightly elevated spores. The Attorney's response was "this house is water damaged".

Then there was a home that was damaged by hurricane Helene and David was called to look at the damage and was able to determine the house suffered a Category 3 water damaged. The homeowner hired a restoration company to perform the restoration services, but the house was not dried to industry standards, which this has gone to litigation in 2025.

Then in September of 2025 an Environmental Inspector forward David an email, a law firm in Tennessee wanted the Environmental Inspector to help with a mold dispute. The Inspector called David to get his permission to forward David's name to the law firm. This happened the week that David's wife entered the hospital, at which time David put his whole business on hold for the time being. David's wife asked him was he going to continue to perform inspections on the day they transferred her to hospice, and David told his wife that he going to provide expert witness work.

There are always limitations, complexities, complications and conflicts on projects that lead to litigation procedures, some of these events are the reality in the cleaning and restoration industry.

Since David's wife passing, he is dedicating this service in his wife's memory, since she had a history of working at the local newspaper helping people with their billings as the office manager.

David brings over 40 years of field experience in the cleaning and restoration industry. Also, David has a background in drafting and design with some elevation and floor plan drawings. He has used this experience and background to perform moisture mapping, wall elevation drawings to determine the level of damage to the wall, and where drying equipment was to be positioned when he performed drying services. During these over 40 years of field work, attorneys have recommended to their clients to have David inspect their apartment (a tenant-landlord dispute) for mold and in another incident an attorney had referred David to a condominium association on a complaint of a mold problem of a closed-up condominium which was later remediated. Then there was a major water damage incident at a country club, where the maintenance personnel contacted an attorney who was member and asked the attorney, who was the person that performed the drying and mitigation on his summer home. The attorney referred David to the country club. During these years of experience, David has provided services in water damage mitigation, mold remediation, mold inspections, fire and smoke damage clean up and consulting services related to water, mold, and fire & smoke damage, as well has testified in court.
